NOAA Okeanos Explorer Expedition Oceanographic Data from Atlantic Canyons

NOAA's Okeanos Explorer collected oceanographic data during the EX1404L2 expedition in the North Atlantic Ocean from September 4 to 10, 2014. The mission focused on engineering trials for a remotely operated vehicle (ROV), exploration, and public outreach in continental slope canyons between Rhode Island and Chesapeake Bay. Data includes shipboard sensor readings for navigation, meteorology, and oceanography.

Use Cases

• Analyzing ROV engineering performance during trials in the Lindenkohl canyons.
• Mapping and exploring geological features in the Washington Canyon area.
• Studying meteorological conditions (wind, air temperature, pressure) over the North Atlantic Ocean.
• Investigating oceanographic parameters (temperature, salinity, sound velocity) from shipboard thermosalinograph and probes.
• Supporting outreach and education initiatives using data from Norfolk Canyon and a mid-Atlantic gas seep site.

Strengths

• Data covers multiple distinct mission objectives: engineering trials, exploration, and outreach across several canyons.
• Includes a multi-sensor suite capturing navigation, meteorological, and oceanographic parameters.
• Dataset is hosted on multiple government platforms (Data.gov and NASA EarthData), indicating institutional importance.

Limitations

• Specific row counts, file sizes, and a complete column list are unavailable from all sources.
• Conflicting last update dates exist between platforms (2014-09-10 on NASA EarthData and 2026-04-01 on Data.gov).
• License and author information are not provided.
