Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 12, 2026 at 08:59 PM | Dataset Last Updated: August 16, 2024 at 12:00 AM
The survey domain, from Cape Flattery, WA to Central Baja California, Mexico, was defined primarily by the modeled distribution of potential habitat for the northern subpopulation (stock) of Pacific Sardine (Zwolinski et al., 2011), with a southern extension permitted by available sampling effort. This area was chosen to encompass the anticipated distributions of the northern stock of Pacific Sardine and the central and northern stocks of Northern Anchovy of the west coasts of the U.S., Canada, and Mexico, but it also spanned portions of the southern stock of Pacific Sardine, Pacific Mackerel, Jack Mackerel, Pacific Round Herring, and Pacific Herring. During summer 2021, the west coasts of the United States and Baja California were surveyed using Lasker, Carranza, Lisa Marie, Long Beach Carnage, and USVs. Compulsory transects were nearly perpendicular to the coast and separated by 10 nmi. The survey began off Cape Flattery, WA and the combination of survey platforms progressed southwards toward Punta Abreojos, MX.
