These data are part of the U.S. Antarctic Marine Living Resources (AMLR) Program Operation FREEBYRD. FREEBYRD is a long term program to replace ship-based surveys with autonomous vehicles to estimate Antarctic krill biomass in support of the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR). This delayed dataset contains CTD, oxygen, chlorophyll a, CDOM and optical backscatter measurements.

The National Centers for Environmental Information (NCEI) received the data in this dataset from the Integrated Ocean Observing System's National Glider Data Assembly Center (IOOS NGDAC). The IOOS NGDAC received the data in one or more netCDF files comprising an entire glider deployment. The data are measurements of physical oceanographic properties such as temperature, salinity, conductivity, and density. The IOOS NGDAC checked the files for compliance to their netCDF file convention, aggregated the files into a single netCDF file, and then submitted the file to NCEI for long-term preservation. Data files may be either low resolution real-time or full resolution. Full resolution files are designated as "delayed" in the netCDF file name.
