This data set was acquired with a ship-based Echosounder Sonar, Thermosalinograph, Navigation system, Meteorological Sensor, and Fluorometer during Laurence M. Gould expedition LMG1103 conducted in 2011 (Investigator(s): Dr. Dave Leger). These data files are of JGOFS format and include Visible Radiation, Salinity, Temperature, Conductivity, Meteorological, Infrared Radiation, Navigation, Bathymetry, and Fluorescence 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): Palmer Station Winter Turnover.
