ACEAS has established a monthly seminar series. The seminars will be held once a month and announced on this page.

The ACEAS Seminar Series organising committee is Sandeep Mohapatra (UTAS), William Scott (ANU) and Fabio Dias (UNSW). If you are interested in presenting, or would like to nominate a speaker, please email us: ACEAS.Project.Office@utas.edu.au

Abstract: The uptake and vertical redistribution of heat and carbon is a crucial component of the ocean’s role in regulating Earth’s climate. Turbulent mixing, triggered by gravitational instability, enhances the vertical transport of heat and carbon between the sea surface and deep ocean. Some of the less explored sources of turbulent mixing arise from non-linearities in the equation of state for seawater density. Specifically, the gain in density upon mixing, known as cabbeling, can create gravitational instabilities in vertical profiles that were stable prior to mixing. In this seminar I will outline the work done in my PhD thesis which investigates how cabbeling impacts thermohaline structure and mixing in the high-latitude oceans.
