Davies Reef Deployments of the Wireless Sensor Network

Sensor network infrastructure was installed at Davies Reef in the central Great Barrier Reef off Townsville, Australia. The infrastructure consists of a base station mounted on the existing reef communications tower and a number of buoys which carry the actual sensors.The initial design is to monitor the flow of water through the lagoon, the connectivity between the lagoon and the open ocean and the presence of an upwelling signal as oceanic water crosses the open shelf in the Townsville region. This site is linked to ones on the edge of the shelf (Myrmidon Reef) and sites closer in such as Rib Reef and Orpheus Island.The deployment in December 2009 consisted of the base station using the Telstra nextG service and five buoys or sensor floats. The sensor floats carry a mixture of sensors but typically a surface MEA Thermistor and a bottom mounted SeaBird SBE39 (temp + pressure), for some floats the SBE39 is replaced by a SBE37 to give salinity (as conductivity), temperature and presure.On the tower is a vaisala WXT520 weather station.The project looks to deploy sensor networks at seven sites along the Great Barrier Reef to measure a range of physical parameters at a range of scales. The project will install communications, data and platform infrastructure that will support future sensor work looking at biological and chemical parameters.Wireless Sensor Networks Facility (formerly known as Facility for The Automated Intelligent Monitoring of Marine Systems (FAIMMS)), part of the Great Barrier Reef Ocean Observing System project (GBROOS) (IMOS)

澳大利亚汤斯维尔（Townsville）外的大堡礁（Great Barrier Reef）中部戴维斯礁（Davies Reef）部署了传感器网络基础设施。该基础设施由安装在现有礁体通信塔上的基站，以及搭载实际监测传感器的多组浮标构成。初始设计目标为监测潟湖内的水体流动、潟湖与外海的水体连通性，以及汤斯维尔区域外海水体穿越开阔陆架时的上升流信号特征。该站点与陆架边缘的迈尔米登礁（Myrmidon Reef）站点，以及更近的里布礁（Rib Reef）和奥菲斯岛（Orpheus Island）站点实现互联互通。2009年12月的首次部署包含一套采用澳洲电信（Telstra）nextG服务的基站，以及五组浮标或传感器浮筒。传感器浮筒搭载多种传感器，常规配置为表层MEA热敏电阻传感器，与海底安装的西贝德（SeaBird）SBE39型（温度+压力）传感器；部分浮筒将SBE39替换为SBE37型传感器，可同步采集盐度（以电导率表征）、温度与压力数据。通信塔上搭载了维萨拉（Vaisala）WXT520型气象站。本项目计划在大堡礁沿线的7个站点部署传感器网络，以多尺度采集各类物理参数。项目将搭建通信、数据与平台基础设施，为后续开展生物与化学参数相关的传感器监测工作提供支撑。无线传感器网络设施（Wireless Sensor Networks Facility，前身为海洋系统自动化智能监测设施（Facility for the Automated Intelligent Monitoring of Marine Systems, FAIMMS）），是大堡礁海洋观测系统项目（Great Barrier Reef Ocean Observing System, GBROOS）的组成部分，该项目隶属于综合海洋观测系统（IMOS）。
