And under pressure ice melts rather than solidifying further like other substances.

Operation Deepfreeze 1962-63 found the Arneb stranded on Christmas Day in 8'thick pressure ice well short of McMurdo Base.

Scientists believe liquid water is present in the Saturnian moons of Ganymede as a layer sandwiched between high pressure ice and rock.

An attempt to reconnoiter it by helicopter and to land a party of the NZGSAE on it had to be abandoned when the " USS Glacier " was damaged in pressure ice in December 1958.

The cubic oxygen sub-lattices that form the backbone of the ice VII structure persist to pressures of at least 128 GPa; this pressure is substantially higher than that at which water loses its molecular character entirely, forming ice X . In high pressure ices, protonic diffusion ( movement of protons around the oxygen lattice ) dominates molecular diffusion, an effect which has been measured directly.
