CASPO seminar: Jinbo Wang - "The cross frontal exchange near the Drake Passage"

8610 Kennel Way La Jolla, CA 92037, US
Event Description: 
"The cross frontal exchange near the Drake Passage”.

The Antarctic Circumpolar Current (ACC) in the Southern Ocean is
associated with steep isopycnals and large potential vorticity gradient,
which act as barriers to meridional tracer transport.  In order to
understand the tracer and energy balance of the Southern Ocean, it is
crucial to understand where and how the cross frontal transport occurs.
 The Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean
(DIMES) project was designed to answer such questions by conducting
anthropogenic tracer and subsurface float experiments together with
in-situ CTD and microstructure measurements near the Drake Passage. In
this talk, I will present the DIMES tracer measurements and discuss the
cross frontal transport near the Drake Passage using both DIMES tracer
and the supporting results from a suite of particle simulations in the
Southern Ocean State Estimate (SOSE). The Drake Passage is shown to be
associated with enhanced cross frontal exchange.
