Great Lakes Glider Trajectory Data with Physical Oceanographic Measurements

A 7-day deployment from August 7 to August 14, 2014, collected by a Slocum glider operated by the University of Minnesota Duluth's Large Lakes Observatory. The dataset contains physical oceanographic measurements including temperature, conductivity, salinity, and density from the Great Lakes. It was submitted to the National Centers for Environmental Information via the Integrated Ocean Observing System's National Glider Data Assembly Center.

Use Cases

• Analyze vertical profiles of temperature and density to model thermal stratification and mixing events.
• Map the spatial distribution of salinity and conductivity to trace water mass movements within the Great Lakes.
• Correlate glider trajectory coordinates with physical measurements to study horizontal gradients in water properties.
• Validate regional hydrodynamic models using in-situ time-series data for temperature and salinity.

Strengths

• Data covers a continuous 7-day time-series from a specific glider deployment.
• Includes multiple core physical oceanographic variables: temperature, conductivity, salinity, density.
• Processed and aggregated by the authoritative IOOS National Glider Data Assembly Center (NGDAC).

Limitations

• Dataset is from a single, short deployment in 2014, limiting temporal analysis.
• Spatial coverage is restricted to the specific trajectory of the 'gichigami' glider during the 7-day period.
• Row count and sample resolution are unknown, which may affect statistical power.
