Southern Ocean Glider Trajectory and Physical Profile Data from 2015

Physical trajectory profile data was collected by a University of Delaware glider (ud_134) during a 23-day mission in the Southern Ocean near Anvers Island. The dataset contains measurements of temperature, salinity, conductivity, and density to study coastal processes affecting penguin foraging ecology. Data were assembled by the IOOS National Glider Data Assembly Center and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze temperature and salinity time-series to identify upwelling events and water mass structure near Palmer Deep.
• Map glider trajectory against High Frequency Radar surface current data to study sub-surface flow dynamics.
• Correlate conductivity and density profiles with phytoplankton distribution models to understand foraging habitat for Adélie penguins.
• Use the physical property time-series to validate regional ocean circulation models for the Western Antarctic Peninsula.

Strengths

• Data covers a continuous 23-day deployment from January 24 to February 15, 2015.
• Includes core physical oceanographic variables (temperature, salinity, conductivity, density) for water column profiling.
• Data underwent quality checks for netCDF convention compliance by the IOOS National Glider Data Assembly Center.

Limitations

• Sample size and spatial resolution are unknown due to missing row count and column details.
• Data is from a single glider deployment, limiting generalizability to other regions or time periods.
• The dataset is temporally limited to a specific season in 2015.
