North Atlantic Ocean Glider Physical Profile Data from 2018

Physical oceanographic profile data collected by a Ramses glider deployed by the University of North Carolina at Chapel Hill. The dataset contains measurements of properties like temperature, salinity, conductivity, and density from a single deployment in the North Atlantic Ocean. Data was collected from September 7 to November 20, 2018, and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze vertical profiles of temperature and salinity to study water mass structure and mixing in the North Atlantic.
• Model ocean density from conductivity and temperature measurements to understand stratification and current dynamics.
• Track the glider's spatio-temporal trajectory to correlate physical measurements with specific geographic locations and depths.
• Validate regional ocean models by comparing simulated temperature and salinity fields against this in-situ observational data.

Strengths

• Data originates from a calibrated scientific instrument deployed for a dedicated research program (PEACH).
• Dataset has undergone quality checks for file convention compliance by the IOOS National Glider Data Assembly Center.
• Provides continuous time-series and geospatial coverage for a specific 2.5-month observational campaign.

Limitations

• Dataset represents a single glider deployment, limiting spatial and temporal generalizability.
• Specific sample size, resolution, and data completeness metrics are not provided in the metadata.
• Data is from 2018 and may not reflect current oceanographic conditions.
