Discovery transforms understanding of hydrogen depletion at the seafloor

(Lehigh University) Results of a new study by Lehigh University's Jill McDermott and colleagues contradict the assumption that hydrogen depletions at the seafloor are caused by microbiological communities. They found that these shifts in chemistry are driven by non-biological processes that remove energy before microbial communities at the shallow seafloor gain access to it. The results were published online today in the Proceedings of the National Academy of Sciences.
