Development and Testing of a Deep-Water, Acoustically-Linked, Moored-Buoy Seafloor Observatory

这项主要研究仪器奖授予了马萨诸塞州伍兹霍尔海洋研究所，为开发和测试一个原型深水、声学连接、系泊浮标海底观测站提供资金。该系统将由单点深水系泊上的一个铁饼浮标组成，配备有与岸上双向通信的卫星链路，以及与海底和系泊本身的传感器进行双向通信的高速声学调制解调器。在两个海底节点上的传感器套件将包括海底地震仪（OBS）、声波电流剖面仪（ADCP）、热液流量计（带有相关的温度、化学和压力传感器）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，它们将数据传输到系泊的水面浮标，每天将数据与水面浮标上传感器的气象数据和系泊上安装的仪器的流量表数据一起传输到岸上。该系泊将在努特卡断裂带附近部署一个为期15个月的示范项目，在那里将在凯克基金会的单独支持下进行补充观测实验。该项目得到了美国国家科学基金会海洋科学部的支持。来自非联邦基金的成本分担支持将提供约30%的项目总成本。***

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.***
