Hi Bill,

I just mentioned to a postdoc about Madelaine's talk this afternoon and was told that he didn't received any email. I checked your email and found you only informed EOAS faculties about today's talk. I am wondering if this is what you have arranged. Otherwise, more audience may be better, especially in such a big room.

Best,

Zhaohua

Southern Ocean Circulation and Climate: The localizing effect of Topography

Abstract: The Southern Ocean plays a major role in the global air-sea carbon fluxes, with some estimates suggesting it takes up 40\% of the oceanic anthropogenic carbon dioxide. Understanding the Southern Ocean overturning transport is particularly important because the overturning transport fluxes tracers between the depth and the surface.  Recent work shows that this vertical transport preferentially occurs downstream of bottom topography, but there is further work to understand how this relates to the theory of overturning circulation. This study uses an idealized Southern Ocean-like MITgcm channel and particle tracking in the thickness-weighted circulation to develop a new understanding of the three dimensional-nature of the overturning.  This study evaluates the overturning transport by splitting the flow into the main driving forces behind the transport.  The existence of the ridge weakens the response of the overturning to changes in wind, especially in the lower cell.   In addition, air-sea carbon flux is enhanced over the topography.  The localization of the vertical flow shows the necessity of careful modeling of these specific regions in the Southern Ocean to understand the transport and carbon export.

 William Dewar is inviting you to a scheduled Zoom meeting.
