CPS Acoustic Classification
Last updated: 2025-04-15 23:38:08 UTC
Welcome
West Coast coastal pelagic species play an important role in the California Current ecosystem. They’re food sources for marine mammals, sea birds, and larger fish, and they support commercial and recreational fisheries (Zwolinski et al. 2014). Each year the NOAA Southwest Fisheries Science Center surveys the west coast from Baja Mexico to Vancouver Island, Canada to measure the biomass of 5 key coastal pelagic species: Pacific Sardine Sardinops sagax, Northern Anchovy Engraulis mordax, Pacific Mackerel Scomber japonicus, Jack Mackerel Trachurus symmetricus, Pacific Herring Clupea pallasii, and Round Herring Etrumeus acuminatus. The biomass and abundance estimates derived from the survey are used in stock assessment models to support sustainable fisheries.
Document Objective:
This resource demonstrate how the SWFSC uses acoustic data generate biomass estimates of Coastal Pelagic Species. As part of our commitment to open science, reproducibility, and transparency, we provide this metadata guide to compliment our public-domain data. Please consider this resource to be a Living Document. The code in this repository is regularly being updated and improved.
Do not hesitate to reach out (to us at either alice.beittel@noaa.gov or GitHub issues, especially if you find discrepancies in the data or want to suggest improvements to infrastructure. Thank you in advance for your collaboration and partnership with us as we develop our future data universe.
User Resources
The survey produces two reports each year: A Survey Report and a Biomass Report. Each can be found at the NOAA Institutional Repository online
2023 Biomass Report: Distribution, biomass, and demographics of coastal pelagic fishes in the California Current Ecosystem during summer 2023 based on acoustic-trawl sampling
2023 Survey Report: Report on the Summer 2023 California Current Ecosystem Survey (CCES) (2307RL), 17 July to 3 November 2023, conducted aboard NOAA Ships Reuben Lasker and Bell M. Shimada, fishing vessels Lisa Marie and Long Beach Carnage, and three uncrewed surface vessels
