The California Cooperative Oceanic Fisheries Investigations (CalCOFI) are a unique partnership of the California Department of Fish & Wildlife, NOAA Fisheries Service and Scripps Institution of Oceanography. The organization was formed in 1949 to study the ecological aspects of the sardine population collapse off California. Today our focus has shifted to the study of the marine environment off the coast of California, the management of its living resources, and monitoring the indicators of El Nino and climate change. CalCOFI conducts quarterly cruises off southern & central California, collecting a suite of hydrographic and biological data on station and underway. Data collected at depths down to 500 m include: temperature, salinity, oxygen, phosphate, silicate, nitrate and nitrite, chlorophyll, transmissometer, PAR, C14 primary productivity, phytoplankton biodiversity, zooplankton biomass, and zooplankton biodiversity.

Forage species and assemblages in the California Current System
Forage fish and squids have long been recognized to be an important component of the California Current System, beyond the importance of sardine, market squid, anchovy and mackerels that support both large and small fisheries. Studies to date have generally taken a single species approach to forage fish. Assessments and monitoring are currently conducted on discrete species. However it is increasingly recognized that the forage species constitute a dynamic assemblage where species dominance varies over time, outbursts and rapid declines are endemic, and the roles of predator and prey in the ecosystem change both with species abundance and with growth in size within individual species. The complex role of forage needs to be better understood as ecosystem-based management becomes established practice.For the 2013 CalCOFI Symposium we seek wide-ranging contributions on any aspect of forage species and assemblages and their role in the California Current System. Studies utilizing long time series data that apply multidisciplinary approaches are particularly encouraged. The CalCOFI Symposium will be convened by: Sam McClatchie, NOAA Fisheries, SWFSC Vol 54 2013

Available Data
Since 1949, hydrographic and biological data of the California Current System have been collected on CalCOFI cruises. The 61 year hydrographic time-series includes temperature, salinity, oxygen and phosphate observations. In 1961, nutrient analysis expanded to include silicate, nitrate and nitrite; in 1973, chlorophyll was added; in 1984, C14 primary productivity incubations were added; and in 1993, CTD profiling began. >> Hydrographic Data - 1949 to Latest Update
