The coarse fraction content and the oxygen and carbon isotopic compositions of two morphotyes of planktic foraminifers Neogloboquadrina pachyderma were determined from sediment samples obtained from sediment core PS93/031-5. The age model is based on 9 radiocarbon datings obtained on ~2000 specimens of N. pachyderma each.Grain size measurements occurred in May-July 2017. Stable isotope measurements were performed in August 2018 to February 2019. According to radiocarbon datings (https://doi.pangaea.de/10.1594/PANGAEA.930416) converted to calibrated years with the program Calib 8.2 (http://calib.org/calib/), using the IntCal20 data set and applying a reservoir correction of 550 years), the core covers the interval of 3,750-23,230 years before present, with the hiatus covering the interval 12,660-18,550 years.Sediment core PS93/031-5 was obtained during RV POLARSTERN expedition PS93.1 in the northwestern Fram Strait on the Northeast Greenland continental margin from 2,135 m water depth.The data were collected ...
