Water Models Show Dissolved Deep Carbon (image) University of California - Davis Share Print E-Mail Caption New computer modeling of water under extreme pressure shows that carbonate could dissolve in water deep in the Earth and so return to the surface. This rendering shows water molecules (white/pink) surrounding a carbonate ion (red/grey) with a section of the Earth in the background.
