Four sediment cores recovered from 1000 to 2500 m water depth in the Arctic Ocean, tracing the inflowing Atlantic water from Fram Strait, Yermak Plateau, northern Barents Sea continental slope as far as the Laptev Sea, ...

Underway (U)CTD data were collected during a 2013 (22. August – 21. September) expedition to the Arctic Ocean aboard the RV Viktor Buinitsky as part of the German-Russian BMBF-funded project Transdrift (The transpolar ...

These data are laboratory results for carbon characteristics (TOC, TC, TN, C/N ratio, stable carbon isotope ratio, radiocarbon ages from bulk organic material), sediment characteristics (mass specific magnetic susceptibility ...

Long-chain diols have been detected in a wide range of environments and have been used to reconstruct past environmental changes, however only a few long-term records exist to date. Here we reconstructed past environmental ...

To study inorganic nitrogen uptake rates by microplankton in the Black Sea the first 15N-experiments were carried out in August-September 1990 and in November 1991. In surface waters nitrate uptake rates varied from 5.7 ...

Relative to the past 2,000 years, the Arctic region has warmed significantly over the past few decades. However, the evolution of Arctic temperatures during the rest of the Holocene is less clear. Proxy reconstructions, ...

This PhD thesis focused on the analysis and application of microbial membrane lipids as biomarkers in marine sediments. Existing protocols for lipid extraction from marine sediments and biomass were modified. In addition, ...
