Ocean Carbon Data System (OCADS)
(formerly CDIAC-Oceans)

Welcome to the newly founded Ocean Carbon Data System (OCADS), a data management project operated by the NOAA National Centers for Environmental Information (NCEI) at NOAA's headquarters in Silver Spring, Maryland. OCADS was established in January 2017. More...

Ocean Carbon and Acidification Data Portal

Search for individual collection level data sets in the NCEI Ocean Archives, by cruise information (EXPOCODE, cruise name, platform name), observation dates and locations, observation categories, or by matching variables or parameters.

Ocean Carbon Dioxide

Rising atmospheric CO2 and climate change are increasing ocean temperatures and affecting ocean chemistry (for example, ocean acidification). Monitoring these important changes using ships and other platforms generates large amounts of data from heterogenous sources. Since its inception in 1993 as the Carbon Dioxide Information Analysis Center(CDIAC) Ocean Carbon Data Management Project, OCADS has been organizing, quality assuring, documenting, archiving and disseminating ocean carbon-related data collected via a number of U.S. and international ocean-observing programs.

The OCADS ocean carbon data collection includes discrete and underway measurements from a variety of platforms (including research ships, commercial ships, and 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 OCADS receives is provided by individual investigators and groups, following initial data review.
