Coastal Glider Trajectory Profile Data for Shelf Hypoxia Study

Physical oceanographic measurements from a Slocum glider deployment in the coastal waters of Washington and Oregon. The dataset captures temperature, salinity, conductivity, and density profiles from a single glider unit (unit_251) during a 20-day mission in summer 2013. Data were collected by Oregon Health & Science University's Center for Coastal Margin Observation & Prediction, archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze vertical profiles of temperature and salinity to characterize shelf hypoxia events for fisheries management.
• Use conductivity and density measurements to study water mass structure and mixing in the Washington/Oregon coastal region.
• Calibrate regional ocean circulation models using the high-resolution time-series and geospatial trajectory data from the glider.
• Investigate seasonal (April-September) glider operation patterns by correlating physical property data with deployment timing.

Strengths

• Data from a dedicated 20-day glider deployment provides continuous temporal coverage.
• Includes core physical oceanographic variables (temperature, salinity, conductivity, density) for water column analysis.
• Data checked for compliance with netCDF conventions and aggregated by the IOOS National Glider Data Assembly Center.

Limitations

• Sample size is limited to a single glider unit (unit_251) and one summer deployment.
• Data is from 2013 and may not reflect current oceanographic conditions.
• Unknown row count and specific spatial resolution limit reproducibility assessments.
