Laptev Lake

from Wikipedia, the free encyclopedia

The Laptev Sea is north of Russia or Asia lying marginal sea of the Arctic Ocean . It is named after the Russian researcher Chariton Prokofjewitsch Laptew and his cousin Dmitri Jakowlewitsch Laptew .


The Laptev Sea extends from about 72 ° latitude northwards to the permanent ice border of the Arctic Ocean at about 80 °, or from 110 ° to 140 ° long and occupies an area of ​​approx. 714,000 km² at an average depth of 578 meters. The greatest depth determined to date is 2980 meters below sea level.

Adjacent seas of the Laptev Sea are in the west the Kara Sea , to which the Wilkizki Strait south of Severnaya Zemlya leads, and in the east the East Siberian Sea , which is located east of the New Siberian Islands .

There are only a few settlements on the Laptev Sea, including the port of Tiksi .

Permafrost areas from earlier exposure to cold air lie under the Laptev Sea .


Topographically , it is bounded by the Taimyr Peninsula in the west, the Severnaya Zemlya archipelago in the northwest and the New Siberian Islands in the east. Islands that are entirely within the Laptev Sea are (all uninhabited):


In this often icy sea of the largest current flows in Eastern Siberia , the Lena , with her big Lena Delta . Much further to the west - on the southeast coast of the Taimyr Peninsula - is the Chatanga Gulf as the mouth of the Chatanga . These two opposite mouth shapes already reveal a lot about the changing flow conditions that the Siberian currents cause in the Laptev Sea, and they are partly responsible for the local climate . About 80 km west of the Lena, the Olenjok flows into the Laptev Sea, further to the west is the Anabar estuary with the Anabar Bay on the Anabar Gulf , and in the far east lies the Jana , which, like the Lena, forms an estuary delta.
