Australia – June 1st, 2013

Sediments cause the coastline of Australia’s Northern Territory to appear bright shades of gold and green, particularly in the Joseph Bonaparte Gulf (lower left quadrant) and the Van Diemen Gulf (upper right quadrant) between the mainland and Melville Island. A darker green and blue expanse of water west of the island may be colored as such due to phytoplankton rather than sediments. On the mainland, several plumes of smoke from fires can be seen blowing towards the west-northwest.

Thick Plumes of Smoke at Start of Northern Australia Bushfire Season – June 28th, 2012

Australia – June 26th, 2012

The 2012 northern Australia bushfire season has gotten off to an intense start, as can be observed from the many thick plumes of smoke visible here, in the country’s Northern Territory. Most of the plumes are blowing towards the northwest, although shifting winds are carrying a few towards the west-southwest.

Winter is northern Australia’s fire season due to the drying out of summer grasses and lack of rainfall. This, combined with warm temperatures, dry winds and low humidity makes conditions ripe for the start and spread of fires. Also of note in this image are sediments along the coastline, particularly in the Van Diemen Gulf, between the mainland and the large Melville Island.

Fires in Northern Territory and Sediments Around Melville Island, Australia – March 13th, 2012

Australia - May 12th, 2012

Sediments surround Melville Island and fill the Van Diemen Gulf, off the coast of the Northern Territory of Australia. Melville Island is located in the Timor Sea, west of the Cobourg Peninsula in Arnhem Land and north of Darwin. Visible on the Australian mainland, in the lower right quadrant, are plumes of smoke from two wildfires, blowing towards the west-northwest.

Australia - January 12th, 2012

This FAPAR image shows the vegetation index of part of Australia’s Northern Territory, near the border with Western Australia. The index is good (green) near the coast, particularly between Van Diemen Gulf (top center) and Joseph Bonaparte Gulf (left center).

The index is also good on Melville Island, by Van Diemen Gulf, and on the Cobourg Peninsula, east of the island, Arnhem Land, as well as around Lake Argyle (south of Joseph Bonaparte Gulf). As one moves further inland and away from these bodies of water, the index of photosynthetic activity becomes progressively lower (yellow).

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.
