Dataset Overview | National Centers for Environmental Information (NCEI)

Discrete profile dissolved inorganic carbon, total alkalinity, water temperature and salinity measurements collected and assembled from a number of cruises on many different ships for the California Cooperative Oceanic Fisheries Investigations program (CalCOFI) in the North East Pacific Ocean Coastal area from 1983-03-19 to 2021-07-20 (NCEI Accession 0301029)

This dataset includes discrete, profile dissolved inorganic carbon, total alkalinity, water temperature and salinity measurements collected and assembled from a number of cruises on many different ships for the California Cooperative Oceanic Fisheries Investigations program (CalCOFI) in the North East Pacific Ocean Coastal area from 1983-03-19 to 2021-07-20 by the Scripps Institution of Oceanography (SIO). The data were assembled from four distinct datasets on SIO campus and were quality controlled based on observed trends, using World Ocean Circulation Experiment (WOCE) flagging routines.
