SUMMARY:Fluid Physics of Ice-Covered Oceans - Nicole Shibley\, University 
 of Cambridge
DTSTART:20250128T120000Z

CONTACT:Dr Rachael Rhodes
DESCRIPTION:Fluid processes in Earth’s polar regions can influence polar
  and global climate and may also allow for a better understanding of the p
 hysics governing climate systems of certain ice-covered planetary bodies. 
 In this talk\, I will describe how a particular Arctic Ocean mixing and he
 at transport process\, diffusive convection\, helps contextualize the warm
 ing Arctic through a synthesis of observational and theoretical approaches
 . In particular\, we will discuss how different ocean mixing mechanisms im
 pact distinct regions of the Arctic and how intermittent turbulence in a c
 hanging Arctic can disrupt the diffusive-convective process. I will also d
 escribe the development of a novel methodology for inferring ocean mixing 
 metrics from oceanographic acoustic measurements\, which helps elucidate h
 ow intermittent turbulence may interact with diffusive-convective structur
 es. Finally\, we will consider how models of Earth’s polar processes\, a
 dapted to understand ice-covered moons in the Solar System\, can provide i
 nsight into planetary bodies where in-situ measurements are not available.
  Emphasis will be placed on how fluid dynamics can address current and fut
 ure climate and environmental challenges both on Earth and elsewhere in th
 e Solar System.
