Oceanographic data and ROV dive-related multimedia and information collected during the EX1605L1 (CAPSTONE CNMI & Mariana Trench MNM (ROV & Mapping)) expedition on NOAA Ship OKEANOS EXPLORER in the North Pacific Ocean from 2016-04-20 to 2016-05-11 (NCEI Accession 0155916)

This dataset contains oceanographic data collected in the waters around Santa Rita, Guam and Saipan. Operations used the ship’s deep water mapping systems, NOAA’s two-body 6000 m remotely operated vehicle, and the ship’s high-bandwidth satellite connection for real-time ship to shore communications. Daytime ROV dives were conducted and included high-resolution visual surveys and limited rock and biologic specimen sampling, as well as CTD casts to collect more environmental information at sites of interest. Exploration operations focused on deep-water areas around the Commonwealth of the Northern Marianas Islands (CNMI) and the Marianas Trench Marine National Monument (MTMNM). This expedition helped establish a baseline of information in the region to catalyze further exploration, research, and management activities.

本数据集收录了关岛圣丽塔（Santa Rita）周边海域与塞班岛（Saipan）周边海域采集的海洋学数据。本次科考作业采用了科考母船的深水测绘系统、美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）的双体式6000米级遥控无人潜水器（Remotely Operated Vehicle, ROV），并依托母船的高带宽卫星通信链路实现船岸实时通信。作业期间，科考团队开展了日间ROV潜水任务，涵盖高分辨率视觉勘测、有限范围的岩石与生物标本采样，以及在目标站位投放温盐深仪（Conductivity, Temperature, Depth, CTD）以采集更多环境数据。本次勘探活动聚焦北马里亚纳群岛联邦（Commonwealth of the Northern Mariana Islands, CNMI）及马里亚纳海沟海洋国家保护区（Marianas Trench Marine National Monument, MTMNM）周边的深水海域。本航次为该区域建立了基础信息基线，以推动后续勘探、研究与管理活动的开展。
