  abstract = {{T}he {B}ay of {P}rony, {S}outh of {N}ew {C}aledonia, represents a unique serpentinite-hosted hydrothermal field due to its coastal situation. {I}t harbors both submarine and intertidal active sites, discharging hydrogen-and methane-rich alkaline fluids of low salinity and mild temperature through porous carbonate edifices. {I}n this study, we have extensively investigated the bacterial and archaeal communities inhabiting the hydrothermal chimneys from one intertidal and three submarine sites by 16{S} r{RNA} gene amplicon sequencing. {W}e show that the bacterial community of the intertidal site is clearly distinct from that of the submarine sites with species distribution patterns driven by only a few abundant populations, affiliated to the {C}hloroflexi and {P}roteobacteria phyla. {I}n contrast, the distribution of archaeal taxa seems less sitedependent, as exemplified by the co-occurrence, in both submarine and intertidal sites, of two dominant phylotypes of {M}ethanosarcinales previously thought to be restricted to serpentinizing systems, either marine ({L}ost {C}ity {H}ydrothermal {F}ield) or terrestrial ({T}he {C}edars ultrabasic springs). {O}ver 70% of the phylotypes were rare and included, among others, all those affiliated to candidate divisions. {W}e finally compared the distribution of bacterial and archaeal phylotypes of {P}rony {H}ydrothermal {F}ield with those of five previously studied serpentinizing systems of geographically distant sites. {A}lthough sensu stricto no core microbial community was identified, a few uncultivated lineages, notably within the archaeal order {M}ethanosarcinales and the bacterial class {D}ehalococcoidia (the candidate division {MSBL}5) were exclusively found in a few serpentinizing systems while other operational taxonomic units belonging to the orders {C}lostridiales, {T}hermoanaerobacterales, or the genus {H}ydrogenophaga, were abundantly distributed in several sites. {T}hese lineages may represent taxonomic signatures of serpentinizing ecosystems. {T}hese findings extend our current knowledge of the microbial diversity inhabiting serpentinizing systems and their biogeography.},
