Coastal Glider Trajectory Profile Data from Washington-Oregon Shelf

July 22 to August 6, 2011 data comprises physical oceanographic measurements from a Slocum glider deployment in the coastal waters of Washington and Oregon. The dataset was gathered by Oregon Health & Science University's Center for Coastal Margin Observation & Prediction as part of the SATURN observatory, funded by NOAA and NSF. It contains profiles of properties like temperature, salinity, conductivity, and density.

Use Cases

• Characterizing shelf hypoxia dynamics by analyzing dissolved oxygen levels correlated with temperature and salinity profiles.
• Calibrating ocean circulation models using the high-resolution time-series and geospatial trajectory of conductivity, temperature, and depth measurements.
• Studying seasonal water column stratification by examining vertical profiles of density (sigma-t) across the deployment period.
• Supporting fisheries management research by correlating physical property data like temperature with known habitat ranges for key species.

Strengths

• Data spans a continuous 16-day deployment in July-August 2011, a key seasonal period.
• Includes multiple core physical oceanographic variables (temperature, salinity, conductivity, density) per profile.
• Data underwent quality checks for netCDF convention compliance by the IOOS National Glider Data Assembly Center.

Limitations

• Sample size (number of profiles/rows) is unknown from the provided metadata.
• Temporal coverage is limited to a single two-week deployment in 2011, not multi-year.
• Geographic coverage is restricted to a specific trajectory in the Washington/Oregon coastal shelf.
