Seaglider Physical Oceanographic Measurements from Cascadia 2008 Deployment

North Pacific Ocean coastal waters of Washington and Oregon contain physical oceanographic data collected by Seaglider SG030 from September 15 to 19, 2008. The dataset includes measurements of temperature, salinity, and depth-averaged current along a sawtooth trajectory. It was collected by the University of Washington and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze temperature and salinity profiles to study water column stratification and mixing processes.
• Calculate depth-averaged currents to investigate coastal circulation patterns near Washington and Oregon.
• Correlate sensor measurements with the glider's sawtooth dive trajectory to assess spatial data coverage.
• Validate regional ocean model outputs for September 2008 using in-situ temperature and salinity observations.

Strengths

• Data collected via a specialized autonomous underwater vehicle designed for long-duration scientific missions.
• Includes core physical oceanographic variables: temperature, salinity, and depth-averaged current.
• Provides geospatial and temporal context for a specific 5-day deployment in a defined coastal region.

Limitations

• Limited temporal coverage of only 5 days in September 2008, insufficient for seasonal or interannual analysis.
• Specific sample size, data resolution, and column details are unknown from the provided metadata.
• Data is over 15 years old, which may limit relevance for studying current oceanographic conditions.
