Fig. 5: Methane and sulfate concentrations in pore waters.
From: Gas hydrate dissociation linked to contemporary ocean warming in the southern hemisphere

A transect across the edge of the hydrate stability zone with six piston cores (PC) showing methane and sulfate concentration in pore waters (location in Fig. 1). The depth of the sulfate−methane transition (SMT) is indicated in each profile with a dashed orange line, drawn at the depth of no sulfate.
