Extraordinarily high biomass benthic community on Southern Ocean seamounts

Thresher, R.E.; Adkins, J; Fallon, Stewart; Gowlett-Holmes, K.; Althaus, F.; Williams , A.


We describe a previously unknown assemblage of seamount-associated megabenthos that has by far the highest peak biomass reported in the deep-sea outside of vent communities. The assemblage was found at depths of 2-2.5 km on rocky geomorphic features off the southeast coast of Australia, in an area near the Sub-Antarctic Zone characterised by high rates of surface productivity and carbon export to the deep-ocean. These conditions, and the taxa in the assemblage, are widely distributed around the...[Show more]
