Sediments in Van Diemen Gulf Near Melville Island, Australia11.5S 131.1E
Sediments can be observed in Northern Australia in Van Diemen Gulf, between Arnhem Land, of the attached Cobourg Peninsula, and Melville Island. The gulf is connected to the Timor Sea in the west by the Clarence Strait and to the Arafura Sea in the north by Dundas Strait (between Melville Island and Cobourg Peninsula). The sediments are carried into the gulf by rivers including 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. At 5786 km2 it is just outside the 100 largest islands in the world, but is the second biggest island in Australia, after Tasmania (and excluding the continental landmass).
Visible by the bottom edge is the Lakes Argyle and Kununurra Ramsar Site, which comprises an extensive system of artificial freshwater reservoirs, with their associated permanent wetlands, formed by damming the Ord River in the eastern part of the Kimberley Region of northern Western Australia.
