Ocean Glider Trajectory with pH and Water Quality Measurements from the Mid-Atlantic Bight

Physical trajectory and sensor data were collected by a Slocum Webb G2 glider during a 60-day deployment from Georges Bank to Atlantic City, NJ. The dataset includes measurements from a Deep ISFET pH sensor, CTD, chlorophyll fluorescence and optical backscatter sensors, and a dissolved oxygen optode. Data were collected by Rutgers University's Center for Ocean Observing Leadership from July to August 2018 and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze the correlation between pH levels and other water properties like temperature and salinity from the CTD sensor.
• Model chlorophyll fluorescence patterns against optical backscatter and dissolved oxygen measurements to study phytoplankton dynamics.
• Map the glider's geospatial trajectory against the temporal series of conductivity and density data to identify water mass boundaries.
• Validate regional ocean models by comparing simulated temperature and salinity profiles against the glider's high-resolution CTD data.

Strengths

• Approximately 60 days of continuous sensor measurements during the deployment.
• Includes multiple concurrent sensor types: pH, CTD, chlorophyll fluorescence, optical backscatter, and dissolved oxygen.
• Data were checked for compliance with netCDF conventions and aggregated by the IOOS National Glider Data Assembly Center.

Limitations

• Sample size and data resolution (e.g., rows, sampling frequency) are unspecified.
• Limited to a single glider deployment in the summer of 2018, restricting temporal and spatial generalizability.
• Potential for sensor drift or calibration issues over the 60-day deployment is not documented.
