Biological, chemical, optical, and physical observations collected aboard the Alaska marine highway system ferry TUSTUMENA in the Gulf of Alaska from 2004-09-15 through 2008-11-06 (NCEI Accession 0070122)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 02:00 AM | Dataset Last Updated: January 19, 2011 at 12:00 AM
An oceanographic measurement system aboard the Alaskan ferry Tustumena operated for four years in the Alaska Coastal Current with funding from the Exxon Valdez Oil Spill Trustee Council, the North Pacific Research Board and the National Oceanic and Atmospheric Administration. Sampling water from the ships sea chest at 4 m, the underway system measured: (1) temperature and salinity basic physical variables, (2) nitrate - an essential phytoplankton nutrient, (3) chlorophyll fluorescence, an indicator of phytoplankton concentration, (4) colored dissolved organic matter (CDOM) fluorescence, an indicator of terrestrial runoff, and (5) optical beam transmittance, an indicator of suspended sediment. Instrumentation: Time series instruments used on this underway system are listed by manufacturer. Data are processed using software provided by the manufacturers of the instruments along with recent calibration files when appropriate. Post processing was via Ferret data visualization and analysis software.
