Monitoring the Endeavour – Middle Valley Hydrothermal Systems: Integrated heat and mass fluxes and the response of biogeochemical and physical processes to perturbations Kathryn Gillis, Neil Banerjee, David Butterfield, Laurence Coogan, John Delaney, Mark Hannington, Deborah Kelley, Marv Lilley, Russ McDuff, Steven Mihaly, Karlis Muehlenbachs, Adam Schultz, Rick Thomson

What are the impacts of tectonic and magmatic perturbations on biogeochemical and hydrological processes in ridge crest environments and the overlying water column? What are the total fluxes of heat, chemistry, 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?
