The data presents sedimentological data (relative percentages of silt, clay, together with smectite, illite, kaolinite, and chlorite relative percentages) from gravity core MD03-2611. The sedimentological data was obtained by Dr. Franz Gingele and first published in Gingele et al. (2004) but was not yet freely accessible. The 11.97 m long core MD03-2611 was collected during the AUSCAN cruise in 2003 on-board the research vessel Marion Dufresne II (Hill and De Deckker, 2004; https://doi.org/10.17600/3200090). It was retrieved from a small plateau south of Kangaroo Island at 2420 m depth (36°43.80'S, 136°32.90'E) facing the mouth of the Murray River. The datasets cover the last 94 ka and have been used to understand how deep-sea benthic environments respond to changes occurring within surface waters and on land.
