Gulf of Mexico data from a 2015 research cruise provides vertical profiles of salinity, temperature, dissolved oxygen, and depth. Measurements were collected from near-surface waters to below the euphotic zone at multiple stations using a ship-deployed CTD. The data was submitted by NOAA NCEI for assessing water column structure and validating physical models.
Use Cases
- Analyze vertical structure of the water column by correlating salinity, temperature, and depth profiles.
- Validate physical ocean models by comparing modeled temperature and salinity fields against in-situ CTD measurements.
- Assess dissolved oxygen levels relative to depth and temperature to study hypoxia or water mass characteristics.
- Map spatial variability of oceanographic parameters across the cruise track from 28°N to 29°N and 87.5°W to 88.5°W.
Strengths
- Data covers a defined temporal range from 2015-05-01 to 2015-05-08.
- Includes multiple core oceanographic parameters: salinity, temperature, dissolved oxygen, and depth.
- Spatial coverage is specified for the Viosca Knoll region in the Gulf of Mexico.
Limitations
- Sample size and row count are unknown, limiting statistical assessment.
- Data is from a single 8-day cruise in 2015, offering a temporal snapshot rather than a long-term record.
- Specific data resolution (e.g., measurement frequency with depth) and column details are not provided.
