Benthic foraminifera in the marginal Arctic Ocean ...
Analyses of benthic foraminifera in sediment cores taken at about 1000 m water depth at the Yermak Plateau and the Barents Sea slope, adjacent to the position of the ice-sheet edge during the Last Glacial Maximum, show that paleoproductivity was reduced to about a third of its present level during p...
