Active subseafloor microbial communities from Mariana back arc venting

The level of hydrothermal activity on any spreading axis is related to the underlying geology and tectonic setting and while the three back arc segments sampled for this study share the same basaltic host rock their tectonic settings differ the Hafa Adai vent field on the 17°N segment has a more robust magmatic contribution than the northern and southern sites as well as a considerably
