Physical trajectory profile data from glider SG539 deployed by California Institute of Technology in the Drake Passage, Southern Oceans (> 60 degrees South) from 2014-12-08 to 2015-03-19 (NCEI Accession 0178932)

Seaglider dataset gathered as part of the ChinStrAP (Changes in Stratification at the Antarctic Peninsula) study, funded by NSF through OPP-1246460. This dataset contains physical oceanographic measurements of temperature, conductivity, pressure, and estimates of depth-average currents; biological oceanographic measurements of fluorescence, backscatter at 650 nm, and gelbstoff/CDOM (colored dissolved organic matter); and chemical oceanographic measurements of oxygen concentration.

The National Centers for Environmental Information (NCEI) received the data in this archival package 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.
