The East Siberian Sea (ESS) is one of the least studied seas in terms ostracod fauna. Ostracods are sensitive organisms to environmental changes, and detailed information on their ecology still required. To fill this knowledge gap, we 33 meiobenthic dredge samples collected from western part ESS Chaun Bay together with 17 grab taken eastern sea. Quantitative analyses assemblages demonstrate that river-influenced inhabited by low diverse impoverished fauna consisting taxa which able adapt...
We present a complex study on mineralogical, U/Th dating, isotopic and geochemical characteristics of Pleistocene glendonites (calcite pseupomorphs after ikaite) from the outcrops Bol’shaya Bakakhnya valley, Eastern Taimyr, Russia. Based dating (37 ± 7 ka) we propose that host sediments were formed during Karginsky interstadial (22—50 – this data corresponds well with published ages foraminifers wood fragments deposits Taimyr. The main factors leading to ikaite crystallization was presence...
The palynological method was used to study a 455 cm thick marine sediment sequence, which overlies the Moscovian moraine in Bychye-2 section on Pyoza River (Arkhangel’sk region). pollen records obtained allowed us make palynozonal subdivision of and trace plant cover transformations that occurred northeastern White Sea region during Boreal transgression. When comparing established local palynozones with regional subdivisions reference sections Bychye-1, located 5 km upstream from site, Peski...
Detailed multiproxy (lithology, micropaleontology, palynology) study of a 455 cm thick marine sediment sequence overlying the Moscovian till exposed in Bychye-2 section on Pyoza River allowed for reconstructing past environmental changes during Boreal transgression. Stratigraphic subdivision is based succession local palynological zones that were correlated with previously established regional zones. The latter are constrained basis correlation West European Marine sediments accumulated from...
Reconstructing interglacial marine environments helps us understand the climate change mechanisms of past. To contribute to this body knowledge, we studied a high-resolution 455 cm-thick sediment sequence Boreal (Eemian) beds directly overlying Moscovian (Saalian) moraine in Bychye-2 section on Pyoza River. We analyzed lithological and microfossil (foraminifers, ostracods, pollen, aquatic palynomorphs) variations at site. Stratigraphical zonation is based local well-established regional...
The basal part of Ushchemenskii section from the Zimnii coast White Sea represents marine clayey sediments Boreal transgression Mikulinian (Late Pleistocene) age. For first time, benthic foraminifers, ostracods and aquatic palynomorphs are reported for this area. Data on microfauna were used paleoecological analysis to reconstruct a coastal basin with sea-ice cover, water depths > 50 m, high sedimentation rates possible inflow warm masses North Atlantic.
