Many Australian ports have contaminated sediments that are a legacy of industrial pollution. The resuspension of these sediments through shipping or dredging activity represents an obvious, yet unsubstantiated, threat to the biodiversity and health of marine communities living well above the seafloor. This research proposal addresses a strategic knowledge gap with implications for appropriate management of port operations. Identifying the conditions under which contaminated sediments may cause an impact, and the environmental factors that modify these effects, will produce significant advances in scientific understanding and the results will be of strategic interest to all Australian Port Authorities.

澳大利亚的许多港口都污染了工业污染遗留下来的沉积物。通过航运或疏浚活动使这些沉积物重新悬浮，对生活在海底以上的海洋生物的生物多样性和健康构成明显但未经证实的威胁。这项研究建议解决了战略知识差距，并对港口作业的适当管理产生了影响。确定污染沉积物可能造成影响的条件，以及改变这些影响的环境因素，将在科学理解方面取得重大进展，其结果将对澳大利亚所有港口当局具有战略意义。
