Oceanographic data and information collected during the EX1706 Johnston Atoll (ROV/Mapping) expedition on NOAA Ship OKEANOS EXPLORER in the Pacific Ocean from 2017-07-07 to 2017-08-02 (NCEI Accession 0165181)

This dataset contains oceanographic data collected in and around the Johnston Atoll Unit (JAU) of the Pacific Remote Islands Marine National Monument, the U.S. EEZ around Hawaii, and the high seas during transit to and from JAU. Operations included the use of the ship’s Acoustic Doppler Current Profilers (ADCP), Scientific Computer System (SCS) data acquisition system designed for oceanographic and fisheries applications, and the ship’s high-bandwidth satellite connection for continuous real-time ship-to-shore communications. Underway CTD and XBT casts were also conducted, as well as use of OER’s 6000 m two-body ROV Deep Discoverer and Seirios.

本数据集包含采集自太平洋偏远岛屿海洋国家纪念区约翰斯顿环礁单元（Johnston Atoll Unit, JAU）及其周边海域、夏威夷周边美国专属经济区（Exclusive Economic Zone, EEZ），以及往返JAU途中公海区域的海洋学数据。本次作业使用了科考船搭载的声学多普勒流速剖面仪（Acoustic Doppler Current Profilers, ADCP）、专为海洋学与渔业应用设计的科学计算机系统（Scientific Computer System, SCS）数据采集系统，以及用于实现船岸连续实时通信的船载高带宽卫星链路。此外还开展了走航式温盐深剖面仪（Conductivity-Temperature-Depth, CTD）与抛投式温盐深剖面仪（Expendable Bathythermograph, XBT）的投放作业，并使用了OER旗下的6000米级双体遥控无人潜水器（Remotely Operated Vehicle, ROV）“深海发现者”号（Deep Discoverer）与“塞里奥斯”号（Seirios）。
