Benthic foraminiferal records from two sediment cores from the Arctic Ocean ...
The benthic foraminiferal record of two sediment cores at 900 and 2500 rn water depth in the marginal Arctic Ocean reflects fluctuations in paleoproductivity, ice sheet extent, and Atlantic water inflow. Highest paleoproductivity is observed in interglacial periods, and at the termination of interst...
