Geo-Marine Letters, 22(2), 51-59, https://doi.org/10.1007/s00367-002-0097-7

    Description: Records of glaciomarine deposition recovered from the West Antarctic continental margin in the Amundsen Sea allow the reconstruction of the behaviour of the West Antarctic Ice Sheet (WAIS) in response to the natural climatic changes of the last 1.8 million years. Contents of gravel-sized and lithogenic components represent the input and redeposition of glaciogenic debris, whereas variations in the proportions of the calcareous sediment fraction reflect palaeoproductivity changes. All proxies, which are regarded as sensitive to a WAIS collapse, changed markedly during the global climatic cycles, but do not confirm a complete disintegration of the WAIS during the Pleistocene.

Paleoceanography, 18(3), 1065, https://doi.org/10.1029/2002PA000774

    Description: The response of the tropical ocean to global climate change and the extent of sea ice in the glacial nordic seas belong to the great controversies in paleoclimatology. Our new reconstruction of peak glacial sea surface temperatures (SSTs) in the Atlantic is based on census counts of planktic foraminifera, using the Maximum Similarity Technique Version 28 (SIMMAX-28) modern analog technique with 947 modern analog samples and 119 well-dated sediment cores. Our study compares two slightly different scenarios of the Last Glacial Maximum (LGM), the Environmental Processes of the Ice Age: Land, Oceans, Glaciers (EPILOG), and Glacial Atlantic Ocean Mapping (GLAMAP 2000) time slices. The comparison shows that the maximum LGM cooling in the Southern Hemisphere slightly preceeded that in the north. In both time slices sea ice was restricted to the north western margin of the nordic seas during glacial northern summer, while the central and eastern parts were ice-free. During northern glacial winter, sea ice advanced to the south of Iceland and Faeroe. In the central northern North Atlantic an anticyclonic gyre formed between 45° and 60°N, with a cool water mass centered west of Ireland, where glacial cooling reached a maximum of 〉12°C. In the subtropical ocean gyres the new reconstruction supports the glacial-to-interglacial stability of SST as shown by CLIMAP Project Members (CLIMAP) [1981]. The zonal belt of minimum SST seasonality between 2° and 6°N suggests that the LGM caloric equator occupied the same latitude as today. In contrast to the CLIMAP reconstruction, the glacial cooling of the tropical east Atlantic upwelling belt reached up to 6°–8°C during Northern Hemisphere summer. Differences between these SIMMAX-based and published U37[k]- and Mg/Ca-based equatorial SST records are ascribed to strong SST seasonalities and SST signals that were produced by different planktic species groups during different seasons.

    Publication Date: 2024-07-01
    Description: Composition and accumulation rates of organic carbon in Holocene sediments provided data to calculate an organic carbon budget for the Laptev Sea continental margin. Mean Holocene accumulation rates in the inner Laptev Sea vary between 0.14 and 2.7 g C cm**2/ky; maximum values occur close to the Lena River delta. Seawards, the mean accumulation rates decrease from 0.43 to 0.02 g C cm**2/ky. The organic matter is predominantly of terrigenous origin. About 0.9*10**6 t/year of organic carbon are buried in the Laptev Sea, and 0.25*10**6 t/year on the continental slope. Between about 8.5 and 9 ka, major changes in supply of terrigenous and marine organic carbon occur, related to changes in coastal erosion, Siberian river discharge, and/or Atlantic water inflow along the Eurasian continental margin.

International Journal of Earth Sciences, 89(3), 578-591, https://doi.org/10.1007/s005310000111
    Publication Date: 2024-07-01
    Description: In order to reconstruct the depositional environment from the Laptev Sea continental slope and shelf during the past ~15,000 years BP maceral analysis was carried out on two sediment cores (PS2458-4, PS2725-5) and compared with organic-geochemical parameters. During the transition from the Last Glacial to the Holocene the environment of the Laptev Sea shelf was controlled by the post-glacial sea level rise, variations in river discharge, surface-water productivity, and Atlantic-water inflow along the Eurasian continental margin. Based on our results, we identify the following significant changes of the environment: (a) at approximately 13,500 years BP the first step of deglaciation (Termination 1a) is documented by the deposition of marine and fresh-water organic matter; (b) at approximately 10,400 years BP the first post-glacial influence of Atlantic-water inflow along the Eastern Laptev Sea continental margin is indicated by an increase in marine organic matter; (c) at the beginning of the Holocene an increased fluvial supply is documented by an increase in fresh-water alginite; and (d) since ~9500-8000 years BP modern marine conditions are established at the Laptev Sea continental margin as documented in increased amounts of marine macerals, biomarkers (dinosterol, brassicasterol, short-chain fatty acids), and dinoflagellate cysts.

International Journal of Earth Sciences, 89(3), 563-568, https://doi.org/10.1007/s005310000128
    Publication Date: 2024-07-01
    Description: Stable carbon isotope ratios in the organic fraction of surface sediments from the Laptev Sea shelf were analyzed in order to study the modern distribution pattern of terrestrial organic matter. The delta13Corg signature of the surface sediments range from -26.6 per mil near the coastal margin to -22.8 per mil in the north towards the outer shelf. Characterizing the possible sources of organic matter by their delta13Corg signature reveals that the terrestrial influence reaches further north in the eastern than in the western Laptev Sea. Downcore records of the delta13Corg, measured on three AMS 14C-dated cores from water depths between 46 and 77 m, specify the spatial and temporal changes in the deposition of terrestrial organic matter on the Laptev Sea shelf during the past 12.7 ka. The major depositional changes of terrestrial organic matter occurred between 11 and 7 ka and comprised the main phase of the southward retreat of the coastline and of the river depocenters due to the postglacial sea level rise.

    Description: Three long sediment cores from the Makarov Basin have been subjected to detailed paleomagnetic and rock magnetic analyses. Investigated sediments are dominated by normal polarity including short reversal excursions, indicating that most of the sediments are of Brunhes age. In general, the recovered sediments show only low to moderate variability in concentration and grain size of the remanence-carrying minerals. Estimations of relative paleointensity variations yielded a well-documented succession of pronounced lows and highs that could be correlated to published reference curves. However, together with five accelerator mass spectrometry 14C ages and an incomplete 10Be record, still two different interpretations of the paleomagnetic data are possible, with long-term sedimentation rates of either 1.3 or 4 cm/kyr. However, both models implicate highly variable sedimentation rates of up to 10 cm/kyr, and abrupt changes in rock magnetic parameters might even indicate several hiatuses.

    Description: Die im Rahmen des zweijährigen Forschungsprojekts über paläomagnetisch-sedimentologische Analysen sedimentärer Zyklen in der Weddell See und ihre stratigraphische Interpretation durchgeführten Arbeiten lieferten Ergebnisse zur Geschichte glaziomariner Sedimentationsprozesse am antarktischen Kontinentalrand. So konnte für ein Kernprofil mit einer außergewöhnlichen Terassenstruktur eine fazielle Gliederung und stratigraphische Einordnung erreicht werden, die auch auf größere Areale in der Weddell See anwendbar sind. Aufgrund der stratigraphischen Randbedingungen konnten die gewonnenen paläo- und gesteinsmagnetischen Messungen in eine Altersstruktur integriert und zusammen mit den sedimentologischen Parametern im Hinblick auf lokale und regionale Umweltveränderungen interpretiert werden. Insbesondere die gesteinsmagnetischen Analysen haben gezeigt, daß die magnetische Kornfraktion als accessorischer Bestandteil im Gesamtsediment dennoch an die Sortierungsprozesse des terrigenen Sedimenteintrags gekoppelt ist. Die ungewöhnlich deutlichen Variationen korngrößenabhängiger Parameter zeigten weiterhin, daß in Verbindung mit einer hochauflösenden Stratigraphie die magnetische Detailanalyse und ein besseres Verständnis der Sedimentationsprozesse in der Nähe der Schelfeiskante und speziell bei Meeresspiegeltiefständen die Möglichkeit eröffnen, unmittelbar Aussagen über die Bewegungen der Schelfeise und die Qualität der Meereisbedeckungen zu machen. Die gezielte Fortsetzung dieser Arbeiten in anderen Arealen am antarktischen Kontinentalrand ist daher wünschenswert. Die verwendeten Verfahren lassen sich mit den derzeit verfügbaren Instrumenten noch erweitern und versprechen durch die sehr sensitive Methodik detaillierte Aussagen zu glaziomarinen Sedimentationsprozessen.
