Seaglider Oceanographic Measurements from Washington Coast Deployment

Seaglider SG012 collected temperature, salinity, and depth-averaged current data during a mission from February to June 2005 in the North Pacific Ocean. The buoyancy-driven autonomous underwater vehicle was developed by the University of Washington and deployed by NOAA NCEI. Measurements were taken along a sawtooth trajectory through coastal waters off Washington and Oregon.

Use Cases

• Analyze temperature and salinity profiles to study coastal upwelling dynamics along the Washington/Oregon coast.
• Model depth-averaged current data to understand cross-shelf transport and circulation patterns.
• Validate satellite-derived sea surface temperature measurements with in-situ glider data.
• Calibrate hydrodynamic models using high-resolution spatial-temporal data from the glider's sawtooth trajectory.

Strengths

• Data collected via a specialized autonomous platform designed for missions lasting many months.
• Includes core physical oceanography variables: temperature, salinity, and depth-averaged currents.
• Covers a specific four-month deployment period from 2005-02-07 to 2005-06-08.

Limitations

• Dataset is from a single glider deployment, limiting spatial and temporal generalizability.
• Data recency is low, with the last update in June 2005, potentially limiting relevance to current conditions.
• Specific row count, file formats, and data completeness details are unknown.
