This data set was acquired with a ship-based Echosounder Sonar, Meteorological Sensor, Thermosalinograph, Fluorometer, and Navigation system during Nathaniel B. Palmer expedition NBP0703 conducted in 2007 (Chief Scientist: Dr. John Anderson). These data files are of JGOFS format and include Meteorological, Conductivity, Fluorescence, Infrared Radiation, Salinity, Visible Radiation, Bathymetry, Temperature, and Navigation 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): Collaborative Research: Controls on Sediment Yields from Tidewater Glaciers from Patagonia to Antarctica, and funding was provided by NSF grant(s): OPP03-38137 and OPP03-38371.
