We summarize the existing experimental data for the self-diffusivity of supercooled liquid water and review two proposals for the temperature dependence of these data. These data are compared to the recently published measurements of the self-diffusivity of amorphous solid water. We discuss the implications of these data regarding the continuity between ASW and supercooled liquid data. The advantages and limitations of using nanoscale thin films to measure the physical properties of metastable amorphous materials are discussed.
