Coastal Glider Trajectory Data for Hypoxia Monitoring off Washington and Oregon

Slocum glider unit_092 collected physical oceanographic measurements in the coastal waters of Washington and Oregon from May 17 to June 2, 2009. The dataset includes properties like temperature, salinity, conductivity, and density, gathered by the Oregon Health & Science University's Center for Coastal Margin Observation & Prediction. Data were archived by NOAA's National Centers for Environmental Information after processing by the IOOS National Glider Data Assembly Center.

Use Cases

• Analyze temporal patterns of temperature and salinity profiles to characterize seasonal hypoxia onset.
• Map spatial gradients of density and conductivity to identify water mass boundaries on the continental shelf.
• Calibrate regional ocean circulation models using the high-resolution vertical trajectory and physical property data.
• Correlate glider-measured oceanographic variables with fisheries data to assess habitat suitability.

Strengths

• Data covers a 17-day continuous deployment in a key coastal region.
• Includes multiple core physical oceanographic variables (temperature, salinity, conductivity, density).
• Processed and aggregated into a single netCDF file compliant with IOOS NGDAC conventions.

Limitations

• Temporal coverage is limited to a single, short deployment in spring 2009.
• Sample size and specific row/column counts are unknown from the provided metadata.
• Geographic scope is restricted to one glider track in the Washington/Oregon coastal waters.
