Geochemistry of the Laptev and East Siberian seas sediments with emphasis on rare-earth elements: Application for sediment sources and paleoceanography

Sattarova V.V., Astakhov A.S., Aksentov K.I., Shi Xuefa, Hu Limin, Liu Yanguang, Polyakov D.M., Alatortsev A.V., Kolesnik O.N.
Deciphering the origin of sedimentary material in the Arctic can contribute to a deeper understanding of modern transport and sedimentation processes. Here, the application of rare earth elements (REEs) is particularly promising, as they can serve as indicators of sources as well as chemical and...

Mercury geochemistry of marine sediments from the eastern Laptev Sea

Kim D.V., Sattarova V.V., Aksentov K.I., Lopatnikov E.A., Ivanov M.V., Alatortsev A.V., Melgunov M.S.
Twenty-seven sediment samples from the eastern Laptev Sea were analyzed for mercury and total organic carbon as well as grain-size distribution. The average total mercury (THg) concentrations in sediments are 29±14 µg kg-1. A significant correlation of THg content with total organic carbon and...

Geochemistry aspects of modern mercury accumulation in bottom sediments from the south-western Chukchi Sea

Kim D.V., Aksentov K.I., Astakhov A.S., Sattarova V.V., Ivanov M.V., Alatorsev A.V., Obrezkova M.S., Selutin S.A.
Mercury (Hg) having a high migration capacity reach the Arctic region via the atmosphere. The absorbers for Hg are sea bottom sediments. Sedimentation in the Chukchi Sea occurs under the influence of highly productive Pacific waters entering through the Bering Strait and the inflow of a...
