Community Permafrost Data

Explore permafrost risks and hazards for rural communities in Alaska based on massive ice, thaw susceptibility, existing infrastructure problems, permafrost occurrence and temperature.

Tool includes detailed explanations for these variables, which are tallied to create a cumulative rating score and risk level.

Historical Sea Ice Atlas

If you live in an Alaska coastal community, hunt or fish in a marine environment, work in shipping or oil and gas, serve with the US Coast Guard, research Arctic ecosystems, or are otherwise interested in Arctic sea ice data and climate change, this atlas is for you.

View maps of sea ice data collected 1850–present from the seas off northern Alaska. You can also download sea ice data for use in your own analyses.

Includes explanations of common sea ice terms and phenomena.

Integrated Arctic Management

What makes an arctic area "important" depends on the perspective and interests of a group. One challenge that managers and policy makers often face is the conflict of interests among groups.

This tool displays geospatial datasets from various environmental, economic, and cultural categories to see where they overlap. This approach illustrates the relative importance of those areas, identifies potential areas of conflict, and highlights gaps in Arctic geospatial data.
