North Australian Basin

The North Australian Basin (NAB; formerly Argo Abyssal Plain, or Argo Plain) is an oceanic basin in the easternmost corner of the Indian Ocean between northwest Australia and Indonesia.

It was discovered by the U.S. research vessel "Argo" of the Scripps Institution of Oceanography in 1960.

From the north, east, south and southwest it is respectively bounded by the Java Trench, the submerged continental crust of the Scott Plateau, Rowley Terrace, and the Exmouth Planeau with the Wombat Plateau.

[citation needed] To the west it is separated from the Gascoyne Abyssal Plain by the Joey and Roo Rises[a] north of the Platypus Spur.

[5] It has been suggested that the opening of the Argo Abyssal Plain was due to the rifting of a continental sliver off the passive margin of northeastern Gondwana in the Late Jurassic.
