<div><p>Carbonate rocks were collected across seepage gradients at Mound 12 using HOV Alvin, and washed in miliQ water onboard. Before preserving, the sample was kept cold and animals were picked to sample tissue for isotope analysis. The tissue (aprox. 0.5 mg) was placed in pre weighted tin boats or combusted vials (500C overnight) and frozen at -70C. The remaining washed sample was sieved through 0.3 mm mesh, separating the sample in two fractions (a fine fraction with the meiofauna, and a coarser one with the macrofauna), both preserved in 96% Ethanol. In the laboratory, tissue samples were oven dried (60C) overnight, weighed and acidified with 12.5-25 ul 1N H3PO4 to remove inorganic C.</p>
