Sampling locations in the SMAR vents.
A: The Golden Valley vent covers approximately 30 m of a long N-S oriented 3–5 m deep fissure at 4°48.16′S, 12°22.28′W. The walls and the bottom of the fissure are densely covered with golden-brown Bathymodiolus sp. which gave rise to the name. B: The Wideawake vent site lies in a jumbled lava sheet flow and is characterized by extensive beds of Bathymodiolus sp. and associated diverse fauna, including occasional Abyssogena southwardae clams. C: Small Bathymodiolus sp. covering pillow lava and semi-lithified Fe-oxyhydroxide crust at the Lilliput vent field at 9°32.83′S, 13°37.74′S. D: Close-up of Lilliput mussels.
