Map of seafloor ecosystems. Datasets with spatially distributed sites are numbered (e.g., NZS1-10). Abbreviations of methane seeps (orange) and subsurface sulfate methane transition zones (SMTZ; purple) stand for ANT, Low-activity Antarctic seep; BS, Black Sea microbial reef; DS, Gulf of Cadiz mud volcanoes; GB, Guaymas Basin hot seeps; GoM, Gulf of Mexico seeps; HMMV, Håkon Mosby mud volcano; HR, Hydrate Ridge seeps; JAP, Japanese Trench seep; KO, Congo Basin (REGAB) seep; NS, North Sea seep; NZ, New Zealand seeps; QS, Quepos Slide seep (Costa Rica); and ST, Storegga Slide seep (Norway). Other abbreviations are as follows. Deep-sea surface sediments (brown): SMS, Station M; NZS, New Zealand. Coastal sediments (green): AGW, Amazon–Guiana Waters; CR, Hawaiian Coral Reef; LCR, Latin American Coastal Regions; MM, North Sea Intertidal Microbial Mat; VAG, Chilean Coast sediment. Subsurface sediments (blue): DS4/ODP, Peru Margin Ocean Drilling Core. Hydrothermal Vents (red): ASV, Azores Shallow Vents; LC, Lost City Vent Field; LV, Lau Vent Field.
