Ocean Glider CTD Profiles from the Mid-Atlantic Bight, 2018

Physical trajectory profile data was collected by a University of Delaware Slocum glider deployed off the Delaware coast from April 27 to May 7, 2018. The dataset contains conductivity, temperature, and depth (CTD) measurements from profiles to a maximum depth of 100 meters. The National Centers for Environmental Information (NCEI) preserved the data, which was aggregated and submitted by the Integrated Ocean Observing System's National Glider Data Assembly Center (IOOS NGDAC).

Use Cases

• Analyze coastal water column structure based on temperature and salinity profiles.
• Study physical oceanographic property gradients across chlorophyll fronts.
• Validate or calibrate oceanographic models using in-situ CTD measurements.
• Assess sensor performance for new, classified optical instruments in a glider deployment.

Strengths

• Data profiles to a defined maximum depth of 100 meters.
• Contains measurements of core physical oceanographic properties: temperature, salinity, conductivity, and density.
• Data was checked for compliance with a netCDF file convention by the IOOS NGDAC.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2018-05-07 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
