Seaglider Oceanographic Measurements from Washington Coast 2008

Seaglider SG119 data from NOAA NCEI includes temperature, salinity, and depth-averaged current measurements collected via an autonomous underwater vehicle. The dataset covers a deployment period from September 15, 2008, to January 7, 2009, in the coastal waters of Washington and Oregon. The glider was developed by the University of Washington's School of Oceanography and Applied Physics Laboratory.

Use Cases

• Analyze temperature and salinity profiles over time to study seasonal changes in coastal waters.
• Model depth-averaged current data to understand coastal circulation patterns during the fall and winter.
• Validate oceanographic models using in-situ physical measurements from an autonomous glider platform.
• Correlate glider trajectory data with measured variables to assess spatial variability in the North Pacific Ocean.

Strengths

• Data collected over a continuous 115-day mission from a single, calibrated platform.
• Includes core physical oceanography variables: temperature, salinity, and depth-averaged currents.

Limitations

• Exact row count, column names, and data resolution are unknown from the metadata.
• Dataset is temporally limited to a single season from late 2008 to early 2009.
• Geographic scope is restricted to a specific coastal region of the Pacific Northwest.
