What are the impacts of tectonic and What are the impacts of tectonic and magmatic perturbations on biogeochemical magmatic perturbations on biogeochemical and hydrological processes in ridge crest and hydrological processes in ridge crest environments and the overlying water environments and the overlying water column?column?
What are the total fluxes of heat, chemistry, What are the total fluxes of heat, chemistry, and biomass out of a hydrothermal system? and biomass out of a hydrothermal system?
Endeavour Node
Instrument Update
High T vent sites:• microbial incubator – in progress, no contract • temperature-hydrogen-resistivity probe – in progress, no contract
• Imaging sonar system –2010?
Low T vent sites:• tempo-mini – camera, temperature probes, O probes; recently tested at VENUS
• fluid sampler – in progress, no contract• camera – ??
Regional circulation moorings:• CTD, ADCP, current metres – almost ready?
