Understanding California's dynamic ocean, and assessing anthropogenic impacts on its marine environments
The California Cooperative Oceanic Fisheries Investigations (CalCOFI) is a long-term oceanographic and marine ecosystem monitoring and research program that that surveys the physical, biogeochemical, and biological dynamics of the marine environment with the goal of serving data and science in support of sustainable marine resource management.
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
