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 ...
Depositional environment of the Laptev Sea (Arctic Siberia) during the Holocene.

Bauch, Henning A; Kassens, Heidemarie; Erlenkeuser, Helmut; Grootes, Pieter Meiert; Thiede, Jörn (PANGAEA, 1999-01-26)

The Holocene depositional setting of the Laptev Sea was studied using three marine sediment cores from water depths between 77 and 46 m. Based on sedimentary parameters (TOC content, delta13Corg, sedimentation rates) ...
History of freshwater runoff across the Laptev Sea (Arctic) during the last degaciation.

Spielhagen, Robert F; Siegert, Christine; Erlenkeuser, Helmut (PANGAEA, 2005-05-19)

Sediment core PS2458 from the Laptev Sea continental margin (983-m water depth) stems from a position close to the paleoriver mouth of Lena and Yana rivers. It was dated by AMS-14C and analyzed in high resolution for oxygen ...
Holocene variability of bottom water hydrography on the Kara Sea shelf (Siberia) depicted in multiple single-valve analyses of stable isotopes in ostracods.

Simstich, Johannes; Stanovoy, Vladimir V; Bauch, Dorothea; Erlenkeuser, Helmut; Spielhagen, Robert F (PANGAEA, 2010-12-01)

Ostracods secrete their valve calcite within a few hours or days, therefore, its isotopic composition records ambient environmental conditions of only a short time span. Hydrographic changes between the calcification of ...
Mid Holocene origin of the sea surface salinity low in the Subarctic North Pacific.

Sarnthein, Michael; Gebhardt, Holger; Kiefer, Thorsten; Kucera, Michal; Cook, M; Erlenkeuser, Helmut (PANGAEA, 2004-06-11)

IMAGES core MD01-2416 (51°N, 168°E) provides the first centennial-scale multiproxy record of Holocene variation in North Pacific sea-surface temperature (SST), salinity, and biogenic productivity. Our results reveal a ...
Modern and Holocene hydrographic characteristics of the shallow Kara Sea shelf (Siberia) as reflected by stable isotopes of bivalves and benthic foraminifera.

Spielhagen, Robert F; Simstich, Johannes; Erlenkeuser, Helmut; Stanovoy, Vladimir V (PANGAEA, 2005-07-17)

River discharge of Ob and Yenisei to the Kara Sea is highly variable on seasonal and interannual time scales. River water dominates the shallow bottom water near the river mouths, making it warmer and less saline but ...
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 ...
