Macrofaunal ecology of sedimented hydrothermal vents in the Bransfield Strait, Antarctica
Sediment-hosted hydrothermal vents, where hot, mineral-rich water flows through sediment, are poorly understood globally, both in their distribution and the ecology of individual vent fields. We explored macrofaunal community ecology at a sediment-hosted hydrothermal vent in the Southern Ocean. This...

Sediment-hosted hydrothermal vents, where hot, mineral-rich water flows through sediment, are poorly understood globally, both in their distribution and the ecology of individual vent fields. We explored macrofaunal community ecology at a sediment-hosted hydrothermal vent in the Southern Ocean. This is the first such study of these ecosystems outside of the Pacific and the furthest south (62˚S) of any vent system studied. Sedimentary fauna were sampled at four sites in the Bransfield Strait (Southern Ocean), with the aim of contrasting community structure between vent and non-vent sites. Geochemical data were used to create and test a novel proxy index to quantify the degree of hydrothermal influence and its influence on deep-sea biota. Macrofaunal communities were clearly distinct between vent and non-vent sites, and diversity, richness and density declined towards maximum hydrothermal activity. This variation is in contrast to observations from similar systems in the Pacific and demonstrates the influence of factors other than chemosynthetic primary productivity in structuring infauna at deep-sea vent communities.
