Wildfire West of Krasnoyarsk Reservoir, Russia

Mongolia and Russia – May 31st, 2012

Many bodies of water can be observed in this image. In the upper part is the Krasnoyarsk Reservoir, created by the dam of the same name on the Yenisey River, in Russia. The Krasnoyarsk dam has greatly affected the local climate. Before the dam was built, the Yenisey in that area was free from ice around 196 days per year. Now it is free from ice the entire year up to 300 to 400 km downstream. The huge amount of water stored in Krasnoyarskoye reservoir makes the local climate more warm and humid.

Also of interest near the reservoir, to its west, is a wildfire (best observed at the top left of the full image). Smoke from the fire is blowing in a straight line towards the southwest.

Visible in the lower half of the image are several lakes in Mongolia: the rounded Lake Uvs Nuur, Lake Khyargas (below the former), Lake Airag (the small green lake just below Lake Khyargas), and, near the bottom edge from right to left, Lakes Khar, Dörgön and Khar-Us.

The Krasnoyarskoye Reservoir, on the Yenisei River in Russia, is one of the largest man-made lakes in Siberia. It is visible here as a thick navy blue line in a curved shape near the center of the image.

Upon opening the full image, many tan and brown fields can be seen by the northern part of the reservoir. The remainder of the surrounding land is mostly forested. The city of Krasnoyarsk is also visible on the banks of the Yenisei past the northern end of the reservoir.

The long, thick, navy blue curved line through the center of this image is the Krasnoyarskoye Reservoir on the Yenisei River, in Russia. The reservoir is one of the largest man-made lakes of river origin in Siberia.

It is situated in Russia’s Krasnoyarsky District. In this image, taken in summer, the Siberian landscape is free of snow and has varying shades of green. The drainage basin of the reservoir covers three natural zones, forest, forest-steppe and steppe, located in the eastern part of the Sayan Altai mountain range. The forest areas are darker green, while the steppes are brownish in color.

Lake Baikal, the mountains near its coasts, nearby rivers and streams, and much of the surrounding Siberian terrain all appear covered in ice or snow in this winter image. Lake Baikal is in a rift valley, created by the Baikal Rift Zone, where the crust of the earth is pulling apart.

At 636 kilometres (395 mi) long and 79 kilometres (49 mi) wide, Lake Baikal has the largest surface area of any freshwater lake in Asia (31,722 km2/12,248 sq mi) and is the deepest lake in the world (1,642 m/5,390 ft). The bottom of the lake is 1,186.5 metres (3,893 ft) below sea level, but below this lies some 7 kilometres (4.3 mi) of sediment, placing the rift floor some 8–11 kilometres (more than 5 miles) below the surface: the deepest continental rift on Earth.

In geological terms, the rift is young and active—it widens about two cm per year. The fault zone is also seismically active; there are hot springs in the area and notable earthquakes every few years. The lake drains into the Angara tributary of the Yenisei.

Sediments in Gulf of Ob and Khalmyer Bay, Russia – August 13th, 2009

The long, narrow Gydan Peninsula in Russian Siberia separates the Gulf of Ob (left) from the Khalmyer Bay (right). Both bodies of water are loaded with sediments, although the former is dark brown in color while the latter appears yellow and green.

The Gulf of Ob is an immense bay of the Arctic Ocean in Northern Russia, at the head of which is the mouth of the Ob River. This Gulf flows into the Kara Sea between the Yamal Peninsula (lower left quadrant) and the Gydan Peninsula.

The Gulf is about 1,000 km (600 mi) long and varies from about 50 km (30 mi) to 80 km (50 mi) in width, running generally north and south. It is relatively shallow, with an average depth from ten to twelve metres which restricts heavy sea transport.

Khalmyer Bay, on the other hand, is roughly 185 km long and 47 km wide at its widest point. This deep bay lies in the Kara Sea between the estuaries of the Ob and the Yenisei River. Khalmyer Bay is surrounded by tundra coast and there are numerous river mouths on its shores.
