  abstract = {{T}his study aims to evaluate the potential for impacts of ocean acidification on {N}orth {A}tlantic deep-sea ecosystems in response to {IPCC} {AR}5 {R}epresentative {C}oncentration {P}athways ({RCP}s). {D}eep-sea biota is likely highly vulnerable to changes in seawater chemistry and sensitive to moderate excursions in p{H}. {H}ere we show, from seven fully coupled {E}arth system models, that for three out of four {RCP}s over 17% of the seafloor area below 500m depth in the {N}orth {A}tlantic sector will experience p{H} reductions exceeding -0.2 units by 2100. {I}ncreased stratification in response to climate change partially alleviates the impact of ocean acidification on deep benthic environments. {W}e report on major p{H} reductions over the deep {N}orth {A}tlantic seafloor (depth >500 m) and at important deep-sea features, such as seamounts and canyons. {B}y 2100, and under the high {CO}2 scenario {RCP}8.5, p{H} reductions exceeding -0.2 (-0.3) units are projected in close to 23% (similar to 15 %) of {N}orth {A}tlantic deep-sea canyons and similar to 8% (3 %) of seamounts - including seamounts proposed as sites of marine protected areas. {T}he spatial pattern of impacts reflects the depth of the p{H} perturbation and does not scale linearly with atmospheric {CO}2 concentration. {I}mpacts may cause negative changes of the same magnitude or exceeding the current target of 10% of preservation of marine biomes set by the convention on biological diversity, implying that ocean acidification may offset benefits from conservation/management strategies relying on the regulation of resource exploitation.},
