“…Even higher primary production is inferred for the Holocene [8,10]. In general, higher productivity during interglacials is characteristic of the Arctic and Subarctic regions [32]. Deposition in the oxygen mini mum zone took place synchronously with the increase in paleoproductivity.…”

Abstract-The analysis of the lithology, grain size distribution, clay minerals, and geochemistry of Upper Pleistocene sediments from the submarine Shirshov Ridge (Bering Sea) showed that the main source area was the Yukon-Tanana terrane of Central Alaska. The sedimentary materials were transported by the Yukon River through Beringia up to the shelf break, where they were entrained by a strong northwestward flowing sea current. The lithological data revealed several pulses of ice rafted debris deposition, roughly synchronous with Heinrich events, and periods of weaker bottom current intensity. Based on the geochemical results, we distinguished intervals of an increase in paleoproductivity and extension of the oxygen minimum zone. The results suggest that there were three stages of deposition driven by glacioeustatic sea level fluctuations and glacial cycles in Alaska.

“…Thus, the zone of modern glacial sedimentation, connected with sea ice and icebergs, integrally occupies about 20 % of the World Ocean surface, i.e., this type of sedimentary process is very important in the ocean both now and in the past (Lisitzin, 1968(Lisitzin, , 1996(Lisitzin, , 2002(Lisitzin, , 2010Powell, 1984;Dowdeswell and Scourse,1990;Stein, 2008;Levitan and Lavrushin, 2009). During of glacial periods it became the major not only on continents but in World Ocean.…”

“…The early Holocene transgression responsible for the formation of the Cheshskaya Bay first terrace, which is elevated up to 6-10 m a.s.l. is correlated with the Pholas transgression in Scandinavia and Kola Peninsula (Arslanov et al 1974;Polyak and Mikhailov 1996;Levitan and Lavrushin 2009). The stillstand or relative sea-level rise correlates with the Holocene trangsression maximum (Tapes) which is dated to 7.0-6.0 kyrs BP in this northern area (Marthinussen 1962;Lavrov and Potapenko 2005).…”

First high-resolution micropaleontologic investigation was carried out for bottom sediments of the Cheshskaya Bay (SE Barents Sea) and marine beds exposed in abrasive terrace along the eastern coast of the Kanin Peninsula. Sediments from 2 gravity cores and a 7.5-m thick terrace section were analyzed for pollen and non-pollen palynomorphs (NPP), including spores, freshwater green algae and cysts of marine dinoflagellates. The age of the sediments was constrained by the reference to the regional sea-level history from the earliest Holocene to present, thus the pollen records reveal the environmental history for the last ca. 10.0 ka. Sparse treeless vegetation with dwarf Betula and halophytic inhabitants of seaside watts (cereals, wormwood and sedges) indicating arctic desert environment with colder and drier than present climate dominated the Cheshskaya Bay coast during the early Preboreal period. Gradual advance of shrubby-birch and piny forest-tundra with alder communities along river valleys resulted from significant climate amelioration which concurred with the Pholas inundation since the Boreal period. Postdated expansion of tree-birch inland the Kanin Peninsula and firry-birch light-forests along the Cheshskaya Bay coast marked the Holocene regional climate optimum. Re-establishment of the dwarf-birch and piny forest tundra signalized vegetation feedback to the cooling since the end of Atlantic period.
