Gulf of Mexico CTD and Pigment Data from 2013 Research Cruise

The Florida Panhandle Bight and DeSoto Canyon in the Gulf of Mexico are the focus of this dataset. It contains conductivity, temperature, depth (CTD), water quality, and pigment concentration data collected during the R/V Bellows cruise BE-1317 from April 6-8, 2013. The National Oceanic and Atmospheric Administration (NOAA) produced the data, which includes chemical analysis from four Deep-C cruises and pigment reports for 18 samples.

Use Cases

• Analyzing vertical water column profiles using conductivity, temperature, and depth (CTD) measurements.
• Studying phytoplankton pigment composition through columns like chlorophyllide a, peridinin, and zeaxanthin/lutein.
• Investigating nutrient levels and water quality via metrics such as total kjeldahl nitrogen and oxygen saturation.
• Correlating physical oceanographic data (e.g., depth, oxygen sensor readings) with biological pigment concentrations.

Strengths

• Data includes specific chemical and pigment analysis for 18 discrete water samples.
• Covers a defined geographic area (Florida Panhandle Bight, DeSoto Canyon) and time period (April 6-8, 2013).
• Produced by a recognized authority, the National Oceanic and Atmospheric Administration (NOAA).

Limitations

• Key metadata conflicts exist: the 'last updated' date differs significantly between Data.gov (2026-03-06) and NASA Earthdata (2013-04-08).
• Core dataset specifications like row count, file size, and license are not provided by any source.
• The complete list of data columns is unknown, limiting detailed usability assessment.
