CTD and sound speed profile data acquired in support of hydrographic multibeam surveys to meet NOAA/NOS, Office of Coast Survey charting requirements

Metadata Updated: February 1, 2025

Multiple sensors are used to acquire sound speed profiles in the survey areas assigned to the ships and navigation response teams. Some vessels have CTDs and acquire conductivity, temperature and depth profiles, which are then converted to sound speed profiles. In these cases, the files being submitted to the database will provide all four data profiles. Some vessels have direct sound speed instruments. In these cases, there will only be a sound speed profile provided for inclusion in the database.
