The WOCE (World Ocean Circulation Experiment) Carbon Data Management Project started in 1993 when CDIAC (the Carbon Dioxide Information Analysis Center) became a member of the DOE/NOAA Ocean Carbon Science Team with data management and permanent archive responsibilities for the WOCE CO2 measurements. The WOCE was a major component of the World Climate Research Program with the overall goal of better understanding the ocean's role in climate and climatic changes resulting from both natural and anthropogenic causes. The CO2 survey took advantage of the sampling opportunities provided by the WHP cruises during this period between 1990 and 1998. The final data set covers approximately 170 WOCE cruises.
