NOAA Okeanos Explorer ROV Dive and Oceanographic Data from Wake Island

NOAA's Okeanos Explorer expedition EX1606 collected oceanographic data and remotely operated vehicle (ROV) dive information in the North Pacific Ocean around Wake Island and along transits from Guam to Kwajalein. The dataset includes high-resolution visual surveys, rock and biologic specimen sampling, CTD casts, and deep-water mapping operations conducted from July 27 to August 19, 2016. This baseline information aims to catalyze further exploration, research, and management activities in the region.

Use Cases

• Analyzing deep-water biodiversity and habitat structure from ROV high-resolution visual surveys.
• Studying oceanographic conditions (e.g., conductivity, temperature, depth) using CTD rosette cast data.
• Mapping seafloor bathymetry and features from overnight mapping transit operations.
• Cataloging limited rock and biological specimen samples collected during ROV dives.
• Investigating real-time telepresence capabilities for ship-to-shore scientific collaboration.

Strengths

• Data collection utilized advanced NOAA equipment including a 6000m capable ROV and deep-water mapping systems.
• Expedition established a baseline for a previously underexplored region (Wake Island Unit PRIMNM).
• Operations combined multiple methods: daytime ROV dives, overnight mapping, and targeted CTD casts.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date: Data.gov lists 2026-04-01, while NASA Earthdata lists 2016-08 19.
• The dataset's license and precise data formats beyond HTML are unknown.
