This data set was acquired with a ship-based Fluorometer, Meteorological Sensor, Navigation system, Echosounder Sonar, and Thermosalinograph during Nathaniel B. Palmer expedition NBP1102 conducted in 2011 (Chief Scientist: Dr. Jim Swift). These data files are of JGOFS format and include Salinity, Conductivity, Fluorescence, Infrared Radiation, Meteorological, Bathymetry, Visible Radiation, Navigation, and Temperature 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): Climate variability and predictability (CLIVAR).
