This data set was acquired with a ship-based Echosounder Sonar, Fluorometer, Meteorological Sensor, Navigation system, and Thermosalinograph during Nathaniel B. Palmer expedition NBP1304 conducted in 2013 (Chief Scientist: Dr. Edward Durbin). These data files are of JGOFS format and include Salinity, Navigation, Bathymetry, Fluorescence, Conductivity, Infrared Radiation, Meteorological, Temperature, and Visible Radiation data. This 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): Seasonal Trophic Roles of Euphausia superba.
