Porewater geochemistry of two shallow-water hydrothermal vents off Dominica Island (Lesser Antilles)

Petra Pop Ristova, Thomas Pichler, Michael W Friedrich & Solveig I Bühring
Shallow-water hydrothermal systems represent extreme environments with unique biogeochemistry and high biological productivity, at which autotrophic microorganisms use both light and chemical energy for the production of biomass. Microbial communities of these ecosystems are metabolically diverse and possess the capacity to transform a large range of chemical compounds. Yet, little is known about their diversity or factors shaping their structure or how they compare to coastal sediments not impacted by hydrothermalism. To this end, we...
