Announcement: All CDIAC ocean data have been transitioned to the new NCEI OCADS web page. Please note that the new OCADS site offers more recent data than the CDIAC ocean collection.
Ocean Carbon Dioxide
Rising atmospheric CO2 and climate change are increasing ocean temperatures and affecting ocean chemistry (e.g., ocean acidification). Monitoring these important changes using ships and other platforms generates large amounts of data from heterogenous sources. Since its inception in 1993, when it became a member of the DOE/NOAA Ocean Carbon Science Team engaged in the World Ocean Circulation Experiment (WOCE), the CDIAC Ocean Carbon Data Management Project has been organizing, quality assuring, documenting, archiving and distributing ocean carbon-related data collected via a number of U.S. and international ocean-observing programs.
CDIAC's ocean carbon data collection includes discrete and underway measurements from a variety of platforms (e.g., research ships, commercial ships, buoys). The measurements come from deep and shallow waters from all oceans. Technological advances make it possible to deliver ocean carbon data real-time but questions about instrument reliability and data quality limit this practice at this moment. All ocean carbon data CDIAC receives come from individual investigators and groups following initial data review.
