Three-dimensional models of hydrothermal circulation through a seamount network on fast-spreading crust

- A large region of 18-24 M.y. old seafloor is cooled by fluid flow through seamounts.
- Simulations indicate very high crustal permeability, 10−10 to 10−9 m2.
- Outcrop-to-outcrop circulation at the field site is likely to be 1000-7000 kg/s.
- Outcrop-to-outcrop circulation is less important than single-outcrop circulation.
