Dissolved inorganic carbon, total alkalinity, nutrients, and other variables collected from profile and discrete observations using CTD, Niskin bottle, and other instruments from R/V New Horizon and R/V Robert Gordon Sproul in the U.S. West Coast for calibration and validation of California Current Ecosystem (CCE) Moorings from 2009-12-15 to 2015-04-29 (NCEI Accession 0146024)

This dataset contains inorganic carbon, total alkalinity, nutrients, and other data collected from ships during servicing cruises to the California Current Ecosystem moorings, CCE1 and CCE2. Typically annual cruises are conducted to recover and redeploy CCE moorings. During the cruises, CTD-Rosette casts are performed with collecting water samples of salinity, oxygen, DIC, total alkalinity, nutrients (NO2, NO3, Silicate, PO4, and NH4), chlorophyll-a, and phaeopigment. This data file includes these discrete water sample results and CTD temperature and salinity values where the bottles are taken. 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 coastal 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 can also be viewed on the website http://mooring.ucsd.edu/cce and are updated every 6 hours.
