Fig. 4From: Geophysical constraints on microbial biomass in subseafloor sediments and coal seams down to 2.5 km off Shimokita Peninsula, JapanEffective pressure dependence of a permeability and b porosity of core samples at Site C0020. The fits estimated by the least squares method and errors are also shown.
