Northeast Seamounts Expedition Oceanographic and ROV Data

Data from a 2014 expedition aboard NOAA Ship OKEANOS EXPLORER collected oceanographic and meteorological measurements in the North Atlantic Ocean, focusing on seamounts and submarine canyons. The dataset includes shipboard sensor data and information from remotely operated vehicle (ROV) dives conducted both inside and outside the U.S. Exclusive Economic Zone. It was gathered by NOAA's National Centers for Environmental Information (NCEI) to support marine discovery and management interests.

Use Cases

• Analyzing water column properties using thermosalinograph, CTD cast, and bathythermograph data.
• Mapping ROV dive tracks and acoustic survey areas with navigation data to correlate biological observations with bathymetry.
• Studying meteorological conditions during the expedition using wind, air temperature, humidity, and barometric pressure records.
• Investigating sound velocity profiles for acoustic applications and underwater mapping calibration.

Strengths

• Covers a specific month-long expedition with a clear time range from 2014-09-16 to 2014-10-17.
• Includes multi-faceted data from shipboard sensors, ROV operations, CTD casts, and acoustic mapping.
• Targets areas of high discovery potential both within and outside the U.S. EEZ, increasing scientific value.

Limitations

• Critical metadata conflicts exist: the 'last updated' date is listed as both 2014-10-07 and 2026-04-01 across sources.
• No concrete row counts, file sizes, or specific column names are provided by any platform.
