Ecosystem-Based Management on the West Coast

The California Current Large Marine Ecosystem is a dynamic, diverse environment in the eastern North Pacific Ocean spanning nearly 3,000 km from southern British Columbia to Baja California, and includes the United States Exclusive Economic Zone, the coastal land-sea interface, and adjacent terrestrial watersheds.

The California Current Ecosystem is one of the world’s four eastern boundary current ecosystems, which are characterized by high productivity, climatic variability, and high biodiversity.  NOAA Fisheries is proud of our regional partnerships supporting collaborative and ecosystem-based decision making, and of our agency’s pioneering scientific work on the California Current Ecosystem.

NOAA Fisheries’ West Coast Region works with our agency colleagues around the country to develop nationwide policies on ecosystem-based fisheries management and to implement those policies through regional planning efforts.

Sea surface temperature anomaly maps show temperatures above normal in orange and red

About five years ago “the Blob” of warm ocean water disrupted the West Coast marine ecosystem and depressed salmon returns. Now, a new expanse of unusually warm water has quickly grown in much the same way, in the same area, to almost the same size.  NOAA Fisheries is focusing additional monitoring on the new heatwave, designated the Northeast Pacific Marine Heatwave of 2019.
