Galway Bay Observatory DeploymentJuly2018-xxxx

This is the third deployment of the Galway Bay Observatory having been deployed using the Granuaile vessel in July 2018. Prior to this deployment the Observatory was modified with new Cabling drums and an extended frame. The SmartBay Observatory in Galway Bay is an underwater observatory which uses cameras, probes and SENSORS to permit continuous and remote underwater monitoring. It was installed in 2015 on the seafloor 1.5 km off the coast of Spiddal, Co. Galway, Ireland at a depth of 20-25 m. Underwater observatories allow ocean researchers unique real-time access to monitor ongoing changes in the marine environment. The Galway Bay Observatory is an important contribution by Ireland to the growing global network of real-time data capture systems deployed in the ocean. Data relating to the marine environment at the Galway Observatory site is transferred in real-time through a fibre optic Telecommunications cable to the Marine Institute headquarters and then made publically available on the internet. The data includes a live video stream, the depth of the observatory node, the water temperature and salinity, and estimates of the chlorophyll and turbidity levels in the water which give an indication of the volume of phytoplankton and other particles, such as sediment, in the water. Maintenance take place on the observatory every 18 to 24 months. The Observatory is equipped with a suite of SENSORS, these include: Acoustic Doppler Current Profiler (ADCP) — Teledyne RDI Workhorse Conductivity-Temperature-depth (CTD) sensor probe — Idronaut Ocean-Seven 304 plus Acoustic data that has been collected from the Galway Observatory site using an icListen HF Smart hydrophone Video data is streamed in near-real-time from the observatory and also available for download. A WetLabs ECO-FLNTU is installed on the observatory infrastructure.本装置为高威湾观测站的第三次部署任务，于2018年7月通过格拉纳韦尔号（Granuaile）科考船完成布设。在本次部署前，观测站已完成改装，加装了新型电缆卷筒并加长了机架结构。 高威湾智能观测站（SmartBay Observatory）是一款水下观测平台，搭载摄像头、探测仪与传感器，可实现持续远程水下监测。该观测站于2015年安装于爱尔兰高威郡斯皮德尔（Spiddal）海岸外1.5公里的海床，作业水深为20至25米。水下观测站为海洋研究人员提供了独一无二的实时访问渠道，可监测海洋环境的持续变化。高威湾观测站是爱尔兰对日益壮大的全球海洋实时数据采集网络的重要贡献。 高威观测站海域的海洋环境数据通过光纤通信电缆实时传输至爱尔兰海洋研究所总部，随后公开发布至互联网。数据内容包含实时视频流、观测站节点水深、海水温度与盐度，以及叶绿素和浊度估算值——该指标可反映水体中浮游植物及沉积物等颗粒物的总量。该观测站每18至24个月需开展一次维护作业。 该观测站搭载了一套完整的传感器系统，具体包括： - 声学多普勒流速剖面仪（Acoustic Doppler Current Profiler, ADCP）——Teledyne RDI Workhorse 型号 - 温盐深（Conductivity-Temperature-depth, CTD）探测仪——Idronaut Ocean-Seven 304 plus 型号 - 采用icListen HF 智能水听器采集高威观测站海域的声学数据 - 观测站的视频数据以近乎实时的方式进行流式传输，同时支持下载获取 - 观测站基础设施上安装了WetLabs ECO-FLNTU设备。
