Recorded 27 January 2025. Krista Soderlund of the University of Texas at Austin presents "Rotating Convection in Ocean Worlds of the Outer Solar System" at IPAM's Rotating Turbulence: Interplay and Separability of Bulk and Boundary Dynamics Workshop. Abstract: The outer solar system hosts a diverse array of satellites, many of which likely harbor global subsurface oceans beneath their icy shells. We employ theoretical arguments and numerical simulations of rotating convection to investigate ocean currents and heat transfer in these environments. Our findings reveal that strong ocean currents on Enceladus, Titan, Europa, and Ganymede redistribute heat unevenly, driving latitude-dependent variations that could reshape the overlying ice shell. Our initial models assumed spatially uniform boundary conditions, but current work incorporates more realistic processes. For example, tidal dissipation in the rocky mantle creates heterogeneous heating patterns that propagate through the ocean to influence ice shell structure. Spatial variations in ice shell thickness along with melting and freezing may similarly drive horizontal convection in the ocean. Ocean currents may also erode and redistribute mantle materials, modifying seafloor topography over geologic timescales. The recently launched Europa Clipper and JUICE missions will provide critical data on ocean worlds in the Jovian system. Developing predictive models for ocean dynamics and their impacts on the ice shell and seafloor is essential for interpreting these observations and assessing the habitability of these icy satellites.
