It is centered at 10° N, 65° E.[1] The basin depth ranges from 3,400 m in the north to 4,400 m in the south, with a maximum depth of 4,652 m.[1] The floor is covered by sediments from the Indus submarine fan and is relatively smooth.
Bottom water enters the basin through the Owen fracture zone to the west.
