ME34C:
Microbial Biogeochemistry of Hydrothermal Vents in Shallow and Deep Waters: Commonalities and Differences Posters


Session ID#: 9584

Session Description:
Submarine hydrothermal systems in shallow- and deep-water are both the result of volcanic or tectonic activity, hosting habitats that are strongly driven by geophysical and geochemical extremes operating on a wide range of spatial scales. Yet, both systems are often studied in separation. This session intends to bridge this gap and seeks contributions from shallow and deep-sea vent systems, covering geochemistry and microbiology, examining specifically the hydrothermal effects on microbial diversity and function and the impact of microbial activity on fluid composition. The session aims at synthesizing the knowledge from both systems and at building a ‘toolbox’ to use geochemical parameters to predict community composition and functioning in submarine hydrothermal systems, based on observations, experimental work and models. Conversely, the session shall also enhance our understanding of the impact of microbial activity on chemical fluxes of both inorganic and organic constituents within hydrothermal systems and on the surrounding ocean. We also encourage contributions focusing on the potential significance of hydrothermal vents as sites for the origin of life and as potential analogs for life elsewhere in the universe.
