Glider Trajectory Profile Data for Gulf of Mexico Hypoxia Study

Physical oceanographic measurements collected by the glider 'Revellie' in the coastal waters of the Gulf of Mexico. The deployment was conducted by Texas A&M University's Geochemical and Environmental Research Group from June 29 to July 15, 2016, to investigate hypoxia. Data was archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze vertical profiles of temperature and salinity to identify water mass boundaries and stratification contributing to hypoxia.
• Map glider trajectory coordinates against density measurements to trace the movement of low-oxygen water masses.
• Correlate conductivity data with salinity profiles to assess sensor performance and data quality for time-series analysis.
• Use the time-stamped depth profiles to study diurnal or short-term variability in physical properties during the summer deployment period.

Strengths

• Data originates from a controlled glider deployment with a specific 17-day mission timeframe.
• Measurements include key physical oceanographic properties: temperature, salinity, conductivity, and density.
• Data underwent quality checks for netCDF convention compliance by the IOOS National Glider Data Assembly Center before archival.

Limitations

• The dataset covers a single, short-duration deployment, limiting analysis of seasonal or interannual trends.
• Specific sample size (number of profiles or rows) and spatial resolution are not provided in the metadata.
• Data is from 2016 and may not reflect current oceanographic conditions in the region.
