Isis remotely-operated vehicle (ROV) bathymetry data in Marguerite Trough, Antarctica, from James Clark Ross cruise JR157, 2007
On cruise JR157 the Isis ROV was deployed on 15 dives in the Marguerite Trough area in January and February 2007. Dives 10 and 11 targeted a bedrock channel system on the inner continental shelf to investigate channel incision processes and the history of glaciation in the area. The plan was to map...
