California Current Integrated Ecosystem Assessment The California Current Integrated Ecosystem Assessment provides a science-based synthesis of oceanographic, biological, and socioeconomic information for the California Current region, informing decision-making for fisheries and conservation across the United States West Coast. Drawing on partnerships among federal agencies such as the National Oceanic and Atmospheric Administration, research institutions like the Scripps Institution of Oceanography and the Monterey Bay Aquarium Research Institute, and regional management bodies including the Pacific Fishery Management Council and the West Coast Governors' Agreement on Ocean Health, the assessment integrates datasets to support policy under statutes such as the Magnuson-Stevens Fishery Conservation and Management Act and directives from the Executive Office of the President of the United States.

Overview

The assessment synthesizes physical drivers such as upwelling associated with the California Current and climate patterns including the El Niño–Southern Oscillation, Pacific Decadal Oscillation, and North Pacific Gyre Oscillation with biological indicators spanning plankton from studies at the Hopkins Marine Station, forage fish surveys conducted by the National Marine Fisheries Service, and marine mammal monitoring by the National Marine Mammal Laboratory. It links habitat maps from the California Department of Fish and Wildlife and benthic surveys from the NOAA National Centers for Environmental Information to socioeconomic analyses relevant to the California legislature, fishing communities in Monterey, ports such as San Francisco Bay and Port of Los Angeles, and conservation priorities advocated by organizations like the Nature Conservancy and Monterey Bay Aquarium.

Early regional ecosystem work built on oceanographic expeditions by the U.S. Coast Survey and observational programs at the Scripps Institution of Oceanography and UCLA Institute of the Environment and Sustainability, later formalized through interagency reviews involving the National Research Council and workshops convened by the North Pacific Marine Science Organization (PICES). The Integrated Ecosystem Assessment approach emerged from frameworks developed by the U.S. Commission on Ocean Policy and implementation guidance from the U.S. Integrated Ocean Observing System, with pilot assessments supported by grants from the National Science Foundation and cooperative agreements with the Pacific States Marine Fisheries Commission and academic partners including University of Washington, Oregon State University, and University of California, Santa Cruz.

Primary objectives align with mandates under the Magnuson-Stevens Fishery Conservation and Management Act and regional conservation plans endorsed by the West Coast Governors' Agreement on Ocean Health: to characterize ecosystem status, assess risks to living marine resources, and evaluate management strategies for species such as Chinook salmon, Dungeness crab, and Pacific sardine. The framework integrates indicators from physical modeling centers like the NOAA Geophysical Fluid Dynamics Laboratory and biodiversity inventories associated with the Smithsonian Institution and establishes operational objectives used by bodies including the Pacific Fishery Management Council and regional Marine Protected Area networks.

Methods combine remote sensing from satellites operated by NASA and NOAA satellites with in situ observations from programs such as the California Cooperative Oceanic Fisheries Investigations and tagging studies run by the Tagging of Pacific Predators program. Biological data derive from trawl surveys by the Alaska Fisheries Science Center and plankton monitoring through the Continuous Plankton Recorder Survey, while socioeconomic inputs use fisheries landing statistics from the National Marine Fisheries Service and economic analyses from institutions like the Public Policy Institute of California. Modeling approaches employ ecosystem models used at the NOAA Southwest Fisheries Science Center, statistical frameworks endorsed by the Intergovernmental Panel on Climate Change, and decision-support tools shared with the U.S. Fish and Wildlife Service.

Assessments have documented recent shifts in species distributions linked to anomalous warming events such as the 2014–2016 marine heatwave and influenced by El Niño episodes, with documented impacts on predators including California sea lions, seabirds studied at Point Reyes National Seashore, and commercially important species like Pacific hake and anchovy. The analysis highlights vulnerability of kelp forests adjacent to Channel Islands National Marine Sanctuary, changes in primary productivity measured near Monterey Bay National Marine Sanctuary, and socioeconomic consequences for fishing communities in Newport, Oregon and Half Moon Bay exposed in reports co-authored with the Economic Development Administration.

Results feed into harvest control rules implemented by the Pacific Fishery Management Council, recovery planning under the Endangered Species Act for populations such as Southern Resident killer whale and Coho salmon, and spatial planning for marine protected areas coordinated with the California Department of Fish and Wildlife and federal entities like the National Marine Sanctuary System. The assessment underpins climate adaptation planning by the California Ocean Protection Council and informs emergency responses to events declared by offices such as the Governor of California and federal emergency agencies.

Collaborative governance involves federal agencies including the National Oceanic and Atmospheric Administration and the U.S. Geological Survey, state partners such as the California Natural Resources Agency, academic institutions like Stanford University, University of California, Davis, and non-governmental organizations including the Monterey Bay Aquarium and Environmental Defense Fund. International and multiregional collaboration draws on expertise from bodies such as PICES, the Western and Central Pacific Fisheries Commission for comparative frameworks, and interagency convenings hosted by the White House Office of Science and Technology Policy.
