Holocene biomarker (HBIs) and stable isotope data from 80N

Biomarker (HBIs) and stable isotope data (d18O, d13C) from sediment cores HH15-06GC and JR142-11GC. The data originates from two marine sediment cores northeast of Svalbard. Core JR142-11GC was obtained using a gravity corer during a cruise with RSS “James Clark Ross” carried out by British Antarctic Survey in 2006. Core HH15-06GC was also obtained using a gravity corer during a cruise with RV “Helmer Hanssen” carried out by University Centre in Svalbard 2015. The research aims were 1) to investigate cryosphere-ocean linkages during the final decline of the Barents Sea Ice Sheet (BSIS) which may serve as an analogue of modern West Antarctic Ice Sheet (WAIS), and 2) obtain baseline values for natural fluctuations of ocean temperature and sea-ice evolution in northern Barents Sea – Svalbard region.
