NOAA Ship OKEANOS EXPLORER collected multibeam, singlebeam, and sub-bottom profile data during the EX1604 CAPSTONE Wake Island PRIMNM expedition. The cruise operated in the North Pacific Ocean from March 23 to April 13, 2016. NOAA National Centers for Environmental Information processed and archived the data.
Use Cases
- Generate seafloor bathymetry maps from processed multibeam and singlebeam sonar data.
- Analyze sub-bottom profile data to study sediment layers and geological structures near Wake Island.
- Model sound velocity profiles using XBT and Underway CTD (UCTD) casts to calibrate sonar operations.
- Assess temporal changes in oceanographic conditions over the 22-day expedition period.
Strengths
- Data collection was continuous, with mapping operations conducted 24 hours a day.
- Sound velocity casts were taken at intervals not exceeding 6 hours, ensuring frequent calibration.
Limitations
- Specific data volume, row counts, and column details are unknown.
- The dataset's temporal scope is limited to a single 22-day expedition in 2016.
