WAMSI 2 - Dredging Node - Project 4.2 - Defining Thresholds and Indicators of Coral Response to Dredging Related Pressures - WATER QUALITY, Western Australia

Data is in the form of a Microsoft Access database, showing the original data together with site information (GPS coordinates), date collected. Data is also in the form of a report, which will be a secured (printable, non-editable), searchable, Portable Document Format (PDF) showing the results of the analyses

The aim of the Western Australian Marine Science Institution (WAMSI) DREDGING SCIENCE NODE Project 4.2, was to thoroughly characterise how dredging activities altered reef water quality (i.e. total suspended solids levels (TSS), underwater light levels and photosynthetically active radiation (PAR) i.e. (light attenuation) in terms of temporal and spatial characteristics (including spectral analyses of temporal patterns) and how the nature of dredging-related turbidity events differed from natural turbidity events in terms of intensity, duration and frequency. The results are valuable for future experiments and the design of more environmentally realistic laboratory-based, ex situ studies of the effects of turbidity and light reduction on reef biota. Together with analyses of the effects of these dredging projects on the underlying reef communities (Western Australian Marine Science Institution (WAMSI) DREDGING SCIENCE NODE Project 4.6) the data is important for developing water quality thresholds for dredging projects and to improve the ability to predict and manage the impact of future projects (see Western Australian Marine Science Institution (WAMSI) DREDGING SCIENCE NODE Project 4.6)

Data used to conduct these analyses was from three large captial Dredging projects conducted in the Pilbara region of Western Australia using in situ water quality instrumentation (Federal Ministerial Approval Statements: MS757, MS800, MS840, which searchable on the WA EPA website: http://www.epa.wa.gov.au). These data are available through a data sharing agreement with WAMSI, pending approval of the individual companies.

数据集采用微软（Microsoft）Access数据库格式存储，包含原始数据、采样点位信息（全球定位系统（GPS）坐标）以及采集日期。同时还提供一份加密（支持打印、不可编辑）且可检索的可移植文档格式（Portable Document Format，PDF）报告，其中展示了各项分析的结果。
西澳大利亚海洋科学机构（Western Australian Marine Science Institution，简称WAMSI）疏浚科学节点第4.2项目的研究目标，是全面表征疏浚活动对珊瑚礁水质的改变情况——涵盖总悬浮固体浓度（TSS）、水下光照水平以及光合有效辐射（PAR，即光衰减）的时空特征（包含时间模式的光谱分析）——同时厘清与疏浚相关的浊度事件在强度、持续时长与发生频率方面，与自然浊度事件的本质差异。
该研究结果可为未来相关实验，以及设计更贴合实际环境的实验室异地（ex situ）浊度与光照减弱对珊瑚礁生物群落影响研究提供重要参考。
结合针对上述疏浚项目对基底珊瑚礁群落影响的分析（西澳大利亚海洋科学机构WAMSI疏浚科学节点第4.6项目），本数据集可为制定疏浚项目水质阈值、提升未来项目影响预测与管理能力提供关键支撑（详见西澳大利亚海洋科学机构WAMSI疏浚科学节点第4.6项目）。
本分析所用数据源自西澳大利亚州皮尔巴拉地区开展的3项大型疏浚项目，采用原位（in situ）水质监测仪器采集；相关联邦部长级批准声明为MS757、MS800、MS840，可在西澳州环境保护局（WA EPA）官网http://www.epa.wa.gov.au检索获取。
本数据集可通过与WAMSI签署的数据共享协议获取，但需先获得相关企业的批准。
