    "description": "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.\n\nInstrumentation:\nTime 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.",
