Gulf of Mexico Oceanographic Expedition Data from NOAA Ship Okeanos Explorer

A 23-day expedition in the Gulf of Mexico from November 29 to December 21, 2017 collected multidisciplinary oceanographic data. The dataset includes navigational, meteorological, and oceanographic sensor data, along with CTD profiles, ADCP currents, digital imagery, and specimen logs. It was gathered by NOAA Ship Okeanos Explorer and archived by NOAA NCEI.

Use Cases

• Analyze water column structure by correlating bathythermograph and processed CTD data with location.
• Model near-surface oceanographic conditions using thermosalinograph, meteorological, and navigational data.
• Characterize current patterns in the Gulf of Mexico from Acoustic Doppler Current Profiler (ADCP) time-series.
• Link biological or geological specimen logs with event logs and digital imagery for habitat studies.
• Validate sound speed models using data from the sound velocity probe and profile data (ASVP, XBT).

Strengths

• Data spans a focused 23-day research expedition with consistent methodology.
• Includes a diverse suite of sensor types: meteorological, oceanographic, acoustic, and imagery.

Limitations

• Dataset is a single snapshot from late 2017, limiting analysis of temporal trends.
• Sample size and spatial coverage are confined to the specific cruise track of the expedition.
• Data completeness and granularity for individual sensor streams are unknown.
