[Eoas-seminar] MET Seminar Series, Thursday, Oct. 15, 2020 at 3:30 PM

[eoas-seminar at lists.fsu.edu]

Dear colleagues,

I am here, on behalf of Drs. Wing and Sura and with great pleasure, to announce that we will have a MET seminar series this semester. The first speaker will be Dr. Wanying Kang of MIT and she will give a talk on Thursday, Oct. 15, 2020 at 3:30 PM. Wanying earned her Ph.D later last year at Harvard University and is currently a MIT distinguished university postdoctoral fellow (https://wanyingkang.com/cv/). She has published extensively in different areas in climate dynamics, including Madden-Julian Oscillation (a well-known tropical phenomena) and its interactions with high latitude and high altitude phenomena, climate dynamics of other planets or moons in and out the solar system. The detailed information of her seminar is here (also see the attached flyer):

Title:
What shapes Ice Shell of Enceladus?

Abstract:
Beneath the icy shell encasing Enceladus, a small icy moon of Saturn, a global ocean of liquid water ejects geyser-like sprays into space through fissures concentrated near the south pole, making it one of the places with the highest potential of finding extraterrestrial life. The existence of an ocean has been attributed to the heat generated in dissipative processes associated with the deformation of Enceladus by tidal forcing. However, it remains unclear whether heat is mostly generated in its ice shell or silicate core, and what gives rise to the dramatic asymmetry between the northern and southern hemispheres. Answering these questions is crucial if we are to understand the dynamics behind the active south pole and to unravel patterns of ocean circulation, tracer transport and biosignatures important for the habitability and detectability of potential life. In this presentation, we discuss how we might infer the partition of heat generation between ice shell and core, and demonstrate how the hemispheric asymmetry of ice shell topography could form out of initial random perturbations through mode growth.
