Great Lakes Glider Measurements of Temperature and Salinity from 2015

Physical oceanographic data collected by a Slocum glider in the Great Lakes from October 5 to 7, 2015. The dataset contains measurements of temperature, conductivity, salinity, and density. It was 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.
• Map the spatial distribution of water density from glider trajectory coordinates and density measurements.
• Correlate conductivity readings with salinity data to assess instrument calibration or water mass characteristics.
• Model physical property gradients over the 3-day deployment period captured in the time-series.

Strengths

• Data aggregated and checked for compliance to netCDF conventions by the IOOS National Glider Data Assembly Center.
• Includes core physical oceanographic properties: temperature, salinity, conductivity, and density.

Limitations

• Dataset covers only a 3-day period in October 2015, limiting analysis of seasonal trends.
• Specific row count, spatial resolution, and data quality flags are unknown from the description.
• Geographic scope is limited to the specific glider deployment path within the Great Lakes.
