SEAMAP Oceanographic CTD Data from Gulf of Mexico 2001-2012

NOAA's Southeast Area Monitoring and Assessment Program (SEAMAP) collected temperature, salinity, and dissolved oxygen measurements via CTD and bottle casts from the NOAA Ship OREGON II in the Gulf of Mexico. The dataset represents a State/Federal/university collaborative effort for fishery-independent data collection and spans the period from 2001 to 2012. It is managed by the National Oceanic and Atmospheric Administration, Department of Commerce.

Use Cases

• Analyzing long-term trends in Gulf of Mexico water column properties like temperature and salinity.
• Correlating dissolved oxygen levels with fishery-independent survey data for habitat suitability studies.
• Validating regional oceanographic models using in-situ CTD and bottle cast measurements from 2001-2012.

Strengths

• Provides a multi-year time series from 2001 to 2012, enabling longitudinal analysis.
• Data is collected via a collaborative State/Federal/university program (SEAMAP), suggesting standardized methods.

Limitations

• Specific row counts, column names, and dataset size are unknown across all sources.
• Conflicting last updated dates: Data.gov lists 2026-03-05, while NASA Earthdata lists 2012-07-13, raising questions about maintenance.
