Description
Physical trajectory and sensor data were collected by a Rutgers University Slocum Webb G2 glider during a 27-day deployment from July 17 to August 12, 2019. The dataset includes measurements of temperature, salinity, conductivity, density, chlorophyll fluorescence, optical backscatter, dissolved oxygen, and pH from a cross-shelf transect in the Mid-Atlantic Bight. Data were aggregated and preserved by the NOAA National Centers for Environmental Information (NCEI) via the IOOS National Glider Data Assembly Center.
Use Cases
Analyze cross-shelf gradients in temperature and salinity profiles along the glider's trajectory.
Model relationships between pH measurements, dissolved oxygen concentrations, and chlorophyll fluorescence for biogeochemical studies.
Correlate optical backscatter data with physical density profiles to understand particle distribution.
Map the spatial-temporal distribution of sensor data within specific sea scallop habitat polygons.
Validate oceanographic models using high-resolution time-series conductivity and density data from the deployment period.
Strengths
Integrated multi-sensor dataset includes 8+ physical and chemical variables (e.g., CTD, pH, oxygen, chlorophyll).
Data covers a continuous 27-day time-series from a defined cross-shelf transect.
Data underwent quality checks for netCDF compliance by the IOOS National Glider Data Assembly Center.
Limitations
Specific row counts, sampling resolution, and data completeness for each sensor are not provided.
Potential for sensor biofouling affecting pH sensor response lag, as noted in the deployment plan.
Geographic coverage is limited to a single glider track in the Mid-Atlantic Bight during summer 2019.
Provenance
Source
Rutgers University Center for Ocean Observing Leadership (RU COOL), via IOOS National Glider Data Assembly Center and NOAA NCEI.
Collection Method
In-situ measurements from a Slocum Webb G2 glider equipped with CTD, Deep ISFET pH sensor, WETLabs BB2FL ECO puck, and Aanderaa Optode.
Time Range
2019-07-17 to 2019-08-12
Freshness
Data is from a single deployment ending 2019-08-12; no update frequency stated.
Geography
Mid-Atlantic Bight, near Sandy Hook, NJ, extending to the shelf break north of Hudson Canyon.
Primary data format is netCDF, requiring compatible libraries for analysis. Data aggregation may merge multiple original files; check for consistent time-stamping across all sensor streams.
