The project will assess the salinity tolerances and ability to acclimatise to lowered salinity in a range of Antarctic marine invertebrates. It will also assess the impacts of multiple stressors (at least elevated temperature and lowered salinity). The aim is to provide a much better set of predictions about what types of species (in relation to taxonomic identities and ecological and functional roles) are more and less resistant to future predicted environmental changes in Antarctic coastal ecosystems. The project will be primarily experimental assessing tolerances of species in the laboratory to both survival limits and sublethal responses. This will involve the use of morphological, physiological and genomic methods to evaluate capacities to respond to the environmental insult. Experiments will primarily be set in the cold-water marine aquarium in the British Antarctic Survey on animals routinely returned to UK from their Rothera station in Antarctica.

该项目将评估一系列南极海洋无脊椎动物的耐盐性和适应低盐度的能力。它还将评估多种压力源（至少是温度升高和盐度降低）的影响。其目的是提供一个更好的预测什么类型的物种（在分类身份和生态和功能的作用）是更多和更少的抵抗未来预测的环境变化在南极沿海生态系统。该项目将主要是实验性的，在实验室评估物种对生存极限和亚致死反应的耐受性。这将涉及使用形态学、生理学和基因组学方法来评估对环境损害作出反应的能力。实验将主要在英国南极调查局的冷水海洋水族馆进行，动物通常从南极洲的罗瑟拉站返回英国。
