Gulf of Mexico CTD Hydrographic Data for Instrument Calibration

Gulf of Mexico hydrographic data includes water temperature, salinity, and oxygen parameters collected via CTD from the R/V Pelican. The dataset supports calibration of moored current- and pressure-recording inverted echo sounders deployed during two research cruises. Data collection occurred between June 14 and October 3, 2019, and is managed by NOAA NCEI.

Use Cases

• Calibrating travel time measurements from moored inverted echo sounders using in-situ CTD profiles.
• Analyzing spatial and temporal variations in water temperature and salinity during the 2019 observation period.
• Studying dissolved oxygen levels and other hydrographic parameters in the Gulf of Mexico.
• Validating oceanographic models with field data collected from specific instrument sites visited multiple times.

Strengths

• Data provides specific calibration for moored acoustic instrumentation, indicating a clear applied purpose.
• Covers a defined temporal range from 2019-06-14 to 2019-10-03 across two dedicated research cruises.
• Presence on multiple government platforms (NASA EarthData and Data.gov) signals official curation and importance.

Limitations

• Exact row count, file size, and complete column names are unknown from all sources.
• Conflicting 'last updated' dates exist: one source shows 2019-10-03, another shows 2026-03 05.
• License information is not provided, restricting clear understanding of reuse permissions.
