Sediments in Van Diemen Gulf Near Melville Island, Australia11.5S 131.1E
Sediments create tan and green streaks in the Van Diemen Gulf, a gulf between Arnhem Land, of the attached Cobourg Peninsula, and Melville Island in northern Australia. The sediments are being released into the gulf from the South Alligator River, the East Alligator River and the Adelaide River.
The gulf 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.
