Geochemical modeling of vent environments (funded by National Science Foundation grant OCE-0002634)

Geochemical models can be used to examine the likely thermal and chemical environments that exist (a) beneath the seafloor (where vent fluid and seawater mix (McCollom and Shock, GCA, 1997)), and (b) within chimney walls and flanges (where interactions between seawater and vent fluid are dominated by diffusion with variable advection (Tivey, 2004) ).
