PACKAGE DESCRIPTION: This dataset includes chemical, discrete sample, physical and profile data collected from GARCIA DEL CID in the North Atlantic Ocean from 1982-11-10 to 1982-11-19. These data include 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 and Aida F. Ríos and F. Fraga of Institute of Marine Research Vigo as part of the CARINA/29GD19821110 data set. CDIAC associated the following cruise ID(s) with this data set: CARINA/29GD19821110 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.
