This record describes the deep-sea sediment core products produced by Holder et al. (2020) from two sites in the Sabrina Coast continental slope and rise, the first sedimentary sequences investigated in this region of the East Antarctic. The cores were used to study changes in the oceanic and depositional environment and their interaction with the nearby Totten Glacier. The two archives show clear variations between glacial and interglacial phases over the last 350 Kyrs, driven by the movement of the ice sheet advancing and retreating over the continental shelf and ocean circulation patterns that deliver heat either close to the Antarctic coastline or further away from the continental slope. This research provided a foundation for future palaeoceanographic work in the region and suggested that warm oceanic conditions, similar to today, have influenced the Sabrina Coast during past warm interglacials over the last 350 Kyrs.
