Publikováno v: Ocean Science, Vol 14, Pp 87-103 (2018)
The East Siberian Arctic Shelf (ESAS) is the broadest and shallowest continental shelf in the world. It is characterized by both the highest rate of coastal erosion in the world and a large riverine input of terrigenous dissolved organic matter (D

Carbon transport by the Lena River from its headwaters to the Arctic Ocean, with emphasis on fluvial input of terrestrial particulate organic carbon vs. carbon transport by coastal erosion
Autor: I. P. Semiletov, I. I. Pipko, N. E. Shakhova, O. V. Dudarev, S. P. Pugach, A. N. Charkin, C. P. McRoy, D. Kosmach, Ö. Gustafsson
Publikováno v: Biogeosciences, Vol 8, Iss 9, Pp 2407-2426 (2011)
The Lena River integrates biogeochemical signals from its vast drainage basin, and the integrated signal reaches far out over the Arctic Ocean. Transformation of riverine organic carbon (OC) into mineral carbon, and mineral carbon into the organic fo

Interannual variability of air-sea CO2 fluxes and carbon system in the East Siberian Sea
Autor: I. Wåhlström, S. P. Pugach, I. P. Semiletov, I. I. Pipko, L. G. Anderson
Publikováno v: Biogeosciences, Vol 8, Iss 7, Pp 1987-2007 (2011)
Over the past couple of decades it has become apparent that air-land-sea interactions in the Arctic have a substantial impact on the composition of the overlying atmosphere (ACIA, 2004). The Arctic Ocean is small (only ~4 % of the total World Ocean),

Publikováno v: Âderna Fìzika ta Energetika, Vol 22, Iss 1, Pp 42-47 (2021)
The standard surveillance programs of WWER reactors do not allow to measure the surveillance specimens irradiation conditions with the required accuracy. Therefore, the special methodology for the determination of the surveillance specimens irradiati
