California Current Integrated Ecosystem Assessment


The California Current Integrated Ecosystem Assessment (CCIEA) is an interdisciplinary research effort led by NOAA scientists along the U.S. West Coast. Our goal is to provide science support for ecosystem-based management of the California Current—a complex ecosystem in which natural and human systems are inextricably linked. 

The California Current Ecosystem

The California Current marine ecosystem is a highly productive coastal ecosystem in the northeastern Pacific Ocean. Seasonal upwelling of cold, nutrient-rich water fuels populations of krill, squid, sardines, and other species that are fed upon by larger fishes, seabirds, and marine mammals. The ecosystem supports important fisheries and other activities and provides services for the tens of millions of people living along the West Coast.


Featured Project: Dynamic Ocean Management



Highly migratory species like tunas, sharks and billfishes, and wide-ranging protected species like whales, dolphins and sea turtles are difficult to manage as they cross jurisdictional boundaries that humans impose upon the open seas. Many are top predators that face multiple threats as they migrate seasonally across ocean basins. Such threats include the risk of ship-strikes and accidental catch by fisheries targeting other species. Managing tuna and billfish fisheries while minimizing threats to protected species requires an understanding of how predator distribution and abundance varies with the constantly changing oceanic environment. Read about how the CCIEA team is proposing Dynamic Ocean Management as a way to address this issue.
