Salt Flats of Lake Eyre, Australia

Australia - April 9th, 2012

During years of especially high rainfall, all the riverbeds in the vast, mostly flat, arid and semi-arid areas of Australia lead inland towards Lake Eyre in central South Australia. Most of the water reaching Lake Eyre comes from the river systems of semi-arid inland Queensland, roughly 1000 kilometres to the north.

Lake Eyre itself lies approximately 16 metres below sea level, and usually contains only salt. In flood years it fills and for a short time undergoes a period of rapid growth and fertility: long-dormant marine creatures multiply and large flocks of waterfowl arrive to feed and raise their young before the waters evaporate once more. Here, the lake appears mostly dry and salty, as evidenced by the white coloring.

Argentina - March 31st, 2012

A plume of smoke can be seen blowing due southward from the northwestern part of Mar Chiquita, in the Argentine province of Córdoba. Sediments and algae can be seen on the lake itself, coloring it dark green. The northern shores are lined by white and grey salt flats.

Lakes Urmia and Sevan, Iran and Armenia – March 10th, 2012

Caspian Sea - March 7th, 2012

The bright green lake in the lower part of this image is Lake Urmia, in Iran. The edges of the lake appear white as they are framed by salt flats. The southern part of the lake is shallower and thus appears lighter in color and shows more salt flats.

In the upper part of the image, on the contrary, is Lake Sevan, the largest lake in Armenia and the Caucasus region. It is one of the largest high-altitude lakes in the world. The lake appears dark blue in color, as it is significantly deeper than its southern neighbor. Lake Sevan is situated in the central part of the Republic of Armenia, inside the Gegharkunik Province, at the altitude of 1,900m above sea level. The total surface area of its basin is about 5,000 km2, the lake itself is 940 km2, and the volume is 34.0 bln cubic meters.

Salt-Ringed Shores of Lake Urmia, Iran

Iran - December 30th, 2011

Lake Urmia is a salt lake in northwestern Iran, near Iran’s border with Turkey. The lake is between the Iranian provinces of East Azerbaijan and West Azerbaijan, west of the southern portion of the similarly shaped Caspian Sea (visible in the full image).Here, Lake Urmia appears green in color, and ringed by white salt flats. A slight haze partially veils the skies over the lake.

Lake Urmia is the largest lake in the Middle East, and the third largest salt water lake on earth, with a surface area of approximately 5,200 km² (2,000 mile²), 140 km (87 mi) length, 55 km (34 mi) width, and 16 m (52 ft) depth. However, the construction of a dam on part of the lake and the recent drought has significantly decreased the annual amount of water it receives. This in turn has increased the salinity of its water, causing the lake to lose its significance as home to thousands of migratory birds including the large flamingo populations.

 

Dust from Salt Flats by Mar Chiquita, Argentina – September 6th, 2011

Argentina - September 4th, 2011

Strong gusts of wind blow dust, or more likely salt and minerals, from the salt flats by Mar Chiquita, an endorheic salt lake located in the northeast of the province of Córdoba, in central Argentina, northwards.

The lake occupies the southern part of a depression that measures about 80 km (north–south) by 45 km (east–west). Its surface area varies considerably, given its shallow depth (about 10 m), and ranges between 2000 and 4500 km² (800 and 1800 mi²).
