Here we present sedimentological, micropalaeontological, inorganic and organic geochemical, palaeomagnetic, geochronological as well as X-ray computed tomography (CT) data obtained from successional drill cores 9R and 10R at MARUM-MeBo70 Site PS104_20-2 (73.57°S, 107.09°W; 946 m water depth). The site is located within the Pine Island cross-shelf trough in the Amundsen Sea Embayment (ASE), West Antarctica (Fig. 1a) and was drilled during RV Polarstern Expedition PS104 in 2017. We further provide the palaeoclimate modeling analytical scripts related to this work.
