ABSTRACT Between October 2005 and March 2006, a seafloor volcanic eruption occurred at 9[degrees]50'N East Pacific Rise (EPR), establishing a "time zero" for characterizing newly-formed hydrothermal vent habitats and comparing them to pre-emption habitats. Before the eruption, mussels (Bathymodiolus thermophilus) formed large aggregates between 9[degrees]49.6' and 9[degrees]50.3'N. After the eruption, the few mussels remaining were in sparsely-distributed individuals and clumps, seemingly transported via lava flows or from mass wasting of the walls of the axial trough. In situ voltammetry with solid state gold-amalgam microelectrodes was used to characterize the chemistry ...
