Sediments in Van Diemen Gulf Near Melville Island, Australia

Australia - January 12th, 2012

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.

Australia and New Guinea - August 2nd, 2011

Sediments and possibly phytoplankton growth color the Arafura Sea (above) and the Gulf of Carpentaria (below). The sediments are particularly concentrated along the coasts of the Gulf and of New Guinea (top).

The Arafura Sea lies west of the Pacific Ocean, overlying the continental shelf between Australia and New Guinea. It is bordered by the Torres Strait and through that the Coral Sea to the east, the Gulf of Carpentaria to the south, the Timor Sea to the west and the Banda and Ceram seas to the northwest.

It is 1,290 kilometres (800 miles) long and 560 kilometres (350 miles) wide. The depth of the sea is primarily 50-80 metres (165-265 feet) with the depth increasing to the west. As a shallow tropical sea, its waters are a breeding ground for tropical cyclones.

Sediments create a wide tan frame along the southern coast of Papua province, Indonesia, on the island of New Guinea.

These sediments surround the islands of Yos Sudarso and Komoran. The former, also known as Pulau Dolak, is leaf shaped and about 165 km long with an area of 11,600 km².

Komoran is an island just south of the much larger Yos Sudarso near the south coast of New Guinea in Papua province, Indonesia. Its area is 695 km².

Meanwhile, on the western coast, the Digul River spills golden brown sediments into the Arafura Sea. The 525 kilometer- (326 mi-) long river travels across a low region of extensive swamps for much of its length and creates a delta near Yos Sudarso Island.
