Abstract: |
California Current Ecosystem moorings (CCE1 and CCE2) are surface buoys equipped with interdisciplinary scientific sensors including NOAA PMEL pCO2 system, meteorological sensors (wind, air temperature, air humidity, and air pressure), CTDs (temperature and conductivity), Acoustic Doppler Current Profiler (ADCP, ocean current), oxygen sensor, pH sensor, SUNA (nitrate+nitrite), and FLNTUS (fluorescence). CCE1 is located offshore in the core of the California Current (CalCOFI station 80.80), and CCE2 is closer to shore on the shelf break that is influenced by strong costal upwelling process (CalCOFI station 80.55). CCE moorings measure physical, biological, and chemical variables with temporal resolutions high enough to resolve event-scale phenomena and transmit real-time data to shore. These data are viewed on the website, http://mooring.ucsd.edu/cce and updated every 6 hours. Annual cruises are conducted to recover and redeploy CCE1 (in fall) and CCE2 (in spring) moorings. During the cruises, CTD-Rosette casts are performed with collecting water samples of temperature, salinity, oxygen, DIC, alkalinity, NO2, NO3, Silicate, PO4, NH4, chlorophyll-a, and phaeo pigment. |
