Oceanographic Survey of Pacific Remote Islands Marine National Monument

NOAA Ship Okeanos Explorer collected oceanographic data in the South Pacific Ocean from January 18 to February 10, 2017. The expedition focused on mapping within the Pacific Remote Islands Marine National Monument and the Phoenix Islands Protected Area. Data was gathered using deep-water mapping systems including multibeam sonar, fisheries sonars, and sub-bottom profilers.

Use Cases

• Seafloor bathymetry mapping using Kongsberg EM302 multibeam sonar data.
• Analysis of sub-bottom sediment layers via Knudsen 3260 chirp profiler sonar.
• Water column backscatter studies using EK60 split-beam fisheries sonars.
• Marine protected area habitat assessment and baseline characterization.
• Ocean current profiling from Acoustic Doppler Current Profiler (ADCP) measurements.

Strengths

• Data collection targeted specific, ecologically significant marine protected areas (PRIMNM and PIPA).
• Expedition utilized multiple, specialized deep-water mapping systems for concurrent data streams.
• Operations included real-time satellite communications for ship-to-shore data transfer.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last update date, listing both 2017-02-10 and a future date of 2026 04-01.
• License information is not specified.
