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.
How To Use This Website
- If you are interested in submitting data please read the submission guide or head straight to the submission tool.
