Oceanographic CTD and Fluorescence Data from the Gulf of Mexico

11,448 records of Conductivity, Temperature, Depth (CTD), transmissivity, and fluorescence were collected from 15 casts during a 1993 research cruise. The data was gathered from the ship GYRE as part of the Texas Institutions Gulf Ecosystem Research (TIGER) project. Mr. P.V. Pittman of Texas A&M University submitted the data to NOAA's National Centers for Environmental Information.

Use Cases

• Analyze the relationship between fluorescence and depth to estimate chlorophyll and phytoplankton distribution.
• Model water mass properties using conductivity, temperature, and depth profiles from the 15 casts.
• Correlate transmissivity measurements with other CTD parameters to study particulate matter and turbidity.
• Use the time-series data from October 28 to November 3, 1993, to examine short-term oceanographic variability.

Strengths

• 11,448 individual measurement records provide a detailed vertical profile.
• Data covers multiple parameters (CTD, transmissivity, fluorescence) for each of the 15 casts.
• Collection occurred over a focused 7-day period, enabling synoptic analysis.

Limitations

• Dataset is small in geographic scope, limited to the cruise track of a single ship.
• Data is from 1993 and may not reflect current ocean conditions.
• No column names or sample data are provided to verify structure and units.
