Oceanographic data and information collected during the EX1702 American Samoa Expedition: Suesuega o le Moana o Amerika Samoa (ROV/Mapping) on NOAA Ship OKEANOS EXPLORER in the South Pacific Ocean from 2017-02-16 to 2017-03-02 (NCEI Accession 0162490)

This dataset contains oceanographic data collected in Pago Pago, American Samoa. Operations focused within several marine protected areas and included the use of the ship’s deep water mapping systems (Kongsberg EM302 multibeam sonar, EX60 split-beam fisheries sonars, Knudsen 3260 chirp sub-bottom profiler sonar, and Teledyne Acoustic doppler Current Profilers), XBT and Underway CTD casts in support of multibeam sonar mapping operations, OER’s 6000 m two-body ROV Deep Discover and Seirios, and the ship’s high-bandwidth satellite connection for continuous real-time ship-to-shore communications. Operating areas included the Rose Atoll Marine National Monument, National Marine Sanctuary of American Samoa, offshore (not within) of the National Park of American Samoa, and the waters of both American Samoa and Samoa.

本数据集收录了美属萨摩亚帕果帕果（Pago Pago）海域采集的海洋学数据。本次作业聚焦于多个海洋保护区内海域，使用了船舶配套的深水测绘系统，包括康士伯（Kongsberg）EM302多波束声呐（multibeam sonar）、EX60分离波束渔业声呐（split-beam fisheries sonars）、Knudsen 3260啁啾亚底质剖面声呐（chirp sub-bottom profiler sonar）以及泰莱达因（Teledyne）声学多普勒海流剖面仪（Acoustic doppler Current Profilers）；同时开展了抛弃式温深仪（XBT）与走航式温盐深仪（Underway CTD）投放作业，以辅助多波束声呐测绘工作；此外还启用了OER旗下6000米级双体遥控水下机器人（ROV）“深海发现者”（Deep Discover）与“塞里俄斯”（Seirios），并通过船舶的高带宽卫星链路实现船岸间持续实时通信。作业覆盖区域包括罗斯环礁海洋国家纪念碑、美属萨摩亚国家海洋保护区、美属萨摩亚国家公园周边（园区外）海域，以及美属萨摩亚与萨摩亚两国所辖海域。
