Monitoring Fisheries Resources During a Pandemic

A new CCIEA paper demonstrates the benefits of using a diversified approach to evaluating ecosystem status during data-poor situations.

Human Stressors Erode Climate Resilience in Salmon

Recent research shows California's salmon fishery historically depended less on cold weather and experienced steadier salmon returns despite droughts.

Postdoctoral Scholar Position Available

The CCIEA program is seeking a highly motivated researcher to coordinate and lead an interdisciplinary project focused on Understanding Spatial Interactions Across Ocean-use Sectors in a Changing Climate.

Alaska Large Marine Ecosystems

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.

California Current Ecosystem Status Reporting

Indicators increase our understanding of the California Current and promote sustainable ecosystem management

The CCIEA program presents an annual Ecosystem Status Report to the Pacific Fishery Management Council (PFMC).

Highlights of the 2021-22 California Ecosystem Status Report

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.

Northeast Large Marine Ecosystems

The ocean off the coast of the Northeast United States is divided into three ecologically distinct ecosystems.

New Snapshot of California Current Shows a System of Extremes

Favorable physical conditions over the shelf and slope are providing a good forage base for a variety of marine species, according to the latest California Current Ecosystem Status Report.

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.
