Beschreibung:
Plate collision cuases expulsion of fluids and gases and material turnover in the deep ocean along the global subduction zones. Such cold vents are characterized by mineral precipitates and characteristic assemblages of macro organisms. The latter harbor symbiotic bacteria which utilize the chemically-reduced constituents (CH4 and H2S) of the expelled fluids as their energy and supply their host with food. The interaction between tectonically-induced fluid flow and pumping activity of the vent fauna sets up a shallow recirculation system whose magnitude can be estimated from direct measurements by an in situ vent sampling device (VESP) in connection with tracer studies. The dewatering rates based on the biogeochemical estimates agree surprisingly well with those derived from geophysical estimates.
