WAMSI 2 - Dredging Node - Project 4.6 - Defining Thresholds and Indicators of Coral Response to Dredging Related Pressures - SEA SIM LAB EXPERIMENTS, Western Australia

Overall objectives of WAMSI DREDGING SCIENCE NODE Project 4.6 were to better understand the effects of dredging pressures on corals by better understanding cause:effect pathways, and identified, determining pressure:response relationships.This report describes a series of 5 experiments conducted at the National Sea Simulator (Sea Sim) based at the Australian Institute of Marine Science (AIMS, Townsville, Queensland) using 8 different coral species. Experiments followed a logical sequence with treatment levels usually based on previous experimental results and were separated into studies associated with suspended sediments and light attenuation (experiments 1, 2, and 3), sediment deposition (experiment 4), and the effects of bleaching (from thermal stress) on sediment clearance capability of corals (Experiment 5).

WAMSI疏浚科学节点项目4.6的总体目标为：通过厘清因果作用路径、明确压力-响应关系，深入解析疏浚压力对珊瑚的影响。本报告详述了在设于澳大利亚昆士兰州汤斯维尔的澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）的国家海洋模拟器（National Sea Simulator, Sea Sim）中开展的5组实验，实验共采用8种不同珊瑚物种。实验遵循严谨的逻辑时序，各处理组水平通常基于前期实验结果设置，整体分为三大研究方向：悬浮沉积物与光衰减相关研究（实验1、2、3）、沉积物沉积相关研究（实验4），以及热胁迫引发的珊瑚白化对其沉积物清除能力的影响研究（实验5）。
