Eastern Pacific Oceanographic and Mapping Expedition Data from 2017

A 2017-10-16 to 2017-11-11 dataset from NOAA Ship OKEANOS EXPLORER contains oceanographic, meteorological, and navigation data collected during a mapping expedition in the North Pacific Ocean. It was gathered by the NOAA National Centers for Environmental Information (NCEI) using the ship's deep water mapping system, sensors, and Acoustic Doppler Current Profilers (ADCP). The data covers the Clarion-Clipperton Fracture Zone and the transit between Honolulu, Hawaii and Balboa, Panama.

Use Cases

• Analyze water column structure by correlating thermosalinograph and bathythermograph data with Acoustic Doppler Current Profiler (ADCP) measurements.
• Model regional weather patterns by examining time-series of meteorological data including wind, air temperature, relative humidity, and barometric pressure.
• Map seafloor features and validate bathymetric models using data from the ship's deep water mapping system integrated with navigation data.
• Study sound velocity profiles for underwater acoustics applications using data from the dedicated sound velocity probe.

Strengths

• Data collection over a 27-day continuous expedition in October-November 2017.
• Multi-sensor acquisition including navigation, meteorological, and multiple oceanographic instruments.
• Real-time data transfer and control capabilities via high-bandwidth satellite were employed during collection.

Limitations

• Specific sample size, row count, and data volume are unknown.
• Limited to a single expedition's temporal scope and geographic track in the North Pacific.
• Data completeness and sensor calibration details for the specific cruise are not provided.
