Prydz Bay
Seaward of the Amery Ice Shelf, Prydz Bay shows bathymetry typical of glaciated margins with deeper water near the coast with a broad topographic basin, the Amery Depression that is around -700 m MSL along the front of the Amery Ice Shelf. The Amery Depression shoals gently to outer shelf banks around 100–200 m deep. The shelf break is at around 400–500 m. The western side of Prydz Bay features a broad trough crossing from the inner shelf to the shelf edge, Prydz Channel. It is around 100 km wide and is 500 m deep at the shelf break. It is a typical example of a cross-shelf glacial trough that occupy 40.2% of the area of the Antarctic continental shelf and that are formed by fast-flowing ice streams.
