This project includes oral history recordings of residents of northern Alaska talking about sea ice conditions, observations over time, and changes that are occurring. Go to JukeBox

Sea ice extent

Produced by the National Ice Center and updated daily, this layer shows the sea ice edge and delineates the marginal ice zone from fast ice. Fast ice or shorefast ice is anchored to land and relatively stable. The marginal ice zone is the transition between fast ice and the open ocean. It can consist of drifting ice floes, or compact floes at the head of fast ice, but is subject to deformation from ocean processes. This portion of the ice cover is the most biologically diverse and is an essential habitat for marine mammals, fish, and birds.

Sea ice extent data come from the National Ice Center and Polar View.

Utqiaġvik (Barrow) marine radar

The marine radar is mounted on top of the 4-story bank building in downtown Utqiaġvik. It detects sea ice up to 6 miles offshore and acquires a new image every 5 minutes for near real-time results. Ice appears white in the image due to the radar signals reflecting off it. Ridges in the sea ice also appear as bright linear objects, but buildings, fences, and cars on the land can also return strong signals. Darker regions in the image can indicate open water, smooth ice, or shadows. Go to marine radar
