High-Resolution CTD Profiles from Gulf of Mexico Research Cruise

This dataset contains 18,570 high-resolution Conductivity, Temperature, and Depth (CTD) records from 9 stations in the Gulf of Mexico. Data was collected during the R/V Gyre cruise 94G05 from July 18-20, 1994 as part of the Texas Institutions Gulf Ecosystem Research (TIGER) project. The processed data is stored in the NODC F022 format, providing nearly continuous vertical profiles of oceanographic parameters.

Use Cases

• Analyzing vertical stratification of temperature and salinity in the Gulf of Mexico using depth/pressure, temperature, and salinity columns.
• Calculating water density (sigma-t) for physical oceanography models from the computed density parameter.
• Correlating subsurface ocean conditions with surface meteorological data reported at the time of each cast.
• Examining water clarity or biogeochemical properties using the optional dissolved oxygen or transmissivity measurements.

Strengths

• Contains 18,570 high-resolution records from 9 distinct sampling stations, providing detailed spatial coverage.
• Profiles can report measurements at depth intervals as fine as 1 meter, offering fine vertical detail.
• Data includes cruise metadata, position, date, time, and environmental conditions for contextual analysis.

Limitations

• The exact column names and data schema are not provided by any source platform.
• Sources conflict on the last updated date, with one reporting 1994-07-20 and another reporting 2026-04-01.
