Scope
|
Seafloor is the largest boundary layer of the solid earth system. Huge flux of heat and chemicals has been observed across the layer from the interior of the earth. This flux depends on the subseafloor water advection (named TAIGA). This session focuses on interactions between lithosphere, hydrosphere, and biosphere through the fluid circulation system beneath the seafloor and terrestrial ground and deep earth.
