Great Lakes Glider Measurements of Temperature and Salinity from 2012

Physical oceanographic measurements collected by a Slocum glider named 'gichigami' in the Great Lakes from June 19 to June 26, 2012. The dataset contains profiles of temperature, conductivity, salinity, and density. Data were gathered by the University of Minnesota Duluth's Large Lakes Observatory and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze vertical profiles of temperature and salinity to identify thermal stratification layers in the Great Lakes.
• Model water density from conductivity and temperature measurements to study mixing processes.
• Map the glider's spatial trajectory against time-series measurements of physical properties.
• Validate regional hydrodynamic models using in-situ salinity and density observations.

Strengths

• Data covers a continuous 8-day deployment period in 2012.
• Includes core physical oceanographic variables: temperature, conductivity, salinity, and density.
• Processed and aggregated into a single netCDF file by the National Glider Data Assembly Center for compliance.

Limitations

• Dataset is from a single, short deployment in 2012, limiting temporal analysis.
• Geographic scope is restricted to the specific path of one glider in the Great Lakes.
• Unknown sample resolution and row count prevents assessment of data density.
