The Amur and Poronai Rivers in the Russian Far East

Russia and Japan - September 9th, 2010

The main body of land on the left belongs to Russia, as does the section of Sakhalin Island extending downward from the top center. The island below is Hokkaido, belong to Japan. A small portion of Japan’s main island, Honshu, is visible just below Honshu, at the very bottom.

The wide river carrying dark brown sediments on the Russian mainland is the Amur. The main rivers on Sakhalin island are the Tym and the Poronai. The latter flows south-south-east to the Gulf of Patience or Shichiro Bay, on the south-east coast.

In the full image, a reddish brown lake can be seen near the mouth of the Poronai and the shores of the gulf. Further down, three other small streams enter the wide semicircular Gulf of Aniva or Higashifushimi Bay at the southern extremity of the island.

Confluence of the Ussuri and Amur Rivers, Russia and China – May 31st, 2010

The Ussuri River, visible by the right edge of this orthorectified image, forms for a considerable distance the boundary between China (Heilongjiang Province, visible here to the left) and Russia (Siberia, visible here to the right).

It is a northward-flowing tributary of the Amur River; the two rivers’ confluence is visible beyond the hills in the upper right corner. The Ussuri’s length from the source of the Ulakhe is 565 miles (909 km), and its basin is 72,200 square miles (187,000 square km) in area.

The Ussuri is formed by the confluence of the Sungacha (Song’acha) River, the outlet of Lake Khanka (Xingkai); and the Ulakhe and Arsenyevka rivers, both of which rise on the southwestern slopes of the Sikhote-Alin mountain complex.

Ice Floes Off the Coast of Russia in the Sea of Okhotsk

Russia - February 24th, 2010

The terrain of Russian Siberia near the city of Okhotsk (shoreline, left, near the mouth of the Okhota River) appears white due to snow cover, as does much of the Sea of Okhotsk below, due to ice. Many large ice floes are visible off the coast.

The Sea of Okhotsk is a part of the western Pacific Ocean, lying between the Kamchatka Peninsula on the east, the Kuril Islands on the southeast, the island of Hokkaidō to the far south, the island of Sakhalin along the west, and a long stretch of eastern Siberian coast (including the Shantar Islands) along the west and north.

The Sea covers 611,000 sq.mi. (1,583,000 km2.), with a mean depth of 2,818 feet (859 metres). Its maximum depth is 11,063 feet (3,372 metres).

In winter, navigation on the Sea of Okhotsk becomes difficult, or even impossible, due to the formation of large ice floes, because the large amount of freshwater from the Amur River lowers the salinity and raises the freezing point of the sea. The distribution and thickness of ice floes depends on many factors: the location, the time of year, water currents, and the sea temperatures.

Mouth of the Amur River, Russia

Russia - August 7th, 2009

The Amur River carries brown sediments across northeastern Russia into in the Strait of Tartary, between the Russian mainland and Sakhalin Island.

The Amur is the world’s ninth longest river, forming the border between the Russian Far East and Northeastern China, where it is known as the Heilong Jiang.

Flowing across northeast Asia for over 4,444 km (2,761 mi), from the mountains of northeastern China to the Sea of Okhotsk (near Nikolayevsk-na-Amure), it drains a remarkable watershed that includes diverse landscapes of desert, steppe, tundra, and taiga, eventually emptying into the sea through the Strait of Tartary, where the mouth of the river faces the northern end of the island of Sakhalin.

The average annual discharge varies from 6000 m³/s (1980) – 12000 m³/s (1957), leading to an average 9819 m³/s or 310 km³ per year.

Lake Khanka on Russian-Chinese Border Still Ice-Covered

Khanka Lake, Russia and China - April 14th, 2009

Khanka Lake, Russia and China - April 14th, 2009

Khanka Lake is a transboundary freshwater body located on the border between Heilongjiang Province in northeast China and Primorsky Krai in Russia.

Khanka Lake is actually two lakes separated by a 10 m sandy hill. The shores of the lake are swampy, except in the north-west.

The lake’s drainage basin is an alluvial plain of around 16,890 km², of which 97% is on Russian territory. With 4,000 to 4,400 km² of water plane area, it is the largest body of water in northeast China.

It is fed by 23 rivers (8 in China and 15 in Russia), but the only outflow of the lake is the Songacha River. The lake belongs to the Ussuri River System, which is part of Amur River System.

The lake’s average depth is 4.5 m, maximum depth—10.6 m. Its average volume is 18.3 km³, maximum—22.6 km³.

Rainfall mainly occurs in summer, reaching 750 mm annually. Maximum annual temperature is 21.2°C, minimum is −19.2°C. Here, the lake is still covered in ice, although it is gradually cracking. The land around the lake appears mostly thawed, though some snow is visible on the ground to the northwest.
