Distribution Patterns of Calcareous Foraminifers in Arctic Ocean Sediments

  author={N. Belyaeva and T. A. Khusid},
The distribution of benthic and planktic foraminifers in Arctic Canada Basin sediments was studied quantitatively. The large number of dead tests of these foraminifers (at low productivity of living organisms), excellent test preservation, and significant predominance of planktic forms indicate the absence of dissolution and conditions favorable for accumulation of calcareous foraminiferal tests at the bottom of the Arctic Ocean. 
Contrasting glacial/interglacial regimes in the western Arctic Ocean as exemplified by a sedimentary record from the Mendeleev Ridge
Distinct cyclicity in lithology and microfaunal distribution in sediment cores from the Mendeleev Ridge in the western Arctic Ocean (water depths ca. 1.5 km) reflects contrasting glacial/interglacialExpand
The saturation of calcite and aragonite in the Arctic Ocean
Abstract We report on the chemical saturation of CaCO 3 in the waters of the Arctic Ocean calculated from total alkalinity ( A T ) and total dissolved inorganic carbon (C T ). Data based on fourExpand
Ocean acidification and biologically induced seasonality of carbonate mineral saturation states in the western Arctic Ocean
Calcium carbonate (CaCO3) mineral saturation states for aragonite (?aragonite) and calcite (?calcite) are calculated for waters of the Chukchi Sea shelf and Canada Basin of the western Arctic OceanExpand


Rates of sedimentation in the Arctic ocean
Abstract The sedimentation rate in the Arctic deep-sea over the last 150,000 years has undergone no significant changes. Based on both radiocarbon and uranium series isotope analyses, the depositionExpand
Arctic ocean quaternary microfauna and its relation to paleoclimatology
Abstract Examination of 350 samples from seven deep-sea cores raised in the Arctic Ocean Basin indicates that: (1) faunal variations coincide with changes in sediment characteristics suggesting thatExpand
