During the 2007 MEDECO cruise of RV Pourquoi Pas ? (Sarrazin & Pierre, 2007),, biomass-dominant fauna was sampled in two deep-sea cold seep ecosystems: the Napoli and Amsterdam mud volcanoes (Eastern Mediterranean, depth range: 1939 - 2152 m). Stable isotope ratios of carbon, nitrogen and/or sulfur were measured in 129 samples belonging to 28 taxa, as well as surrounding sediments. Samples were identified, dissected in a cold room and frozen at -20°C on board, then brought back to the laboratory for further processing. Analytical measurements were performed at Iso-Analytical Limited laboratories, Crewe, United Kingdom (
