NOAA's 2016 Hohonu Moana expedition collected oceanographic data and multimedia from deep-water areas around the Northwestern Hawaiian Islands. Operations included high-resolution visual surveys and specimen sampling using a 6000-meter ROV, CTD rosette, and ship-based mapping systems. The dataset provides a baseline for exploration and research in the Papahanaumokuakea Marine National Monument region.
Use Cases
- Analyze ROV dive video and imagery to classify deep-sea biological specimens and geological features.
- Correlate CTD rosette sensor data with dive locations to model water column properties in the Northwestern Hawaiian Islands.
- Map seafloor bathymetry and features using data from the ship's deep-water mapping systems.
- Study temporal and spatial patterns of exploration from dive logs and telepresence communication records.
Strengths
- Data collected using a 6000-meter capable ROV system for deep-sea access.
- Includes multiple data modalities: visual surveys, sensor data, and mapping outputs.
- Covers a specific expedition from February to March 2016 with a clear geographic focus.
Limitations
- Specific sample size, row counts, and file formats are unknown.
- Data is from a single, time-bound expedition, limiting longitudinal analysis.
- Potential bias towards daytime ROV dives and explored areas during the cruise.
