Tibetan Lakes Region North of Himalayas, China

China - November 23rd, 2011

The Tibet Autonomous Region is located on the Tibetan Plateau, the highest region on earth. In northern Tibet elevations reach an average of over 4,572 metres (15,000 ft).

Physically, Tibet may be divided into two parts, the “lakes region” in the west and north-west, and the “river region”, which spreads out on three sides of the former on the east, south, and west. Both regions receive limited amounts of rainfall as they lie in the rain shadow of the Himalayas (visible crossing the lower half of the image), however the region names are useful in contrasting their hydrological structures.

The lake region is an arid and wind-swept desert, dotted over with large and small lakes, generally salt or alkaline, and intersected by streams. The lakes are generally without outlet, or have only a small effluent.

“The Roof of the World”: Tibet, China

China - December 26th, 2010

The Tibetan Plateau dominates this image of the region of Tibet, in China, often referred to as the “Roof of the World”. The geography of Tibet consists of the high mountains, lakes and rivers lying between Central, East and South Asia.

The Tibetan Plateau includes the Himalaya and many of the highest mountain peaks in the world. One important part of Tibet is the “lake region” in the west and north-west. Despite what its name suggests, the lake region is an arid and wind-swept desert. Here, many individual blue and green lakes can be observed, surrounded by the tan desert landscape.

Lakes in Tibet - February 10th, 2009

The Tibetan Lakes Region, in China, is an arid, windy desert with many mountain ranges and lakes, both large and small, salt and alkaline.

The large lake in the lower left corner is Lumajangdong Co, with an area of 250 km².

The mountains in this area are characterized by their tendency to be disconnected and separated by flat, relatively shallow valleys.

The radar (ASAR) images allow the contours of the mountains and the presence of numerous valleys to be observed in detail.

Lakes in Southern Turkey - November 25th, 2008

Lakes in Southern Turkey - November 25th, 2008

Several lakes in the Lakes Region of southwestern Turkey are visible in this image.

The largest lake, on the far right, is Lake Beyşehir. It is a large freshwater lake whose water level often fluctuates. Lake Beyşehir is used for irrigation, although it is also a national park. In the image, we can see that sediments have turned parts of it a greyish tan color, while algae has made other parts green.

To the left of Lake Beyşehir is Lake Eğirdir. With an area of 482 km2 it is the fourth largest (second largest freshwater) lake in Turkey. It has some grey-tan sediments as well, although it seems to contain more blue-green algae.

Southwest of Lake Eğirdir we have Lake Burdur which, unlike the previous two, is a large saline lake. Water level in the lake fluctuates, and it is also an important wetland site for many bird species.

Finally, to the left of Lake Burdur we can see the outline of Lake Acıgöl (literally “the bitter lake” in Turkish). Its surface area varies greatly through the seasons, with 100 km² in spring and 35 km² in late summer, with a maximum depth of 1.63 m. In the image, the surface level appears low around the edges, with a deeper green pool in the center.

Lake Acıgöl, fed primarily by high-sulfate springs issuing from a fault line on its south side, is notable for its sodium sulfate reserves. It is estimated to contain 12.5 million mt of sodium sulfate in the surface and in the subsurface brine. These reserves extensively used in the industry and Turkey’s largest commercial sodium sulfate production operations are based here.
