Gulf of Mexico Deep-Water ROV Dive and Oceanographic Data from 2014 Expedition

Oceanographic data and ROV dive-related multimedia from the Gulf of Mexico, collected during the EX1402L3 expedition on NOAA Ship OKEANOS EXPLORER. The dataset covers deep-water areas south and southeast of the Flower Garden Banks National Marine Sanctuary, including Keathley Canyon and the West Florida Escarpment. It was gathered by NOAA_NCEI from April 10 to May 1, 2014.

Use Cases

• Analyze ROV dive video and multimedia to catalog deep-sea biological communities and geological features.
• Study CTD (Conductivity, Temperature, Depth) sensor data to model water column properties in depths less than 500 meters.
• Use bathymetric mapping data from evening operations to characterize seafloor topography on the Sigsbee and West Florida Escarpments.
• Correlate dive locations within the 200nm EEZ with known marine sanctuary boundaries for habitat mapping.
• Investigate temporal patterns from daily ROV dives and nightly mapping operations across the three-week expedition period.

Strengths

• Data collected during a dedicated 22-day NOAA expedition with daily ROV dives.
• Covers multiple distinct geological regions including Keathley Canyon and two major escarpments.
• Includes multiple data modalities: oceanographic sensor data, ROV multimedia, and seafloor mapping.

Limitations

• Dataset is from a single expedition in 2014, limiting temporal analysis and recency.
• Specific sample sizes, row counts, and file formats are unknown from the provided metadata.
• Geographic focus is limited to specific deep-water tracts in the Gulf of Mexico.
