This project aims to greatly improve the cost-effectiveness of actions to protect and restore shallow subtidal marine habitats by quantifying the severity and distribution of recent human impacts. Environmental change will be quantified as the difference between contemporary and historical assemblages encompassing thousands of invertebrate species, and by reading historical chronicles coded by mollusc shells layered in sediments. The roles of different stressors (warming, dredging, eutrophication, introduced species, sediment runoff) will be distinguished. Expected outcomes include continental-scale understanding of factors that facilitate ecosystem decline and recovery, and of sites and species traits most affected by ongoing threats.

该项目旨在通过量化近期人类影响的严重程度和分布情况，大大提高保护和恢复潮下浅海生境行动的成本效益。环境变化将被量化为包括数千种无脊椎动物物种的当代和历史组合之间的差异，并通过阅读沉积物中分层的软体动物贝壳编码的历史编年史。将区分不同压力源（升温、疏浚、富营养化、引进物种、沉积物径流）的作用。预期成果包括在大陆范围内了解促使生态系统衰退和恢复的因素，以及受持续威胁影响最大的地点和物种特征。
