Underwater Glider Physical Oceanographic Measurements in the Yellow Sea

RU22 glider data captures temperature, salinity, conductivity, and density profiles from a week-long deployment in the Yellow Sea during August 2018. Collected by Rutgers University and the Korean Institute of Ocean Science and Technology, this dataset supports the evaluation of ocean models in stratified coastal waters. The National Centers for Environmental Information (NCEI) archives the data for long-term preservation.

Use Cases

• Analyze temperature and salinity gradients to model water column stratification before and during typhoon events.
• Correlate conductivity and density measurements to assess changes in ocean mixing processes over the glider's trajectory.
• Validate regional ocean model forecasts using in-situ physical property data from the Yellow Sea deployment.
• Map the spatial-temporal evolution of oceanographic conditions along the glider path from Jeju Island to the Ieodo Research Station.

Strengths

• Data collected during a targeted scientific mission focused on typhoon-influenced coastal waters.
• Physical measurements (temperature, salinity, conductivity, density) are core variables for oceanographic analysis.
• Archived by the authoritative NOAA NCEI for long-term preservation and access.

Limitations

• Temporal coverage is limited to a single 10-day period in August 2018, lacking seasonal or multi-year context.
• Geographic scope is confined to a specific trajectory in the Yellow Sea, limiting broader regional generalization.
• Exact sample size (rows), data resolution, and completeness of all sensor streams are unknown.
