Salty Surfaces of Lakes Gairdner and Torrens, Australia

Australia – January 26th, 2013

Several salt lakes that usually remain dry can be observed in this image of South Australia. By the top center is Lake Torrens.  Usually a dry salt flat, it has only been filled with water once in the past 150 years. Thunderstorms occasionally provide a small amount of water in the lake, when this occurs the area attracts a variety of birdlife.

Visible to its west is Lake Gairdner, a large endorheic lake in central South Australia, in the Gawler Ranges. When it is flooded, it is considered the fourth largest salt lake in Australia. The lake is over 160 km (99 mi) long and 48 km (30 mi) across with salt over 1.2 metres (4 ft) thick in some places.

Australia - April 14th, 2012

The large white areas in the upper left quadrant of this image of Southern Australia are Lake Torrens and Lake Gairdner, two large salt lakes. The former lies between the Arcoona Plateau to the west and the Flinders Ranges to the east. It stretches approximately 200km in length and 30km in average width. It has a thin salt crust with red-brown clays beneath which are soft and boggy. Lake Gairdner is a large endorheic lake,  over 160 km long and 48 km across with salt over 1.2 metres (4 ft) thick in some places.

Australia - March 31st, 2011

Several salt lakes appear as white salt flats in this image of South Australia, the largest of which are Lake Gardner (left) and Lake Torrens (right). Also visible in the full image is Lake Frome, further east.

Running between Lakes Torrens and Frome are the Flinders Ranges, the largest mountain range in South Australia. The ranges appear here as a dark brown area.

South of the ranges and Lake Torrens is the Spencer Gulf, appearing green from sediments and algal growth. To the southeast of Spencer Gulf, in the full image, is Gulf St. Vincent.

Area of Convection Over South Australia

Australia - January 31st, 2011

An interesting, ball-shaped area of convection can be observed in South Australia, north of the Spencer Gulf. This area of convection was present at the same time Tropical Cyclone Yasi (11P) was affecting Queensland, Australia, to the north.

Several of the rivers in Australia’s Channel Country can be observed as brown lines just northwest of the convective area. To the southwest, Lake Torrens and Lake Gardner appear as large white salt flats.

Australia - November 9th, 2010

Sediments are present into the Spencer Gulf (west) and Gulf St. Vincent (east), the two of which are separated by the Yorke Peninsula. The city of Adelaide is located by the shores of Gulf St. Vincent.

Moving inland from the apex of Spencer Gulf, the Flinders Ranges appear as a dark brown area. In the full image, the almost swirled shape of the individual ridges can be observed. The ranges lie between Lake Torrens (west) and Lake Frome (east). Both are usually dry salt flats, hence the whitish grey color.
