Lake Billyakh in the Verkhoyansk Mountains provides a lacustrine sediment record of the last 50 ka, which was studied by a palaeolimnological multi-proxy approach on the basis of sedimentological, geochemical, and ...

In this thesis it is shown that the cosmogenic radionuclide 10Be proved to be a sensitive stratigraphic tool for sediment cores from the Arctic Ocean with low or negligible content of biogenic carbonate, impeding a reliable ...

The overarching goal of the Yamal portion of the Greening of the Arctic project is to examine how the terrain and anthropogenic factors of reindeer herding and resource development combined with the climate variations on ...

This data collection contains surface temperature, salinity and ice coverage as well as zooplankton abundance measured on multinet samples during POLARSTERN cruise ARK-IX/4 to the Laptev Sea and Arctic Ocean in 1993.

The large amounts of soil organic matter (SOM) in permafrost-affected soils are prone to increased microbial decomposition in a warming climate. The environmental parameters regulating the production of carbon dioxide (CO2) ...

Within the generally oligotroph Arctic marine environment river outlets are favoured by many planktonic and benthic organisms due to their high input of organic carbon. The retention of pelagic larvae within nursery grounds ...

Although the climate development over the Holocene in the Northern Hemisphere is well known, palaeolimnological climate reconstructions reveal spatiotemporal variability in northern Eurasia. Here we present a multi-proxy ...

Within the scope of Russian-German palaeoenvironmental research, Two-Yurts Lake (TYL, Dvuh-Yurtochnoe in Russian) was chosen as the main scientific target area to decipher Holocene climate variability on Kamchatka. The 5x2 ...

The processes of formation of iron-manganese nodules and crusts have been studied on an example of the Eningi-Lampi lake, Central Karelia, where the relationships between the source of the ore, sedimentary materials and ...

Fifteen iron oxide accumulations from the bottoms of two Finnish lakes ("lake ores") were found to contain as much as 50% Fe. Differential X-ray powder diffraction and selective dissolution by oxalate showed that the samples ...
