Laptev Sea (Arctic Ocean)

Today we are going to talk about Laptev Sea. The Laptev Sea is known as a marginal sea of ​​the Arctic Ocean. The Laptev Sea is located on the northern coast of Siberia, between the Severnaya Zemlya, the Taimyr Peninsula and the New Siberian Islands. The northern boundary of the Laptev Sea extends from the Arctic Cape to a point with coordinates of 79 ° N and 139 ° E and ends at Anisiy Cape. So let's gather some more information about Laptev Sea.

Laptev Sea is named after Russian researchers Dmitry Laptev and Khariton Laptev. This type of sea is mostly stagnant. The coasts have been inhabited for thousands of years by the indigenous tribes of events and events after the Eucalyptus and Laptev Sea and who were engaged in fishing, hunting and reindeer herding.

History

The people of northern Siberia, such as the Chuvans and the Yukaghirs, have lived for centuries on the shores of this sea. All of these people were engaged in fishing, hunting, and the fall of the Cold Territory on the Laptev Sea because they required reindeer sledges for transportation and hunting. The Russians began exploring the shores of the sea and nearby islands in the 17th century. Tiksi is the main port on the Laptev Sea. Various important materials such as wood, fur and other building materials are currently exported worldwide by the Laptev Sea.

Climate

This type of ocean is the Arctic continent. And because of its remoteness from both the Atlantic and Pacific Oceans, Laptev is one of the most intense in the Sea. The air temperature on the Laptev Sea stays below 0 ° С and 9 months in the south. The average sea temperature in January varies between −31 ° C and −34 C and the minimum is −50 ° C.

Snowfall, strong winds and blizzards on the Laptev Sea are common in winter. Snow falls on the Laptev Sea even in summer and alternates with fog. Winds blow from the south and south-west in winter on the Laptev Sea and the average speed of the Laptev Sea is 8 m / s and it flows towards spring.

Marine Life

Due to the extremely harsh climatic conditions, this type of sea lacks flora and fauna. The seaweed is mainly represented by diatoms. Fauna is also rarely found on the Laptev Sea. There are more than 100 species in the Laptev Sea. There are about 10 species of blue-green algae, green algae and flagellate species on the Laptev Sea. This type of ocean is characterized by phytoplankton debris water and also has a concentration of about 0.2 mg / L.

Fish, numerous plants, birds and mammals are kept in the reserves of this type of sea.

About 30 species of zooplankton are also found in the Laptev Sea. More than 39 species of fish are found on the Laptev Sea, including nelma, saffron cod, muksun, Coregonus, omul, sardine, flounder, and sturgeon. Numerous settlements are found along the coast on the straight strip of this type of sea. Some notable birds in this type of sea include Brent goose, snow owl, snow bunting, purple sandpiper, black guillemot, little auk, sterna, Ross’s gull, northern fuller, etc. The Laptev Sea includes a variety of seals.

Geography

The Lena River is known as the largest river flowing in the ocean of this type with its large delta. Other important rivers on the Laptev Sea include the Anabar, Khatanga, Olenyok and Yana. The wind blows along the shores of the Laptev Sea and forms gulfs and bays of various sizes. Coastal landscapes with small mountains are also found in a variety of places along the coast of the Laptev Sea. The main bays of this type of sea are Buor-Khaya Gulf, Khatanga Gulf, Olenyok Gulf, Bur-Khaya Gulf and Yana.

There are several dozen islands on the Laptev Sea and the total area of ​​this island is 78,784 km and it is mostly in the western part of the sea and in the river delta. The melting of ice on this type of sea causes significant storms and currents in the islands. More than half of the Laptev Sea lives on continental shelves with an average depth of less than 50 meters.

In the northern part, the sea floor moves rapidly to the bottom of the Laptev Sea with a depth of 1 km and this type of area is found covered with silt and which merges with the ice in the shallow areas. This type of sea is bounded on the south by the East Siberian Lowland and is an alluvial plain composed mainly of silt of marine origin.

Human Activities

The coast of the Laptev Sea is bordered by the Sakha Republic to the east and the Krasnoyarsk Krai of Russia to the west. The coastal settlements of the Laptev Sea are few and far between and their typical population is a few hundred or less.

Pollution

Water pollution on the Laptev Sea is relatively low. And the Laptev Sea is largely made up of numerous plants and mines that grow on the Yana, Lena and Anavar rivers. This type of ocean waste is contaminated with phenols, copper and zinc and is constantly washed down rivers in the ocean. Exploration and petroleum mining also spread petrol in the Laptev Sea. Another major pollutant due to rafting activities of the last decades is associated with wood floating and submerged in the Laptev Sea. And due to which the phenol concentration in this type of ocean is higher than that of Arctic water.

Ice

This type of sea is known to be the main source of Arctic sea ice. The Laptev Sea contributes more sea ice than the Chukchi Sea with an average flow of 483,000 km2 per year during the period 1979-1995. Large amounts of sea ice are exported to the Laptev Sea in all months of July, August and September. The formation of ice on this type of Sea results in a huge continuous sheet of ice with a thickness of up to 2 meters in the south-eastern part of the ocean as well as near the coast.

The shoreline on the Laptev Sea ends at a water depth of 20-25 meters and comes at a distance of several kilometers from the shore. And that is why coastal ice of this type of ocean covers about 30% of the ocean area. Ice is flowing northward across the Laptev Sea strip. Its ice sheet on the Laptev Sea usually begins to melt from late May to early June and forms clusters of fractured ice in the northwest and south-east, revealing the remains of mostly mammoths.
