This data set was acquired with a ship-based Meteorological Sensor, Thermosalinograph, Navigation system, Fluorometer, and Echosounder Sonar during Laurence M. Gould expedition LMG1211 conducted in 2012 (Chief Scientist: Dr. Eugene Domack). These data files are of JGOFS format and include Salinity, Visible Radiation, Meteorological, Navigation, Infrared Radiation, Temperature, Fluorescence, Conductivity, 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.
