Description
Summary:Measured stable isotopes of N. pachyderma & C. neoteretis (without vital effect correction).The sampled sediment record PS93/025, consisting of the Giant box core (GKG) PS93/025-1 (80.481°N, 8.487°W, 291.3 m water depth) and the Kastenlot core (KAL) PS93/025-2 (80.482°N, 8.490°W, 290.2 m water depth), was obtained during the expedition PS93.1 (2015) (Stein, 2016) of RV Polarstern on the outermost NE Greenland shelf in the western Fram Strait.The presented data covers the last ca. 10.6 ka.For stable oxygen and carbon isotope analyses, ca. 30 specimens of N. pachyderma and the benthic foraminifer species Cassidulina neoteretis from the 100–250 μm fraction were used. The measurement interval is 1 cm for both species between 264 and 93 cm, whereas it shifts to ca. 2 cm for the benthic species and 5 cm for the planktic species between 93 cm and 0.5 cm, due to low numbers of specimens. All analyses were carried out on a MAT 253 mass spectrometer system and a KIEL IV Carbonate Preparation Device at the GEOMAR ...
