The data set of the marine sediment core PS97/72-1 from the Bransfield Strait, Antarctic Peninsula, contains data from analyses of a 1012 cm core covering the age from recent to 13.8 ka BP. The piston core was retrieved 2016 during R/V Polarstern cruise PS97. The purpose of this data was a study for the reconstruction of Deglacial and Holocene sea ice and climate dynamics in the Bransfield Strait, Northern Antarctic Peninsula, which was published in Climate of the Past. Dataset 1 contains details of the radiocarbon ages. Dataset 2 are the geochemical bulk parameters including sedimentation rate, total organic carbon, biogenic opal, C/N ration, d13C of organic carbon, branched and isoprenoid tetraether index BIT and ice rafted debris. Dataset 3 is information on biomarkers with highly branched isoprenoids diene and triene (IPSO25), the phytoplankton biomarker IPSO25 index, d13C of IPSO25, branched and isoprenoid tetraether index BIT, sub-surface ocean temperature (based on branched GDGTs), diatom derived sea ...
