Science Objectives

The California Current is a region of large ecological significance and
known sensitivity to climate forcing. Climate processes, complex
physical systems, carbon and nutrient chemistry, and ecosystem dynamics
all interact to create a rich, societally important, and scientifically
fascinating ocean environment off the west coast of the US. This project
establishes a unique highly multidisciplinary mooring presence in the
southern California Current: two moorings, called CCE(California Current
Ecosystems)-1 and -2 are located in the core of the California Current
and in the upwelling regime on the continental slope, respectively,
along CalCOFI line 80, and measure:
•  atmospheric conditions (CO2, wind, temperature, humidity,
precipitation, irradiance),
•  surface ocean conditions (temperature, salinity, pCO2, O2, pH,
currents, point and integrated measures of phytoplankton 
    chlorophyll content over the euphotic zone, and nitrate supply), and
mixed-layer depth,
•  broad-band active-acoustic observations of zooplankton and fish
biomass over the upper 300m.
The overarching science objectives are to:
1. Study the time variability of physical conditions and its forcing on
time scales from days to years.
2. Observe the impact of physical variability on biogeochemical and
ecosystem processes and conditions.
3. Relate environmental habitat conditions to fisheries quantities.
