Ocean Glider Physical Profile Data from Mid-Atlantic Bight Deployment

Physical trajectory data from a Slocum Webb G2 glider equipped with a Deep ISFET pH sensor, CTD, chlorophyll fluorescence, optical backscatter, and dissolved oxygen sensors. The deployment was conducted by Rutgers University's Center for Ocean Observing Leadership in the Mid-Atlantic Bight to sample Atlantic sea scallop and surfclam habitats. Data were collected from October 25 to November 6, 2019, and archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyze cross-shelf gradients in temperature, salinity, and density (CTD data) to study water mass structure.
• Correlate pH sensor measurements with chlorophyll fluorescence and optical backscatter data to assess biogeochemical processes.
• Map glider trajectory and dissolved oxygen levels to identify habitat characteristics for Atlantic sea scallops.
• Model biofouling effects on sensor performance by examining time lag response in pH data over the 15-30 day deployment.

Strengths

• Data integrates measurements from five distinct sensor types (pH, CTD, chlorophyll, backscatter, dissolved oxygen).
• Deployment follows a designed transect across the shelf break and inshore, targeting specific biological habitats.
• Data checked for compliance and aggregated into a single netCDF file by the IOOS National Glider Data Assembly Center.

Limitations

• Temporal coverage is limited to a single 13-day deployment in late 2019.
• Sample size is constrained to one glider (ru30) on one mission.
• Potential for sensor data degradation due to biofouling after 15 days is noted in the mission plan.
