Abstract: [1] Ice I exhibits a complex rheology at temperature and pressure conditions appropriate for the interiors of the ice I shells of Europa, Ganymede, and Callisto. We use numerical methods and existing parameterizations of the critical Rayleigh number to determine the conditions required to trigger convection in an ice I shell with each of the stress-, temperature-and grain size-dependent rheologies measured in laboratory experiments by Goldsby and Kohlstedt (2001). The critical Rayleigh number depends on the i…
