Gulf of Mexico CTD and Transmissivity Data from R/V Gyre

April 1992 data from the Texas Institutions Gulf Ecosystem Research (TIGER) program provides conductivity, temperature, depth, and transmissivity measurements from the Gulf of Mexico east of Galveston. Collected from the ship GYRE using a SEABIRD SBE9 CTD and a 25cm SEATECH transmissometer, the dataset consists of 26 ASCII files with data averaged over 1-meter depth intervals. It is processed into the NODC F022-CTD-Hi Resolution format and submitted by Texas A&M University.

Use Cases

• Analyzing vertical profiles of conductivity, temperature, and depth (CTD) to study water mass structure.
• Investigating light attenuation and particle concentration via transmissivity measurements.
• Calculating derived oceanographic parameters like salinity and density from the core CTD measurements.
• Studying particulate organic carbon distribution in relation to physical water properties.

Strengths

• Data is depth-resolved, averaged over consistent 1-meter intervals for vertical profile analysis.
• Collection used specific, calibrated instruments: a SEABIRD SBE9 CTD and a 25cm SEATECH transmissometer.
• Dataset is processed and formatted according to the standardized NODC F022-CTD-Hi Resolution specification.

Limitations

• The exact column names, row count, and file size are not provided by any source.
• Sources conflict on the last update date: one lists 1992-04-09, another lists 2026-03-05.
