Role of Chemosynthetic Thermophilic Communities on the Biogeochemical Cycles of Minerals in the Orca Seamount Area, Antarctica
The Orca Seamount is a submarine volcanic structure, located in a tectonic area of the Bransfield Strait, characterized by cortical extension and roll back-type subduction. Recent investigations have described the presence of hydrothermal activity and thermophilic microorganisms in this submarine vo...
