Here we present sedimentological, micro- and macropalaeontological, inorganic and organic geochemical, palaeomagnetic, and geochronological data as well as X-ray computer-tomography (CT) imagery 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 part of RV Polarstern Expedition PS104 in 2017.
