Ocean Glider Trajectory Profile Data from North Atlantic 2020

NCEI Accession 0209332 contains physical trajectory profile data from a glider named 'Bass' deployed by the University of South Florida College of Marine Science. The dataset includes measurements of oceanographic properties like temperature, salinity, conductivity, and density. Data was collected in the North Atlantic Ocean from February 3 to February 21, 2020, and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze temperature and salinity profiles over the glider's trajectory to identify water masses and frontal zones.
• Model density variations from conductivity and temperature data to study ocean stratification and mixing processes.
• Map the three-dimensional geospatial trajectory of the glider against concurrent physical property measurements.
• Validate regional ocean models by comparing simulated temperature and salinity fields against this in-situ time-series data.

Strengths

• Data spans a continuous 19-day deployment period in February 2020.
• Includes multiple core physical oceanographic variables (temperature, salinity, conductivity, density).
• Data underwent quality checks for file convention compliance by the IOOS National Glider Data Assembly Center.

Limitations

• Sample size (number of profiles/rows) is unknown from the description.
• Geographic coverage is limited to a single glider track in the North Atlantic.
• Data is from a single deployment in early 2020, limiting temporal analysis of seasonal or long-term trends.
