Oceanographic data and ROV dive-related multimedia and information collected during the EX1603 Hohonu Moana: Exploring the Deep Waters off Hawai`i expedition on NOAA Ship OKEANOS EXPLORER in the North Pacific Ocean from 2016-02-23 to 2016-03-16 (NCEI Accession 0150527)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2025-09-30T00:00:00.000+00:00
This dataset contains oceanographic data collected in the waters just outside of Papahānaumokuākea Marine National Monument (PMNM) in the Northwestern Hawaiian Islands, along the transit from Midway to Kwajalein in the Marshall Islands. Operations for this cruise included ROV, mapping, telepresence-based remote participation, and CTD rosette operations. The ship's deep water mapping systems were used, as well as NOAA's two-body 6000 m remotely operated vehicle, CTD rosette, and high-bandwidth satellite connection for real-time ship to shore communications. Daytime ROV dives included high-resolution visual surveys and limited rock and biologic specimen sampling. Exploration operations focused on deep-water areas around the Northwestern Hawaiian Islands, and will help establish a baseline of information in the region to catalyze further exploration, research, and management activities.
