Benthic and planktic foraminiferal data of sediment core PS93/016


This dataset shows benthic and planktic foraminiferal data, planktic foraminiferal fragmentation and coarse fraction values. The sampled sediment record PS93/016, consisting of the Giant box core (GKG) PS93/016-4 (81.217°N, 7.341°W, 1549.8 m water depth) and the Kastenlot core (KAL) PS93/016-6 (81.217°N, 7.341°W, 1548.3 m water depth), was obtained during the expedition PS93.1 (2015) (Stein, 2016) of RV Polarstern at the NE Greenland continental margin in the northwestern Fram Strait. The presented data covers the last ca. 195 ka. In representative splits of the 100-250 µm size fraction, planktic and benthic foraminifers were determined and counted. Fragmentation of planktic foraminifers was calculated by counting fragments which were no more determinable to species level. Thereby, the equation from Pfuhl and Shackleton (2004) was used which includes a fragment-divisor of 3. Aim of the study was to reconstruct glacial advance and retreat, changes in sea-ice and export of freshwater in the western Fram Strait and, to a certain extent, in the Arctic Ocean.
