These data files are of JGOFS (ASCII) format and include Bathymetry, Conductivity, Fluorescence, Infrared Radiation, Meteorological, Navigation, Salinity, Temperature and Visible Radiation data that were processed after acquisitionThis data set was created from calibrated data decimated at 1-minute intervals. Several fields are derived measurements from more than a single raw input. Data were acquired as part of the project(s): Collaborative Research: Pathways of Circumpolar Deep Water to West Antarctica from Profiling Float and Satellite Measurements. Funding was provided by NSF award(s): PLR13-41496.
