Welcome to the CCHDO
Learn About CCHDO
The CCHDO's primary mission is to be a repository and distribution center for CTD and Hydrographic data sets of the highest possible quality. These data are a product of WOCE, CLIVAR and numerous other oceanographic research programs -- past, present and to come. Whenever possible we provide these data in three widely-used formats: WHP-Exchange (which we recommend for data submissions to the CCHDO), WOCE, and netCDF.
The CCHDO also manages submission of non-public CTD data to be used only for calibration of profiles from the global Argo float program.
This site is funded by the National Science Foundation.
