SciTechDaily: Hydrothermal fluid from Picard Vents leads to discovery that transforms understanding of hydrogen depletion at the seafloor

Using samples collected by ROV Jason II and Nereus, Scientists analyzing hydrothermal fluid from Piccard vents at Mid-Cayman Rise found “non-biological processes deplete hydrogen that was thought to be readily available to subseafloor microbial communities; discovery could impact global hydrogen budget.” Read the article here.
