Description
North Atlantic Ocean data was collected by NOAA Ship OKEANOS EXPLORER during the Atlantic Seabed Mapping International Working Group (ASMIWG) Bermuda Mapping expedition from July 12 to July 31, 2018. The dataset includes shipboard sensor measurements for navigation, meteorology (conductivity, wind, temperature), and oceanography (bathythermograph, sound velocity probe, thermosalinograph), along with profile data from ASVP and XBT casts. It is managed by NOAA's National Centers for Environmental Information (NCEI).
Use Cases
Analyzing water column structure using bathythermograph and thermosalinograph data for temperature and salinity profiles.
Studying marine meteorological conditions through time-series data on wind, conductivity, and temperature.
Mapping seabed topography and sound velocity fields using echo sounder and sound velocity probe measurements.
Conducting oceanographic profile analysis with ASVP (Acoustic Sound Velocity Profiler) and XBT (Expendable Bathythermograph) data.
Correlating navigational data with sensor readings to create geospatially referenced environmental maps.
Strengths
Data covers a specific, focused 20-day expedition in July 2018, providing a coherent snapshot.
Includes a multi-sensor suite capturing navigational, meteorological, and oceanographic parameters simultaneously.
Dataset is hosted by NOAA NCEI, a recognized authoritative source for environmental data.
Limitations
Critical metadata such as row count, file size, and specific column names are unavailable from all sources.
There is a conflict in the 'last updated' date between platforms (2018-07-31 vs. 2026-04-01), creating uncertainty about maintenance.
License information is not provided, which may restrict clear understanding of reuse terms.
