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)

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.

本数据集收录了在西北夏威夷群岛外太平洋国家海洋保护区（Papahānaumokuākea Marine National Monument，简称PMNM）水域所采集的海洋学数据，数据采集地点位于马绍尔群岛中途岛至夸贾林岛之间的航线。本次航次的作业内容包括遥控潜水器（ROV）作业、测绘、基于远程呈现的远程参与以及CTD浮标操作。船上深海测绘系统得到应用，同时使用了美国国家海洋和大气管理局（NOAA）的双体6000米遥控潜水器、CTD浮标以及宽带卫星连接，以实现实时船岸通讯。白天进行的ROV潜水作业包括高分辨率视觉调查以及有限的岩石和生物样本采集。探险活动集中于西北夏威夷群岛的深海区域，并将有助于建立该区域的信息基准，从而催化进一步的探险、研究和管理工作。
