Fig. 5: Over-compression (ΔP) as a function of compression rate (Π).

Our data points alongside the averaged points from refs. 7,16,17,18 are reported. Temperature at freezing is shown as a color-scale. The gray-dashed lines is the best fit result of the power function ΔP = aΠc + b, with a = 2.6654, b = −2.2544 and c = 0.0564. Inset: Low-pressure phase diagram of H2O showing how the ΔP is calculated for isentropic compressions of refs. 7,17. Errors bars are estimated from the pressure measurements and from the ones given in the literature.
