Alaska Sub-regions

ak-ebs-use-01.jpg

The Alaska region is made up of 5 distinct ecosystems: the Gulf of Alaska (GOA), the Aleutian Islands (AI), the Eastern Bering Sea (EBS), the Beaufort Sea, and the Chukchi Sea (Alaskan Arctic). These support extensive high-value commercial fisheries, indigenous community’s subsistence uses, oil and gas development, and many other economic and cultural uses. Each of these regions is distinct in ecosystem structure and function and human activity.
