    Von einem Traum getrieben (2021)
    Springer Nature | Springer Berlin Heidelberg
    Details
    Publication Date: 2024-04-04
    Description: Dieses Open-Access-Buch beschreibt das Leben und die Leistungen des norwegischen Ingenieurs und Physikers Rolf Widerøe. Zu seinen vielen bahnbrechenden Leistungen auf dem Gebiet der Beschleunigerphysik gehören unter anderem das Betatron und der Linearbeschleuniger, deren Konzepte er in seiner 27-seitigen Doktorarbeit veröffentlichte. Das Betatron revolutionierte die Bereiche der Krebsbehandlung durch Strahlentherapie und durch nicht-desktruktive Tests. Krankenhäuser auf der ganzen Welt setzen Widerøes Maschine ein, und auch die heutigen modernen Geräte zur Strahlenbehandlung basieren auf seinen Erfindungen. Die jüngste Renaissance des Linearbeschleunigers sorgt für beispiellose Röntgenintensitäten bei Freien-Elektronen-Laser-Anlagen, die weltweit in Betrieb sind. Widerøes Geschichte enthält eine gehörige Portion Dramatik, insbesondere während des Zweiten Weltkriegs, als sowohl die Deutschen als auch die Alliierten um seine Mitarbeit buhlten. Der Physiker hatte führende Positionen in multinationalen Industriekonzernen inne und war einer der Berater beim Bau des weltgrößten Kernforschungszentrums CERN in der Schweiz. Er erwarb über 200 Patente, erhielt mehrere Ehrendoktorwürden und eine Reihe internationaler Auszeichnungen. Die Autorin, Journalistin und Produzentin von Fernsehdokumentationen, erzählt in diesem Werk eine fesselnde Wissenschaftsgeschichte. Während ihrer Recherche hatte sie in mehreren Ländern Zugang zu bisher verschlossenen Archiven erhalten, die eine Fülle von neuem Material und Erkenntnissen, insbesondere im Zusammenhang mit den Kriegsjahren, lieferten. Das E-Book dieses Werks ist als Open-Access-Veröffentlichung auf springer.com erhältlich. ; Dieses Open-Access-Buch beschreibt das Leben und die Leistungen des norwegischen Ingenieurs und Physikers Rolf Widerøe.

    Climate Change, Coasts and Coastal Risk (2021)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2023-12-20
    Description: The combination of coastal climate change impacts and their effects on the ever-increasing human utilization of the coastal zone will invariably result in increasing coastal risk in the coming decades. However, while economic damage (potential consequence) caused by climate change-driven coastal inundation and erosion (potential hazard) is likely to increase, foregoing land-use opportunities in coastal regions and protecting or nourishing coasts is also costly. Managing the risk of coastline recession is therefore a balancing act. To avoid unacceptable future risks, it is imperative that risk-informed and sustainable coastal planning/management strategies are implemented sooner rather than later. This requires the development of methods for comprehensive coastal risk assessments which combine state-of-the-art consequence (or damage) modeling and coastal hazard modeling. This Special Issue contains 13 papers aimed at addressing this challenge.

    Die explorative Tympanoskopie mit Obliteration des runden/ovalen Fensters in der Behandlung des Hörsturzes (2022)
    Springer Nature | Springer Berlin Heidelberg
    Details
    Publication Date: 2022-01-15
    Description: In diesem Open-Access-Buch unternimmt der Autor den Versuch, auf das Therapieverfahren der explorativen Tympanoskopie mit Obliteration des/r runden/ovalen Fensters mit autologem Bindegewebe näher einzugehen und es in seiner Wirkung mit den verschiedenen verfahren intratympanaler Steroidinjektionen zu vergleichen. Die im Fokus stehende Operationsmethode stellt eine Therapiemethode in der Behandlung akut eingetretener, hochgradiger, idiopathischer, sensorineuraler Schwerhörigkeiten (Hörstürzen) dar. Sie kann alternativ zu der sicher zur Zeit noch in überwiegender Zahl durchgeführten intratympanalen Kortikoidgaben vorgenommen werden. Die hier zusammengetragenen Ergebnisse inklusive der Hinzufügung von Resultaten eigener Studiengruppen, bei denen die explorative Tympanoskopie zum Einsatz kam, legen nahe, dass die beschriebene Operationsmethode erfolgreich als „Second-line-Verfahren“ in der Behandlung des ausgepröägten Hörsturzes eingesetzt werden kann. Die Frage, inwiefern sie auch im „First-line-Mode“ verwendbar ist, kann durch die vorhandenen Studien noch nicht beantwortet werden. Ihrer Klärung sollte aber, initiiert durch die vorgelegten Therapierergebnisse, in der Zukunft in weiteren, prospektiv angelegten und möglichst doppel verblendeten Untersuchungsreihen mit Einbeziehung von Kontrollgruppen angestrebt werden. ; In diesem Open-Access Buch unternimmt der Autor den Versuch, auf das Therapieverfahren der explorativen Tympanoskopie mit Obliteration des/r runden/ovalen Fenster näher einzugehen und es in seiner Wirkung mit den verschiedenen beschriebenen Verfahren intratympanaler Steroidinjektionen zu vergleichen.

    Description: Dieses Buch ist eine Open Access Publikation. Der lange gehegte Traum von künstlicher Intelligenz (KI) wird in unserer Alltagswelt zunehmend Realität. Damit verbinden sich hohe gesellschaftliche Erwartungen, aber auch Sorgen hinsichtlich einer schleichenden Entmündigung des Menschen. Am Beispiel des Forschungssektors lotet dieser Band die Optionen, Entwicklungschancen und Risiken von KI-Techniken für die Zukunft des wissenschaftlichen Erkenntnisprozesses und der darauf beruhenden technischen Entwicklungen aus. Zu diesem Zweck wird zunächst der Stand der KI-Technik und ihrer Anwendungen dargestellt. Es folgen wissenschaftsphilosophische Untersuchungen zur Frage der Ersetzbarkeit des forschenden Menschen durch KI und zu erwartenden Veränderungen in der wissenschaftlichen Forschung. Weitere Abschnitte widmen sich den Folgen für die Arbeitswelt von Forschern/Forscherinnen sowie den durch KI erzeugten neuen Herausforderungen für die rechtliche Regulierung im Spannungsfeld von Wissenschaftsfreiheit und Datenschutz. Der Band schließt mit Empfehlungen für die verantwortlichen Akteure in Wissenschaft, Forschungspolitik und Gesellschaft aus interdisziplinärer Perspektive.

    Open Access and the Library (2021)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2023-12-20
    Description: Libraries are places of learning and knowledge creation. Over the last two decades, digital technology—and the changes that came with it—have accelerated this transformation to a point where evolution starts to become a revolution.The wider Open Science movement, and Open Access in particular, is one of these changes and is already having a profound impact. Under the subscription model, the role of libraries was to buy or license content on behalf of their users and then act as gatekeepers to regulate access on behalf of rights holders. In a world where all research is open, the role of the library is shifting from licensing and disseminating to facilitating and supporting the publishing process itself.This requires a fundamental shift in terms of structures, tasks, and skills. It also changes the idea of a library’s collection. Under the subscription model, contemporary collections largely equal content bought from publishers. Under an open model, the collection is more likely to be the content created by the users of the library (researchers, staff, students, etc.), content that is now curated by the library.Instead of selecting external content, libraries have to understand the content created by their own users and help them to make it publicly available—be it through a local repository, payment of article processing charges, or through advice and guidance. Arguably, this is an overly simplified model that leaves aside special collections and other areas. Even so, it highlights the changes that research libraries are undergoing, changes that are likely to accelerate as a result of initiatives such as Plan S.This Special Issue investigates some of the changes in today’s library services that relate to open access.

    BDS/GNSS for Earth Observation (2023)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2024-03-28
    Description: This reprint of the Special Issue "BDS/GNSS for Earth Observation” highlights and discusses major aspects of Earth monitoring. Among the most noteworthy works are articles presenting variations in the plasmaspheric total electron content (TEC) and correlations between the seismo-ionospheric anomalies of GNSS-TEC and earthquake energy. Those addressing the analysis of the Earth's ionosphere employ two new methods developed for determining the optimal thin layer ionospheric height in the polar regions and for estimating the multi-GNSS differential code bias without using the ionospheric function model. In addition, the troposphere is investigated using a modified interpolation method of multi-reference station tropospheric delay. There are two papers addressing precise orbit determination, employing the Haiyang-2b altimetry satellite and GRACE-FO antenna phase center modeling. Works on GNSS signals are also published, with variations in multi-channel differential code biases from new BDS-3 signal observations, and the modelling and assessment of a new triple-frequency IF1213 PPP with BDS/GPS. Furthermore, GNSS precipitable water vapor (PWV) and its applications are discussed with regard to individual station meteorological data, while three other works examine improvements in iGNSS-R ocean altimetric precision, maritime multiple moving target detection using multiple-BDS radar, and a regional groundwater storage anomaly by combining GNSSs and surface mass load data. Lastly, a review addressing the application of multi-GNSS for Earth observation and its emerging applications is presented.

    Multi-Sensor Systems and Data Fusion in Remote Sensing (2023)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2024-04-11
    Description: Remote sensing is developing rapidly due to progress in many interconnected fields. It includes the emergence of new sensors, development of sophisticated platforms for those sensors, and advances in signal and data processing. The progress in the fields of radar, optoelectronic, acoustic, magnetic, chemical, and other sensors is stunning. Whereas the mentioned sensors are currently more sensitive and accurate, have improved resolutions, data rates, and dynamical ranges, they still have their limitations. The utilization of multi-sensor systems and joint processing of their signals or data has long been considered an effective solution for reducing the disadvantages and best utilizing their strengths. The emergence of new types of sensors creates an opportunity for scientists and engineers to develop new and more capable integrated multi-sensor systems. It is necessary to mention that the users’ expectations with respect to the size of the observed area or volume, data resolution, accuracy, speed of operation, and functionality of remote sensing systems are still increasing. Extended frequency bands, improved resolutions, and data rates of the new sensors as well as the common use of distributed sensors increase the influx of data in contemporary multi-sensor systems. These facts pose new challenges for the data fusion algorithms that must often employ the newest achievements from the areas of big data mining, statistical estimation, artificial intelligence, etc. This reprint provides a fresh insight into the newest developments in the fields of multi-sensor systems and data fusion.

    Remote Sensing of Precipitation: Volume 2 (2021)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2024-04-11
    Description: Precipitation is a well-recognized pillar in global water and energy balances. An accurate and timely understanding of its characteristics at the global, regional, and local scales is indispensable for a clearer understanding of the mechanisms underlying the Earth’s atmosphere–ocean complex system. Precipitation is one of the elements that is documented to be greatly affected by climate change. In its various forms, precipitation comprises a primary source of freshwater, which is vital for the sustainability of almost all human activities. Its socio-economic significance is fundamental in managing this natural resource effectively, in applications ranging from irrigation to industrial and household usage. Remote sensing of precipitation is pursued through a broad spectrum of continuously enriched and upgraded instrumentation, embracing sensors which can be ground-based (e.g., weather radars), satellite-borne (e.g., passive or active space-borne sensors), underwater (e.g., hydrophones), aerial, or ship-borne.

    Precise Point Positioning with GPS, GLONASS, BeiDou, and Galileo (2023)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2024-03-28
    Description: The potential of global navigation satellite systems (GNSSs) as an efficient tool in providing precise positioning has been widely recognized. In particular, the precise point positioning (PPP) technique is receiving increasing interest due to its cost-effectiveness, global coverage, and high accuracy. In addition, the emergence of multiple satellite navigation systems, including BDS, Galileo, modernized GPS, and GLONASS, brings great opportunities and challenges for PPP. For instance, the additional frequency as well as the new signal of BDS-3 and Galileo enables the fast convergence of PPP by efficient ambiguity resolution (AR). More recently, besides the standard point positioning, BDS, Galileo, as well as QZSS have also provided the satellite-based PPP service. Obviously, the development of multi-frequency multi-GNSS and their built-in PPP service has popularized the use of PPP as an efficiency technique in navigation, timing, as well as geoscience applications.

    Human Mobility, Spatiotemporal Context, and Environmental Health: Recent Advances in Approaches and Methods (2021)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2023-12-21
    Description: Environmental health researchers have long used concepts like the neighborhood effect to assessing people’s exposure to environmental influences and the associated health impact. However, these are static notions that ignore people’s daily mobility at various spatial and temporal scales (e.g., daily travel, migratory movements, and movements over the life course) and the influence of neighborhood contexts outside their residential neighborhoods. Recent studies have started to incorporate human mobility, non-residential neighborhoods, and the temporality of exposures through collecting and using data from GPS, accelerometers, mobile phones, various types of sensors, and social media. Innovative approaches and methods have been developed. This Special Issue aims to showcase studies that use new approaches, methods, and data to examine the role of human mobility and non-residential contexts on human health behaviors and outcomes. It includes 21 articles that cover a wide range of topics, including individual exposure to air pollution, exposure and access to green spaces, spatial access to healthcare services, environmental influences on physical activity, food environmental and diet behavior, exposure to noise and its impact on mental health, and broader methodological issues such as the uncertain geographic context problem (UGCoP) and the neighborhood effect averaging problem (NEAP). This collection will be a valuable reference for scholars and students interested in recent advances in the concepts and methods in environmental health and health geography.

    Fitness Assessment, Athlete’s Monitoring Cycle and Training Interventions in Team Sports (2022)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2024-04-01
    Description: Team sports training are progressively growing, and thus challenging strength and conditioning coaches and head coaches. As part of a well-prepared training strategy, it is important to establish a functional relationship among fitness assessment, load, and well-being monitoring and readiness analysis to identify the consequences of training stimulus for players. Each of these topics has already been isolated in research; however, it is important to bridge the gap between them and establish a greater and more comprehensive approach among fitness adaptations, training monitoring, and specific interventions performed. This may help us to achieve a clearer view of the big picture in terms of the consequences for players, such as, considering their exposure to successful biological adaptations or less successful cases, including illness or injuries. As it is clear that more research should be performed on the relationship among these dimensions and topics, the aim of the Special Issue on "Fitness Assessment, Athlete’s Monitoring Cycle and Training Interventions in Team Sports" was to publish high-quality original investigations, systematic reviews, and meta-analysis in the research field of team sports. We have published 22 articles that cover the topics of performance assessment and relationships between fitness measures; training load monitoring, well-being, and readiness in team sports;training interventions; complementary strategies for performance (e.g., nutrition, supplementation, psychology, injury preventions, and recovery); and determinants of illness and injuries in players.

    Indoor Positioning and Navigation (2022)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2024-04-09
    Description: In recent years, rapid development in robotics, mobile, and communication technologies has encouraged many studies in the field of localization and navigation in indoor environments. An accurate localization system that can operate in an indoor environment has considerable practical value, because it can be built into autonomous mobile systems or a personal navigation system on a smartphone for guiding people through airports, shopping malls, museums and other public institutions, etc. Such a system would be particularly useful for blind people. Modern smartphones are equipped with numerous sensors (such as inertial sensors, cameras, and barometers) and communication modules (such as WiFi, Bluetooth, NFC, LTE/5G, and UWB capabilities), which enable the implementation of various localization algorithms, namely, visual localization, inertial navigation system, and radio localization. For the mapping of indoor environments and localization of autonomous mobile sysems, LIDAR sensors are also frequently used in addition to smartphone sensors. Visual localization and inertial navigation systems are sensitive to external disturbances; therefore, sensor fusion approaches can be used for the implementation of robust localization algorithms. These have to be optimized in order to be computationally efficient, which is essential for real-time processing and low energy consumption on a smartphone or robot.

    Die Zukunft zwischen Goethezeit und Realismus (2021)
    Springer Nature | Springer Berlin Heidelberg
    Details
    Publication Date: 2024-03-27
    Description: Dieses Open-Access-Buch geht der Zeitreflexion im Feld der Novellistik nach und ergründet Erzählstrategien und -logiken der literarischen Vertextung von ‚Zeit‘, ihre funktionale Einbindung wie auch ihre selbstreflexive und poetologische Gestaltung in Texten. Die Grundlage bildet ein fundiertes, semiotisches Analyseinstrumentarium. Berücksichtigt wird eine breite Textauswahl mit Werken unter anderem von Büchner, Eichendorff, Gutzkow, Hauff, Hebbel, Mundt, Stifter und Tieck. Den historischen Abschnitt zwischen Goethezeit und Realismus kennzeichnet ein Selbstverständnis als Zwischenphase, in der merklich etwas zu Ende geht, ohne dass bereits etwas Neues begonnen hätte. Verankert ist dieser Problemkomplex in einer epocheneigenen Reflexion von Zeit, deren Spezifik in der Verbreiterung des Zukunftshorizontes und dem Auseinanderklaffen von Zukunftsvorstellung und -realisierung liegt. Dabei stellt sich heraus: Die Zukunft als epistemischer Dreh- und Angelpunkt der Zwischenphase ist hochgradig relevant, flexibel und imponderabel. Der Autor: Stephan Brössel forscht und lehrt als Privatdozent und Akademischer Rat a. Z. am Germanistischen Institut der WWU Münster, Abteilung Neuere deutsche Literatur, Schwerpunkt: Literatur und Medien.

    Measurement and Control of Charged Particle Beams (2021)
    Springer Nature | Springer Berlin Heidelberg
    Details
    Publication Date: 2024-04-05
    Description: From the reviews: "This book is a very welcome and valuable addition to the accelerator literature. As noted by the authors, there is relatively little material in the book specifically for low-energy machines, but industrial users may still find it useful to read." Cern Courier ; The intent of this book is to bridge the link between experimental obser­ vations and theoretical principles in accelerator physics. The methods and concepts, taken primarily from high energy accelerators, have for the most part already been presented in internal reports and proceedings of accelera­ tor conferences, a portion of which has appeared in refereed journals. In this book we have tried to coherently organize this material so as to be useful to designers and operators in the commissioning and operation of particle accelerators. A point of emphasis has been to provide, wherever possible, experimental data to illustrate the particular concept under discussion. Of the data pre­ sented, most are collected from presently existing or past accelerators and we regret the problem of providing original data some of which appear in less accessible publications - for possible omissions we apologize. Regarding the uniformity of the text, particularly with respect to symbol definitions, we have taken the liberty to edit certain representations of the data while trying to maintain the essence of the presented observations. Throughout the text we have attempted to provide references which are readily available for the reader.; This reference and advanced textbook is the first comprehensive and systematic review of all methods used for the measurement, correction, and control of the beam dynamics of modern particle accelerators. Based on material presented in several lectures at the US Particle Accelerator School, the text is intended for graduate students starting research or work in the field of beam physics. Relativistic beams in linear accelerators and storage rings provide the focus. After a review of linear optics, the text addresses basic and advanced techniques for beam control, plus a variety of methods for the manipulation of particle-beam properties. In each case, specific procedures are illustrated by examples from operational accelerators. The book also treats special topics such as injection and extraction methods, beam cooling, spin transport, and polarization. Problems and solutions enhance the books usefulness in graduate courses.

    Bistatic HF Radar (2021)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2024-04-11
    Description: The proliferation of HF radar systems for ocean remote sensing and maritime surveillance continues apace, with hundreds of such radars now deployed around the world. The overwhelming majority of these radars operate in the conventional monostatic configuration, with the transmitting and receiving systems collocated or closely spaced; this simple geometry has obvious advantages in terms of cost, siting requirements, communications, maintenance, signal processing, and echo interpretation, and it has been adopted by HF radars exploiting line-of-sight, surface wave, and skywave propagation modalities. All these considerations notwithstanding, in some circumstances there can be compelling reasons to implement bistatic configurations, defined as geometries in which the separation between transmitter and receiver is comparable with the range to the zones being interrogated. Factors that can drive this decision include energy budget, desire to exploit hybrid propagation modes, scattering characteristics of the targets of interest, properties of the clutter, survivability, and covertness. This book, a compilation of papers by leading researchers in the field, offers a panoramic account of the state of the art in bistatic HF radar. Topics covered include system design, HF propagation and scattering, signal processing, echo interpretation, and applications in the maritime domain. Supported with extensive references to the literature, this book should serve as an essential source for practitioners keen to expand the capabilities of their HF radar systems.

    Nuclear and Radiological Emergencies in Animal Production Systems, Preparedness, Response and Recovery (2021)
    Springer Nature | Springer Berlin Heidelberg
    Details
    Publication Date: 2024-04-01
    Description: This Open Access volume explains how major nuclear and radiological emergencies (NREs) can have implications at local, national and international level. The response to NREs requires a competent decision-making structure, clear communication and effective information exchange. National veterinary services have the responsibility to plan, design and manage animal production system in their countries. These activities cover animal health, animal movement control, production control and improvement, and control of the products of animal origin before their placement on the market. Release of radionuclides after NREs can cause substantial contamination in the animal production systems. Critical responsibility of veterinary authorities is therefore to prevent such contamination, establish early response mechanisms to mitigate the consequences and prevent placement of contaminated products of animal origin on the market for human consumption. This work summarizes the critical technical points for effective management of NREs for national veterinary services.

    GNSS, Space Weather and TEC Special Features (2023)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2024-04-11
    Description: In the domain of electronic navigation, satellite navigation (GNSS) is one of the most important complex modern systems. GNSS is a key aspect of infrastructure which supports the development and improvement of power grid systems, banking operations, global transportation systems, and global communication systems. Today, GNSS requires the use of several positioning networks and sensors, such as radio networks and MEMS. The Earth’s atmosphere, particularly the ionosphere and troposphere, can be seen as a huge laboratory where multiple processes and phenomena directly affecting the propagation of EM waves occur. Like all complex systems, GNSS technology has also gone through certain evolutionary stages. Factors affecting the future evolution of GNSS technology include the appearance of new signals and frequencies, complementary technologies in use, etc., but in the domain of GNSS technologies, it is essential to study the impact of space weather on GNSS systems. A key part of research related to GNSS technologies is the vertical TEC distribution and anomalies related to earthquakes and volcanic eruptions on Earth. There are many challenges that need to be addressed because they affect reliability, accuracy, and all other essential parameters of GNSS systems. It addresses some of these issues by publishing manuscripts which study GNSS risk assessment, different effects of space weather disturbances on the operation of GNSS systems, environmental impacts on the operation of GNSS systems, GNSS positioning error budgets, TEC special features in volcano eruptions, and similar topics.

    Publication Date: 2023-07-14
    Description: Human activity recognition (HAR) and human behavior recognition (HBR) play increasingly important roles in the digital age. High-quality sensory observations applicable to recognizing users’ activities and behaviors, including electrical, magnetic, mechanical (kinetic), optical, acoustic, thermal, and chemical biosignals, are inseparable from sensors’ sophisticated design and appropriate application. Traditional sensors suitable for HAR and HBR, including external sensors for smart homes, optical sensors such as cameras for capturing video signals, and bioelectrical, biomagnetic, and biomechanical sensors for wearable applications, have been studied and verified adequately. They continue to be researched in depth for more effective and efficient usage, and brand-new areas facilitated by sensor-based HAR/HBR are emerging, such as interactive edutainment, single-motion duration analysis, time series information retrieval, handcrafted and high-level feature design, and fall detection. Meanwhile, innovative sensor research for HAR or HBR is also very active in the academic community, including new sensors appropriate for HAR/HBR, new designs and applications of the above-mentioned traditional sensors, and the usage of non-traditional HAR-/HBR-related sensor types, among others.

    Genetics and Genomics of Forest Trees (2021)
    MDPI - Multidisciplinary Digital Publishing Institute
    Details
    Publication Date: 2024-04-05
    Description: Forest tree genetics and genomics are advancing at an accelerated rate, thanks to recent developments in high-throughput, next-generation sequencing capabilities, and novel biostatistical tools. Population and landscape genetics and genomics have seen the rise of new approaches implemented in large-scale studies that employ the use of genome-wide sampling. Such studies have started to discern the dynamics of neutral and adaptive variation in nature and the processes that underlie spatially explicit patterns of genetic and genomic variation in nature. The continuous development of genetic maps in forest trees and the expansion of QTL and association mapping approaches contribute to the unravelling of the genotype-phenotype relationship and lead to marker-assisted and genome-wide selection. However, major challenges lie ahead. Recent literature suggests that species demography and genetic diversity have been affected both by climatic oscillations and anthropogenically induced stresses in a way calls into question the possibility of future adaptation. Moreover, the pace of contemporary environmental change presents a great challenge to forest tree populations and their ability to adapt, taking into consideration their life history characteristics. Several questions emerge that include, but are not limited to, the interpretation of forest tree genome surveillance and their structural/functional properties, the adaptive and neutral processes that have shaped forest tree genomes, the analysis of phenotypic traits relevant to adaptation (especially adaptation under contemporary climate change), the link between epigenetics/epigenomics and phenotype/genotype, and the use of genetics/genomics as well as genetic monitoring to advance conservation priorities.

    Publication Date: 2024-04-14
    Description: Gegenstand dieser Open Access Publikation sind die Auswirkungen automatisierter und vernetzter Fahrzeuge auf die Europäische Stadt sowie die Voraussetzungen, unter denen diese Technologie einen positiven Beitrag zur Stadtentwicklung leisten kann. Dabei vertreten die Autorinnen und Autoren zwei Thesen, die im wissenschaftlichen Diskurs bislang wenig Beachtung fanden: Automatisierte und vernetzte Fahrzeuge werden sich für lange Zeit nicht in allen Teilräumen der Stadt durchsetzen. Dies hat zur Folge, dass bislang angenommene Wirkungen - von der Verkehrssicherheit bis zur Verkehrsleistung sowie räumliche Effekte - neu bewertet werden müssen. Um einen positiven Beitrag dieser Technologie zur Mobilität der Zukunft sicherzustellen, müssen verkehrs- und siedlungspolitische Regulationen weiterentwickelt werden. Etablierte territoriale, institutionelle und organisatorische Grenzen sind zeitnah zu hinterfragen. Trotz oder wegen der bestehenden großen Unsicherheiten befinden wir uns am Beginn einer Phase des Gestaltens - in der Technologieentwicklung, aber eben auch in der Politik, Stadtplanung, Verwaltung und der Zivilgesellschaft.

    Comparison of ionospheric scintillation models with experimental data for satellite navigation applications (2006)
    INGV
    Details
    Publication Date: 2021-05-17
    Description: A comparison between two of the most used scintillation models and experimental data is presented. The experimental data have been derived from a GPS scintillation monitor developed at Cornell University and placed in Tucuman (Argentina), under the peak of the anomaly. The models used (GISM and WBMOD) have been run for the geophysical conditions corresponding to the measurements. The comparison is done by subdividing the information on the basis of an ionospheric grid of 5°×5° surface square boxes. The comparison has been performed for several local times, from 18 LT until 04 LT. Here, only a few cases of particular interest are shown. The goal is to understand if the models are able to forecast actual scintillation morphology (from the satellite navigation systems point of view) and if they could be used to yield an estimate of scintillation effects on satellite navigation systems.

    Lo studio delle deformazioni del suolo nell'area di Bojano nel periodo 2004-2006 (2008)
    INGV
    Details
    Publication Date: 2017-04-04
    Description: In questa nota sono riportati i risultati ottenuti da indagini geodetiche effettuate nell’area del Sannio-Matese nell’ambito di una Convenzione triennale perfezionata tra l’Assessorato ai Lavori Pubblici della Regione Molise e l’INGV-OV, rivolta all’individuazione di eventuali fenomeni deformativi del suolo in atto nel comune di Bojano (CB). Lo studio, condotto nel periodo 2004-2006, ha visto la progettazione di una rete geodetica nell’area del Comune di Bojano, avente come riferimento il Cs 104 della Linea 80 IGMI corrispondente al Cs LBO/AIGM in Carta, e la materializzazione di vertici GPS, caposaldi di livellazione e l’installazione di Dry Tilt. Le misure di livellazione sull’intera rete, relative al caposaldo di riferimento, hanno evidenziato un generale trend in subsidenza nel bacino di Bojano connesso, con buona probabilità, alle oscillazioni stagionali della falda. I risultati dellemisure sui vertici della rete GPS sono in buon accordo con quelli ottenuti dalle misure di livellazione, evidenziando un trend in subsidenza nella piana di Bojano e nell’area delle sorgenti del Biferno. Le stime dell’inclinazione del suolo ottenute attraverso l’applicazione della tecnica dei dry-tilt hanno delineato un quadro deformativo relativo alla zona cittadina di Bojano consistente in una inclinazione del suolo nel quadrante ENE.

    Monitoraggio geodetico delle deformazioni del suolo in area sismogenetica: la rete GPS dello Stretto di Messina (2007)
    INGV
    Details
    Publication Date: 2017-04-04
    Description: Il terremoto del 1908 che ha distrutto le città di Reggio Calabria e Messina costituisce il primo esempio in cui, attraverso l’utilizzo di dati geodetici, è stato possibile ricostruire il campo di deformazione verticale collegato al catastrofico evento. In questo lavoro vengono riassunti i principali risultati della ricerca incentrata sulla caratterizzazione cinematica dell’area dello Stretto di Messina e vengono presentati i primi risultati della rete misurata con modalità GPS nel corso del 2001 e del 2003 nella stessa area. Questi risultati confermano l’importanza dell’approfondimento delle attività di monitoraggio geodetico tra il complesso peloritano calabro e quello siciliano, anche allo scopo di chiarire le numerose ambiguità riscontrate, in questi anni, nella definizione delle strutture che hanno originato il terremoto del 1908.

    Georeferenced cartography dataset of the La Fossa crater fumarolic field at Vulcano Island (Aeolian Archipelago, Italy): conversion and comparison of data from local to global positioning methods (2011)
    INGV
    Details
    Publication Date: 2017-04-04
    Description: The present study illustrates the procedures applied for the coordinate system conversion of the historical fumarole positions at La Fossa crater, to allow their comparison with newly acquired global positioning system (GPS) data. Due to the absence of ground control points in the field and on both the old Gauss Boaga and the new UTM WGS 1984 maps, we had to model the transformation errors between the two systems using differential GPS techniques. Once corrected, the maps show a residual Easting shifting, due to erroneous georeferencing of the original base maps; this is corrected by morphological comparative methods. The good correspondence between the corrected positions of the historical data and the results of the new GPS survey that was carried out in 2009 highlights the good quality of the old surveys, although they were carried out without the use of accurate topographical instruments.

    Measuring GNSS ionospheric total electron content at Concordia, and application to L-band radiometers (2013)
    INGV
    Details
    Publication Date: 2017-04-04
    Description: In the framework of the project BIS - Bipolar Ionospheric Scintillation and Total Electron Content Monitoring, the ISACCO-DMC0 and ISACCO-DMC1 permanent monitoring stations were installed in 2008. The principal scope of the stations is to measure the ionospheric total electron content (TEC) and to monitor the ionospheric scintillations, using high-sampling-frequency global positioning system (GPS) ionospheric scintillation and TEC monitor (GISTM) receivers. The disturbances that the ionosphere can induce on the electromagnetic signals emitted by the Global Navigation Satellite System constellations are due to the presence of electron density anomalies in the ionosphere, which are particularly frequent at high latitudes, where the upper atmosphere is highly sensitive to perturbations coming from outer space. With the development of present and future low-frequency space-borne microwave missions (e.g., Soil Moisture and Ocean Salinity [SMOS], Aquarius, and Soil Moisture Active Passive missions), there is an increasing need to estimate the effects of the ionosphere on the propagation of electromagnetic waves that affects satellite measurements. As an example, how the TEC data collected at Concordia station are useful for the calibration of the European Space Agency SMOS data within the framework of an experiment promoted by the European Space Agency (known as DOMEX) will be discussed. The present report shows the ability of the GISTM station to monitor ionospheric scintillation and TEC, which indicates that only the use of continuous GPS measurements can provide accurate information on TEC variability, which is necessary for continuous calibration of satellite data.

    Continuous photometric observations at ENEA base in Lampedusa to estimate precipitable water (2006)
    INGV
    Details
    Publication Date: 2019-11-04
    Description: Water vapour is a variable component of the atmosphere both in space and time. It is one of the most important components because of its effects in many fi elds: Meteorology, Climatology, Remote Sensing, Energy-Budget, Hydrology, etc. This work compares radiometric (sun photometer) readings, Global Positioning System (GPS) data and a meteorological model forecasted data. The aim is to understand if GPS measurements may help Numerical Weather Prediction (NWP) models. It is well known that GPS measurements are affected by the so-called tropospheric delay. Part of it, the so-called wet delay is related mainly to the amount of water vapour along the path of the GPS signal through the troposphere. Precise knowledge of the abundance of water vapour, in space and time, is important for NWP model because water vapour is the predecessor of precipitation. Despite the high variability of water vapour compared to other meteorological fi elds, like pressure and wind, water vapour observations are scarce, so that additional measurements of water vapour are expected to benefi t meteorology. A new sun photometer, which is part of the AERONET (AErosol and RObotic NETwork) program, has been installed at the ENEA (Ente per le Nuove tecnologie, l'Energia e l'Ambiente) base of Lampedusa Island. The sun photometer is quite close (less then 4 km) to an ASI (Agenzia Spaziale Italiana) GPS permanent receiver. A long record (summer period of the year 2000) of sun photometric measurements is available for the station at Lampedusa. We found that the GPS and sun photometric data are better correlated (std. dev. about 10 mm for the wet delay) than are the GPS measurements with the NWP model predictions. This is an indication that GPS delay data may contain information useful for weather prediction.

    Testing of the transionospheric radiochannel using data from the global GPS network (2006)

    Publication Date: 2019-11-04
    Description: Using the international ground-based network of two-frequency receivers of the GPS navigation system provides a means of carrying out a global, continuous and fully-computerized monitoring of phase fluctuations of signals from satellite-borne radio engineering systems caused by the Earth's inhomogeneous and nonstationary ionosphere. We found that during major geomagnetic storms, the errors of determination of the range, frequency Doppler shift and angles of arrival of transionospheric radio signals exceeds that for magnetically quiet days by one order of magnitude as a minimum. This can be the cause of performance degradation of current satellite radio engineering navigation, communication and radar systems as well as superlong-baseline radio interferometry systems.

    Theory of second order stationary random processes applied to GPS coordinate time-series (2019)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2019-12-05
    Description: The analysis of Global Positioning System (GPS) coordinates time series is a valuable tool in quantifying crustal deformations. The longer continuous GPS time series allow estimation of nonlinear signatures. As a matter of fact, besides the linear and periodic behaviors, other relevant signals are present in such time series as the so-called transient deformations. They can be related to, e.g., slow slip events, which play a crucial role in studying fault mechanisms. To give reliable estimates of these signals, an appropriate and rigorous approach for defining the deterministic and the stochastic models of the data is needed. We prove that the theory of the second order stationary random process (SOSRP) can be used to describe the stochastic behavior of the daily GPS time series. In particular, the second order stationarity condition has to be verified for the daily GPS coordinate time series to be described as a SOSRP. This method has been already used for modeling the gravity field of the earth and in predicting/filtering problems, and this work shows that it can also be useful for characterizing the colored noise in the GPS time series.

    A three-dimensional time-dependent algorithm for ionospheric imaging using GPS (2006)
    INGV
    Details
    Publication Date: 2019-11-04
    Description: Global Positioning System (GPS) satellite receivers provide a world-wide network of phase and group delay measurements. The combination of two-frequency measurements can be used to derive the integral of the electron concentration along each satellite-to-receiver path, a parameter known as the Total Electron Content (TEC). At this stage these slant TEC data are diffi cult to interpret as they originate from a combination of a temporally changing ionosphere and spatially changing observation geometry. In this paper TEC data are inverted to evaluate the underlying distribution and time evolution of electron concentration. Accordingly, a new three-dimensional, time-dependent algorithm is presented here for imaging ionospheric electron concentration using GPS signals. The inversion results in a three-dimensional movie rather than a static image of the electron-concentration distribution. The technique is demonstrated using simulated ground-based GPS data from actual measurement geometry over Europe.

    Detection of meteorological inconsistencies by GPS (2006)
    INGV
    Details
    Publication Date: 2019-11-04
    Description: GPS observations, distances from satellites to receivers and meteorological conditions in neutral atmosphere are known to obey a constraint, which provides a residual or in other words a quality index. A method is discussed which provides a residual epoch by epoch in near real time. In general, distribution of residuals during several consecutive epochs belonging to the same satellites, allows estimates of a mean and a standard deviation of mean. Under normal meteorological conditions distribution of residuals appears to be consistent with zero mean as expected. However, consecutive residuals sometimes appear to have a mean different from zero by more than three standard deviations of mean. Such signifi cant consecutive epochs provide a warning of existing inconsistencies among GPS observations, distances from satellites to receivers as obtained by orbital information, meteorological conditions above receivers (as obtained by ground measurements or by extrapolation of meteorological analysis). A procedure has been set up which warns about these inconsistencies in near real time.

    Description: GPS, digital photogrammetry and laser scanning techniques have been applied and compared in the frame of the studies of two complex landslides located in the Emilia-Romagna Region (Northern Italy). The three approaches, characterized by different accuracies, applicability and costs, have demonstrated to be efficient tools to define Digital Elevation Models computed in the same reference system and able to provide data on the landslide motion. The results described in the paper indicate the present low level of landslide activity in recent years. Reliability, costs and execution times of the applied surveying methods are shown and discussed in this paper.

    Modelling and management of a Mediterranean karstic coastal aquifer under the effects of seawater intrusion and climate change (2016)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2017-04-04
    Description: The study and management of the groundwater resources of a large, deep, coastal, karstic aquifer represent a very complex hydrogeological problem. Here, this problem is successfully approached by using an equivalent porous continuous medium (EPCM) to represent a karstic Apulian aquifer (southern Italy). This aquifer, which is located on a peninsula and extends to hundreds of metres depth, is the sole local source of high-quality water resources. These resources are at risk due to overexploitation, climate change and seawater intrusion. The model was based on MODFLOW and SEAWAT codes. Piezometric and salinity variations from 1930 to 2060 were simulated under three past scenarios (up to 1999) and three future scenarios that consider climate change, different types of discharge, and changes in sea level and salinity. The model was validated using surveyed piezometric and salinity data. An evident piezometric drop was confirmed for the past period (until 1999); a similar dramatic drop appears to be likely in the future. The lateral intrusion and upconing effects of seawater intrusion were non-negligible in the past and will be considerable in the future. All phenomena considered here, including sea level and sea salinity, showed non-negligible effects on coastal groundwater.

    Publication Date: 2019-11-04
    Description: The Hyblean plateau (Southeastern Sicily)is characterised by three main tectonic structural trends: the first, NNW-SSE striking,runs on the eastern most part of the plateau and is linked to the Hyblean-Maltese fault system; the second runs along the western part of the plateau with a NNE-SSW direction and is characterised by a sinistral strike slip motion,like the Scicli fault;the third ENE-WSW striking, characterises the northernmost part of the area,including the Scordia-Lentini graben.We analysed GPS data collected in a dense network located in the northern area of the Hyblean plateau during 1998 and 2000, between the towns of Catania and Syracuse. Data from Noto,Matera and Cagliari IGS stations,were included in the processing to connect this network to the International Terrestrial Reference Frame (ITRF).The comparison between 1998 and 2000 data sets shows an average northward motion of the GPS stations located south of the Gela-Catania foredeep.Site velocities decrease from south to north and show a weak internal deformation of the northernmost part of the Hyblean plateau.

    GPS Zenith Total Delays and Precipitable Water in comparison with special meteorological observations in Verona (Italy)during MAP-SOP (2006)
    INGV
    Details
    Publication Date: 2019-11-04
    Description: Continuous meteorological examination of the Pre-Alpine zones in Northern Italy (Po Valley)is important for determination of atmospheric water cycles connected with floods and rainfalls.During a special meteorological observing period (MAP-SOP),radiosounding and other measurements were made in the site of Verona (Italy). This paper deals with Zenith Total Delay (ZTD)and Precipitable Water (PW)comparisons obtained by GPS, radiosounding and other meteorological measurements.PW and ZTD from ground-based GPS data in comparisonwith classical techniques (e.g.,WVR,radiosounding)from recent literature present an accurate tool for use in meteorology applications (e.g.,assimilation in Numerical Weather Prediction (NWP)models on short-range precipitation forecasts).Comparison of such ZTD for MAP-SOP showed a standard deviation of 16.1 mm and PW comparison showed a standard deviation of 2.7 mm,confirming the accuracy of GPS measurements for meteorology applications.In addition,PW data and its time variation are also matched with time series of meteorological situations.Those results indicate that changes in PW values could be connected to changes in air masses,i.e.to passages of both cold and warm fronts.There is also a correlation between precipitation, forthcoming increase and the following decrease of PW.A good agreement between oscillation of PW and precipitation and strong cyclonic activities is found.

    Precise point positioning with GPS and Galileo broadcast ephemerides (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-12-16
    Description: For more than 20 years, precise point positioning (PPP) has been a well-established technique for carrier phase-based navigation. Traditionally, it relies on precise orbit and clock products to achieve accuracies in the order of centimeters. With the modernization of legacy GNSS constellations and the introduction of new systems such as Galileo, a continued reduction in the signal-in-space range error (SISRE) can be observed. Supported by this fact, we analyze the feasibility and performance of PPP with broadcast ephemerides and observations of Galileo and GPS. Two different functional models for compensation of SISREs are assessed: process noise in the ambiguity states and the explicit estimation of a SISRE state for each channel. Tests performed with permanent reference stations show that the position can be estimated in kinematic conditions with an average three-dimensional (3D) root mean square (RMS) error of 29 cm for Galileo and 63 cm for GPS. Dual-constellation solutions can further improve the accuracy to 25 cm. Compared to standard algorithms without SISRE compensation, the proposed PPP approaches offer a 40% performance improvement for Galileo and 70% for GPS when working with broadcast ephemerides. An additional test with observations taken on a boat ride yielded 3D RMS accuracy of 39 cm for Galileo, 41 cm for GPS, and 27 cm for dual-constellation processing compared to a real-time kinematic reference solution. Compared to the use of process noise in the phase ambiguity estimation, the explicit estimation of SISRE states yields a slightly improved robustness and accuracy at the expense of increased algorithmic complexity. Overall, the test results demonstrate that the application of broadcast ephemerides in a PPP model is feasible with modern GNSS constellations and able to reach accuracies in the order of few decimeters when using proper SISRE compensation techniques.

    Age and origin of groundwater resources in the Ararat Valley, Armenia: a baseline study applying hydrogeochemistry and environmental tracers (2021)

    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-08-08
    Description: Within the Ararat Valley (Armenia), a continuously growing water demand (for irrigation and fish farming) and a simultaneous decline in groundwater recharge (due to climate change) result in increasing stress on the local groundwater resources. This detrimental development is reflected by groundwater-level drops and an associated reduction of the area with artesian conditions in the valley centre. This situation calls for increasing efforts aimed at more sustainable water resources management. The aim of this baseline study was the collection of data that allows for study on the origin and age distribution of the Ararat Valley groundwater based on environmental tracers, namely stable (δ〈sup〉2〈/sup〉H, δ〈sup〉18〈/sup〉O) and radioactive (〈sup〉35〈/sup〉S, 〈sup〉3〈/sup〉H) isotopes, as well as physical-chemical indicators. The results show that the Ararat Valley receives modern recharge, despite its (semi-)arid climate. While subannual groundwater residence times could be disproved (〈sup〉35〈/sup〉S), the detected 〈sup〉3〈/sup〉H pattern suggests groundwater ages of several decades, with the oldest waters being recharged around 60 years ago. The differing groundwater ages are reflected by varying scatter of stable isotope and hydrochemical signatures. The presence of young groundwater (i.e., younger that the 1970s), some containing nitrate, indicates groundwater vulnerability and underscores the importance of increased efforts to achieve sustainable management of this natural resource. Since stable isotope signatures indicate the recharge areas to be located in the mountains surrounding the valley, these efforts must not be limited to the central part of the valley where most of the abstraction wells are located.

    Description: Die Bundesanstalt für Geowissenschaften und Rohstoffe (BGR) führte in den Jahren 2000–2014 umfangreiche (etwa 5900 km2) aerogeophysikalische Erkundungen an der niedersächsischen Nordseeküste durch. Die Aeroelektromagnetik liefert Informationen über die elektrisch leitfähigen Strukturen im Erduntergrund und ermöglicht die Unterscheidung von Süß- und Salzwasser wie auch von Tonen und Sanden. Im Landesamt für Bergbau, Energie und Geologie (LBEG) sowie am Leibniz Institut für Angewandte Geophysik (LIAG) wurden diese Daten zur Kartierung der Tiefenlage der Süß‑/Salzwassergrenze genutzt. Dadurch ist unter anderem eine detaillierte Karte der Grundwasserversalzung innerhalb der küstennahen Aquifere entlang der niedersächsischen Nordseeküste im Maßstab 1:50.000 entstanden. Diese zeigt den aktuellen Stand der Grundwasserversalzung, abgeleitet aus den gewonnenen Elektromagnetik-Modellen. Die Modelle waren auch Grundlage für eine hydraulische Modellierung der Süßwasserlinse der Nordseeinsel Borkum. Darauf aufbauende Simulationen zeigen die Entwicklung der Grundwassersituation für den Zeitraum bis 2100.

    Can Tanzania’s adaptation measures prevent future maize yield decline? A simulation study from Singida region (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-08-01
    Description: Cereal crop production in sub-Saharan Africa has not achieved the much-needed increase in yields to foster economic development and food security. Maize yields in the region’s semi-arid agroecosystems are constrained by highly variable rainfall, which may be worsened by climate change. Thus, the Tanzanian government has prioritized agriculture as an adaptation sector in its intended nationally determined contribution, and crop management adjustments as a key investment area in its Agricultural Sector Development Programme. In this study, we investigated how future changes in maize yields under different climate scenarios can be countered by regional adjusted crop management and cultivar adaptation strategies. A crop model was used to simulate maize yields in the Singida region of Tanzania for the baseline period 1980–2012 and under three future climate projections for 2020–2060 and 2061–2099. Adaptation strategies to improve yields were full irrigation, deficit irrigation, mulch and nitrogen addition and another cultivar. According to our model results, increase in temperature is the main driver of future maize yield decline. Increased respiration and phenological development were associated with lower maize yields of 16% in 2020–2060 and 20% in 2061–2099 compared to the 1980–2012 baseline. Surprisingly, none of the management strategies significantly improved yields; however, a different maize variety that was tested as an alternative coping strategy performed better. This study suggests that investment in accessibility of improved varieties and investigation of maize traits that have the potential to perform well in a warmer future are better suited for sustaining maize production in the semi-arid region than adjustments in crop management.

    Details
    Publication Date: 2023-08-01
    Description: Sao Tome and Principe is a small insular country in the west coast of Central Africa. The small dimensions of the islands and the limited natural resources put these islands under highly vulnerable to climate change. To assess the possible future impacts and risks on their agricultural activities, the high-resolution 4-km downscaled climate change projections using Eta regional climate model are used. A crop risk index (CRI) is proposed to assess the risk of climate change on cocoa (Theobroma cacao L.), pepper (Piper nigrum L. and Piper guinesse L.), taro (Colocasia esculenta (L.) Schott), and maize (Zea mays L.). The index takes into account the vulnerability to climate conditions and the crop yield in the future, and it is classified into very-high, high, moderate, low, and very-low. The climate change projections indicate increase in the risk of taro crop, partly due to thermal stress and partly due to the susceptibility to the leaf blight crop disease in taro. The risk of production of the pepper crop is very-high, mainly due to water stress. In mountain regions, the greater risk is due to the thermal stress caused by low temperatures. The cocoa crop is at risk due to water stress, mainly in the northwestern part of the Sao Tome Island, where major local production occurs. The projection indicates increase of the area with very-high risk to maize crops due to the increase of thermal stress and susceptibility to rust. In addition, in parts of the coastal regions, the risk changed from very-low to high risk, due to the low productivity potential. In general, the risks of the four major crops of Sao Tome and Principe increase in the future climate conditions.

    Climate change impacts on potential maize yields in Gambella Region, Ethiopia (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-08-01
    Description: Changing climate conditions are supposed to have particularly strong impacts on agricultural production in the tropics with strong implications on food security. Ethiopia’s economy is profoundly dominated by agriculture, contributing to around 40% of the gross domestic product. Thereby, Ethiopia is one of the most vulnerable countries to the impact of climate change and has a wide gap in regional climate change impact studies. In this study, we systematically investigate climate change impacts on yields for the Gambella region in Ethiopia, exemplarily for maize. Here, we show how yields change until 2100 for RCPs 2.6, 4.5, and 8.5 from a climate model ensemble under rainfed and irrigated conditions. While rainfed yields decrease by 15% and 14% respectively for RCPs 2.6 and 4.5, yields decrease by up to 32% under RCP 8.5. Except for RCP 8.5, yields are not further decreasing after 2040–2069. We found that temperature increase, changing soil water availability, and atmospheric CO2 concentration have different effects on the simulated yield potential. Our results demonstrate the dominance of heat response under future climate conditions in the tropical Gambella region, contributing to 85% of total yield changes. Accordingly, irrigation will lose effectiveness for increasing yield when temperature becomes the limiting factor. CO2, on the other hand, contributes positively to yield changes by 8.9% for RCP 8.5. For all scenarios, the growing period is shorted due to increasing temperature by up to 29 days for RCP 8.5. Our results suggest that new varieties with higher growing degree days are primarily required to the region for adapting to future climate conditions.

    Current and future state of groundwater salinization of the northern Elbe-Weser region (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-08-09
    Description: Salinization of the upper aquifer of the northern Elbe-Weser region almost extends to the surface. Chloride content exceeds 250 mg/l and the groundwater is therefore, according to the German Drinking Water Ordinance, not suitable as drinking water. The chloride content in the aquifer originates from early flooding with seawater which occurred during the Holocene sea level rise. Depth and extent of the salinization were mapped by airborne electromagnetic surveys and validated by groundwater analyses. In the transition zone between the marshlands and geest areas, the fresh-saline groundwater interface falls to a depth of 〉 −175 m NHN. Due to the extensive drainage of the marshlands, seepage of fresh groundwater is impeded. Instead, an upconing of the fresh-saline groundwater interface appears due to an upwardly directed hydraulic gradient. Due to climate change, chloride concentrations will increase along the coastlines. Further inland, a decrease of chloride content in near-surface groundwater will occur.

    Publication Date: 2023-06-23
    Description: Die Ergebnisse regionaler Klimaprojektionen für Deutschland weisen auf eine Zunahme der mittleren Lufttemperatur und eine innerjährliche Verschiebung der Niederschläge – mit feuchteren Wintern und trockeneren Sommern – hin. Darüber hinaus werden sich regional die Häufigkeit, Intensität und Dauer von Hitzewellen, Trockenperioden und Starkregenereignissen weiter erhöhen. Durch diese Veränderungen wird sich auch der Jahresgang der Grundwasserneubildung ändern. Als Folge dessen können sich Änderungen bei den hohen, mittleren und tiefen Grundwasserständen, Grundwasserschwankungsbreiten und dem Grundwasserdargebot ergeben. Aber nicht nur die Ressource Grundwasser wird durch die Folgen des Klimawandels betroffen. Auch die gesamte Infrastruktur – von der Förderung bis zur Verteilungsleitung zum Kunden – kann beeinträchtigt werden. Neben den direkten Einflüssen sind auch indirekte Beeinflussungen durch Kaskadeneffekte – beispielsweise ausgehend vom Energiesektor – möglich. Darum gilt es integrative, ganzheitliche und systemische Lösungen zu erarbeiten, um die Funktionalität der kritischen Infrastruktur dauerhaft auch unter Berücksichtigung der Folgen des Klimawandels gewährleisten zu können.

    Climate change vulnerability, water resources and social implications in North Africa (2020)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-06-21
    Description: North Africa is considered a climate change hot spot. Existing studies either focus on the physical aspects of climate change or discuss the social ones. The present article aims to address this divide by assessing and comparing the climate change vulnerability of Algeria, Egypt, Libya, Morocco, and Tunisia and linking it to its social implications. The vulnerability assessment focuses on climate change exposure, water resources, sensitivity, and adaptive capacity. The results suggest that all countries are exposed to strong temperature increases and a high drought risk under climate change. Algeria is most vulnerable to climate change, mainly due to the country’s high sensitivity. Across North Africa, the combination of climate change and strong population growth is very likely to further aggravate the already scarce water situation. The so-called Arab Spring has shown that social unrest is partly caused by unmet basic needs of the population for food and water. Thus, climate change may become an indirect driver of social instability in North Africa. To mitigate the impact of climate change, it is important to reduce economic and livelihood dependence on rain-fed agriculture, strengthen sustainable land use practices, and increase the adaptive capacity. Further, increased regional cooperation and sub-national vulnerability assessments are needed.

    Extending access to localizer performance with vertical guidance approaches by means of an SBAS to GBAS converter (2020)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-06-21
    Description: Currently, many commercial airline aircraft cannot perform three-dimensionally guided approaches based on satellite-based augmentation systems. We propose a system to rebroadcast the correction and integrity data via a data link as provided by the ground-based augmentation system such that aircraft equipped with a GPS landing system (GLS) can use the wide-area corrections and perform localizer performance with vertical guidance (LPV) approaches while maintaining the same level of integrity. In consequence, the system loses some availability and the time to alert is slightly increased. We build a prototype system and present data collected for one week, confirming technical feasibility. There is a loss of 5.3 percent of availability during a 1-week data collection cycle in which we compared our system to standalone LPV service. We tested our prototype with two commercially available GLS receivers with positive results and successfully demonstrated the functionality with a conventional Airbus 319 equipped with a standard GLS receiver.

    Regional climate downscaling over Europe: perspectives from the EURO-CORDEX community (2020)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-06-21
    Description: The European CORDEX (EURO-CORDEX) initiative is a large voluntary effort that seeks to advance regional climate and Earth system science in Europe. As part of the World Climate Research Programme (WCRP) - Coordinated Regional Downscaling Experiment (CORDEX), it shares the broader goals of providing a model evaluation and climate projection framework and improving communication with both the General Circulation Model (GCM) and climate data user communities. EURO-CORDEX oversees the design and coordination of ongoing ensembles of regional climate projections of unprecedented size and resolution (0.11° EUR-11 and 0.44° EUR-44 domains). Additionally, the inclusion of empirical-statistical downscaling allows investigation of much larger multi-model ensembles. These complementary approaches provide a foundation for scientific studies within the climate research community and others. The value of the EURO-CORDEX ensemble is shown via numerous peer-reviewed studies and its use in the development of climate services. Evaluations of the EUR-44 and EUR-11 ensembles also show the benefits of higher resolution. However, significant challenges remain. To further advance scientific understanding, two flagship pilot studies (FPS) were initiated. The first investigates local-regional phenomena at convection-permitting scales over central Europe and the Mediterranean in collaboration with the Med-CORDEX community. The second investigates the impacts of land cover changes on European climate across spatial and temporal scales. Over the coming years, the EURO-CORDEX community looks forward to closer collaboration with other communities, new advances, supporting international initiatives such as the IPCC reports, and continuing to provide the basis for research on regional climate impacts and adaptation in Europe.

    Late Oligocene—Early Miocene shortening in the Thrace Basin, northern Aegean (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-07-20
    Description: Late Cenozoic was a period of large-scale extension in the Aegean. The extension is mainly recorded in the metamorphic core complexes with little data from the sedimentary sequences. The exception is the Thrace Basin in the northern Aegean, which has a continuous record of Middle Eocene to Oligocene marine sedimentation. In the Thrace Basin, the Late Oligocene–Early Miocene was characterized by north-northwest (N25°W) shortening leading to the termination of sedimentation and formation of large-scale folds. We studied the stratigraphy and structure of one of these folds, the Korudağ anticline. The Korudağ anticline has formed in the uppermost Eocene–Lower Oligocene siliciclastic turbidites with Early Oligocene (31.6 Ma zircon U–Pb age) acidic tuff beds. The turbidites are underlain by a thin sequence of Upper Eocene pelagic limestone. The Korudağ anticline is an east-northeast (N65°E) trending fault-propagation fold, 9 km wide and 22 km long and with a subhorizontal fold axis. It is asymmetric with shallowly-dipping northern and steeply-dipping southern limbs. Its geometry indicates about 1 km of shortening in a N25°W direction. The folded strata are unconformably overlain by Middle Miocene continental sandstones, which constrain the age of folding. The Korudağ anticline and other large folds in the Thrace Basin predate the inception of the North Anatolian Fault (NAF) by at least 12 myr. The Late Oligocene–Early Miocene (28–17 Ma) shortening in the Thrace Basin and elsewhere in the Balkans forms an interlude between two extensional periods, and is probably linked to changes in the subduction dynamics along the Hellenic trench.

    The birth of the Alps: Ediacaran to Paleozoic accretionary processes and crustal growth along the northern Gondwana margin (2021)

    Details
    Publication Date: 2023-07-20
    Description: New whole-rock geochemical and coupled U–Pb and Lu–Hf LA-ICP-MS zircon data of metasedimentary rocks of the Austroalpine, South Alpine and Penninic basement domains are presented, to disentangle the pre-Variscan tectonic evolution of the proto-Alps. The studied units seem to record distinct stages of protracted Late Ediacaran to Carboniferous tectonosedimentary processes prior to the Variscan collision. In the case of Austroalpine and South Alpine units, nevertheless, no major differences in terms of provenance are observed, since most detrital zircon samples are characterized by a major Pan-African peak. Their detrital zircon spectra record a provenance from the northeastern Saharan Metacraton and the Sinai basement at the northern Arabian-Nubian Shield, being thus located along the eastern Early Paleozoic northern Gondwana margin, whereas sources located further west are inferred for the Penninic Unit, which might have been placed close to the Moldanubian Unit of the Bohemian Massif. In any case, it is thus clear that the Alpine basement remained in a close position to the Gondwana mainland at least during the Early Paleozoic. The Late Ediacaran to Silurian tectonic evolution, which includes Cadomian and Cenerian tectonometamorphic and magmatic processes, seem thus to record a continuum related to a retreating-mode accretionary orogen, with diachronous back-arc basin opening and possibly discrete compressional/transpressional pulses linked to changes in subduction zone dynamics. On the other hand, it is inferred that the Alpine basement essentially comprises Pan-African metasedimentary and subordinate metaigneous rocks, possibly with very few Early Neoproterozoic relics. This basement was significantly reworked during the protracted Paleozoic orogenic evolution, due to anatexis and/or assimilation by mantle-derived juvenile magmatism.

    Estimation of absolute GNSS satellite antenna group delay variations based on those of absolute receiver antenna group delays (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-07-20
    Description: GNSS satellite and receiving antennas exhibit group delay variations (GDV), which affect code pseudorange measurements. Like antenna phase center variations, which affect phase measurements, they are frequency-dependent and vary with the direction of the transmitted and received signal. GNSS code observations contain the combined contributions of satellite and receiver antennas. If absolute GDV are available for the receiver antennas, absolute satellite GDV can be determined. In 2019, an extensive set of absolute receiver antenna GDV was published and, thus, it became feasible to estimate absolute satellite antenna GDV based on terrestrial observations. We used the absolute GDV of four selected receiver antenna types and observation data of globally distributed reference stations that employ these antenna types to determine absolute GDV for the GPS, GLONASS, Galileo, BeiDou, and QZSS satellite antennas. Besides BeiDou-2 satellites whose GDV are known to reach up to 1.5 m peak-to-peak, the GPS satellites show the largest GDV at frequencies L1 and L5 with up to 0.3 and 0.4 m peak-to-peak, respectively. They also show the largest satellite-to-satellite variations within a constellation. The GDV of GLONASS-M satellites reach up to 25 cm at frequency G1; Galileo satellites exhibit the largest GDV at frequency E6 with up to 20 cm; BeiDou-3 satellites show the largest GDV of around 15 cm at frequencies B1-2 and B3. Frequencies L2 of GPS IIIA, E1 of Galileo FOC, and B2a/B2b of BeiDou-3 satellites are the least affected. Their variations are below 10 cm.

    Publication Date: 2023-07-27
    Description: Extensive morphological and age studies on more than 4600 detrital zircon grains recovered from modern sands of Namibia reveal complex mechanisms of sediment transport. These data are further supplemented by a zircon age database containing more than 100,000 single grain analyses from the entire southern Africa and allow for hypothesising of a large Southern Namibian Sediment Vortex located between the Damara Orogen and the Orange River in southern Namibia. The results of this study also allow assuming a modified model of the Orange River sand highway, whose origin is likely located further south than previously expected. Moreover, studied samples from other parts of Namibia give first insights into sediment movements towards the interior of the continent and highlight the potential impact of very little spatial variations of erosion rates. Finally, this study points out the huge potential of detrital zircon morphology and large geo-databases as an easy-to-use additional tool for provenance analysis.

    New constraints on the exhumation history of the western Tauern Window (European Alps) from thermochronology, thermokinematic modeling, and topographic analysis (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-07-27
    Description: The Brenner normal fault bounds the Tauern Window to the west and accommodated a significant portion of the orogen-parallel extension in the Eastern Alps. Here, we use zircon (U–Th)/He, apatite fission track, and apatite (U–Th)/He dating, thermokinematic modeling, and a topographic analysis to constrain the exhumation history of the western Tauern Window in the footwall of the Brenner fault. ZHe ages from an E–W profile (parallel to the slip direction of the fault) decrease westwards from ~ 11 to ~ 8 Ma and suggest a fault-slip rate of 3.9 ± 0.9 km/Myr, whereas AFT and AHe ages show no spatial trends. ZHe and AFT ages from an elevation profile indicate apparent exhumation rates of 1.1 ± 0.7 and 1.0 ± 1.3 km/Myr, respectively, whereas the AHe ages are again spatially invariant. Most of the thermochronological ages are well predicted by a thermokinematic model with a normal fault that slips at a rate of 4.2 km/Myr between ~ 19 and ~ 9 Ma and produces 35 ± 10 km of extension. The modeling reveals that the spatially invariant AHe ages are caused by heat advection due to faulting and posttectonic thermal relaxation. The enigmatic increase of K–Ar phengite and biotite ages towards the Brenner fault is caused by heat conduction from the hot footwall to the cooler hanging wall. Topographic profiles across an N–S valley in the fault footwall indicate 1000 ± 300 m of erosion after faulting ceased, which agrees with the results of our thermokinematic model. Valley incision explains why the Brenner fault is located on the western valley shoulder and not at the valley bottom. We conclude that the ability of thermokinematic models to quantify heat transfer by rock advection and conduction is crucial for interpreting cooling ages from extensional fault systems.

    Two-phase late Paleozoic magmatism (~ 313–312 and ~ 299–298 Ma) in the Lusatian Block and its relation to large scale NW striking fault zones: evidence from zircon U–Pb CA–ID–TIMS geochronology, bulk rock- and zircon chemistry (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-07-21
    Description: Late Paleozoic (Variscan) magmatism is widespread in Central Europe. The Lusatian Block is located in the NE Bohemian Massif and it is part of the Saxothuringian Zone of the Variscan orogen. It is bordered by two major NW-trending shear zones, the Intra-Sudetic Fault Zone towards NE and the Elbe Fault Zone towards SW. The scarce Variscan igneous rocks of the Lusatian Block are situated close to these faults. We investigated 19 samples from Variscan plutonic and volcanic rocks of the Lusatian Block, considering all petrological varieties (biotite-bearing granites from the Koenigshain and Stolpen plutons, amphibole-bearing granites from three boreholes, several volcanic dykes, and two volcanites from the intramontane Weissig basin). We applied whole-rock geochemistry (18 samples) and zircon evaporation dating (19 samples). From the evaporation data, we selected six representative samples for additional zircon SHRIMP and CA–ID–TIMS dating. For the Koenigshain pluton, possible protoliths were identified using whole-rock Nd-isotopes, and zircon Hf- and O-isotopes. The new age data allow a subdivision of Variscan igneous rocks in the Lusatian Block into two distinct magmatic episodes. The spatial relation of the two age groups to either the Elbe Fault Zone (298–299 Ma) or the Intra-Sudetic Fault Zone (312–313 Ma) together with reports on the fault-bound character of the dated intrusions suggests an interpretation as two major post-collisional faulting episodes. This assumption of two distinct magmatic periods is confirmed by a compilation of recently published zircon U–Pb CA–ID–TIMS data on further Variscan igneous rocks from the Saxothuringian Zone. New geochemical data allow us to exclude a dominant sedimentary protolith for the Koenigshain pluton as supposed by previous investigations. This conclusion is mainly based on new O- and Hf-isotope data on zircon and the scarcity of inherited zircons. Instead, acid or intermediate igneous rocks are supposed as the main source for these I-type granitoids from the Koenigshain pluton.

    Crop diversity effects on temporal agricultural production stability across European regions (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-07-29
    Description: Stabilizing agricultural production is fundamental to food security. At the national level, increasing the effective diversity of cultivated crops has been found to increase temporal production stability, i.e., the year-to-year stability of total caloric production of all crops combined. Here, we specifically investigated these effects at the regional level for the European Union and tested the effect of crop diversity in relation to agricultural inputs, soil properties, climate instability, and time on caloric, protein, and fat stability, as we hypothesized that the effect of diversity is context dependent. We further investigated these relationships for specific countries. We found that greater crop diversity was consistently associated with an increase in production stability, particularly in regions with large areas equipped for irrigation and low soil type diversity. For instance, in Spain and Italy, crop diversity showed the strongest positive effect among all predictors, while on the European level, the stabilizing effect of nitrogen use was substantially higher. In Germany, the crop diversity-stability relationship was weak, suggesting that crops react similarly to climatic, economic, and political factors or are grown in the same periods. With this study, we substantiate previous findings that crop diversity stabilizes agricultural caloric production and extend these with regard to protein and fat. The results elucidate the key drivers that enhance production stability for different European countries and regions, which is of key importance for a comparably productive agricultural region like Europe.

    Description: Dataset: Ehux growth rates for thermal response curve
    Description: This dataset presents growth rates for Emiliania huxleyi thermal response curve across 12 temperatures from 8.5-28.6C.Global warming will be combined with predicted increases in thermal variability in the future surface ocean, but how temperature dynamics will affect phytoplankton biology and biogeochemistry is largely unknown. Here, we examine the responses of the globally important marine coccolithophore Emiliania huxleyi to thermal variations at two frequencies (1 d and 2 d) at low (18.5 °C) and high (25.5 °C) mean temperatures. Elevated temperature and thermal variation decreased growth, calcification and physiological rates, both individually and interactively. The 1 d thermal variation frequencies were less inhibitory than 2 d variations under high temperatures, indicating that high-frequency thermal fluctuations may reduce heat-induced mortality and mitigate some impacts of extreme high-temperature events. Cellular elemental composition and calcification was significantly affected by both thermal variation treatments relative to each other and to the constant temperature controls. The negative effects of thermal variation on E. huxleyi growth rate and physiology are especially pronounced at high temperatures. These responses of the key marine calcifier E. huxleyi to warmer, more variable temperature regimes have potentially large implications for ocean productivity and marine biogeochemical cycles under a future changing climate.

    Description: Dataset: rocky intertidal biomimic
    Description: At a proximal level, the physiological impacts of global climate change on ectothermic organisms are manifest as changes in body temperatures. Especially for plants and animals exposed to direct solar radiation, body temperatures can be substantially different from air temperatures. We deployed biomimetic sensors that mimic the thermal characteristics of intertidal mussels at 66 sites worldwide, from 1998-present. Loggers recorded temperatures at 10-15 minute intervals nearly continuously at multiple intertidal elevations. Comparisons against direct measurements of mussel tissue temperature suggest errors of ~2.0-2.5°C, during daily fluctuations that often exceed 15°-20°C. Geographic patterns in thermal stress based on biomimetic logger measurements were generally far more complex than anticipated based only on “habitat” level measurements, and show that animals are reaching temperatures far above air temperature on sunny days. This unique data set provides a means of assessing spatial and temporal variability in intertidal thermal stress, and links physiological measurements to field patterns.

    Description: Dataset: Ehux physiology under thermal variation
    Description: Intracellular elemental quotas under low and high temperatures for E. huxleyi in constant and fluctuating thermal environments. This dataset includes the growth rates under low and high temperatures for E. huxleyi in constant and fluctuating thermal environments. Global warming will be combined with predicted increases in thermal variability in the future surface ocean, but how temperature dynamics will affect phytoplankton biology and biogeochemistry is largely unknown. Here, we examine the responses of the globally important marine coccolithophore Emiliania huxleyi to thermal variations at two frequencies (1 d and 2 d) at low (18.5 °C) and high (25.5 °C) mean temperatures. Elevated temperature and thermal variation decreased growth, calcification and physiological rates, both individually and interactively. The 1 d thermal variation frequencies were less inhibitory than 2 d variations under high temperatures, indicating that high-frequency thermal fluctuations may reduce heat-induced mortality and mitigate some impacts of extreme high-temperature events. Cellular elemental composition and calcification was significantly affected by both thermal variation treatments relative to each other and to the constant temperature controls. The negative effects of thermal variation on E. huxleyi growth rate and physiology are especially pronounced at high temperatures. These responses of the key marine calcifier E. huxleyi to warmer, more variable temperature regimes have potentially large implications for ocean productivity and marine biogeochemical cycles under a future changing climate.

    Series 5: pCO2 as one of multiple stressors for Thalassiosira weissflogii (2015)

    Details
    Publication Date: 2022-05-26
    Description: The presented data suggest that acclimatization times of exponentially growing diatoms to environmental perturbations may be weeks to months, rather than days to weeks. The response of acclimatized T. weissflogii to pCO2 depended on irradiance and temperature and was highly interactive, non-linear, and non-uniform. A very significant negative effect of pCO2 was observed under growth conditions that were light-, and temperature-limited; a smaller, but still significant negative response was seen under light-limiting growth conditions, whereas pCO2 did not affect growth rates of T. weissflogii under light-saturated growth conditions. Cell quotas of organic carbon, nitrogen, or chlorophyll a were linked to growth rate. The cell-normalized production of transparent exopolymer particles (TEP) was positively correlated with POC cell quotas, with some minor impact of irradiance and pCO2 on the relationship. This correlation of TEP production with carbon cell quotas is consistent with the hypothesis that extracellular release is an inherent component of cell metabolism. Results suggest that elevated pCO2 functions as an (additional) metabolic stressor for T. weissflogii and that the interaction of different stressors determines growth rates and cell characteristics in a complex, non-linear relationship.
    Description: The increase in partial pressure of CO2 (pCO2) is causing ocean acidification, which impacts the growth rates and elemental composition of phytoplankton. Here, shifts in growth rates and cell quotas of Thalassiosira weissflogii grown under a variety of different temperatures, irradiances, and pCO2 conditions are discussed.

    Series 4: Aggregation of Thalassiosira weissflogii as a function of pCO2, temperature and bacteria (2014)
    Biological and Chemical Oceanography Data Management Office (BCO-DMO). Contact: bco-dmo-data@whoi.edu
    Details
    Publication Date: 2022-05-26
    Description: The Series 4 Experiment, Aggregation of Thalassiosira weissflogii as a function of pCO2, temperature and bacteria, is made up of 2 phases. The Acclimatisation Phase and the Aggregation Phase. The Acclimatisation Phase has two components – The Carbonate System data and the Cell Counts Data. The Aggregation Phase also has two components – The Carbonate System + TEP data and the Sinking Velocity data. Note: For a complete list of measurements, refer to the supplemental document ' Series4_Field_names.pdf' .
    Description: Increasing Transparent Exopolymer Particle (TEP) formation during diatom blooms as a result of elevated temperature and pCO2 have been suggested to result in enhanced aggregation and carbon flux, therewith potentially increasing the sequestration of carbon by the ocean. We present experimental results on TEP and aggregate formation by Thalassiosira weissflogii (diatom) in the presence or absence of bacteria under two temperature and three pCO2 scenarios. During the aggregation phase of the experiment TEP formation was elevated at the higher temperature (20ºC vs. 15ºC), as predicted. However, in contrast to expectations based on the established relationship between TEP and aggregation, aggregation rates and sinking velocity of aggregates were depressed in warmer treatments, especially under ocean acidification conditions. If our experimental findings can be extrapolated to natural conditions, they would imply a reduction in carbon flux and potentially reduced carbon sequestration after diatoms blooms in the future ocean.

    Geological development of the Limpopo Shelf (southern Mozambique) during the last sealevel cycle (2020)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-06-17
    Description: Paleo-shorelines on continental shelves give insights into the complex development of coastlines during sealevel cycles. This study investigates the geologic development of the Limpopo Shelf during the last sealevel cycle using multichannel seismic and acoustic datasets acquired on the shelf in front of the Limpopo River mouth. A detailed investigation of seismic facies, shelf bathymetry, and a correlation to sea level revealed the presence of numerous submerged shorelines on the shelf. These shorelines are characterized by distinct topographic ridges and are interpreted as coastal dune ridges that formed in periods of intermittent sealevel still-/slowstand during transgression. The shorelines are preserved due to periods of rapid sealevel rise (melt water pulses) that led to the overstepping of the dune ridges as well as due to early cementation of accumulated sediments that increased the erosive resistance of the ridges. The high along-shelf variability of the submerged dune ridges is interpreted as a result of pre-existing topography affecting shoreline positions during transgression. The pre-existing topography is controlled by the underlying sedimentary deposits that are linked to varying fluvial sediment input at different points on the shelf. The numerous prominent submerged dune ridges form barriers for the modern fluvial sediment from the Limpopo River and dam sediment on the inner shelf. They may also facilitate along-shelf current-induced sediment transport.

    Slab break-offs in the Alpine subduction zone (2020)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-06-17
    Description: After the onset of plate collision in the Alps, at 32–34 Ma, the deep structure of the orogen is inferred to have changed dramatically: European plate break-offs in various places of the Alpine arc, as well as a possible reversal of subduction polarity in the eastern Alps have been proposed. We review different high-resolution tomographic studies of the upper mantle and combine shear- and body-wave models to assess the most reliable geometries of the slabs. Several hypotheses for the tectonic evolution are presented and tested against the tomographic model interpretations and constraints from geologic and geodetic observations. We favor the interpretation of a recent European slab break-off under the western Alps. In the eastern Alps, we review three published scenarios for the subduction structure and propose a fourth one to reconcile the results from tomography and geology. We suggest that the fast slab anomalies are mainly due to European subduction; Adriatic subduction plays no or only a minor role along the Tauern window sections, possibly increasing towards the Dinarides. The apparent northward dip of the slab under the eastern Alps may be caused by imaging a combination of Adriatic slab, from the Dinaric subduction system, and a deeper lying European one, as well as by an overturned, retreating European slab.

    Mesozoic deposits of SW Gondwana (Namibia): unravelling Gondwanan sedimentary dispersion drivers by detrital zircon (2020)
    Zieger, J. ; Harazim, S. ; Hofmann, M. ; [et al.]
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-06-17
    Description: The Namibian Mesozoic successions may be remnant of a high dynamic sedimentary system that is characterized by multiple stages of sediment accumulation and erosion with contemporaneous homogenization starting with the deposition of the Permo-Carboniferous Dwyka Group strata and continues at least until the Lower Cretaceous. The Lower Cretaceous sedimentary system is interpreted to have involved at least an area covering the whole SW Gondwana, documenting the sedimentary history during the evolution from an ice house environment to an arid desert. To test the sediment homogenization hypothesis, we applied a combination of isotopic and morphometric data on detrital zircon grains, as well as whole-rock geochemical data of selected Mesozoic sandstones from Namibia. As a base for the interpretation of the detrital zircon age data we compiled a zircon age dataset with c. 44,000 analyses for the southern African region. All samples reveal a major detrital pan-African zircon age peak of c. 0.5–0.7 Ga sourced from the pan-African magmatic events occurring around the Kalahari Craton margin. The lowermost Triassic is characterized by the occurrence of additional Mesoproterozoic and Paleoproterozoic age peaks of c. 1.0–1.2 Ga and 1.8–2.0 Ga with a majority of zircon grains showing angular shapes. The protosource of these grains is interpreted to possibly be the Namaqua Metamorphic Complex and other Paleoproterozoic structural units deformed in course of the Namaqua orogeny. In contrast, other samples show a prominent Permo-Triassic age peak and completely rounded zircon grains, putatively derived from within the Gondwanides volcanic arc. The disparity in the zircon age pattern may point towards a change in provenance and also a change in the whole system of zircon recycling during the Mesozoic southern Gondwana. The Lower Triassic Neu Loore fm. are constrained to more local bedrock sources and short zircon transport distance. In contrast, zircon grains of the Middle Triassic Omingonde, the Jurassic Etjo und the Cretaceous Twyfelfontein formations are an expression for a major recycling and sediment homogenization system. The system was facilitated by an interplay between fluvial and eolian sedimentary transport systems.

    On the possibility of getting traceable time and frequency measurements via GNSS receivers (2020)
    Springer Berlin Heidelberg

    Publication Date: 2023-06-16
    Description: The realization of Coordinated Universal Time, one of the tasks of the International Bureau of Weights and Measures, relies on a network of international time links which currently is organized in a star-like scheme that links all contributing laboratories. GPS signal reception is the technique most widely employed by the laboratories. The PTB currently plays a unique role in the process due to its function as the central pivot in the time transfer between the participating laboratories. We discuss how the PTB meets its obligations to the international timekeeping community as well as to its users in Germany. In its role as an National Metrology Institute (NMI), PTB is entrusted with the realization and dissemination of legal time in Germany. The services were offered to the public support measurements and timing applications traceable to the national and international standards to be made in calibration laboratories and in many industrial sectors. We thus discuss the meaning and definition of traceability, how different GNSS systems can be used to establish traceability and their performance in doing so.

    Sentinel-6A precise orbit determination using a combined GPS/Galileo receiver (2021)
    Springer Berlin Heidelberg
    Details
    Publication Date: 2023-06-22
    Description: The Sentinel-6 (or Jason-CS) altimetry mission provides a long-term extension of the Topex and Jason-1/2/3 missions for ocean surface topography monitoring. Analysis of altimeter data relies on highly-accurate knowledge of the orbital position and requires radial RMS orbit errors of less than 1.5 cm. For precise orbit determination (POD), the Sentinel-6A spacecraft is equipped with a dual-constellation GNSS receiver. We present the results of Sentinel-6A POD solutions for the first 6 months since launch and demonstrate a 1-cm consistency of ambiguity-fixed GPS-only and Galileo-only solutions with the dual-constellation product. A similar performance (1.3 cm 3D RMS) is achieved in the comparison of kinematic and reduced-dynamic orbits. While Galileo measurements exhibit 30–50% smaller RMS errors than those of GPS, the POD benefits most from the availability of an increased number of satellites in the combined dual-frequency solution. Considering obvious uncertainties in the pre-mission calibration of the GNSS receiver antenna, an independent inflight calibration of the phase centers for GPS and Galileo signal frequencies is required. As such, Galileo observations cannot provide independent scale information and the estimated orbital height is ultimately driven by the employed forces models and knowledge of the center-of-mass location within the spacecraft. Using satellite laser ranging (SLR) from selected high-performance stations, a better than 1 cm RMS consistency of SLR normal points with the GNSS-based orbits is obtained, which further improves to 6 mm RMS when adjusting site-specific corrections to station positions and ranging biases. For the radial orbit component, a bias of less than 1 mm is found from the SLR analysis relative to the mean height of 13 high-performance SLR stations. Overall, the reduced-dynamic orbit determination based on GPS and Galileo tracking is considered to readily meet the altimetry-related Sentinel-6 mission needs for RMS height errors of less than 1.5 cm.

    Auswirkungen des Klimawandels auf das Grundwasser und die Wasserversorgung in Süddeutschland (2021)
    Springer Berlin Heidelberg

    Publication Date: 2023-08-17
    Description: Für die öffentliche Trinkwasserversorgung in Süddeutschland wird größtenteils Grund- und Quellwasser genutzt. Der Kenntnis über die Entwicklung des Bodenwasserhaushalts und insbesondere der Grundwasserneubildung kommt somit eine große Bedeutung zu. Im Rahmen der Kooperation KLIWA (Klimaveränderung und Konsequenzen für die Wasserwirtschaft, www.kliwa.de) wurde die Entwicklung des Bodenwasserhaushaltes und der Grundwasserneubildung aus Niederschlag für den Zeitraum von 1951 bis 2019 für die Länder Baden-Württemberg, Bayern, Hessen und Rheinland-Pfalz mit dem Bodenwasserhaushaltmodell GWN-BW modelliert. Seit Ende der 1980er-Jahre zeigt sich ein Anstieg der mittleren jährlichen Temperatur in Süddeutschland. Die jährlichen Niederschlagssummen haben sich in der jüngeren Vergangenheit (seit 2003) reduziert und somit eine deutliche Verringerung der Grundwasserneubildung aus Niederschlag bewirkt. Gleichzeitig ist eine Zunahme des Trockenheitsindex (Anzahl an Tagen mit Füllung des Bodenwasserspeichers 〈 30 % der nutzbaren Feldkapazität) zu erkennen. Häufiger werdende und länger anhaltende Trockenperioden stellen auch die Wasserwirtschaft zunehmend vor Herausforderungen und bedürfen der frühzeitigen Entwicklung von Handlungsoptionen, z. B. auf der Basis des hier vorgestellten „Trockenwetterdargebots“, um Nutzungskonflikte zu entschärfen.
