Comments P.1 left column: "Ocean water below the sunlit surface layer (i.e., the dark ocean) constitutes 90% of ocean volume and harbors one of the largest microbiomes on Earth (primary source). These microorganisms have a major impact on global carbon cycling, not only through the remineralization of organic material produced by phytoplankton in sunlit surface waters, but also through the chemoautotrophic fixation of inorganic carbon, as reported in several recent studies (refs 2, 3)."
