Antarctic Ocean Glider Trajectory Profile Data from 2015

Hourly dive profiles from a Rutgers University ocean glider mission in the Southern Oceans from January 5 to 17, 2015. The dataset contains physical oceanographic measurements collected to study phytoplankton response in the rapidly warming West Antarctic Peninsula. Data was preserved by NOAA's National Centers for Environmental Information after processing by the Integrated Ocean Observing System.

Use Cases

• Analyze temperature and salinity profiles from hourly dives to 100m to model water column stratification.
• Map glider trajectory and density measurements to study ocean current patterns in the Palmer Deep region.
• Correlate conductivity and temperature data with satellite observations to validate regional climate models.
• Investigate temporal changes in physical properties over the 13-day mission to assess short-term ocean variability.

Strengths

• Data covers a specific 13-day mission in a critical Antarctic region, the fastest winter warming place on Earth.
• Measurements include key physical properties: temperature, salinity, conductivity, and density.
• Data underwent quality checks for netCDF compliance by the National Glider Data Assembly Center.

Limitations

• Limited temporal scope: only 13 days of data from a single glider deployment in January 2015.
• Unknown sample size and spatial resolution, as row count and exact column details are not provided.
• Data is nearly a decade old, limiting analysis of recent climatic changes in the region.
