Great Lakes Glider Trajectory Profile Data for Physical Oceanography

July 3-5, 2017 data from a Slocum glider deployment in the Great Lakes, capturing physical oceanographic profiles. 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 thermocline depth and stratification strength.
• Model water density from conductivity and temperature measurements to study internal wave activity.
• Correlate glider trajectory data with spatial maps of water properties for regional hydrodynamic studies.

Strengths

• Data spans a continuous 3-day deployment period for temporal analysis.
• Includes four core physical oceanographic variables (temperature, conductivity, salinity, density) per profile.
• Processed and aggregated by the Integrated Ocean Observing System's National Glider Data Assembly Center for consistency.

Limitations

• Limited temporal coverage to a single 3-day period in July 2017.
• Spatial coverage is restricted to the specific glider track within the Great Lakes.
• Unknown sample size and vertical resolution of the profiles.
