Galway Bay Observatory ADCP Data (processed)

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 publicly 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. A Teledyne RDI Workhorse Broadband 600KHz acoustic Doppler current Profiler (ADCP) is mounted on the observatory infrastructure. It is approximately two metres above the seabed, looking up towards the sea surface. Data are collected every minute for 1.0 m depth bins from approx. 1 Metre above the instrument to the surface. Data are collected in RDI’s PD0 binary format (more information is available from the link: http://spiddal.marine.ie/data.html#adcp and structures. The.PD0 raw files are processed as they are collected and the real time values for the Near Surface and Mid Water Current Speeds and Directions are extracted. The extracted values are displayed in near-real-time on smartbay.marine.ie. The processed data is also provided via an ERDDAP data server allowing the data to be downloaded in a range of open formats. Dataset properties include: Serial number, Time (UTC), Bin number, Beam Angle, Correlation values, depth, Direction, Echo Intensity, Magnetic Compass Heading, Instrument Id, Latitude, Longitude, Percent good, Roll, salinity (PSU), Sound Speed, Temperature, Velocity.位于爱尔兰戈尔韦湾的SmartBay观测站（SmartBay Observatory）是一套水下观测系统，通过摄像机、探测仪与传感器（SENSORS）实现连续远程水下监测。该观测站于2015年部署在爱尔兰戈尔韦郡斯皮德尔（Spiddal）沿岸外1.5公里的海床之上，作业水深为20至25米。水下观测站为海洋研究者提供了独特的实时访问渠道，可实时监测海洋环境的动态变化。戈尔韦湾观测站是爱尔兰对日益壮大的全球海洋实时数据采集系统网络的重要贡献。 戈尔韦观测站海域的海洋环境数据通过光纤电信线缆实时传输至爱尔兰海洋研究所总部，随后在互联网上向公众开放。所采集的数据包括实时视频流、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——这些参数可反映水体中浮游植物及沉积物等颗粒物的含量。该观测站每18至24个月需进行一次维护作业。 观测站基础设施上搭载了一台Teledyne RDI Workhorse Broadband 600KHz声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP），其安装位置距海床约2米，探头朝上朝向海面。该仪器以1.0米为深度分层间隔，在距仪器约1米至海面的范围内，每分钟采集一次数据。 数据以RDI的PD0二进制格式存储（详细信息可参阅链接：http://spiddal.marine.ie/data.html#adcp）。采集到的原始.PD0文件会在接收的同时进行处理，提取近表层与中层水流的流速和流向实时值，并在smartbay.marine.ie网站上近乎实时地展示。处理后的数据还可通过ERDDAP数据服务器获取，支持以多种开放格式下载。 数据集属性包括：序列号、时间（UTC）、分层编号、波束角、相关值、水深、流向、回波强度、磁罗盘航向、仪器ID、纬度、经度、有效数据百分比、横滚角、盐度（PSU）、声速、温度、流速。
