This data set was acquired with a ship-based Thermosalinograph, Meteorological Sensor, Fluorometer, Echosounder Sonar, and Navigation system during Nathaniel B. Palmer expedition NBP0404 conducted in 2004 (Chief Scientist: Dr. William Detrich). These data files are of JGOFS format and include Fluorescence, Conductivity, Meteorological, Temperature, Salinity, Infrared Radiation, Visible Radiation, Navigation, and Bathymetry 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): International Collaborative Expedition to Collect and Study Fish Indigenous to Sub-Antarctic Habitats (ICEFISH), and funding was provided by NSF grant(s): OPP01-32032.
