Biogenic barium in surface sediments of the European Nordic Seas.

Pirrung, Michael (PANGAEA, 2008-03-14)

Barium in marine terrigenous surface sediments of the European Nordic Seas is analysed to evaluate its potential as palaeoproductivity proxy. Biogenic Ba is calculated from Ba and Al data using a conventional approach. For ...
Changes in the deposition of terrestrial organic matter on the Laptev Sea shelf during the Holocene: evidence from stable carbon isotopes.

Müller-Lupp, Thomas; Bauch, Henning A; Erlenkeuser, Helmut; Hefter, Jens; Kassens, Heidemarie; Thiede, Jörn (PANGAEA, 2000-01-29)

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 ...
Clay mineral distribution in surface sediments of the Laptev Sea: indicator for sediment provinces, dynamics and sources.

Rossak, B T (PANGAEA, 2000-03-09)
Clay-mineral distribution in surface sediments of the Eurasian Arctic Ocean and continental margin as indicator for source areas and transport pathways - a synthesis.

Wahsner, Monika; Müller, Claudia; Stein, Ruediger; Ivanov, Gennadiy I; Levitan, Mikhail A; Shelekhova, E S; Tarasov, Gennadiy A (PANGAEA, 1999-09-18)

Clay-mineral distributions in the Arctic Ocean and the adjacent Eurasian shelf areas are discussed to identify source areas and transport pathways of terrigenous material in the Arctic Ocean. The main clay minerals in ...
Distribution of aquatic palynomorphs in surface sediments from the Laptev Sea, Eastern Arctic Ocean.

Kunz-Pirrung, Martina (PANGAEA, 2000-02-24)
Distribution of magnetic susceptibility on the Eurasian shelf and continental slope - implications for source areas of magnetic minerals.

Niessen, Frank; Weiel, Dominik (PANGAEA, 2000-03-30)
Magnetic susceptibility and ice-rafted debris in surface sediments of the Nordic Seas: implications for isotope stage 3 oscillations.

Pirrung, Michael; Fütterer, Dieter K; Grobe, Hannes; Matthiessen, Jens; Niessen, Frank (PANGAEA, 2002-01-22)

Magnetic susceptibility and ice-rafted debris of surface sediments in the Nordic Seas were investigated to reconstruct source areas and recent transport pathways of magnetic minerals. From the distribution of magnetic ...
Modern organic carbon deposition in the Laptev Sea and the adjacent continental slope: surface water productivity vs. terrigenous input.

Fahl, Kirsten; Stein, Ruediger (PANGAEA, 1997-09-25)

Sediment samples from the Laptev Sea, taken during the 1993 RV Polarstern expedition ARK IX/4 and the RV Ivan Kireyev expedition TRANSDRIFT I, were investigated for the amount and composition of their organic carbon ...
Organic-carbon and carbonate distribution in surface sediments from the eastern central Arctic Ocean and the Eurasian continental margin: sources and pathways.

Stein, Ruediger (PANGAEA, 2000-11-06)
Particulate organic matter in surface sediments of the Laptev Sea (Arctic Ocean): application of maceral analysis as organic-carbon-source indicator.

Boucsein, Bettina; Stein, Ruediger (PANGAEA, 1999-07-06)

Surface sediments from the Laptev Sea and adjacent continental slope were studied for their composition of particulate organic matter (OM) by means of maceral analysis. The composition of macerals in sediments gives ...
Russian-German Cooperation: The Transdrift I Expedition to the Laptev Sea.

Kassens, Heidemarie; Karpiy, Valeriy Y (PANGAEA, 1994-07-07)

The TRANSDRIFT l expedition was part of the joint Russian-German ARCTIC '93 Expedition. During this campaign in the northern Laptev Sea the interdisciplinary research programs of the R/V Polarstern of the Alfred Wegener ...
Short- and long-term environmental changes in the Laptev Sea (Siberian Arctic) during the Holocene (Kurz- und langfristige Umweltveränderungen in der Laptev-See (sibirische Arktis ) während des Holozäns).

Müller-Lupp, Thomas (PANGAEA, 2002-08-16)
Sources and pathways of organic carbon in the modern Laptev Sea (Arctic Ocean): implications from biological, geochemical and geological data.

Fahl, Kirsten; Cremer, Holger; Erlenkeuser, Helmut; Hanssen, Hinrich; Hölemann, Jens A; Kassens, Heidemarie; Knickmeier, Karin; Kosobokova, Ksenia N; Kunz-Pirrung, Martina; Lindemann, Frank; Markhaseva, Elena; Lischka, Silke; Petryashov, Victor; Piepenburg, Dieter; Schmid, Michael K; Spindler, Michael; Stein, Ruediger; Tuschling, Kirsten (PANGAEA, 2001-10-13)

During the past six years organic geochemical, micropaleontological, and sedimentological investigations were carried out within the framework of the multidisciplinary bilateral German-Russian research project ''System ...
Spatial distribution of diatom surface sediment assemblages on the Laptev Sea shelf (Russian Arctic).

Cremer, Holger (PANGAEA, 2000-03-07)
