Detailed Description

In the Arctic, rivers are often thought to freeze completely during winter. Since fish need liquid water to survive, there are few places where they can live. Fish usually inhabit deep river channels and areas where springwater enters a stream. However, this video shows that winter habitat occurs in places we didn't expect, below the ice in the delta of a shallow river.

Under Ice Habitat in Canning River Delta

Arctic National Wildlife Refuge, Alaska April 27, 2019 (0:57)

In the Arctic, rivers are often thought to freeze completely during winter. Since fish need liquid water to survive, there are few places where they can live. Fish usually inhabit deep river channels and areas where springwater enters a stream. However, this video shows that winter habitat occurs in places we didn't expect, below the ice in the delta of a shallow river. The waiving piece of algae shows that water is still flowing, even below many "feet" of ice.
