Comments Abstract: "[Investigators] show that terrestrial biomass is about two orders of magnitude higher than marine biomass and estimate a total of ≈6 Gt C of marine biota, doubling the previous estimated quantity." P.3 right column 2nd paragraph: "Examining global biomass in different environments exposes stark differences between terrestrial and marine environments. The ocean covers 71% of the Earth’s surface and occupies a much larger volume than the terrestrial environment, yet land biomass, at ≈470 Gt C, is about two orders of magnitude higher than the ≈6 Gt C in marine biomass, as shown in Fig. 2A."
