Farallon Institute conducts seasonal at-sea surveys of seabirds on the CalCOFI (California Cooperative Oceanic Fisheries Investigation) survey grid (above) and on the National Marine Fisheries Service (NMFS) Rockfish Recruitment and Ecosystem Assessment Survey (RREAS) offshore of California and Oregon. These surveys are an integral part of the CalCOFI Long-term Ecological Research (LTER) and Southern California Coastal Ocean Observing System (SCCOOS) programs. FI and other agencies have been collecting these observations since 1987 and these extensive observations, along with concurrently collected hydrographic and plankton data, contribute to understanding the effects of climate variability and change in the southern California Current Ecosystem.
Most at-sea surveys in 2020 were cancelled due to the covid-19 pandemic.
