SUMMARY:The frozen frontiers of our solar system - Dr Nicole Shibley\, DAM

DESCRIPTION:Fluid physics govern many phenomena in the Universe. For examp
 le\, fluid processes in Earth’s polar regions are central to understandi
 ng Earth’s climate system and can also give insight into the climate sys
 tems of other planetary bodies. In this talk\, I will describe how polar r
 esearch on Earth may help us understand ocean properties on icy satellites
  in the Solar System\, where in-situ measurements are not available. We wi
 ll largely focus on Europa\, a moon of Jupiter\, thought to have an ice sh
 ell overlying a global liquid-water ocean. How does this ice shell grow an
 d move? What can the thermodynamics and dynamics governing this growth and
  movement tell us about the evolution of Europa and help us infer about it
 s subsurface ocean? We will discuss how idealized models of Europa’s ice
  shell\, adapted from considerations of Earth’s cryosphere\, can be coup
 led with forthcoming planetary observations to infer physical properties t
 hat cannot be directly measured. Finally\, we will discuss how fluid dynam
 ics can help us explore open questions in geophysical and astrophysical sc
 iences both on Earth and beyond.
