0215670DetrickThis Major Research Instrumentation award to Woods Hole Oceanographic Institution in Massachusetts provides funds to develop and test a prototype deep-water, acoustically-linked, moored-buoy seafloor observatory. The system will consist of a discus buoy on a single-point, deep-water mooring, equipped with a satellite link for 2-way communication to shore and a high-speed acoustic modem for 2-way communication with sensors on the seafloor and on the mooring itself. The suite of sensors, at two seafloor nodes, will include an ocean bottom seismograph (OBS), an acoustic current profiler (ADCP), hydrothermal flow meters with associated temperature, chemical and pressure sensors and a conductivity-temperature-depth (CTD) instrument. All will be interfaced to two acoustic modems, and they will transmit data to the surface buoy of the mooring, from which they will be transmitted daily to shore together with meteorological data from sensors on the surface buoy and current meter data from instruments installed on the mooring. The mooring will be deployed for a 15-month demonstration project in the vicinity of the Nootka Fault, where complementary observatory experiments will be carried out under separate support from the Keck Foundation. The project is supported by the Division of Ocean Sciences at NSF. Cost-share support from non-federal funds will be provided for approximately 30% of total project costs.***

0215670Detrick 这项重大研究仪器奖授予马萨诸塞州伍兹霍尔海洋研究所，提供资金用于开发和测试深水、声学连接、系泊浮标海底观测站原型。 该系统将由单点深水系泊上的铁饼浮标组成，配备用于与岸上双向通信的卫星链路和用于与海​​底和海上传感器进行双向通信的高速声学调制解调器。系泊装置本身。 该套传感器位于两个海底节点，包括海底地震仪（OBS）、声流剖面仪（ADCP）、带有相关温度、化学和压力传感器的热液流量计以及电导率-温度深度（CTD）仪器。 所有这些都将连接到两个声学调制解调器，并将数据传输到系泊装置的表面浮标，这些数据每天都会从表面浮标上与来自表面浮标传感器的气象数据和来自安装在浮标上的仪器的海流计数据一起传输到岸上。停泊。 该系泊装置将用于努特卡断层附近为期 15 个月的示范项目，该项目将在凯克基金会的单独支持下进行补充观测站实验。 该项目得到了美国国家科学基金会海洋科学部的支持。 非联邦基金的成本分摊支持将提供约 30% 的项目总成本。***
