Bright White Hypersaline Lake Tuz, Turkey

38.7N 33.3E

December 7th, 2011 Category: Lakes, Salt Flats

Turkey - November 25th, 2011

The saline Lake Tuz appears bright white in this image of central Anatolia, Turkey. To the north is the reservoir created by the Hirfanlı Dam, appearing dark blue in color.

Lake Tuz is the second largest lake in Turkey, with a surface area of 1,665 km2 (643 sq mi), and one of the largest hypersaline lakes in the world. The lake, occupying a tectonic depression in the central plateau of Turkey, is fed by two major streams, groundwater, and surface water, but has no outlet. Brackish marshes have formed where channels and streams enter the lake. Arable fields surround the lake, except in the south and southwest where extensive seasonally flooded salt-steppe occurs.

For most of the year, it is very shallow (approx.0.4 m (1 ft)). During winter part of the salt is dissolved in the fresh water that is introduced to the lake by precipitation and surface runoff (to 32.9% salinity). During the summer the lake dries up exposing an average of 30 cm thick salt layer in August. This mechanism is used as a basis for the process of the salt mines in the lake.

Saline Lake Tuz and Freshwater Lake Beyşehir, Turkey

38.7N 33.3E

October 6th, 2011 Category: Lakes

Turkey - October 2nd, 2011

The large, rounded white area near the top edge of this image is Lake Tuz, the third largest lake in Turkey. The white color is due to its shallow waters and high salt content – it is one of the largest hypersaline lakes in the world. The lake is located in the Central Anatolia Region, occupying a tectonic depression in the central plateau of Turkey.

The blue-green lake to the southwest is Lake Beyşehir, a large freshwater lake in Isparta and Konya provinces. It has an area of 650.00 km² and is 45 km long and 20 km wide. Water level in the lake often fluctuates by year and by season, and it is used for irrigation.

Visible to the east of the lakes is the Gulf of Iskenderun, a large bay in the Mediterranean Sea. South of the lakes, in the Mediterranean, lies the island-nation of Cyprus.

White Coloring of Salty Lake Tuz in Turkey

July 13th, 2011 Category: Lakes, Salt Flats

Turkey - July 12th, 2011

Several lakes can be observed in Turkey in this image of the northeastern Mediterranean, including the island-nation of Cyprus (lower right quadrant).

The large, white body of water is the salty Lake Tuz, the third largest lake in Turkey. It occupies a tectonic depression in the central plateau of the country. During the summer the lake dries up exposing an average of 30 cm thick salt layer in August, hence the bright white color visible in this image acquired in late July.

Southwest of Lake Tuz are two bright turquoise bodies of water: Lake Eğirdir (left) and Lake Beyşehir (right). Both lie in the Turkish Lakes Region. The former has an area of 482 km², and the latter an area of 650 km².

Lake Tuz in Turkey and Lake Assad in Syria

July 6th, 2011 Category: Lakes

Turkey, Cyprus, Syria - June 21st, 2011

This image of the eastern Mediterranean Sea includes parts of Turkey (above) and Syria (right), with the island nation of Cyprus visible near the left edge.

Several lakes can be observed, including the pinkish Lake Tuz (in Turkey, due north of Cyprus) and the blue Lake Assad (in Syria, northeast of Cyprus). The whitish-pink color of Lake Tuz is partially due to its hypersalinity, while the silvery glow on parts of Lake Assad’s surface is due to sun glint.

Aydar Lake and Kyzyl-Kum Desert, Uzbekistan and Kazakhstan – May 16th, 2011

May 16th, 2011 Category: Deserts, Image of the day, Lakes

Kazakhstan and Uzbekistan - May 2nd, 2011

The elongated lake in the lower half of this image of Uzbekistan and Kazakhstan is Aydar Lake. It is part of a man-made system of lakes, which covers an area of 4,000 square kilometres (1,500 mi²) and includes 3 brackish water lakes: Lakes Aydar, Arnasay and Tuzkan.

Northwest of the lake is the Kyzyl-Kum Desert, whose territory consists mainly of an extensive plain at an altitude up to 300 m (about 1000 feet) above sea level, with a number of the depressions and highlands. Most of the area is covered with sand-dunes, which are best observed in the full image.
