This data set was acquired with a ship-based Kongsberg EM120 Multibeam Sonar system, ODEC Bathy2000 Echosounder Sonar, Meteorological Sensor, Turner Designs 10-AU-005 Fluorometer, Navigation system, Thermosalinograph, and Fluorometer during Nathaniel B. Palmer expedition NBP0403 conducted in 2004 (Chief Scientist: Dr. Steve Cande; Investigator(s): Dr. Steve Cande and Dr. Joann Stock). These data files are of JGOFS format and include Navigation, Meteorological, Conductivity, Fluorescence, Infrared Radiation, Bathymetry, Visible Radiation, Temperature, and Salinity 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): Late Cretaceous and Cenozoic Reconstructions of the Southwest Pacific, and funding was provided by NSF grant(s): OPP01-26334, OPP01-26340, and ANT03-38317.
