Water Quality monitoring of Cleveland Bay for the Port of Townsville Limited

Five sites within Cleveland Bay were instrumented with Wetlabs NTU (turbidity), LiCor PAR (light as PAR) and Diver CTD instruments with monthly data download and collection of water samples for TSS analysis. Instruments were deployed in September 2014 and removed in August 2017 under a contract with the Port of Townsville Limited (PoTL).The work was to understand background and dredging turbidity within the bay. Sites were located in the eastern part of the Bay (JCU Seagrass Watch site 'Meadow-19' = Site CB), at Florence (Site FB), Geoffrey (Site GB) and Picnic Bays (Site PB) around magnetic Island and at Virago Shoals (Site VS) off Pallarenda.Data from the Cleveland Bay AIMS weather station were also provided along with MMP data for Picnic Bay.
To monitor background levels of turbidity (as NTU and underwater light) in the Bay and to provide information on potential impacts of maintenance dredging on turbidity levels at sensitive receptor sites (Coral Reefs - Florence, Geoffrey and Picnic Bays, Seagrass - Virago Shoals and Meadow-19).
Data was collected from September 2014 through to August 2017,

克利夫兰湾（Cleveland Bay）内的5个监测点位布设了Wetlabs型NTU浊度仪、LiCor型PAR光合有效辐射仪以及Diver型CTD温盐深仪，每月开展数据下载工作，并采集水样用于总悬浮固体（Total Suspended Solids, TSS）分析。本监测的仪器布设工作于2014年9月启动，2017年8月完成回收，相关工作由汤斯维尔港有限公司（Port of Townsville Limited, PoTL）委托开展。本次研究旨在厘清克利夫兰湾内的背景浊度与疏浚作业引发的浊度特征。监测点位分布于海湾东部区域：包括詹姆斯库克大学（James Cook University, JCU）海草监测点位“Meadow-19”（对应CB点位）、环绕磁岛的佛罗伦斯湾（FB点位）、杰弗里湾（GB点位）与野餐湾（PB点位），以及帕伦达附近的维拉戈浅滩（VS点位）。本次数据集还包含克利夫兰湾澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）气象站的观测数据，以及野餐湾的MMP监测数据。本次监测的核心目标为：掌握克利夫兰湾内的背景浊度（以NTU值与水下光照强度表征）水平，并评估航道维护疏浚作业对敏感受体点位浊度水平的潜在影响——敏感受体点位包括珊瑚礁生境对应的佛罗伦斯湾、杰弗里湾与野餐湾，以及海草生境对应的维拉戈浅滩与“Meadow-19”点位。本次数据采集周期为2014年9月至2017年8月。
