Supporting data for \"Changes in planktic foraminiferal distribution, productivity, and preservation in the Barents Sea during the last three millennia\"

Paleoproduction changes in the northern and southern Barents Sea based on changes of abundance (absolute and relative) of planktic foraminifers and stable isotopes. Data of total and organic carbon and calcium carbonate content in the sediment was measured. The age-depth model from sediment cores was built based on a combination of lead 210 and carbon 14.
