Turkey - May 13th, 2009

Lake Tuz, located in central Anatolia and known as the second-largest lake of Turkey, may no longer deserve that title as it has shrunk by 85 percent over the last 90 years due to global warming, drought and the over usage of its water for irrigation purposes.

Studies of satellite images by Aksaray University’s Department of Engineering, Geodesy and Photogrammetry Engineering have shown that Lake Tuz covered 216,400 hectares in 1915. Since then, it has shrunk at an alarming rate, decreasing to 92,600 hectares in 1987, and to 32,600 hectares in 2005.

Scientists say that drought, the over usage of water in the lake basin for irrigation and global warming have led to the loss of water in the lake. They are calling for urgent and radical measures to protect Lake Tuz, predicting that if the necessary measures are not taken, the lake will no longer exist by 2015.

Lake Tuz, Turkey - January 12th, 2009

Lake Tuz (Turkish: Tuz Gölü meaning Salt Lake) is the second biggest lake in Turkey, located in the Central Anatolia region.

As its primarily light tan color indicates, for most of the year the lake is very shallow (1-2 m).

It is normally 80 km long and 50 km wide, with an area of 1,600 km², at an elevation of 905 m above sea level.

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.

It is extremely saline and during the summer, when most of the water in the lake dries up and exposes an average of 30 cm thick salt layer.

During winter part of the salt is re-dissolved in the fresh water that is introduced to the lake by precipitation and surface runoff.

The dark blue, non saline lake just north of Lake Tuz is Lake Hirfanli, created by the Hirfanli Dam.

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.

The Kerch Strait connects the Black Sea and the Sea of Azov, separating the Kerch Peninsula in the west from the Taman Peninsula in the east. The strait is 4.5 kilometres (2.8 mi) to 15 kilometres (9.3 mi) wide and up to 18 metres (59 ft) deep.

The most important harbor is the Crimean city of Kerch (Ukraine) which gives its name to the strait, formerly known as the Cimmerian Bosporus.

The Russian side of the strait contains the Taman Bay encircled by the Tuzla Spit to the south and Chushka Spit to the north. The most important settlement on the Russian side is Taman where an important cargo port is under construction.

Eastern Mediterranean - September 24th, 2009

This view of the eastern part of the Mediterranean Sea includes the island nation of Cyprus, as well as (counterclockwise along the shoreline from bottom left) Egypt and the Sinai Peninsula, Israel-Palestine, Lebanon, Syria and Turkey. Inland, Jordan and parts of Saudi Arabia and Iraq are also visible.

The dry, arid landscape occupying most of the image is interrputed by several lakes and rivers. Below, in Egypt, the Nile River Delta creates a wide, fan-shaped green area along the Mediterranean coast.

To the northeast, the Dead Sea can be seen in the Jordan Rift Valley, between Israel-Palestine and the West Bank (left) and Jordan (right). The lower part of this inland sea appears  greenish due to an extensive network of salt evaporation pans called the Dead Sea Dikes.

Continuing to the north, Lake Assad is visible in Syria, connected to the Euphrates River. North of Lake Assad is Lake Atatürk Dam, in Turkey.

Finally, also located in Turkey, at the top left, is Lake Tuz. In contrast with the other lakes seen in this image, Lake Tuz appears bright white. It is a salt lake, and the second largest lake in Turkey.
