Observing the California Current since 1949 to understand and predict the effects of climate change on marine ecosystems
The California Cooperative Oceanic Fisheries Investigations (CalCOFI) is an oceanographic and marine ecosystem research program off the coast of California that holistically studies the physics, biogeochemistry, and biology of the marine environment to inform the sustainable management of marine resources in the context of climate change.

Oceanographic Data
Temperature, salinity, dissolved oxygen, nutrients, dissolved inorganic carbon (DIC) and many more environmental variables from CTD sampling and underway systems

Marine Ecosystem Data
Marine mammals, seabirds, fish eggs & larvae, zooplankton, phytoplankton, primary production, bacterioplankton, and eDNA from net tows, CTD sampling, and underway systems
