Comments P.2 left column 4th paragraph: "Estimates of the total amount of microbial biomass (i.e., cellular organic carbon) in the seabed range from 4 to 300 Pg C (primary sources). However, these estimates were not based on direct measurements of the carbon content of sub-seafloor microbial cells. Instead, they were based on mean cellular carbon contents that were deduced either from mean literature values (primary source Parkes et al., 1994), cell dry weight (primary source Whitman et al., 1998), sedimentary lipid biomarker concentrations (primary source Lipp et al., 2008), or cell volumes (primary source Kallmeyer et al., 2012)." Pg C=10^15 grams carbon
