Mongolia - May 6th, 2012

As its name would suggest, Mongolia’s Great Lakes Depression contains several large bodies of water. Visible near the top edge is Lake Uvs Nuur, which appears bright white here as its surface is frozen.

In the center of the image, south of Lake Uvs, are Lake Khyargas (above) and Lake Airag (below). The former is significantly larger than the latter. It is dark blue in color, although the eastern half is slightly greener. The smaller Lake Airag is bright green.

Continuing south, several other lakes can be observed near the bottom of the image: Lake Khar, Lake Dörgön and Lake Khar-Us (right to left). These lakes show varying shades of blue, green and brown.

Several lakes can be observed in Mongolia’s Uvs province, located in the west of the country. The province has both mountainous and Gobi semi-desert climatic zones, although this image focuses on the latter.

The five lakes visible here belong to the country’s Great Lakes Depression. The northernmost is Lake Khyargas, dark greenish blue with an elongated shape and irregular edges. Smaller, greener in color and just to its south is Lake Airag. Due south of those two are Lake Khar (green) and Lake Dörgön (further south, dark blue). Finally, the irregularly shaped Lake Khar-Us, showing various shades of green, is located west of the aforementioned pair.

The lakes visible here in the Khyargas District of Mongolia’s Uvs Province are part of the same system interconnected lakes in the Great Lakes Depression.

The large, dark greenish blue lake at the top is Lake Khyargas, upon which the Khyargas Nuur National Park is based.  This protected area was established in 2000 and covers about 3,328 km². It also includes the smaller, lighter green, freshwater Lake Airag, just south of Lake Khyargas.

In the lower left quadrant is Lake Khar-Us. Its area value of 1,852 km² includes the island Agbash (or Ak-Bashi, White Head) with an area of 274 km², so the water surface area is 1,578 km² only. Here, the island appears to almost separate the bright green western side of the lake from the brown right side. Primary inflow is the Khovd Gol river, which creates a large fan-shaped river delta on the western shores.

Finally, in the lower right quadrant are Lakes Khar and Dörgön. The waters of Lake Khar, above, appear green, while those of Lake Dörgön, below, appear dark blue.

Great Lakes Depression, Mongolia - June 8th, 2009

The greenish waters of several lakes in Mongolia’s Great Lakes Depression stand out against the surrounding dry, tan landscape.

The lake on the bottom left is Khar-Us Nuur, or “Black Water Lake” despite its green appearance here. Its area value  of 1,852 km² includes the island Agbash (or Ak-Bashi, White Head), with an area of 274 km², meaning the lake’s actual water surface area is only 1,578 km².

The lake’s primary inflow is from the Khovd Gol river, which creates a large river delta whose fanned shape is visible on the western shore.

It is the upper one in a system of the interconnected lakes: Khar-Us Nuur, Khar Nuur, Dörgön Nuur, Airag Nuur and Khyargas Nuur. Khar Nuur (above) and Dörgön Nuur (below) are located to the east of Khar-Us Nuur, while Khyargas Nuur (above) and Airag Nuur (below) are situated to the north.

Russia – June 28th, 2012

Hundreds of wildfires continue to burn across Russia, and more than 14 new fires have broken out over the past 24 hours (click here for previous images). While eleven of them have been put out, firefighters are still struggling to extinguish another 32 blazes. Authorities say the fires do not pose a threat to residential areas.

Here, smoke from fires north of the border area between Russia (above) and Mongolia (lower right) and Kazakhstan (lower left) can be observed blowing towards the south. Visible in the lower right quadrant is Mongolia’s Great Lakes Depression, including the large, rounded Lake Uvs Nuur.
