Glacial dynamics, distribution of cryobethic algae and fish and a 3D model of the grounding zone of a tidewater cliff in front of Coats Land's coast
The grounding zone of the Antarctic ice-shelf – the ice-sheet, bed, and grounding zone – is largely unknown. We used a ROV (remotely operated vehicle) to explore the grounding zone of a tidewater cliff in front of Coats Land's coast during Polarstern expedition PS111 in 2017/2018 to the souther...
