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.

This interactive graphic provides an overview of the key messages and findings of the 2021-22 California Current Ecosystem Status Report (ESR). Hover over each indicator icon - or the associated indicator from the menu on the right, and click to learn more about it and see the data. Icon color is used to represent favorable (blue) or unfavorable (brown) conditions. This is a product led by the California Current Integrated Ecosystem Assessment (CCIEA) program.

What is a marine heatwave?

Marine heatwaves, or MHWs, occur when ocean temperatures are much warmer than usual for an extended period of time; they are specifically defined by the difference between the current temperature and the expected temperature for a specific location and time of year [1]. MHWs are a growing field of study worldwide because of their effects on ecosystem structure, biodiversity, and regional economies.

A Physics-to-Fisheries Management Strategy Evaluation for the California Current System

Future Seas is a project exploring potential impacts of climate change on the swordfish, albacore, and Pacific sardine fisheries in the California Current System. A suite of dynamical, statistical, and conceptual models is being applied to explore future scenarios in an “end-to-end” framework spanning physical changes to socio-economic consequences, and to evaluate uncertainty associated with individual elements of the modeling framework.
