This project aims to develop an international database of underwater observations to predict the distribution of seafloor biodiversity over the entire Antarctic continental shelf for the present day and to 2100. Antarctic seafloor communities are unique and highly diverse, but their distribution is poorly known because biological data are sparse. These predictions depend on a unique and validated approach to estimate the present and future redistribution of surface primary production to the seafloor, and will enable calculating the amount of atmospheric carbon captured and stored at the seafloor. The maps will be at an unprecedented resolution of around 2 kilometres, and be invaluable tools underpinning policy, management and future science.

该项目旨在开发一个国际水下观测数据库，以预测当今和到2100年整个南极大陆架上海底生物多样性的分布情况。南极海底群落独特且高度多样化，但由于生物数据稀少，其分布情况鲜为人知。这些预测有赖于一种独特和经过验证的方法来估计目前和未来地表初级生产向海底的重新分配，并将能够计算在海底捕获和储存的大气碳的数量。这些地图的分辨率将达到史无前例的2公里左右，是支撑政策、管理和未来科学的宝贵工具。
