Great Lakes Glider Trajectory Profiles for Temperature and Salinity

Physical oceanographic data from a Slocum glider deployment in the Great Lakes, collected by the University of Minnesota Duluth's Large Lakes Observatory. The dataset contains measurements of temperature, conductivity, salinity, and density. It was archived by NOAA's National Centers for Environmental Information (NCEI) from a deployment spanning June 28 to July 5, 2013.

Use Cases

• Analyze vertical temperature and salinity profiles to identify thermocline depth and stratification.
• Map glider trajectory paths against density measurements to study water mass movement.
• Model conductivity-to-salinity relationships for calibration of sensor data.
• Correlate time-series measurements of physical properties with seasonal lake dynamics.

Strengths

• Data spans a continuous 8-day deployment period in 2013.
• Contains core physical oceanographic variables: temperature, conductivity, salinity, and density.
• Processed and aggregated by the Integrated Ocean Observing System's National Glider Data Assembly Center (IOOS NGDAC) for compliance.

Limitations

• Single deployment from 2013, temporal coverage is limited to one week.
• Geographic scope is restricted to the specific Great Lakes region of the glider track.
• Exact row count, spatial resolution, and data completeness metrics are unknown.
