Great Lakes Glider Physical Oceanographic Measurements from 2017

Physical trajectory profile data from the glider Gichigami deployed by the University of Minnesota - Duluth's Large Lakes Observatory in the Great Lakes from June 21 to June 26, 2017. The dataset contains measurements of temperature, conductivity, salinity, and density. Data were assembled by the IOOS National Glider Data Assembly Center and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyzing temperature and salinity profiles to identify thermal stratification layers in the Great Lakes.
• Modeling water density variations from conductivity and temperature measurements to study currents.
• Correlating glider trajectory data with physical property measurements for spatial analysis of water masses.
• Validating regional hydrodynamic models using in-situ conductivity and salinity data from a specific 2017 deployment.

Strengths

• Data collected via a Slocum glider, providing high-resolution vertical profiles along a trajectory.
• Measurements include four core physical oceanographic properties: temperature, conductivity, salinity, and density.
• Data processed and checked for compliance with netCDF conventions by the IOOS National Glider Data Assembly Center.

Limitations

• Temporal coverage is limited to a single 6-day deployment in June 2017.
• Geographic scope is confined to the specific trajectory of the glider Gichigami within the Great Lakes.
• Dataset size, row count, and specific sampling resolution are unknown.
