This dataset is part of an ongoing research project at the University of California, Santa Cruz.
NCEI Accession 0162187 contains navigational and physical oceanographic data collected at a fixed station at Seaside High School in the Coastal Waters of Washington/Oregon. The Center for Coastal Margin Observation & Prediction collected measurements of conductivity, depth, hydrostatic pressure, latitude, longitude, salinity, and water temperature at frequent intervals from 2004-02-03 to 2008-03-19. Data were assembled by the Northwest Association of Networked Ocean Observation Systems and submitted to the National Centers for Environmental Information.
Seaglider SG104 collected temperature, salinity, depth-averaged current, and other physical data along a sawtooth trajectory through the North Atlantic Ocean. This dataset contains measurements from a single 29-day mission deployed by the University of Washington and archived by NOAA NCEI. The glider operated autonomously from February 14 to March 14, 2008.
From February 25 to March 8, 2008, the Center for Coastal Monitoring and Assessment (CCMA) collected high-resolution multibeam bathymetry and backscatter data from the NOAA Ship Nancy Foster. The mission aimed for 100% seafloor ensonification in high-priority conservation areas within Puerto Rico, including its western coast, Mona Island, and the southern coast of Vieques Island. Data covers mid-water depths ranging from approximately 10 to 500 meters.
Seaglider SG014 collected temperature, salinity, and depth-averaged current data on a sawtooth trajectory through the North Atlantic Ocean. This buoyancy-driven autonomous underwater vehicle was deployed by the University of Washington and NOAA NCEI for a two-week mission from February 14 to 28, 2008. The dataset captures physical ocean properties along the vehicle's gliding path.
