(A) The “Arches” area south of the Tubeworm Pillar location~one year after the 2005/2006 eruption(s), with diffuse vent flow, white staining, brachyuran crabs and Tevnia jerichonana tubeworm colonization at the base of eruptive lava remnants (2503 m depth). (B) Tevnia colonization following the 2005/6 eruption(s) in the TICA vent area with the outstretched Alvin manipulators imaging and collected in-situ fluid chemical data associated with this assemblage (2517 m depth). (C) Living mussels rafted more than 150 m south from the Choo Choo vent site by a lobe of 2005-2006 lava (2507 m depth). No vent site was known in this area prior to the 2005-2006 eruption. Byssus attachment sites (white threads on the mussel shells) indicate not only the frequency of previously attached mussels but also the relative age of these mussels as these remnants of attachments accumulate over time. Distance across the bottom of each image is approximately 2.2 m, 1.3 m, and 0.5 m, respectively. Copyright Woods Hole Oceanographic Insitution.
