Alaska boasts 32 ecologically distinct regions, including five large marine ecosystems:

  • Gulf of Alaska
  • Eastern Bering Sea
  • Aleutian Islands
  • Beaufort Sea
  • Chukchi Sea

In many coastal communities, aquaculture creates jobs that support working waterfronts and economic development. For instance, the southeastern Bering Sea supports some of the most valuable commercial fisheries in the world for salmon and Walleye pollock.

These waters will likely be affected by climate-related changes, such as warming oceans, increasing acidification, and rising seas. NOAA is working with partners to understand and respond to changing conditions to help minimize impacts to the environment.
