Radiocarbon datings from sediment core PS93/031-5 (NW Fram Strait)
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. Sediment slices of approx. 5 mm thickness were taken from sediment core PS93/031-5 every 0.5 cm (~30 g dry sediment per...
