Seaglider Physical Oceanographic Measurements from Gulf of Alaska Deployment

Gulf of Alaska measurements from the Seaglider SG011 autonomous underwater vehicle, deployed from December 30, 2004, to February 2, 2005. The dataset contains physical oceanographic data collected along a sawtooth trajectory through the water column. It was collected by the University of Washington and archived by NOAA's National Centers for Environmental Information (NCEI).

Use Cases

• Analyze temperature and salinity profiles to study water mass structure and mixing in the Gulf of Alaska.
• Model depth-averaged currents from glider trajectory and sensor data to understand regional circulation.
• Correlate sensor measurements with the glider's sawtooth dive profile to investigate vertical property distributions.
• Validate regional ocean models using in-situ temperature, salinity, and current measurements from the deployment period.

Strengths

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

Limitations

• Specific row count, column names, and data resolution are unknown.
• Dataset is temporally limited to a specific 35-day deployment in 2004-2005.
