    Sedimentation and mineral analysis on sediment cores from the Lena Delta (2002)
    PANGAEA
    In:  Supplement to: Schwamborn, Georg; Rachold, Volker; Grigoriev, Mikhail N (2002): Late Quaternary Sedimentation History of the Lena Delta. Quaternary International, 89(1), 119-134, https://doi.org/10.1016/S1040-6182(01)00084-2

    Description: Core and outcrop analysis from Lena mouth deposits have been used to reconstruct the Late Quaternary sedimentation history of the Lena Delta. Sediment properties (heavy mineral composition, grain size characteristics, organic carbon content) and age determinations (14C AMS and IR-OSL) are applied to discriminate the main sedimentary units of the three major geomorphic terraces, which form the delta. The development of the terraces is controlled by complex interactions among the following four factors: (1) Channel migration. According to the distribution of 14C and IR-OSL age determinations of Lena mouth sediments, the major river runoff direction shifted from the west during marine isotope stages 5-3 (third terrace deposits) towards the northwest during marine isotope stage 2 and transition to stage 1 (second terrace), to the northeast and east during the Holocene (first terrace deposits). (2) Eustasy. Sea level rise from Last Glacial lowstand to the modern sea level position, reached at 6-5 ka BP, resulted in back-filling and flooding of the palaeovalleys. (3) Neotectonics. The extension of the Arctic Mid-Ocean Ridge into the Laptev Sea shelf acted as a halfgraben, showing dilatation movements with different subsidence rates. From the continent side, differential neotectonics with uplift and transpression in the Siberian coast ridges are active. Both likely have influenced river behavior by providing sites for preservation, with uplift, in particular, allowing accumulation of deposits in the second terrace in the western sector. The actual delta setting comprises only the eastern sector of the Lena Delta. (4) Peat formation. Polygenetic formation of ice-rich peaty sand (''Ice Complex'') was most extensive (7-11 m in thickness) in the southern part of the delta area between 43 and 14 ka BP (third terrace deposits). In recent times, alluvial peat (5-6 m in thickness) is accumulated on top of the deltaic sequences in the eastern sector (first terrace).

    Pollen record and age determination of profile CS98-10 at Cape Shpindler, Yugorski Peninsula, northwest Russia (2001)

    In:  Supplement to: Andreev, Andrei A; Manley, William F; Ingólfsson, Ólafur; Forman, Steven L (2001): Environmental changes on Yugorski Peninsula, Kara Sea, Russia, during the last 12,800 radiocarbon years.

    Description: New pollen and radiocarbon data from an 8.6-m coastal section, Cape Shpindler (69°43' N; 62°48' E), Yugorski Peninsula, document the latest Pleistocene and Holocene environmental history of this low Arctic region. Twelve AMS 14C dates indicate that the deposits accumulated since about 13,000 until 2000 radiocarbon years BP. A thermokarst lake formed ca. 13,000-12,800 years BP, when scarce arctic tundra vegetation dominated the area. By 12,500 years BP, a shallow lake existed at the site, and Arctic tundra with Poaceae, Cyperaceae, Salix, Saxifraga, and Artemisia dominated nearby vegetation. Climate was colder than today. Betula nana became dominant during the Early Preboreal period about 9500 years BP, responding to a warm event, which was one of the warmest during the Holocene. Decline in B. nana and Salix after 9500 years BP reflects a brief event of Preboreal cooling. A subsequent increase in Betula and Alnus fruticosa pollen percentages reflects amelioration of environmental conditions at the end of Preboreal period (ca. 9300 years BP). A decline in arboreal taxa later, with a dramatic increase in herb taxa, reflects a short cold event at about 9200 years BP. The pollen data reflect a northward movement of tree birch, peaking at the middle Boreal period, around 8500 years BP. Open Betula forest existed on the Kara Sea coast of the Yugorski Peninsula during the Atlantic period (8000-4500 years BP), indicating that climate was significantly warmer than today. Deteriorating climate around the Atlantic-Subboreal boundary (ca. 4500 years BP) is recorded by a decline in Betula percentages. Sedimentation slowed at the site, and processes of denudation and/or soil formation started at the beginning of the Subatlantic period, when vegetation cover on Yugorski Peninsula shifted to near-modern assemblages.

    Late Quaternary sedimentation in Kejser Franz Joseph Fjord and the continental margin of East Greenland (2002)
    PANGAEA
    In:  Supplement to: Evans, Jeff; Dowdeswell, Julian A; Grobe, Hannes; Niessen, Frank; Stein, Ruediger; Hubberten, Hans-Wolfgang; Whittington, R J (2002): Late Quaternary sedimentation in Kejser Franz Joseph Fjord and the continental margin of East Greenland. Geological Society of London, Special Publications (Open Acess http://hdl.handle.net/10013/epic.15709.d008), 203, 149-179, https://doi.org/10.1144/GSL.SP.2002.203.01.09
    Details
    Publication Date: 2024-07-03
    Description: The marine sedimentary record in Kejser Franz Joseph Fjord and on the East Greenland continental margin contains a history of Late Quaternary glaciation and sedimentation. Evidence suggests that a middle-shelf moraine represents the maximum shelfward extent of the Greenland Ice Sheet during the last glacial maximum. On the upper slope, coarse-grained sediments are derived from the release of significant quantities of iceberg-rafted debris (IRD) and subsequent remobilization by subaqueous mass-flows. The middle-lower slope is characterized by hemipelagic sedimentation with lower quantities of IRD (dropstone mud and sandy mud), punctuated episodically by deposition of diamicton and graded sand/gravel facies by subaqueous debris flows and turbidity currents derived from the mass failure of upper slope sediments. The downslope decrease of IRD reflects either the action of the East Greenland Current (EGC) confining icebergs to the upper slope, or to the more ice-proximal setting of the upper slope relative to the LGM ice margin. Sediment gravity flows on the slope are likely to have fed into the East Greenland channel system, contributing to its formation in conjunction with the cascade of dense brines down the slope following sea-ice formation across the shelf. Deglaciation commenced after 15,300 14C years, as indicated by meltwater-derived light oxygen isotope ratios. An abrupt decrease in both IRD deposition and delivery of coarse-grained debris to the slope at this time supports ice recession, with icebergs confined to the shelf by the EGC. Glacier ice had abandoned the middle shelf before 13,000 14C years with ice loss through iceberg calving and deposition of diamicton. Continued retreat of glacier-ice from the inner shelf and through the fjord is marked by a transition from subglacial till/bedrock in acoustic records, to ice-proximal meltwater-derived laminated mud to ice-distal bioturbated mud. Ice abandoned the inner shelf before 9100 14C years and probably stabilized in Fosters Bugt at 10,000 14C years. Distinct oxygen isotope minima on the inner shelf indicate meltwater production during ice retreat. The outer fjord was free of ice before 7440 14C years. Glacier retreat through the mid-outer fjord was punctuated by topographically-controlled stillstands where ice-proximal sediment was fed into fjord basins. The dominance of fine-grained, commonly laminated facies during deglaciation supports ablation-controlled, ice-mass loss. Glacimarine sedimentation within the Holocene middle-outer fjord system is dominated by sediment gravity flow and suspension settling from meltwater plumes. Suspension sediments comprise mainly mud facies indicating significant meltwater-deposition that overwhelms debris release from icebergs in this East Greenland fjord system. The relatively widespread occurrence of fine-grained lithofacies in East Greenland fjords suggests that meltwater sedimentation can be significant in polar glacimarine environments. The ice-distal continental margin is characterized by meltwater sedimentation in the inner shelf deep, iceberg scouring over shallow shelf regions, winnowing and erosion by the East Greenland Current on the middle-outer shelf, and hemipelagic sedimentation on the continental slope.

    Description: Continental flood basalt (CFB) volcanism is hypothesized to have played a causative role in global climate change and mass extinctions. Uncertainties associated with radiometric dating preclude a clear chronological assessment of the environmental consequences of CFB volcanism. Our results document a 25% decline in the marine 187Os/188Os record that predates the Cretaceous-Tertiary boundary (KTB) and coincides with late Maastrichtian warming. We argue that this decline provides a chemostratigraphic marker of Deccan volcanism and thus constitutes compelling evidence that the main environmental consequence of Deccan volcanism was a transient global warming event of 3° to 5°C that is fully resolved from the KTB mass extinction.

Starting from the question for the dominant epibenthic prey and the intensity of predation pressure in seagrass habitats, we investigated a seegrasbed in the Sylt- Rømø bight. in sommer 2003. A predator enclosure experiment has been carried out in artificial tide pools of similar size, and a bait experiment were carried out in the surrounding seagrass bed. The most frequent epibenthic organisms within the intertidal seagrass beds consist of four dominant species: The brown shirmp (Crangon crangon, Linnaeus), the sand goby (Pomatoschitus microps, Krøyer), the isopode (Idotea balthica, Pallas) and the shore crab (Carcinus maenas, Linnaeus.). C. crangon showed an average annual abundance during high water of approximately 80 animals per m-2 (P.POL TE pers. Com.). Pomatoschistus microps and Carcinus maenas showed an average annual abundance of 7 animals m 2 and of 195 animals m-2. An abundance of 26 individuals m-2 was found for I. balthica (P.POLTE pers. Com.). As shown for the seagrass bed, C.crangon, P.microps and C.maenas were also the dominant forms in the tide pools. I. balthica could be found with 26 individuals m-2. The abundance of C. crangon were measured with an Annual average of 157 animals m-2 and therefore showed different results for the seagrassbeds. P. microps and C. maenas showed an average annual abundance of 15 animals m-2 and of 22 animals m-2 respectively. Mobile fauna migrates with the ebb tide into deeper waters (e.g. Pomatoschistus microps.) The substantially lower results of C. maenas within tide pools compared to adjacent seagrass beds can be partly explained by sampling time. In the seagrasbed sampling started earlier in the year (of May), and included the larval and juvenile stages of C. maenas. This led to a substantially higher abundance. Low abundance of I. balthica can be explained by its requirement for a structured habitat. I. balthica needs branched algal structures as a firm substrat. Such structures were hardly available in the tide pools...

    Growth and macronutritional requirements of signal crayfish Pacifastacus leniusculus (Dana) in aquaculture (2004)
    Details
    Publication Date: 2024-07-01
    Description: In Europe, increased attempts to intensify crayfish aquaculture have been carried out in recent years. Some of the major problems arising from the intensification are related to dietary supply of the animals in culture ponds and tanks. This study therefore focussed on some of the key objectives supporting the development of suitable diets for signal crayfish Pacifastacus leniusculus aquaculture. A large-scale response surface experiment was carried out to study the influences of different macronutrients (protein, lipid, carbohydrate) on crayfish growth and body composition. The results from this experiment led to the development of an improved experimental diet containing high levels of protein and carbohydrates, while increased lipid concentrations seemed to be influencing growth adversely. Further experiments were carried out to improve diet quality. For this purpose, diet types and the suitability of different binding agents were investigated. A small experiment was carried out to monitor the effects of attractants on growth of juvenile signal crayfish. A second objective of this study was the establishment of a new method to measure physiological responses of crayfish to different treatments. Running mid-term or long term experiments require high amounts of resources and slow down the process of dietary development. The measurement of RNA/DNA ratio has proven to be a suitable instrument to examine short-term metabolic responses to different key factors such as feeding regime, diet quality and digestibility and bioavailability of essential nutrients. The study has stressed the importance of proper diet preparation and composition for successful astaciculture. Binding agents were found to have major influence on diet digestibility and bioavailability of macronutrients. As another result of this study, further experiments are regarded to be necessary to examine the response of signal crayfish to different levels of lipid and protein in their diet. Some of the results obtained suggest a lack of regulatory capacity regarding the animals’ protein/lipid ratio. Further experiments however will have to be carried out to proof this hypothesis.

    Zonale Energieflüsse über dem Nordatlantik (2004)
    Details
    Publication Date: 2024-07-01
    Description: In this study the mean tropospherical total zonal energy fluxes based on the NCEPNCAR reanalyses data are calculated for the time period 1948-2003. The interannual wintertime variability and the vertical structure of the fluxes are analysed. Since the dominant mode of atmospheric variability, the North Atlantic Oscillation, modulates the mean zonal current over the northern Atlantic region on monthly timescales, the NAO is expected to be the main cause for the interannual variability of energy fluxes. This study aims to analyse the linkage between this variabilty of zonal energy fluxes and the NAO. If the interannual variability of zonal energy transport directed to the european continent is associated with the NAO, the interannual energy flux variability can be referred to the variability of atmospheric circulation. In the first section, a climatology shows the three-dimensional structure of the mean zonal energy fluxes and its interannual seasonal standard deviations. In the second section, the dominant patterns of variability in various cross-sections parallel to the circles of longitude are obtained by EOF-analysis. The two leading EOF-patterns show barotropic structures, which in general agree in all sections. The 1.EOF explains more than 50% of the variance, the 2.EOF 25%. There exists however a significant correlation between the principle components only of the first EOFs of the western and eastern cross sections. The connection between zonal fl ux anomalies and the NAO yields a di polar correlationstructure, which is comparable to the correlation-pattern between the NAO and the zonal wind. The barotropic feature is predominant in each cross-section, moreover the regression-patterns show an eastward increasing tilt of the vertical axis towards north with a clear downward propagation of the northern center of activity from the middle troposphere to the lowest levels over Europe. It is shown that the NAO explains more than 30% of the total variance of interannual variability of the seasonal zonal energy fluxes, over the central Atlantic region even more than 40%, whereby anomalies reach up to 30% of the seasonal mean fluxes during extreme NAO-phases. Subsequently, flux anomalies associated with the Niño3-SST are analysed to clarify the dependence upon ENSO. In western parts of the Atlantic region, the Niño3-SST explains less than 5% of the variability of the zonal energy fluxes. Correlations between them are widely non significant in the analysed area. Nevertheless, strong El Niño events tend to cause stronger flux anomalies. In the last section, vertically integrated energy fluxes through the western and eastern boundary of the Atlantic region (represented as 60°W and 0°W longitudes) are computed. Fluctuations of the total energy flux through these sections are proved to be highly correlated with the NAO. The zonal convergence of flux anomalies between the boundaries show weak linkages to NAO, so that meridional atmospheric energy transport anomalies associated with NAO in the Atlantic region are assumed.

    Modelluntersuchungen zum Einfluss thermohaliner und windgetriebener Zirkulationsschwanckundgen auf die marine CO2-Aufnahme (2004)
    Details
    Publication Date: 2024-07-01
    Description: The aim of this study is to examine the influence of both thermohaline and wind driven circulation changes on oceanic and atmospheric CO2-concentrations. For this the biopump three- and seven-box models of Toggweiler [1999] are integrated from an interglacial into a glacial steady state and vice versa. In contrast to previous studies which concentrated on steady state situations, here the focus is on transient CO2-concentrations after a sudden change in thermohaline and wind driven circulations. In addition timescales and amplitudes of atmospheric pC02-concentrations during the transition are compared to measurements of ice core datasets.

    Publication Date: 2024-07-01
    Description: Studies of animal populations are important and, in the case of harbour seals, have been considered particularly valuable as part of an assessment of the distemper epidemic that has plagued the northern Atlantic population over the last years. Head counts of seals by plane- or ship-based observers are biassed because these animals spent a large percentage of their time underwater. This study seeks to quantify the time that seals can be seen so that head counts can be appropriately corrected. Over the last two years 19 harbour seals were equipped with multiple channel loggers which recorded dive depth every 3-15 seconds for periods lasting up to two month. In this work the diving behaviour of 11 seals, from which the devices could be recovered, was analysed to examine how much time the animals spent at the water surface and on land where they can be counted and the extent to which this varied according to behaviour and water depth. Dives executed conformed broadly to either U- or V-shaped dives according to their profile of depth over time. During U-shaped dives, which comprised about 80% of all dives, the seals always apparently dived to the seabed. Both dive duration and surface duration changed systematically with maximum depth reached during the dive, both increasing: surface time as a cubed function of water depth and dive duration as a squared function of water depth. The percentage time that seals spent at the water surface where they can be seen could described by the equation: % time at surface = (21,55+0,00016( depth)3) / (21,55+0,00016(depth)3)+(156, 7+6,07(1n(depth)2) X 100 Implementation of this formula on seal-counting transects should help in calculations of seal density at sea and thus be useful in population assessments.

    Induzieren Herbivore Verteidigung bei Makroalgen der portugiesischen Südküste? (2004)
    Details
    Publication Date: 2024-07-01
    Description: Obwohl im terrestrischen Bereich die induzierte Verteidigung durch Herbivore weit verbreitet ist, sind nur wenige Beispiele für marine Makrophyten bekannt. In dieser Studie wurden in zwei Laborexperimenten die Effekte von 1. direktem Fraß durch Amphipoden und 2. wassergetragenen Signalen von Fraß an benachbarten Algen und 3. der Effekt eines benachbarten Konsumenten auf die Antifraßverteidigung von sieben bzw. vier Makroalgen der portugiesischen Südküste untersucht. Die Braunalge Fucus vesiculosus und die Rotalge Sphaerococcus coronopifolius wiesen nach einer Behandlungsphase von 14 Tagen mit drei Amphipodenarten als Konsumenten eine induzierte Verteidigung in intakten Algenstücken auf. Diese Verteidigung wurde innerhalb von zwei Wochen wieder herabgesetzt, nachdem der Fraßdruck reduziert wurde. Für F. vesicu/osus konnte weiter nachgewiesen werden, dass die Verteidigung teilweise auf den lipophilen Bestandteilen der Pflanze beruht. Außerdem konnte für beide Algenarten eine saisonale Variation in der Intensität des Auftretens der Verteidigungsinduktion beobachtet werden. Weiterhin konnte festgestellt werden, dass wassergetragene Signale von 1. benachbartem Fraß sowie 2. von einem benachbarten Konsumenten, der nicht fraß, eine Antifraßverteidigung auslösen. Diese Studie zeigt, dass nicht nur Braunalgen dazu in der Lage sind, auf die Signale von Herbivoren in kürzester Zeit - also innerhalb von 14 Tagen - zu reagieren, sondern dass dies auch bei Rotalgen der Fall sein kann. Nach unserem Wissen ist dies die erste Studie, die zeigt, dass bei Rotalgen eine Verteidigung durch direkten Fraß induziert werden kann und dass wassergetragene Signale von einem nicht fressenden Konsumenten ebenfalls eine Verteidigung auslösen. Hieran ist zu erkennen, dass induzierte Verteidigung durch direkten Fraß wie auch durch wassergetragene Signale in marinen Makrophyten eine größere ökologische Relevanz spielt, als bisher angenommen wurde.

    Bewertung des Klimas von Österreich auf der Grundlage von human-biometeorologischen Indizes und geo-statistischen Methoden für Zwecke des Fremdenverkehrs (2004)

    Publication Date: 2024-07-01
    Description: Within the context of the Austrian Climate and Health Tourism Initiative (ACTIVE) this research supports a contribution from scientific basis to the improved use of the healthy effect of climate to Austria. The Central Institute of Meteorology and Geodynamics (ZAMG) provided us climate data records available by stations within of Austria, as well as a synoptical data records available by stations within and outside of Austria. For the investigation period of 1. January 1996 until 31. December 2000 series of measurements of 201 climatic stations and 278 synoptical stations are available. Emphasis of the analysis is the comparison of these two station types on the basis of the Physiological Equivalent Temperature (PET). It considers the influences on the Energy Balance of Humans by air temperature, vapour presssure, wind velocity, as well as short and long-wave radiant fluxes from the environment to the human body as the mean radiant temperature. This characteristic is to be modelled by RayMan, a modell for the mean radiant temperature and thermal indices in urban structures and divided into individual temperature ranges according to the unit degrees Celsius. It makes a classification possible which can be set into relation to comfort stages. The confrontation of both station types at midday takes place via frequency distributions from PET classes concerning the calendar months in per cent and in days per year. This time of day is for tourists and healthy oriented people decisive of choosing an climatic adequate region which is caused of a high activity rate in this hours. Further a regionalization is accomplished based on a regression analysis. This method places PET in relationship with geographical latitude, geographical length, height over the sea level, slope, aspect ratio and land use. So it makes the transferring of PET into the space possible. The generated maps show both the PET distribution in the calendar months and the distribution of individual classes based in each case on climatic and synoptical data records. The maps include a description of the bioclimate and makes a regional comparison of both data records possible. It shows similarly spatial and temporally tendencies in both kind of data records which have nearly the same high significant regression coefficients. A smaller data lack in climate data records and different measurement times at 14 o’clock LST for climate stations and at 13 o’clock CET for synoptical stations cause minor changes which can be observed in the mean radiant temperature and air temperature of both kind of stations. They lead to a lower PET in maps generated by synoptical data records. At all both show more detailed maps with a high resolution of 1 km as it was possible in former studies.

    Description: During the ANT V14 (1986187) and ANT V113 (1987188) cruises of R.V. Polarstern sedirnents from the eastern, southern and central Weddell Sea were sarnpled with a boxcorer andlor a multicorer. The 24 sampling locations are distributed over the whole depth range, from shelf to pelagic environments. Porewater concentrations of aluminium, fluoride, manganese, nitrate, nitrite, oxygen and silicate, the pH and the alkalinity were measured. Of the sediment the opal, calcium carbonate and organic carbon content were quantified. The 210Pb-profile was measured for three sedirnent cores. This investigation deals with the estimation of the amounts of opal and organic carbon (Corg) that are transported into the sediment, the regional distribution of these flux rates and the early diagenetic processes that control the preservation of organic carbon and opal in the sediment. The flux and degradation rates of organic carbon were determined by modelling the rneasured oxygen and nitrate profiles. The highest flux and degradation rates were found in the eastern shelf sediments. Due to the high Corg-flux (〉500 mmol C m**-2 a-1) in this area the oxic environment is restricted to the upper 3 cm of the sediment. In contrast to this, the oxic Zone in the pelagic sedirnents of the Weddell Sea has probably an extension of a few meters. The Corg-flux here, computed from the flux of nitrate throug h the sedimentlwater-interface, is less than 50 mmol C m**-2 a**-1. The flux of organic carbon into the sediments of the continental slope area is usually intermediate between the values computed for the shelf and pelagic sediments. Exceptions are the continental slope region north of Halley Bay. In these sediments the measured oxygen and nitrate profiles indicate a relatively high organic carbon flux. This could be a result of the recurrent development of a coastal polynia in this area. The bioturbation rate determined in this region by a 210Pb-profile is 0,019 cm**2 a**-1. In the Weddell Sea the opal content at the sediment surface (0-1 cm depth) varies between 0,1 and 7 %-wt. These opal concentrations are rnuch lower than the opal contents determined for the sediments of the ROSS Sea by Ledford-Hoffmann et al. (1986 doi:10.1016/0016-7037(86)90263-2). Therefore the importance of the Antarctic shelf regions for the global silica cycle as stated by Ledford-Hoffmann et al. (1986) has to be reconsidered. The regional distribution of the opal content and the computed opal flux rates are correlated with the organic carbon flux rates. The processes controlling the preservation of opal are discussed based On the measured aluminium and silicate concentrations in the Pore water and the opal content of the sediment.The depth distribution of the Si- and Al-concentration of the porewater indicates that the reconstitution of clay minerals takes place in the immediate vicinity of the sediment-water nterface. A characterization of these minerals e.g. the estimation of the Si/AI-ratio (Mackin and Aller, 1984 a doi:10.1016/0016-7037(84)90251-5, 1984 b doi:10.1016/0016-7037(84)90252-7) is not possible. With the program WATEQ2 saturation indices are computed to estimate which minerals could reconstitute. In this context the applicability of programs like WATEQ2 for computations of the species distribution and saturation indices in solutions with the ionic strength of sea water is investigated.

    Description: The general knowledge of the hydrographic structure of the Southern Ocean is still rather incomplete since observations particularly in the ice covered regions are cumbersome to be carried out. But we know from the available information that thermohaline processes have large amplitudes and cover a wide range of scales in this part of the world ocean. The modification of water masses around Antarctica have indeed a worldwide impact, these processes ultimately determine the cold state of the present climate in the world ocean. We have converted efforts of the German and Russian polar research institutions to collect and validate the presently available temperature, salinity and oxygen data of the ocean south of 30°S latitude. We have carried out this work in spite of the fact that the hydrographic programme of the World Ocean Circulation Experiment (WOCE) will provide more new information in due time, but its contribution to the high latitudes of the Southern Ocean is quite sparse. The modified picture of the hydrographic structure of the Southern Ocean presented in this atlas may serve the oceanographic community in many ways and help to unravel the role of this ocean in the global climate system. This atlas could only be prepared with the altruistic assistance of many colleagues from various institutions worldwide who have provided us with their data and their advice. Their generous help is gratefully acknowledged. During two years scientists from the Arctic and Antarctic Research Institute in St. Petersburg and the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven have cooperated in a fruitful way to establish the atlas and the archive of about 38749 validated hydrographic stations. We hope that both sources of information will be widely applied for future ocean studies and will serve as a reference state for global change considerations.

    Description: Detrital modes for 524 deep-marine sand and sandstone samples recovered on circum-Pacific, Caribbean, and Mediterranean legs of the Deep Sea Drilling Project and the Ocean Drilling Program form the basis for an actualistic model for arc-related provenance. This model refines the Dickinson and Suczek (1979) and Dickinson and others (1983) models and can be used to interpret the provenance/tectonic history of ancient arc-related sedimentary sequences. Four provenance groups are defined using QFL, QmKP, LmLvLs, and LvfLvmiLvl ternary plots of site means: (1) intraoceanic arc and remnant arc, (2) continental arc, (3) triple junction, and (4) strike-slip-continental arc. Intraoceanic- and remnant-arc sands are poor in quartz (mean QFL%Q 〈 5) and rich in lithics (QFL%L 〉 75); they are predominantly composed of plagioclase feldspar and volcanic lithic fragments. Continental-arc sand can be more quartzofeldspathic than the intraoceanic- and remnant-arc sand (mean QFL%Q values as much as 10, mean QFL%F values as much as 65, and mean QmKP%Qm as much as 20) and has more variable lithic populations, with minor metamorphic and sedimentary components. The triple-junction and strike-slip-continental groups compositionally overlap; both are more quartzofeldspathic than the other groups and show highly variable lithic proportions, but the strike-slip-continental group is more quartzose. Modal compositions of the triple junction group roughly correlate with the QFL transitional-arc field of Dickinson and others (1983), whereas the strike-slip-continental group approximately correlates with their dissected-arc field.

    Biogenic silica and silicic acid benthic fluxes of a North-eastern Atlantic Abyssal Locality (2001)

    Description: Within the framework of the EU-funded BENGAL programme, the effects of seasonality on biogenic silica early diagenesis have been studied at the Porcupine Abyssal Plain (PAP), an abyssal locality located in the northeast Atlantic Ocean. Nine cruises were carried out between August 1996 and August 1998. Silicic acid (DSi) increased downward from 46.2 to 213 µM (mean of 27 profiles). Biogenic silica (BSi) decreased from ca. 2% near the sediment-water interface to 〈1% at depth. Benthic silicic acid fluxes as measured from benthic chambers were close to those estimated from non-linear DSi porewater gradients. Some 90% of the dissolution occurred within the top 5.5 cm of the sediment column, rather than at the sediment-water interface and the annual DSi efflux was close to 0.057 mol Si/m**2/yr. Biogenic silica accumulation was close to 0.008 mol Si/m**2/yr and the annual opal delivery reconstructed from sedimentary fluxes, assuming steady state, was 0.065 mol Si/m**2/yr. This is in good agreement with the mean annual opal flux determined from sediment trap samples, averaged over the last decade (0.062 mol Si/m**2/yr). Thus ca. 12% of the opal flux delivered to the seafloor get preserved in the sediments. A simple comparison between the sedimentation rate and the dissolution rate in the uppermost 5.5 cm of the sediment column suggests that there should be no accumulation of opal in PAP sediments. However, by combining the BENGAL high sampling frequency with our experimental results on BSi dissolution, we conclude that non-steady state processes associated with the seasonal deposition of fresh biogenic particles may well play a fundamental role in the preservation of BSi in these sediments. This comes about though the way seasonal variability affects the quality of the biogenic matter reaching the seafloor. Hence it influences the intrinsic dissolution properties of the opal at the seafloor and also the part played by non-local mixing events by ensuring the rapid transport of BSi particles deep into the sediment to where saturation is reached.

    Description: The 10Be records of four sediment cores forming a transect from the Norwegian Sea at 70°N (core 23059) via the Fram Strait (core 23235) to the Arctic Ocean at 86°N (cores 1533 and 1524) were measured at a high depth resolution. Although the material in all the cores was controlled by different sedimentological regimes, the 10Be records of these cores were superimposed by glacial/interglacial changes in the sedimentary environment. Core sections with high 10Be concentrations ( 〉1 * 10**9 at/g) are related to interglacial stages and core sections with low10Be concentrations ( 〈0.5 * 10**9 at/g) are related to glacial stages. Climatic transitions (e.g., Termination II, 5/6) are marked by drastic changes in the 10Be concentrations of up to one order of magnitude. The average 10Be concentrations for each climatic stage show an inverse relationship to their corresponding sedimentation rates, indicating that the 10Be records are the result of dilution with more or less terrigenous ice-rafted material. However, there are strong changes in the 10Be fluxes (e.g., Termination II) into the sediments which may also account for the observed oscillations. Most likely, both processes affected the 10Be records equally, amplifying the contrast between lower (glacials) and higher (interglacials) 10Be concentrations. The sharp contrast of high and low 10Be concentrations at climatic stage boundaries are an independent proxy for climatic and sedimentary change in the Nordic Seas and can be applied for stratigraphic dating (10Be stratigraphy) of sediment cores from the northern North Atlantic and the Arctic Ocean.

    Sedimentology of surface sediments from the eastern central Arctic Ocean (1994)

    Description: Results from a detailed sedimentological investigation of surface sediments from the eastern Arctic Ocean indicate that the distribution of different types of sediment facies is controlled by different environmental processes such as sea-ice distribution, terrigenous sediment supply, oceanic currents, and surface-water productivity. In comparison to other open-ocean environments, total organic carbon contents are high, with maximum values in some deep-basin areas as well as west and north of Svalbard. In general, the organic carbon fraction is dominated by terrigenous material as indicated by low hydrogen index values and high C/N ratios, probably transported by currents and/or sea ice from the Eurasian Shelf areas. The amount of marine organic carbon is of secondary importance reflecting the low-productivity environment described for the modern ice-covered Arctic Ocean. In the area north of Svalbard, some higher amounts of marine organic matter may indicate increased surface-water productivity controlled by the inflow of the warm Westspitsbergen Current (WSC) into the Arctic Ocean and reduced sea-ice cover. This influence of the WSC is also supported by the high content of biogenic carbonate recorded in the Yermak Plateau area. The clay mineral distribution gives information about different source areas and transport mechanisms. Illite, the dominant clay mineral in the eastern central Arctic Ocean sediments, reaches maximum values in the Morris-Jesup-Rise area and around Svalbard, indicating North Greenland and Svalbard to be most probable source areas. Kaolinite reaches maximum values in the Nansen Basin, east of Svalbard, and in the Barents Sea. Possible source areas are Mesozoic sediments in the Barents Sea (and Franz-Josef-Land). In contrast to the high smectite values determined in sea-ice samples, smectite contents are generally very low in the underlying surface sediments suggesting that the supply by sea ice is not the dominant mechanism for clay accumulation in the studied area of the modern central Arctic Ocean.

    Age models and stable isotopes of sediment cores from the northern seas (1992)

    Description: Oxygen and carbon isotope measurements were carried out on tests of planktic foraminifers N. pachyderma (sin.) from eight sediment cores taken from the eastern Arctic Ocean, the Fram Strait, and the lceland Sea, in order to reconstruct Arctic Ocean and Norwegian-Greenland Sea circulation patterns and ice covers during the last 130,000 years. In addition, the influence of ice, temperature and salinity effects on the isotopic signal was quantified. Isotope measurements on foraminifers from sediment surface samples were used to elucidate the ecology of N. pachyderma (sin.). Changes in the oxygen and carbon isotope composition of N. pachyderma (sin.) from sediment surface samples document the horizontal and vertical changes of water mass boundaries controlled by water temperature and salinity, because N. pachyderma (sin.) shows drastic changes in depth habitats, depending on the water mass properties. It was able to be shown that in the investigated areas a regional and spatial apparent increase of the ice effect occurred. This happened especially during the termination I by direct advection of meltwaters from nearby continents or during the termination and in interglacials by supply of isotopically light water from rivers. A northwardly proceeding overprint of the 'global' ice effect, increasing from the Norwegian-Greenland Sea to the Arctic Ocean, was not able to be demonstrated. By means of a model the influence of temperature and salinity on the global ice volume signal during the last 130,000 years was recorded. In combination with the results of this study, the model was the basis for a reconstruction of the paleoceanographic development of the Arctic Ocean and the Norwegian-Greenland Sea during this time interval. The conception of a relatively thick and permanent sea ice cover in the Nordic Seas during glacial times should be replaced by the model of a seasonally and regionally highly variable ice cover. Only during isotope stage 5e may there have been a local deep water formation in the Fram Strait.

    Description: Analyses of benthic foraminifera in sediment cores taken at about 1000 m water depth at the Yermak Plateau and the Barents Sea slope, adjacent to the position of the ice-sheet edge during the Last Glacial Maximum, show that paleoproductivity was reduced to about a third of its present level during peak glacial stadials. These reduced values are still higher than values for modern, permanently ice-covered regions, suggesting that the core locations were at least partially ice-free even during stadials. Paleoproductivity at the core locations was higher than or equal to that of today during initial deglaciations and warm substages. Peak paleoproductivity occurred in samples with low-salinity surface waters as indicated by oxygen isotope values of planktonic foraminifera, and slightly after increased abundance of 'Atlantic species', suggesting that enhanced advection of warmer waters from the Atlantic supported the initial ice-sheet retreat. During the Holocene Climatic Optimum productivity was much less than at present on the Yermak Plateau, high at the Barents Sea site, perhaps because of increased advection of Atlantic water to the latter site and heavier ice coverage at the former. After this optimum, paleoproductivity at both sites was similar, with slightly lower values during cold periods such as the Little Ice Age.

    Benthic foraminifera of surface sediments in the Arctic Ocean (1994)

    Description: The Recent distribution of living and dead benthic foraminifera of the Arctic Ocean proper has been examined in surface sediments that were sampled during the International Arctic Ocean Expedition 1991 (Arctic 91). The samples represent the Amundsen and Nansen Basins, the Morris Jesup Rise, and the Yermak Plateau from 90°N to 79°42.4'N, 05°15.6'E. Due to the technical difficulties of deep-sea drilling in the Arctic Ocean these areas have, until now, been investigated only in very low density sampling. The Arctic 91 sites of this study cover a water depth range between 552 and 4375 m and represent three sites which are seasonally ice-free, although not yearly, while the other sites are characterized by permanent sea-ice. There is a Recent production of benthic foraminifera in the whole investigation area and all surface samples contain both benthic and planktonic foraminifera. Abyssal assemblages are recorded in the Amundsen and Nansen Basins where Stetsonia arctica dominates with high abundances. It is, however, also possible to distinguish these two basins by the use of diagnostic species. At intermediate water depths (500 to 2000-2500 m) the faunas show higher diversities and higher abundances of Atlantic species than the deep-sea sites. Mixing of North Atlantic water down to approximately 2500 m, is suggested to explain the influx of Atlantic species on the Yermak Plateau and the Morris Jesup Rise. The foraminiferal tests are well preserved within the investigation area and dissolution does not seem to be very obvious in the deeper areas. There is no evidence from the Recent foraminiferal faunas that the bottom waters of the eastern, central Arctic Ocean are undersaturated with respect to calcium carbonate and the deep-sea areas appear, therefore, to lie above the present CCD.

    Stable oxygen and carbon isotope ratios of Neogloboquadrina pachyderma from Latest Pleistocene to Holocene sediments of the eastern central Arctic Ocean (1994)

    Description: A high-resolution study including oxygen and carbon stable isotopes as well as carbonate and total organic carbon contents, has been performed on undisturbed near-surface (0-40 cm) sediment sequences taken in the eastern Arctic Ocean during the international Arctic 91 Expedition. Based on the oxygen stable isotope records measured on Neogloboquadrina pachyderma (sin.) and AMS 14C dating, the upper 10 to 20 cm of the sediment sequences represent isotope stage 1, and the base of Termination I (15.7 ka) can be identified very well. Stage 1 sedimentation rates vary between 0.4 and 〉2.0 cm/kyr. In general, glacial stage 2 sedimentation rates are probably lower and vary between 0.4 and 0.7 cm/kyr. The glacial-interglacial shifts in delta18O values of N. pachyderma sin. may reach values of 1.3 to 2.5 per mil indicating (1) that, in addition to the glacial-interglacial global ice-volume signal, changes in surface-water salinity have effected the isotope records and (2) that these salinity changes have varied laterally. Glacial-interglacial differences in salinity were small in the Lomonosov Ridge area (0-0.4 per mil) and relatively high in the Morris-Jesup-Rise area (up to 1.4 per mil). This implies that the supply of low-saline waters onto the Eurasian shelves and its further transport into the central Arctic Ocean via the Transpolar Drift should have continued during the last glacial and should have significantly influenced the surface water characteristics in parts of the central Arctic. On the Morris-Jesup-Rise, on the other hand, the glacial low-saline-water signal at that time was strongly reduced in comparison to the modern situation. At the glacial-interglacial stage 1/2 boundary, a strong meltwater signal is recorded in a sharp depletion in delta18O as well as delta13C. This central Arctic Ocean meltwater event can be correlated from the Makarov Basin through the Lomonosov Ridge and Amundsen Basin to the eastern Gakkel Ridge. The beginning of this event is AMS 14C dated at 15.7 ka, i.e., significantly older than the major decrease in the global ice-volume signal which occurs between 9 and 13.5 ka. Large amounts of freshwater/meltwater were probably supplied from the Eurasian continent due to the decay of the Barents-Sea-Ice-Sheet, causing this distinct early meltwater anomaly in the central Arctic Ocean. The extension of a well-oxygenated surface-near water mass in the Arctic Ocean and (at least seasonal) open-ice conditions and some increased bioproductivity were probably established at the end of Termination I, as indicated by the increase in delta13C to modern values as well as increased carbonate (i.e., foraminifers, coccoliths, ostracodes) and total organic carbon contents.

    Description: The Mid-Pleistocene transition (MPT) of the global climate system, initiated by a shift towards much larger northern hemisphere ice shields at around 920 ka and ending with predominance of 100 kyr ice age cyclicity since about 640 ka, is one of the fundamental enigmas in Quaternary climate evolution. Climate proxy records not exclusively linked to global ice volume are necessary to advance understanding of the MPT. Here we present a high-resolution Pleistocene magnetic susceptibility time series of 12 sediment cores from the subtropical South Atlantic essentially reflecting dissolution driven variations in carbonate accumulation controlled by changes in deep water circulation. In addition to characteristics known from delta18O records, the data sets reveal three remarkable features intimately related to the MPT: (1) an all-Pleistocene minimum of carbonate accumulation in the South Atlantic at 920 ka, (2) a MPT interim state of reduced carbonate deposition, indicating that the MPT period may have been a discrete state of the Pleistocene deep water circulation and climate system and (3) a terminal MPT event at around 540-530 ka documented in several peculiarities such as thick laminated layers of the giant diatom Ethmodiscus rex.

    Description: Sr and Nd isotopic compositions of Late Quaternary surface sediment and sediment cores from the south Atlantic and southeast Pacific sectors of the Southern Ocean are used to constrain the provenance and transport mechanisms of their terrigenous component. We report isotopic and mineralogical data for core samples from three localities, the Mid-Atlantic Ridge at 41°S and the northern and southern Scotia Sea. In addition, data for surface sediment samples from the south Atlantic and southeast Pacific sectors of the Southern Ocean are presented. The variations of Sr and Nd isotopic compositions of the bulk sediment samples in all cores were correlated with the magnetic susceptibility of the sediment and with the inferred glacial-interglacial stages. The isotopic data indicate that, during glacial periods, sediment was delivered from continental crust with a shorter residence time than that supplying material during interglacial periods. At the core site near the Mid-Atlantic Ridge, Nd isotopic, combined with mineralogical evidence indicates interglacial period deposition of a relatively high amount of kaolinite and silt with low epsilon-Nd values 〈 -8. The material was probably supplied by North Atlantic Deep Water from low latitudes. For glacial periods, a high contribution of silt and clay with epsilon-Nd 〉 -4.5, probably derived from southern South America, was indicated. The glacial-interglacial shift in sources may be due to either a decreasing influence of North Atlantic Deep Water during glacial times or by a larger contribution of glaciogenic detritus from southern South America. At the core site in the northern Scotia Sea, sediment of interglacial periods is dominated by smectite with epsilon-Nd 〈 - 6 and silt with epsilon-Nd 〉 -4. We suggest that smectite was derived from the Falkland shelf and silt was derived from the Argentinian shelf. During glacial periods, the Argentinian shelf was an important source for silt and chlorite with epsilon-Nd 〉 -4. The contribution from the Falkland shelf seems to have remained similar during glacial and interglacial periods. Hydrographic transport by bottom currents and turbidites could account for the high glacial detrital flux. An evaluation of the significance of an aeolian contribution to deep sea sediment suggests that it plays only a minor role. In the southern Scotia Sea, the Antarctic Peninsula is considered an important source for young material with epsilon-Nd 〉 -4, in particular during glacial periods. During interglacial periods, sediment supply from the Antarctic Peninsula was lower than during glacial times, resulting in a relatively high contribution of old material (epsilon-Nd 〈 -8) from East Antarctica. Deep water currents and icebergs could account for the transport of the old component to the southern Scotia Sea. The accumulation rates of material from the various source regions for glacial times are in agreement with an increase in the strength of the Antarctic Circumpolar Current. The production rate and the circulation pattern of bottom water in the Weddell Sea appear to have remained similar over most of the last 150 kyr.

    Description: We reconstructed changes of temperature, salinity, and productivity within the southern Peru-Chile Current during the last 8000 years from a high-resolution sediment core recovered at 41°S using alkenones, isotope ratios of planktic foraminifera, biogenic opal, and organic carbon. Paleotemperatures and paleosalinities reached maximum values at ~5500 years ago and thereafter declined to modern values, whereas paleoproductivity continuously increased throughout the last 8000 years. We ascribe these long-term Holocene trends primarily to latitudinal shifts of the Antarctic Circumpolar Current (ACC). The concurrence with shifts in the position of the Southern Westerlies points to a common response of atmospheric and oceanographic circulation patterns off southern Chile. Millennial- to centennial-scale fluctuations of paleotemperatures and paleosalinities, on the other hand, lag displacements in the position of the Southern Westerlies but reveal a significant correlation to short-term temperature changes in Antarctica, indicating a high-latitude control of the ACC at these timescales.

    Description: The upper water column in the Fram Strait and the outer Laptev Sea was sampled for water column isotopes and living planktic foraminifer species Neogloboquadrina pachyderma (sinistral coiling) (Ehrenberg), 1861 and Turborotalita quinqueloba (Natland),1938. Their shell delta18O and delta13C values are compared to water oxygen and dissolved inorganic carbon isotope data to determine the environmental influence on the foraminifers' isotopic ratio. Major controls on the oxygen isotope composition of both species are the shallow depth habitat under permanent ice coverage, the low salinity surface layer, and the rate of metabolic activity. None of the specimens precipitated its shell in isotopic equilibrium with the ambient sea water. They are all depleted in 13C and 18O, attributed to a species-specific vital effect. For nonencrusted N. pachyderma (sin.) in the 125-250 µm size class, this vital effect amounts to 1.3 per mil in delta18O and 2.0 per mil in delta13C. It increases to higher values in waters under permanent ice cover. T. quinqueloba reveals a mean vital effect of about 1.3 per mil in delta18O and 2.6 per mil in delta13C. The general isotopic trends are similar for N. pachyderma (sin.) and T. quinqueloba. Differences in the species' isotope ratio at the same sites are caused by different calcification depths and metabolic activity. The oxygen isotope composition of N. pachyderma (sin.) shows a relationship to salinity measurements and indicates that it is a good quantitative proxy for salinity reconstructions, while no relationship exists in this region between N. pachyderma (sin.) oxygen isotopes and water temperature.

    Publication Date: 2024-07-01
    Description: The timing and magnitude of sea-surface temperature (SST) changes in the tropical southern South China Sea (SCS) during the last 16,500 years have been reconstructed on a high-resolution, 14C-dated sediment core using three different foraminiferal transfer functions (SIMMAX28, RAM, FP-12E) and geochemical (Uk'37) SST estimates. In agreement with CLIMAP reconstructions, both the FP-12E and the Uk'37 SST estimates show an average late glacial-interglacial SST difference of 2.0°C, whereas the RAM and SIMMAX28 foraminiferal transfer functions show only a minor (0.6°C) or no consistent late glacial-interglacial SST change, respectively. Both the Uk'37 and the FP-12E SST estimates, as well as the planktonic foraminiferal delta18O values, indicate an abrupt warming (ca. 1°C in 〈200 yr) at the end of the last glaciation, synchronous (within dating uncertainties) with the Bølling transition as recorded in the Greenland Ice Sheet Project 2 (GISP2) ice core, whereas the RAM-derived deglacial SST increase appears to lag during this event by ca. 500 yr. The similarity in abruptness and timing of the warming associated with the Bølling transition in Greenland and the southern SCS suggest a true synchrony of the Northern Hemisphere warming at the end of the last glaciation. In contrast to the foraminiferal transfer function estimates that do not indicate any consistent cooling associated with the Younger Dryas (YD) climate event in the tropical SCS, the Uk'37 SST estimates show a cooling of ca. 0.2-0.6°C compared to the Bølling-Allerød period. These Uk'37 SST estimates from the southern SCS argue in favor of a Northern Hemisphere-wide, synchronous cooling during the YD period.

    Publication Date: 2024-07-01
    Description: Improved multiparameter records from the northern Barents Sea margin show two prominent freshwater pulses into the Arctic Ocean during MIS 5 that significantly disturbed the regional oceanic regime and probably affected global climate. Both pulses are associated with major iceberg-rafted debris (IRD) events, revealing intensive iceberg/sea ice melting. The older meltwater pulse occurred near the MIS 5/6 boundary (~131,000 yr ago); its ~2000 year duration and high IRD input accompanied by high illite content suggest a collapse of large-scale Saalian Glaciation in the Arctic Ocean. Movement of this meltwater with the Transpolar Drift current into the Fram Strait probably promoted freshening of Nordic Seas surface water, which may have increased sea-ice formation and significantly reduced deep-water formation. A second pulse of freshwater occurred within MIS 5a (~77,000 yr ago); its high smectite content and relatively short duration is possibly consistent with sudden discharge of Early Weichselian ice-dammed lakes in northern Siberia as suggested by terrestrial glacial geologic data. The influence of this MIS 5a meltwater pulse has been observed at a number of sites along the Transpolar Drift, through Fram Strait, and into the Nordic Seas; it may well have been a trigger for the North Atlantic cooling event C20.

    Description: Organic carbon fluxes through the sediment/water interface in the high-latitude North Atlantic were calculated from oxygen microprofiles. A wire-operated in situ oxygen bottom profiler was deployed, and oxygen profiles were also measured onboard (ex situ). Diffusive oxygen fluxes, obtained by fitting exponential functions to the oxygen profiles, were translated into organic carbon fluxes and organic carbon degradation rates. The mean Corg input to the abyssal plain sediments of the Norwegian and Greenland Seas was found to be 1.9 mg C/m**2/d. Typical values at the seasonally ice-covered East Greenland continental margin are between 1.3 and 10.9 mg C/m**2/d (mean 3.7 mg C/m**2/d), whereas fluxes on the East Greenland shelf are considerably higher, 9.1-22.5 mg C/m**2/d. On the Norwegian continental slope Corg fluxes of 3.3-13.9 mg C/m**2/d (mean 6.5 mg C/m**2/d) were found. Fluxes are considerably higher here compared to stations on the East Greenland slope at similar water depths. By repeated occupation of three sites off southern Norway in 1997 the temporal variability of diffusive O2 fluxes was found to be quite low. The seasonal signal of primary and export production from the upper water column appears to be strongly damped at the seafloor. Degradation rates of 0.004-1.1 mg C/cm**3/a at the sediment surface were calculated from the oxygen profiles. First-order degradation constants, obtained from Corg degradation rates and sediment organic carbon content, are in the range 0.03-0.6/a. Thus, the corresponding mean lifetime of organic carbon lies between 1.7 and 33.2 years, which also suggests that seasonal variations in Corg flux are small. The data presented here characterize the Norwegian and Greenland Seas as oligotrophic and relatively low organic carbon deep-sea environments.

    Description: Terrigenous sediment parameters in modern sea-bottom samples and sediment cores of the South Atlantic are used to infer variations in detrital sources and modes of terrigenous sediment supply in response to environmental changes through the late Quaternary climate cycles. Massaccumulation rates of terrigenous sediment and fluxes of ice-rafted detritus are discussed in terms of temporal variations in detrital sediment input from land to sea. Grain-size parameters ofterrigenous mud document the intensity of bottom-water circulation, whereas clay-mineral assemblages constrain the sources and marine transport routes of suspended fine-grained particulates, controlled by the modes of sediment input and patterns of ocean circulation. The results suggest low-frequency East Antarctic ice dynamics with dominant 100-kyr cycles and high rates of Antarctic Bottom Water formation and iceberg discharge during interglacial times. In contrast, the more subpolar ice masses of the Antarctic Peninsula also respond to short-term climate variability with maximum iceberg discharges during glacial terminations related to the rapid disintegration of advanced ice masses. In the northern Scotia Sea, increased sediment supply from southern South America points to extended ice masses in Patagonia during glacial times. In the southeastern South Atlantic, changes in regional ocean circulation are linked to global thermohaline ocean circulation and are in phase with northern-hemispheric processes of ice build-up and associated formation of North Atlantic Deep Water, which decreased during glacial times and permitted a wider extension of southern-source water masses in the study area.

Species numbers, abundances and biomasses were extremely low, and generally varied between 0 to 11/0.02 m**2, 0 to 850 individuals/m**2, and 0 to 82.65 g/m**2, respectively. A total of 42 species was found. The Amphipod Jassa marmorata was the most common species. Both numbers and biomasses of suspension-feeding species increased towards the Lomonosov Ridge, probably due to lateral transport of organic material by deep currents along the ridge.

    Description: On the basis of various lithological, mircopaleontological and isotopic proxy records covering the last 30,000 calendar years (cal kyr) the paleoenvironmental evolution of the deep and surface water circulation in the subarctic Nordic seas was reconstructed for a climate interval characterized by intensive ice-sheet growth and subsequent decay on the surrounding land masses. The data reveal considerable temporal changes in the type of thermohaline circulation. Open-water convection prevailed in the early record, providing moisture for the Fennoscandian-Barents ice sheets to grow until they reached the shelf break at ~26 cal. kyr and started to deliver high amounts of ice-rafted debris (IRD) into the ocean via melting icebergs. Low epibenthic delta18O values and small-sized subpolar foraminifera observed after 26 cal. kyr may implicate that advection of Atlantic water into the Nordic seas occurred at the subsurface until 15 cal. kyr. Although modern-like surface and deep-water conditions first developed at ~13.5 cal. kyr, thermohaline circulation remained unstable, switching between a subsurface and surface advection of Atlantic water until 10 cal. kyr when IRD deposition and major input of meltwater ceased. During this time, two depletions in epibenthic delta13C are recognized just before and after the Younger Dryas indicating a notable reduction in convectional processes. Despite an intermittent cooling at ~8 cal. kyr, warmest surface conditions existed in the central Nordic seas between 10 and 6 cal. kyr. However, already after 7 cal. kyr the present day situation gradually evolved, verified by a strong water mass exchange with the Arctic Ocean and an intensifying deep convection as well as surface temperature decrease in the central Nordic seas. This process led to the development of the modern distribution of water masses and associated oceanographic fronts after 5 cal. kyr and, eventually, to today's steep east-west surface temperature gradient. The time discrepancy between intensive vertical convection after 5 cal. kyr but warmest surface temperatures already between 10 and 6 cal. kyr strongly implicates that widespread postglacial surface warming in the Nordic seas was not directly linked to the rates in deep-water formation.

    Description: A multiparameter investigation including organic carbon, carbonate, opal, and planktic foraminifera was carried out on five sediment cores from the coastal upwelling area between 24°S and 33°S along the Peru-Chile Current to reconstruct the history of the paleoproductivity and its driving mechanisms during the last 40,000 years. Inferred from our data, we conclude that the Antarctic Circumpolar Current as the main nutrient source in this region mainly drives the productivity by its latitudinal shifts associated with climate change. Simplified, its northerly position during the last glacial led to enhanced productivities, and its southerly position during the Holocene caused lower productivities. At 33°S the paleoproductivity was additionally affected by the southern westerlies and records highest levels during the Last Glacial Maximum (LGM). North of 33°S, several factors (e.g., position and strength of the South Pacific anticyclone, wind stress, continental runoff, and El Niño Southern Oscillation events) supplementary influenced upwelling and paleoproductivity, where maximum values occurred prior to the LGM and during the deglaciation.

We especially use the iron content, measured with a time-resolution of ca. 10 yr on average, of 14C-accelerator mass spectrometry dated marine sediments as a proxy for the relative input of iron-poor Coastal Range and iron-rich Andean source rocks. Variations in this input are most likely induced by rainfall changes in the continental hinterland of the core position. Based on these interpretations, we find a pronounced rainfall variability on multi-centennial to millennial time-scales, superimposed on generally more arid conditions during the middle Holocene (7700 to 4000 cal yr B.P.) compared to the late Holocene (4000 to present). This variability and thus changes in the position of the Southern Westerlies are first compared to regional terrestrial paleoclimate data-sets from central and southern Chile. In order to derive possible wider implications and forcing mechanisms of the Holocene latitudinal shifts of the Southern Westerlies, we then compare our data to ice-core records from both tropical South America and coastal Antarctica. These records show similar bands of variability centered at ca. 900 and 1500 yr. Comparisons of band pass filters suggest a close connection of shifts of the Southern Westerlies to changes within the tropical climate system. The correlation to climate conditions in coastal Antarctica shows a more complicated picture with a phase shift at the beginning of the late Holocene coinciding with the onset of the modern state of El Niño-Southern Oscillation system. The presented data provide further evidence that the well known millennial-scale climate variability during the last glacial continued throughout the Holocene.

    Description: On the basis of 52 sediment cores, analyzed and dated at high resolution, the paleoceanography and climate of the Last Glacial Maximum (LGM) were reconstructed in detail for the Fram Strait and the eastern and central Arctic Ocean. Sediment composition and stable isotope data suggest three distinct paleoenvironments: (1) a productive region in the eastern to central Fram Strait and along the northern Barents Sea continental margin characterized by Atlantic Water advection, frequent open water conditions, and occasional local meltwater supply and iceberg calving from the Barents Sea Ice Sheet; (2) an intermediate region in the southwestern Eurasian Basin (up to 84-85°N) and the western Fram Strait characterized by subsurface Atlantic Water advection and recirculation, a moderately high planktic productivity, and a perennial ice cover that breaks up only occasionally; and (3) a central Arctic region (north of 85°N in the Eurasian Basin) characterized by a low-salinity surface water layer and a thick ice cover that strongly reduces bioproduction and bulk sedimentation rates. Although the total inflow of Atlantic Water into the Arctic Ocean may have been reduced during the LGM, its impact on ice coverage and halocline structure in the Fram Strait and southwestern Eurasian Basin was strong.

    Chemical composition of tephra from the Greenland-Iceland-Norwegian-Sea (2003)
    PANGAEA
    In:  Supplement to: Wallrabe-Adams, Hans-Joachim; Lackschewitz, Klas Sven (2003): Chemical composition, distribution, and origin of silicic volcanic ash layers in the Greenland–Iceland–Norwegian Sea: explosive volcanism from 10 to 300 ka as recorded in deep-sea sediments.

    Description: Explosive ocean island volcanism in the Greenland-Iceland-Norwegian Sea (GIN Sea) is indicated by marine tephra layers at 10-300 ka. Peaks of explosive volcanism occurred in oxygen isotope stages 8, 7, 5 and 1. The depositional age of the tephra was estimated using the oxygen isotope stratigraphy and dating of marine records. Geochemical analyses of the tephra layers show that all originate from Iceland. Here we report the characteristics of tephra from these major Icelandic events in 30 deep-sea cores from the GIN Sea. Our findings provide constraints on the distribution of tephra from the eruption source. For the Vedde Ash (oxygen isotope stage 1) we estimate a minimum fallout area of 2*10**5 km**2, stretching from central Greenland in the west and southern Sweden in the east, to 71°N in the GIN Sea. The magnitude of the eruption and the regional wind conditions controlled the extent and concentrations of these ash fallout events. Oceanic circulation and differential settling may have affected the distribution and final deposition of ash particles such as bubble wall shards.

    Global compilation of benthic data sets I (2004)

    Description: Approaches to quantify the organic carbon accumulation on a global scale generally do not consider the small-scale variability of sedimentary and oceanographic boundary conditions along continental margins. In this study, we present a new approach to regionalize the total organic carbon (TOC) content in surface sediments (〈5 cm sediment depth). It is based on a compilation of more than 5500 single measurements from various sources. Global TOC distribution was determined by the application of a combined qualitative and quantitative-geostatistical method. Overall, 33 benthic TOC-based provinces were defined and used to process the global distribution pattern of the TOC content in surface sediments in a 1°x1° grid resolution. Regional dependencies of data points within each single province are expressed by modeled semi-variograms. Measured and estimated TOC values show good correlation, emphasizing the reasonable applicability of the method. The accumulation of organic carbon in marine surface sediments is a key parameter in the control of mineralization processes and the material exchange between the sediment and the ocean water. Our approach will help to improve global budgets of nutrient and carbon cycles.

    Stable isotope ratios on planktonic foraminifer N. pachyderma of surface sediments from the Arctic Ocean (Table 1) (1994)

    Description: Planktic foraminifers Neogloboquadrina pachyderma (sin.) from 87 eastern and central Arctic Ocean surface sediment samples were analyzed for stable oxygen and carbon isotope composition. Additional results from 52 stations were taken from the literature. The lateral distribution of delta18O (18O/16O) values in the Arctic Ocean reveals a pattern of roughly parallel, W-E stretching zones in the Eurasian Basin, each ~0.5 per mil wide on the delta18O scale. The low horizontal and vertical temperature variability in the Arctic halocline waters (0-100 m) suggests only little influence of temperature on the oxygen isotope distribution of N. pachyderma (sin.). The zone of maximum delta18O values of up to 3.8 per mil is situated in the southern Nansen Basin and relates to the tongue of saline (〉 33%.) Atlantic waters entering the Arctic Ocean through the Fram Strait. delta18O values decrease both to the Barents Shelf and to the North Pole, in accordance with the decreasing salinities of the halocline waters. In the Nansen Basin, a strong N-S delta18O gradient is in contrast with a relatively low salinity change and suggests contributions from different freshwater sources, i.e. salinity reduction from sea ice meltwater in the south and from light isotope waters (meteoric precipitation and river-runoff) in the northern part of the basin. North of the Gakkel Ridge, delta18O and salinity gradients are in good accordance and suggest less influence of sea ice melting processes. The delta13C (13C/12C) values of N. pachyderma (sin.) from Arctic Ocean surface sediment samples are generally high (0.75-0.95 per mil). Lower values in the southern Eurasian Basin appear to be related to the intrusion of Atlantic waters. The high delta13C values are evidence for well ventilated surface waters. Because the perennial Arctic sea ice cover largely prevents atmosphere-ocean gas exchange, ventilation on the seasonally open shelves must be of major importance. Lack of delta13C gradients along the main routes of the ice drift from the Siberian shelves to the Fram Strait suggests that primary production (i.e. CO2 consumption) does probably not change the CO2 budget of the Arctic Ocean significantly.

    Description: [1] We used planktic foraminiferal assemblages in 70 sediment cores from the tropical and subtropical South Atlantic Ocean (10°N–37°S) to estimate annual mean sea surface temperatures (SSTs) and seasonality for the Last Glacial Maximum with a modified version of the Imbrie-Kipp transfer function method (IKTF) that takes into account the abundance of rare but temperature sensitive species. In contrast to CLIMAP Project Members [1981], the reconstructed SSTs indicate cooler glacial SSTs in the entire tropical/subtropical South Atlantic with strongest cooling in the upwelling region off Namibia (7–10°C) and smallest cooling (1–2°C) in the western subtropical gyre. In the western Atlantic, our data support recent temperature estimates from other proxies. In the upwelling regions in the eastern Atlantic, our data conflict with SST reconstructions from alkenones, which may be due to an environmental preference of the alkenone-producing algae or to an underestimation of foraminiferal SSTs due to anomalous high abundances of N. pachyderma (sinistral).
