Dust Blowing Southward off Salt Flats by Mar Chiquita, Argentina

Argentina – July 7th, 2012

Dust, likely composed of salt and other minerals, blows due southward off the salt flats located near the northern shores of Mar Chiquita, a saline lake in the Argentine province of Córdoba. Visible to the northwest are two other large salt flats: the Salinas Grandes. A plume of smoke from a wildfire near the foothills of the Andes can be observed north of those salt flats, at the top left. The smoke is blowing to the south, similar to the dust.

Spine of the Andes and Salt Flats in Argentina

Argentina - June 5th, 2012

While the spine of the Andes Mountains, running along the Chile-Argentina border, appears bright white due to snowfall, it is not the only bright white feature on the South American landscape nearby: several salt flats are visible to the east, in Argentina. Visible near the foothills of the Andes are the Salinas Grandes, a salt desert in the Córdoba and Santiago del Estero provinces of the Sierras de Córdoba that covers an area of 3,200 mi² (8,290 km²). Further east, salt flats can be seen by the northern shores of the Mar Chiquita, an endorheic salt lake that is the largest of the naturally occurring saline lakes in Argentina. Here, some dust (probably salt and other minerals) can be seen blowing off the Mar Chiquita salt flats and southward over the lake.

Salt Flats in Remains of Aral Sea

Aral Sea - May 19th, 2012

The remains of the Aral Sea, once one of the four largest lakes in the world with an area of 68,000 square kilometres (26,300 sq mi), appear mainly as a large salt pan flanked by small bodies of water in the basins to the west and north. By 2007, the lake had declined to 10% of its original size, splitting into four lakes. By 2009, the southeastern lake had disappeared and the southwestern lake retreated to a thin strip at the extreme west of the former southern sea. The maximum depth of the North Aral Sea is a mere 42 m (138 ft) (as of 2008).

Causeway Separating Lake Urmia into Two Halves, Iran

Iran - June 9th, 2012

The northern half of Lake Urmia, in Iran, appears greenish, while the southern half is rusty red in color. The lake is divided into northern and southern parts separated by a causeway, in which a 1500m gap provides little exchange of water between the two parts. The causeway is visible in this image, near the center of the lake. Due to drought and increased demands for agricultural water in the lake’s basin, the salinity of the lake has risen to more than 300 g/L during recent years, and large areas of the lake bed have been desiccated. These dessicated areas appear as white salt flats.

Effects of Desertification: Dust Storm Over Shrinking Aral Sea – May 22nd, 2012

Aral Sea - May 21st, 2012

Plumes of dust blow westward, off the lakebed of the Aral Sea. The white color of the dust and the region in which the storm is occuring indicate that it has a high salt content. Vast salt plains exposed by the shrinking Aral Sea have been producing more and more dust storms over the years, making regional winters colder and summers hotter. Also, crops in the region are destroyed by salt being deposited onto the land.
