Australia - December 30th, 2011

The large, orange-red expanse in the upper left quadrant of this image is the Simpson Desert, a large area of dry, red sandy plain and dunes in Northern Territory, South Australia and Queensland in central Australia. It is the fourth largest Australian desert, with an area of 176,500 km² (68,100 sq mi).

Visible east of the desert is Australia’s Channel Country, a region of outback Australia located mostly in the state of Queensland but also in portions of South Australia, Northern Territory and New South Wales. The Channel Country features an arid landscape with a series of ancient flood plains from rivers which only flow intermittently. The numerous intertwined rivulets that cross the region cover 150,000 km². The principal rivers are Georgina River, Cooper Creek and the Diamantina River.

When there is sufficient rainfall in their catchment area these rivers flow into Lake Eyre, South Australia. Here, the land around the rivulets appears brown, indicating little water flowing through them and causing green vegetation to flourish, and Lake Eyre is mostly white, indicating that water has dried up and left salt flats exposed.

The Simpson Desert (upper left quadrant) is a large area of dry, red sandy plain and dunes in Northern Territory, South Australia and Queensland in central Australia. It is the fourth largest Australian desert, with an area of 176,500 km² (68,100 sq mi).

Visible to the east of the desert is Australia’s Channel Country, a region of outback Australia located mostly in the state of Queensland but also in portions of South Australia, Northern Territory and New South Wales. The name comes from the numerous intertwined rivulets that cross the region. The principal rivers are Georgina River, Cooper Creek and the Diamantina River.

When there is sufficient rainfall in their catchment area these rivers flow into Lake Eyre, South Australia. Lake Eyre is visible at the bottom edge, its southwestern basin appearing green in color and its southeastern basin appearing pinkish, framed by white salt flats.

Australia - July 6th, 2011

This FAPAR image shows the vegetation index of part of Australia’s Channel Country. The land on the floodplain of the multi-channelled Cooper Creek, formed by the joining of the Thomson and Barcoo Rivers, shows a good index (green).

The rest of the surrounding landscape shows low levels of photosynthetic activity (light yellow). The large grey area west of the river, where no vegetation index data is available, is Lake Yamma Yamma (also know as Lake Mackillop).

Australia - April 16th, 2011

Cooper Creek is an intermittent river in east central Australia’s Channel Country, an area of wide floodplains, grooved by rivers. Here, the river appears green and tan from sediments, and the land of the floodplain surrounding it is mostly green in color.

Rising as the Barcoo on the northern slopes of the Warrego Range, Queensland, the river flows northwest to Blackall. Joined by the Alice River, it continues southwest past Isisford and receives its principal tributary, the Thomson, from which point it is known as Cooper Creek.

It crosses the South Australian border, and carries water to Lake Eyre only during wet-year floods. Average annual discharge at Currareva is 2,900 cu ft (82 cu m) per second.
