Radiolarians in the Sea of Okhotsk
To assess the relationship of radiolarian production, species distribution in water and surface sediment to water-mass characteristics, biological productivity and export... -
Age determination and stable isotope composition of sediment cores from the A...
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... -
Geochemistry of sediments from the mid-oceanic Kolbeinsey Ridge
In order to assess recent submarine volcanic contributions to the sediments from the active Kolbeinsey Ridge, surface samples were analyzed chemically. The contribution of major... -
Sedimentology of the Reykjanes Ridge, Southeast Greenland
Marine records from the Reykjanes Ridge indicate ice sheet variations and abrupt climate changes. One of these records, ice-rafted detritus (IRD), serves as a proxy for iceberg... -
Multi-proxy analyses of sediment cores from the Pakistan continental margin
Late Holocene laminated sediments from a core transect centred in the oxygen minimum zone (OMZ) impinging at the continental slope off Pakistan indicate stable oxygen minimum... -
Varved sediments of the Arabian Sea
The upper Holocene marine section from a kasten core taken from the oxygen minimum zone off Karachi (Pakistan) at water depth 700 m contains continuously laminated sediments... -
Temperature reconstruction of sediment cores from the northeastern Arabian Sea
In order to reconstruct the monsoonal variability during the late Holocene we investigated a complete, annually laminated sediment record from the oxygen minimum zone (OMZ) off... -
Ostracoda in five sediment cores from the Laptev and Kara seas
Fossil ostracods were investigated in five AMS14C-dated cores from different parts of the Laptev and Kara seas. Three cores from the Laptev Sea shelf are located in river... -
Radiogenic isotope record of Arctic Ocean circulation and weathering inputs o...
Lead (Pb), neodymium (Nd), and strontium (Sr) isotopic analyses were carried out on sediment leachates (reflecting the isotope composition of past seawater) and digests of the... -
Organic carbon and biomarker record from the Laptev Sea continental margin
In order to understand the processes controlling organic carbon deposition (i.e., primary productivity vs. terrigenous supply) and their paleoceanographic significance, three... -
Susceptibility of sediment cores of the Laptev Sea
Marine geological investigations were performed across the Laptev Sea continental shelf and slope. Thirty sampling sites were selected covering a depth range of ca 3500 m.... -
High-resolution magnetostratigraphy of sediment cores from the Greenland Sea
High-resolution magnetostratigraphic analysis of three sediment cores from the base of the volcanic seamount Vesteris Banken in the Greenland Basin and one from the Jan Mayen... -
Magnetostratigraphy of sediment cores from the Greenland Sea
High-resolution magnetostratigraphic analysis of three sediment cores from the base of the volcanic seamount Vesteris Banken in the Greenland Basin and one core from the Jan... -
Organic geochemistry on sediment profiles from the Arctic Ocean
During the ARCTIC '91-Expedition with RV 'Polarstern', several Multicorer and Kastenlot-cores were recovered along a profile crossing the eastern part of the Arctic Ocean. The... -
Physical properties and age determination of sediment cores from the Hinlopen...
Integrated interpretation of multi-beam bathymetric, sediment-penetrating acoustic (PARASOUND) and seismic data show a multiple slope failure on the northern European... -
High-resolution organic-geochemical and sedimentological data of sediment cor...
From a high sedimentation rate core, obtained from the Yermak slope (Arctic Ocean), we deduced short-term climatic fluctuations of the last deglaciation lasting from 17,000 to... -
Ostracoda in surface sediments of the Arctic Ocean
Ostracodes were studied from deep Arctic Ocean cores obtained during the Arctic 91 expedition of the Polarstern to the Nansen, Amundsen and Makarov Basins, the Lomonosov Ridge,... -
Sedimentology of three cores from the Laptev Sea continental margin (Arctic O...
Three sediment cores from the Laptev Sea continental margin were investigated for their clay mineralogy by X-ray diffraction to study the fluvial sediment supply since the late... -
Benthic foraminiferal records from two sediment cores from the Arctic Ocean
The benthic foraminiferal record of two sediment cores at 900 and 2500 rn water depth in the marginal Arctic Ocean reflects fluctuations in paleoproductivity, ice sheet extent,... -
Sedimentology of three cores recovered off the northwest of Svalbard
Three cores recovered off the northwest of Svalbard were studied with respect to glacial/interglacial changes of clay and bulk mineralogy, lithology and organic geochemistry....
