Evolution of subsea permafrost landscapes in Arctic Siberia since the Late Pleistocene: a synoptic insight from acoustic data of the Laptev Sea
Using high-resolution seismic data, this study aims at investigating the evolution and morphological diversity of subsea permafrost features on the eastern Laptev Sea shelf, Arctic Siberia. Several seismic fac...

Late Pleistocene-Holocene events on the continental slope of the Laptev Sea: Evidence from benthic and planktonic foraminiferal assemblages
This work is dedicated to the study of benthic and planktonic foraminifers and is a contribution to the multidisciplinary investigations of Core PS51/154-11 from the Laptev Sea. The paleoecological analysis of...

Migrations of the North Atlantic Polar front during the last 300 ka: Evidence from planktic foraminiferal data
The main migrations of the Polar front (PF) during the last 300 ka were identified using planktic foraminiferal census data and derived from them sea surface paleotemperature (SST) estimates in two synchronize...

Deep Arctic Ocean warming during the last glacial cycle
In the Arctic Ocean, a salinity gradient separates a shallow layer of cold, relatively fresh water from the warmer, saltier Atlantic water below. A reconstruction of intermediate water temperatures in the Arct...

Reconstruction of deep-water conditions in the North Atlantic during MIS 9 based on benthic foraminiferal assemblages
Marine isotope stage (MIS) 9 is one of the least investigated Pleistocene interglaciations. The present study describes reconstructions of deep-water conditions during this time interval based on benthic foram...

Arctic quaternary ostracods and their use in paleoreconstructions
The paper deals with original and published data on fossil ostracodal assemblages from the Eurasian Arctic Kara, Laptev and Chuckchi seas. As a whole, six ecologically different assemblages were distinguished ...

Changes in the Lena River runoff during the Holocene
The spatial and temporal changes in the Lena River runoff over the last 9 thousand years are reconstructed through studying the freshwater microfossils in sediment cores obtained from the Laptev Sea inner shel...

Hydrological changes in the Laptev Sea during the Holocene inferred from the studies of aquatic palynomorphs
Based on the study of aquatic palynomorph assemblages in two Holocene sediment cores obtained from the eastern Laptev Sea shelf, the main stages in the postglacial transgression are reconstructed for the last ...

Palaeoceanographic implications of genetic variation in living North Atlantic Neogloboquadrina pachyderma
The shells of the planktonic foraminifer Neogloboquadrina pachyderma have become a classical tool for reconstructing glacial–interglacial climate conditions in the North Atlantic Ocean1,2,3. Palaeoceanographers u...

Changes in the deposition of terrestrial organic matter on the Laptev Sea shelf during the Holocene: evidence from stable carbon isotopes
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 δ13Corg sign...

Glacial–interglacial records of the reflectance of sediments from the Norwegian–Greenland–Iceland Sea (Nordic seas)
The reflectance of sediments (gray level) were measured on 11 sediment cores from the Norwegian–Greenland–Iceland Sea (Nordic seas). The analyzed time interval covers the past five glacial–interglacial cycles...

Distribution of Pollen and Spores in Surface Sediments of the Laptev Sea
The palynological content of Laptev Sea surface sediments were studied. The pollen-spore spectra in these recent sediments are characterized by a predominance of coniferous pollen and moss spores. The pollen h...

Planktic Foraminifera in Holocene Sediments from the Laptev Sea and the Central Arctic Ocean: Species Distribution and Paleobiogeographical Implication
Two sediment cores, one from the Siberian Laptev Sea shelf and another from the central Arctic Ocean were investigated with respect to the temporal distribution of planktic foraminifera as well as the species ...
