PH, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using CTD, bottle and other instruments from GARCIA DEL CID in the North Atlantic Ocean from 1984-02-18 to 1984-03-07 (NCEI Accession 0143392)
- PACKAGE DESCRIPTION: This dataset includes discrete sample and profile data collected from GARCIA DEL CID in the North Atlantic Ocean from 1984-02-18 to 1984-03-07 and retrieved during cruise CARINA/29GD19840218. These data include CHLOROPHYLL A, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, Potential temperature (theta), SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE, pH, phosphate and silicate. The instruments used to collect these data include CTD and bottle. These data were collected by F. Pérez of Commonwealth Scientific and Industrial Research Organization, Aida F. Ríos of Instituto de Investigaciones Marinas de Vigo and F. Fraga [affiliation unknown] as part of the CARINA/29GD19840218 data set. The CARINA (CARbon dioxide IN the Atlantic Ocean) data synthesis project is an international collaborative effort of the EU IP CARBOOCEAN, and U.S. partners. It has produced a merged internally consistent dataset of open ocean subsurface measurements for biogeochemical investigations, in particular, studies involving the carbon system. The original focus area was the North Atlantic Ocean, but over time the geographic extent expanded and CARINA now includes data from the entire Atlantic, the Arctic Ocean, and the Southern Ocean.
