WAMSI 2 - Dredging Node - Project 4.9 - Defining Thresholds and Indicators of Coral Response to Dredging Related Pressures - Mortality Pathways and Water Quality Thresholds

Data is in the form of a Microsoft Access databases, excel workbooks and csv files, showing the original data together with site information (GPS coordinates), and 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 4.9, is to thoroughly characterise how dredging activities alters 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 these changes in water quality impact on coral health. The data are important for developing water quality thresholds for dredging projects and to improve the ability to predict and manage the impact of future projects.

Data used to conduct these analyses were from four large scale capital Dredging projects conducted in the Pilbara region of Western Australia using in situ water quality instrumentation, as well as time series photographic images of individual coral heads (available for the Gorgon project at Barrow Island only). Federal Ministerial Approval Statements for the four projects: MS757, MS800, MS840, MS0873, which are 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.

数据集以Microsoft Access数据库、Excel工作簿及CSV文件形式存储，包含原始数据、站点信息（GPS坐标）与采集日期。此外还提供了经加密处理的、可打印且不可编辑的可检索便携文档格式（Portable Document Format，PDF）分析结果报告。

西澳大利亚海洋科学机构（Western Australian Marine Science Institution, WAMSI）疏浚科学节点项目4.9的核心目标，是系统表征疏浚活动如何从时空特征（含时间序列光谱分析）维度改变礁体海域水质——包括总悬浮固体（total suspended solids, TSS）浓度、水下光照水平与光合有效辐射（photosynthetically active radiation, PAR，即光衰减），并阐明此类水质变化对珊瑚健康的影响。本数据集可为疏浚项目水质阈值的制定提供支撑，同时提升对未来项目影响的预测与管理能力。

本次分析所用数据，源自西澳大利亚州皮尔巴拉地区的4项大型资本性疏浚项目，数据采集采用原位水质监测仪器，同时包含单颗珊瑚群落的时序影像资料（仅可从巴罗岛高庚（Gorgon）项目获取）。4个项目的联邦部级审批文件编号为MS757、MS800、MS840、MS0873，可在西澳大利亚州环境保护局（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，但需获得对应企业的审批同意。
