    Uncovering deformation processes from surface displacements (2016)
    Elsevier
    Details
    Publication Date: 2021-05-12
    Description: Today, satellite remote sensing has reached a key role in Earth Sciences. In particular, Synthetic ApertureRadar (SAR) sensors and SAR Interferometry (InSAR) techniques are widely used for the study of dynamicprocesses occurring inside our living planet. Over the past 3 decades, InSAR has been applied for mappingtopography and deformation at the Earth’s surface. These maps are widely used in tectonics, seismology,geomorphology, and volcanology, in order to investigate the kinematics and dynamics of crustal faulting,the causes of postseismic and interseismic displacements, the dynamics of gravity driven slope failures,and the deformation associated with subsurface movement of water, hydrocarbons or magmatic fluids.

    Emerging trends in the sea state of the Beaufort and Chukchi seas (2016)
    Elsevier
    Details
    Publication Date: 2022-05-26
    Description: © The Author(s), 2016. This article is distributed under the terms of the Creative Commons Attribution License. The definitive version was published in Ocean Modelling 105 (2016): 1-12, doi:10.1016/j.ocemod.2016.02.009
    Description: The sea state of the Beaufort and Chukchi seas is controlled by the wind forcing and the amount of ice-free water available to generate surface waves. Clear trends in the annual duration of the open water season and in the extent of the seasonal sea ice minimum suggest that the sea state should be increasing, independent of changes in the wind forcing. Wave model hindcasts from four selected years spanning recent conditions are consistent with this expectation. In particular, larger waves are more common in years with less summer sea ice and/or a longer open water season, and peak wave periods are generally longer. The increase in wave energy may affect both the coastal zones and the remaining summer ice pack, as well as delay the autumn ice-edge advance. However, trends in the amount of wave energy impinging on the ice-edge are inconclusive, and the associated processes, especially in the autumn period of new ice formation, have yet to be well-described by in situ observations. There is an implicit trend and evidence for increasing wave energy along the coast of northern Alaska, and this coastal signal is corroborated by satellite altimeter estimates of wave energy.

    The multi-sensory approach as a geoeducational strategy (2015)
    Copernicus Publications
    Details
    Publication Date: 2017-04-04
    Description: Geoscience knowledge has a strong impact in modern society as it relates to natural hazards, sustainability and environmental issues. The general public has a demanding attitude towards the understanding of crucial geo-scientific topics that is only partly satisfied by science communication strategies and/or by outreach or school programs. A proper knowledge of the phenomena might help trigger crucial inquiries when approaching mitigation of geohazards and geo-resources, while providing the right tool for the understanding of news and ideas floating from the web or other media, and, in other words, help communication to be more efficient. Nonetheless available educational resources seem to be inadequate in meeting the goal, while research institutions are facing the challenge to experience new communication strategies and non-conventional way of learning capable to allow the understanding of crucial scientific contents. We suggest the use of multi-sensory approach as a successful non-conventional way of learning for children and as a different perspective of learning for older students and adults. Sense organs stimulation are perceived and processed to build the knowledge of the surrounding, including all sorts of hazards. Powerfully relying in the sense of sight, Humans have somehow lost most of their ability for a deep perception of the environment enriched by all the other senses. Since hazards involve emotions we argue that new ways to approach the learning might go exactly through emotions that one might stress with a tactile experience, a hearing or smell stimulation. To test and support our idea we are building a package of learning activities and exhibits based on a multi-sensory experience where the sight is not allowed.

    Natural hazards revealed to children: the other side of prevention (2015)
    Geological Society, London
    Details
    Publication Date: 2017-04-04
    Description: Risk misperception often ineffectively drives us to choose recovery over prevention; the latter being usually conceived with actions aimed at mitigation of infrastructure vulnerability. Although it is fundamental to implant the culture of prevention and therefore have an impact on risk mitigation and community disaster resilience, long-term programmes encompassing knowledge, innovation and education are often underestimated. If education involves children, we more efficiently spread the culture of risk reduction through a chain reaction dissemination mechanism and prompt behaviours that are better imprinted on the mind, reinforce awareness of hazard response, and foster citizens who tomorrow might be part of the process of making crucial decisions on prevention strategies. For the past 10 years, our learn-by-playing, hands-on, emotionaldriven, curiosity-driven approach activities have involved more than 20 000 students and teachers living in areas prone to natural hazards. In addition to requests and appreciation from the public, questionnaires handed out to teachers and students have proved that our approach to prevention best practice is successful. Questionnaires filled in by children and their families encouraged us to promote the strong potential for dissemination in the local environment. We are engaged in on-going research on risk reduction oriented science outreach activities to implement models focused on geoscience education and to give citizens tools to affect the process of risk reduction decision-making.

    Seismic damage to pipelines in the framework of Na-Tech risk assessment (2015)
    Elsevier
    Details
    Publication Date: 2020-05-29
    Description: The structural integrity of pipelines undergone seismic waves is crucial for industrial installation and for the distributed transportation networks of gaseous and liquid fluids. However, it is nowadays proved that the definition of seismic vulnerability based on purely, structural-derived limit states or on return-to-service or even on the purely economic repair rate indications, is not sufficient for the holistic analysis of risks. On the other hand, detailed numerical studies based on full analyses (including fluid/soil/structure interaction) are too expensive for the aims of risk assessment and simplified methodologies are still needed.In this paper, a large database of earthquake-induced damage for steel and non-steel pipelines is presented. Each case was analyzed and collected from post-earthquake reconnaissance, seismic engineering reports and technical papers. The database may be adopted for the definition of specific vulnerability function (fragility curves), which are commonly implemented in multi-hazard analyses, and more in general for the assessment of Na-Tech risks (Natural events triggering Technological disasters). Seismic damage to pipelines in the framework of Na-Tech risk assessment.

    The influence of sea ice and snow cover and nutrient availability on the formation of massive under-ice phytoplankton blooms in the Chukchi Sea (2015)
    Elsevier
    Details
    Publication Date: 2022-05-25
    Description: © The Author(s), 2015. This article is distributed under the terms of the Creative Commons Attribution License. The definitive version was published in Deep Sea Research Part II: Topical Studies in Oceanography 118 (2015): 122-135, doi:10.1016/j.dsr2.2015.02.008.
    Description: A coupled biophysical model is used to examine the impact of changes in sea ice and snow cover and nutrient availability on the formation of massive under-ice phytoplankton blooms (MUPBs) in the Chukchi Sea of the Arctic Ocean over the period 1988–2013. The model is able to reproduce the basic features of the ICESCAPE (Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment) observed MUPB during July 2011. The simulated MUPBs occur every year during 1988–2013, mainly in between mid-June and mid-July. While the simulated under-ice blooms of moderate magnitude are widespread in the Chukchi Sea, MUPBs are less so. On average, the area fraction of MUPBs in the ice-covered areas of the Chukchi Sea during June and July is about 8%, which has been increasing at a rate of 2% yr–1 over 1988–2013. The simulated increase in the area fraction as well as primary productivity and chlorophyll a biomass is linked to an increase in light availability, in response to a decrease in sea ice and snow cover, and an increase in nutrient availability in the upper 100 m of the ocean, in conjunction with an intensification of ocean circulation. Simulated MUPBs are temporally sporadic and spatially patchy because of strong spatiotemporal variations of light and nutrient availability. However, as observed during ICESCAPE, there is a high likelihood that MUPBs may form at the shelf break, where the model simulates enhanced nutrient concentration that is seldom depleted between mid-June and mid-July because of generally robust shelf-break upwelling and other dynamic ocean processes. The occurrence of MUPBs at the shelf break is more frequent in the past decade than in the earlier period because of elevated light availability there. It may be even more frequent in the future if the sea ice and snow cover continues to decline such that light is more available at the shelf break to further boost the formation of MUPBs there.

    Detection and quantification of oil under sea ice : the view from below (2015)
    Elsevier
    Details
    Publication Date: 2022-05-25
    Description: © The Author(s), 2014. This article is distributed under the terms of the Creative Commons Attribution License. The definitive version was published in Cold Regions Science and Technology 109 (2015): 9-17, doi:10.1016/j.coldregions.2014.08.004.
    Description: Traditional measures for detecting oil spills in the open-ocean are both difficult to apply and less effective in ice-covered seas. In view of the increasing levels of commercial activity in the Arctic, there is a growing gap between the potential need to respond to an oil spill in Arctic ice-covered waters and the capability to do so. In particular, there is no robust operational capability to remotely locate oil spilt under or encapsulated within sea ice. To date, most research approaches the problem from on or above the sea ice, and thus they suffer from the need to ‘see’ through the ice and overlying snow. Here we present results from a large-scale tank experiment which demonstrate the detection of oil beneath sea ice, and the quantification of the oil layer thickness is achievable through the combined use of an upward-looking camera and sonar deployed in the water column below a covering of sea ice. This approach using acoustic and visible measurements from below is simple and effective, and potentially transformative with respect to the operational response to oil spills in the Arctic marine environment. These results open up a new direction of research into oil detection in ice-covered seas, as well as describing a new and important role for underwater vehicles as platforms for oil-detecting sensors under Arctic sea ice.
    Description: This work was funded through a competitive grant for the detection of oil under ice obtained from Prince William Sound Oil Spill Recovery Institute (OSRI) (11-10-09). Additional funding/resources was obtained through the EU FP7 funded ACCESS programme (Grant Agreement n°. 265863).
