    dct:description "These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, pelagic monitoring component. This dataset consists of multiple tables (one for each year of sampling), providing several physical oceanographic measures at sampling stations throughout Prince William Sound, Alaska. Data were collected with a Seabird Electronics conductivity-temperature-depth (CTD) profiler equipped with various sensors and data were processed with Seabird Electronics software. Data include: date, time, latitude, longitude, depth, conductivity, temperature, salinity, turbidity, fluorescence, density, oxygen, pH, Par, sound velocity, beam attenuation and transmission at one meter increments." ;
