SmartBay Observatory Fluorometer data

The SmartBay Observatory in Galway Bay is an underwater observatory which uses
cameras, probes and sensors to permit continuous and remote live underwater monitoring. It was installed in 2015
on the seafloor 1.5km off the coast of Spiddal, Co. Galway, Ireland at a depth of 20-25m. 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. A WetLabs
ECO-FLNTU is installed on the observatory infrastructure. It measures the fluorescence of the seawater to give
an estimate of the volume of chlorophyll present (indicative of the amount of phytoplankton in the seawater) and
it measures turbidity, or the 'cloudiness' of the seawater, caused by the presence of particles such as sediment
from the seabed suspended in the water. The sensor is deployed on the EMSO Smartbay Cable End Equipment Node in
Galway Bay in approx. 25m depth of water.
acknowledgement=The SmartBay Observatory was funded in part by a grant from Science
Foundation Ireland under Grant Number 12/RI/2331. Ongoing operation of the observatory is funded by the Marine
Institute and Sustainable Energy Authority of Ireland.

位于爱尔兰戈尔韦湾的SmartBay观测站是一处水下观测站，它通过使用摄像头、探测器和传感器，实现了对水下环境的持续远程实时监控。该观测站于2015年安装在爱尔兰戈尔韦郡斯比达尔海岸线1.5公里外的海底，深度约为20-25米。水下观测站使得海洋研究人员能够实时监测海洋环境的持续变化。戈尔韦湾观测站是爱尔兰对全球日益增长的实时数据采集系统网络的重要贡献。位于戈尔韦观测站海域的海洋环境相关数据通过光纤通信电缆实时传输至海洋研究所总部，并在互联网上公开。数据包括实时视频流、观测站节点的深度、水温及盐度，以及对水中叶绿素和浑浊度水平的估算，这些数据能够反映出浮游植物及其他颗粒物（如沉积物）在水中的体积。观测站的维护工作每18至24个月进行一次。观测站基础设施上安装了一台WetLabs ECO-FLNTU，该设备测量海水中的荧光强度，以估算叶绿素的体积（指示海水中的浮游植物含量），并测量由海底沉积物等颗粒物悬浮于水中引起的浑浊度，即海水的不透明度。该传感器部署在戈尔韦湾EMSO Smartbay电缆末端设备节点，位于约25米深的水下。
