Geography of Sakhalin (Russia)

The only part of Russia that is fully made up of islands is the Sakhalin Oblast. It is made up of Sakhalin Island, the Kuril Islands, and the tiny neighbouring islands of Moneron and Tyuleny. The largest island, Sakhalin, is made up of many lakes and rivers that form the "scales" of a fish-like shape. Orography and geological structure of the island are not fully understood. Yuzhno Sakhalinsk serves as Sakhalin's capital.

Physical Features

The Soya Strait or La Pérouse Strait separates Hokkaido, Japan, from Sakhalin, which is separated from the mainland by the shallow, narrow Strait of Tartary, which frequently freezes in the winter in its narrowest half. Sakhalin, which measures 948 kilometers (589 mi) in length, 25 to 170 km (16 to 106 mi) in width, and covers an area of 72,492 km2 (27,989 sq mi), is the largest island in Russia. It shares latitudes with Ireland, Wales, and England. Crystalline rocks appear at a number of capes, while Cretaceous limestones from Dui on the west coast have an extensive and unique fauna of enormous ammonites.

Tertiary conglomerates, sandstones, marls, and clays, folded by later upheavals, are also widespread throughout the island. The clays, which have layers of high-quality coal and an abundance of preserved plant, demonstrate that Sakhalin was once part of a continent that included north Asia, Alaska, and Japan and that it had a relatively mild climate during the Miocene epoch. The mollusk fauna found in the Pliocene sediments is more Arctic than the one seen now, suggesting that the connection between the Pacific and Arctic Oceans was likely wider than it is now.

Cape of Elisabeth on the Schmidt Peninsula is Sakhalin's most northern point, and Cape Crillon is its most southern. Moneron Island and Ush Island are two of the smaller islands that are connected to Sakhalin. Moneron, the lone land mass in the Tatar Strait, is 7.2 nautical miles (44 km) long and 5.6 nautical miles (3.5 mi) wide. It is located 41 nautical miles (76 km) from the port city of Nevelsk and 24 nautical miles (44 km) west of the nearest Sakhalin coast. Off Sakhalin's northern coast is the island of Ush.

Climate

Sakhalin has a chilly, humid climate that ranges from humid continental in the south to subarctic in the center and north thanks to the Sea of Okhotsk. Although the winters are much colder and a few degrees warmer than in interior East Asian towns at the same latitude, the summers are significantly cooler than in similar-latitude inland cities like Harbin or Irkutsk. Summers are cloudy and don't get much sun.

Due to the strong onshore winds in the summer and the frequent North Pacific storms that impact the island in the fall, precipitation is significant. On the northwest coast, it is roughly 500 millimeters (20 in) while in the southern mountainous areas, it is over 1,200 millimeters. Onshore breezes guarantee Sakhalin enjoys year-round precipitation with an October peak, unlike interior east Asia with its marked summer maxima.

Flora and Fauna

The entire island is covered in thick forests, primarily conifers. There are lots of bears, foxes, otters, sables, reindeer in the north, musk deer, hares, squirrels, rats, and mice. The majority of the bird population is made up of common east Siberian species, although there are a few endemic or nearly endemic species that breed there, including the critically endangered Sakhalin leaf warbler (Phylloscopus borealoides) and Nordmann's greenshank (Tringa guttifer).

Fish of all kinds, notably salmon species (Oncorhynchus), are abundant in the rivers. The severely endangered Western Pacific grey whale, whose sole known feeding place is the Sakhalin shore, is one of many whales that frequent the sea coast. The North Pacific right whale, the bowhead whale, and the beluga whale are other endangered whale species that are known to inhabit this region.

Rivers

The Tym, one of the main rivers on the island, is 250 miles (400 km) long, can be navigated by rafts and small boats for 50 miles (80 km), and travels north and northeast before it empties into the Sea of Okhotsk. The Poronai River flows from the southeast coast to the Gulf of Patience, also known as Shichiro Bay. At the southernmost point of the island, three other tiny streams enter the broad semicircular Gulf of Aniva or Higashifushimi Bay.

Mountains

Sakhalin is made up of nearly two-thirds mountains. It is divided between two parallel mountain ranges that are 600-1,500 m (2,000-4,900 ft) high. The highest peak in the Western Sakhalin Mountains is Mount Ichara (1,481 m/4,859 ft), whereas Mount Lopatin (1,609 m/5,279 ft) is the highest peak in the Eastern Sakhalin Mountains and the highest mountain on the island. The two ranges are divided by the Tym-Poronaiskaya Valley. The island is traversed by the Susuanaisky and Tonino-Anivsky ranges in the south, with the Northern-Sakhalin plain taking up the majority of the island's northern territory.

Vegetation

The vegetation varies from tundra to willow and birch forests that are stunted in the north to thick deciduous forests in the south. Around the coast, the main economic activity is fishing, mostly for crab, herring, cod, and salmon. Coal mining, logging, including paper manufacture, and oil and gas extraction in the north form the foundation of the rest of the economy. Raising animals is the primary agricultural activity.

Conclusion

The largest island in Russia and a part of Sakhalin Oblast, Sakhalin Island is renowned for its variety of geographical features. Its design is similar to a fish, and it is covered in lakes and rivers. The island has a cold, humid temperature, and it is completely covered in dense forests. Bears, foxes, otters, and many bird species, some of which are endemic, can all be found on Sakhalin.

Fishing, coal mining, logging, and oil and gas extraction are all important to the economy. Sakhalin is a fascinating and significant location in Russia's far east due to its distinctive geography and natural riches.
