PACKAGE DESCRIPTION: This dataset includes biological, chemical, discrete sample, physical and profile data collected from DISCOVERY in the North Atlantic Ocean from 1997-08-07 to 1997-09-17 and retrieved during cruise CARINA/74D19970807. These data include ALKALINITY, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), CHLOROPHYLL A, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, PHAEOPHYTIN, PHOSPHATE, Potential temperature (theta), SALINITY, SILICATE, WATER TEMPERATURE and pH. The instruments used to collect these data include CTD and bottle. These data were collected by M. Alvarez and I.S. Aristegui of Commonwealth Scientific and Industrial Research Organization and S Bacon [affiliation unknown] as part of the CARINA/74D19970807, WOCE A25 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.
