Several major rivers in Asia flow northward into the Arctic Ocean. These rivers are primarily located in Siberia and serve as vital transportation arteries, though they are frequently blocked by ice.123

The primary rivers that drain into the Arctic include:

Ob River: One of the longest rivers in the world, it flows through western Siberia to the Kara Sea.12
Irtysh River: A major tributary of the Ob.12
Yenisey River: A massive river system that includes the Angara River.23
Lena River: A major river that empties into the Laptev Sea, with a large delta.34
Other rivers: The Yana, Indigirka River, and Kolyma River also flow northward into the Arctic.23

These rivers are characterized by gentle gradients and significant seasonal flooding caused by the thawing of upper reaches before the lower parts.23
