Seaglider Physical Oceanographic Measurements from Gulf of Alaska Deployment

Physical oceanographic data collected by an autonomous Seaglider vehicle during a mission in the Gulf of Alaska. The dataset was created by the University of Washington and archived by NOAA's National Centers for Environmental Information. Measurements were recorded from November 5 to December 23, 2003.

Use Cases

• Analyze vertical profiles of temperature and salinity along the Seaglider's sawtooth trajectory.
• Calculate depth-averaged currents from the vehicle's navigation and sensor data.
• Model buoyancy-driven glider performance and mission endurance for deployments lasting several months.
• Study seasonal water column structure in the Gulf of Alaska during the November-December period.

Strengths

• Data collected via a purpose-built autonomous platform designed for long-duration, long-range scientific missions.
• Measurements reported in near real-time via wireless telemetry, enabling timely data access.

Limitations

• Dataset is from a single vehicle (SG010) and a single 49-day deployment, limiting spatial and temporal scope.
• Specific row count, column names, and data formats are unknown, complicating initial assessment.
