Oceanographic data and information collected during the EX1708 Musicians Seamounts (ROV & Mapping) expedition on NOAA Ship OKEANOS EXPLORER in the Pacific Ocean from 2017-09-06 to 2017-09-30 (NCEI Accession 0170178)

This dataset contains oceanographic data collected in and around Hawaii, the US EEE, and in the High Seas around the Musicians Seamounts. Operations for this cruise were conducted 24 hours/day and consisted of daily remotely operated vehicle (ROV), overnight mapping, and full shore-based participation via telepresence. Operations included the use of the ship’s deep-water mapping system, XBT and CTD casts in support of multibeam sonar mapping operations, OER’s two-body ROV Deep Discoverer and Seirios, and the ship’s high-bandwidth satellite connection for continuous real-time ship-to-shore communications. Data acquisition from shipboard sensors includes navigation data, meteorological data (wind, air temperature, relative humidity, barometric pressure), and oceanographic data (thermosalinograph, sound velocity probe, bathythermograph). Operations also included the use of the ship’s Acoustic Doppler Current Profilers (ADCP).

本数据集收录了采集自夏威夷及其周边海域、美国EEE海域以及音乐家海山周边公海的海洋学数据。本次科考航次采用24小时全天候作业模式，作业内容涵盖每日遥控水下机器人（Remotely Operated Vehicle，ROV）作业、夜间测绘作业，以及通过远程临场通信技术实现全岸基人员全程参与。作业期间使用了本船深水测绘系统、抛弃式温深仪（Expendable Bathythermograph，XBT）与温盐深剖面仪（Conductivity Temperature Depth，CTD）剖面测量作业，以支撑多波束声纳测绘工作；同时部署了海洋探索与研究局（OER）的双体遥控水下机器人作业系统，包含"深发现者"号（Deep Discoverer）与"塞里奥斯"号（Seirios），并依托本船高带宽卫星链路实现船岸间连续实时通信。船载传感器的数据采集内容涵盖导航数据、气象数据（风速、气温、相对湿度、大气压强）以及海洋学数据（温盐仪、声速探头、温深仪）。本次作业还使用了本船的声学多普勒流速剖面仪（Acoustic Doppler Current Profilers，ADCP）。
