NOAA Ship Okeanos Explorer collected oceanographic data in the South Pacific Ocean from March 7 to 29, 2017. The expedition focused on marine protected areas including the Phoenix Islands Protected Area and the Pacific Remote Islands Marine National Monument. Data collection utilized deep-water mapping systems and a remotely operated vehicle.
Use Cases
- Map seafloor bathymetry using Kongsberg EM302 multibeam sonar data.
- Analyze sub-bottom sediment layers with Knudsen 3260 chirp profiler sonar records.
- Study water column current profiles from Teledyne Acoustic Doppler Current Profiler measurements.
- Correlate ROV Deep Discoverer dive observations with concurrent multibeam sonar mapping data.
- Investigate fisheries acoustics using EK60 split-beam sonar data collected during the expedition.
Strengths
- Data collected over a 23-day continuous expedition in 2017.
- Operations covered multiple designated marine protected areas for focused study.
- Utilized a suite of specialized deep-water mapping and profiling systems.
Limitations
- Sample size and specific row/column counts are unknown.
- Data is from a single expedition in 2017, limiting temporal analysis.
- Geographic scope is specific to the South Pacific cruise track.
