U.S. GLOBEC Georges Bank Data Thesaurus

Revised: November 13, 1997

The following field names, instrument names and protocols are being considered for the U.S. GLOBEC Georges Bank program. This list will be updated as necessary. For further information contact the Data Management office.

The general guidelines used to define field names and data attributes are based on the JGOFS Program although there are differences between the two programs.
