Chemosynthetic ecosystems in the Gulf of Mexico (GOM) support dense communities of seep megafaunal invertebrates that rely on endosymbiotic bacteria for nutrition. Distinct infaunal communities are associated with the biogenic habitats created by seep biota, where habitat heterogeneity and sediment geochemistry influence local macrofaunal community structure. Here we examine the variance in infaunal communities in the GOM with respect to depth, sediment geochemistry parameters, and distance to known seep habitats. Habitats were mapped based on ROV video of the seafloor. Samples were collected from three sites (AC601, GC852, and AT340) via box core in 2007 and processed for macrofauna and environmental characteristics....
