Extent of sulfate reduction over 29 days in sediment slurries from Station 1 (A,B) and Station 2 (C,D), stored at atmospheric pressure (A,C) and at in situ pressure (B,D) under organoclastic conditions, respectively. Incubations were conducted at atmospheric pressure (hollow square, median denoted as light grey horizontal bar) and high pressure (filled square, median denoted as black horizontal bar) and at 4°C, without addition of substrate (none) or amended with methane, acetate or hydrogen.
