Sediments in Joseph Bonaparte and Van Diemen Gulfs, Australia13.2S 130.0E
Sediments line the coast of Australia’s Northern Territory, giving the waters near the shoreline a tinge that varies from golden brown to green as they disperse. They are particularly dense in the Joseph Bonaparte Gulf (below) and the Van Diemen Gulf (above), between the mainland and Melville Island.
Van Diemen Gulf is a gulf between Arnhem Land, of the attached Cobourg Peninsula and Melville Island in northern Australia. It is connected to the Timor Sea in the west by the Clarence Strait (near the city of Darwin), and to the Arafura Sea in the north by Dundas Strait (between Melville Island and Cobourg Peninsula). It stretches over an area of about 14,000 km². Rivers draining into the Gulf include the South Alligator River, the East Alligator River and the Adelaide River.
Melville Island or Yermalner Island lies in the eastern Timor Sea, off the coast of the Northern Territory of Australia. It is west of the Cobourg Peninsula in Arnhem Land and north of Darwin.
The sediments are much denser and browner in color in the Joseph Bonaparte Gulf, a large body of water off the coast of the Northern Territory, Australia and Western Australia. The Ord River and Victoria River drain into the gulf.
