Planktic and benthic stable oxygen and carbon isotope, IRD, planktic foraminifera data and sand fraction content of sediment core PS1904-2 ...
Sediment core PS1904 reveals continuous records of planktic and benthic foraminiferal stable isotopes (d18O/d13C) from the north-eastern Greenland continental margin. The data show good comparability with other records from the Nordic Seas, allowing the stratigraphic range of PS1904 to be dated to M...
