ADCP and CTD Oceanographic Data from Gulf of Mexico Cruise

18 sampling stations were occupied during the R/V Pelican cruise PE14-10b from October 17-20, 2013. The dataset contains Acoustic Doppler Current Profiler (ADCP), Conductivity-Temperature-Depth (CTD), Marks, and cruise track data, collected by NOAA NCEI to study hard banks and deep waters west of the Mississippi River. It covers an area from offshore Alabama to west of the Mississippi River delta.

Use Cases

• Analyzing 3D water current velocities and true wind speed patterns in coastal waters.
• Profiling water column properties like practical salinity, thermal temperature, and nitrogen saturation.
• Mapping seafloor depth and studying the relationship between bathymetry and current flow.
• Correlating CTD sensor data (pressure, oxygen) with ADCP current measurements for oceanographic models.

Strengths

• Data is spatially explicit, covering 18 stations across a defined region from approximately 27°58'N to 29°26'N and 87°34'W to 91°01'W.
• Includes multi-instrument data acquisition from ADCP, CTD, and navigation systems, providing correlated physical oceanography measurements.
• Represents a repeated sampling effort of previously studied locations, enabling temporal comparison.

Limitations

• Key metadata is missing, including total row count, specific column names, and exact file formats.
• There is a conflict in the 'last updated' date between sources: one lists 2013-10-20, another lists 2026-03-05.
