The Chukochya River or Bolshaya Chukochya River is a river in the Sakha Republic (Yakutia) of the Russian Federation. It crosses the tundra roughly northeastwards and flows into the Kolyma Gulf of the East Siberian Sea west of the mouths of the Kolyma River. Its mouth is located at 70.1 N, 159.7667 E. Owing to its extreme northerly location the Chukochya River freezes up in early October and remains icebound until June.
The Chukochya River basin is located between the basins of the Alazeya and the Kolyma. There are study sites near the Chukochya River in order to investigate the mineral transformations in the soils affected by permafrost.[1]
The Chukochya or Bolshaya Chukochya River in mainland Eastern Siberia should not be confused with the Chukochya River on Kotelny Island, the largest of the New Siberian Islands.
Ecology
The Kolyma Lowlands, the area where the Chukochya flows, has many lakes and marshes. A great variety of birds, like Siberian cranes, waders and sandpipers, make their habitat in this riverine area.[2]
Fossil insects, early Pleistocene equids and mammoths have been found in the basin of the Chukochya River.[3]
