Climate-driven impacts further limit the resilience of deep-sea ecosystems to impacts from human activities  . However, assessing cumulative climatic and non-climatic impacts is challenging for these data-poor environments , where lack of knowledge increases the possibility of overlooking ecosystem vulnerabilities and risks . A paucity of information about the natural variability and historical trends of these habitats prevents robust assessment of adaptive capacities and potential vulnerabilities to extreme events . The spatial resolution of CMIP5 models is too coarse to robustly project changes in mesoscale circulation at the seafloor , on which deep-sea ecosystems depend for organic material supplies and dispersal of planktonic and planktotrophic larvae  . Higher-resolution modelling from CMIP6 , multi-annual and high-frequency records of ocean bottom-water properties , and better understanding and accounting of biogeochemical mechanisms of organic carbon transport to the ocean interior is expected to improve this capacity .
