Joint Archive for Shipboard ADCP Standard Subsets

This data gateway allows users to download the averaged (hourly in time, 10 m in depth) sets, referred to as the JASADCP standard subsets, in ASCII text or NetCDF format.

The unique JASADCP data set is defined by the sonar and cruise. A given cruise could have multiple sonars of varying depth penetration versus resolution characteristics. The unique set is given an ID, called the "SAC_ID". Note in the "cruise" metadata within the SAC_ID summary file, the type of sonar is appended to the cruise ID. If no sonar is given in the cruise metadata, then the default is the NB150, which historically was the most common instrument.
