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. To calibrate and validate CCE mooring timeseries.

NOAA National Centers for Environmental Information custodian bottle bottle any type of water bottle sampling device Generic name for water collection device; usually used to determine temperature, salinity and provide water aliquots for measurement of a wide range of parameters; often referred to by a specific type of water sampling bottle, such as a Nansen or Niskin bottle. coulometer for DIC measurement coulometer for DIC measurement measures dissolved inorganic carbon (DIC) A known amount of seawater is dispensed into a stripping chamber where it is acidified and purged with an inert gas. The amount of CO2 in the resulting gas stream is determined by absorbing the CO2 in an absorbent. The pH of the solution is monitored by measuring the transmittance . CTD CTD Conductivity-Temperature-Depth probe nutrient autoanalyzer nutrient autoanalyzer Laboratory Instrument Nutrient Autoanalyzer is a generic term describing an automated flow-thru system used to conduct analyses of several different nutrients (nitrate, ammonium, orthophosphate, and silicate) simultaneously from a seawater sample.
