<h4>Project Description</h4>
Eddying solutions from ECCO2 experiments are being used by members of the
<a 
href=
"http://cpt-emilie.org">Climate Process Team on Eddy Mixed Layer Interactions
</a> 
to diagnose fluxes of heat and buoyancy 
due to eddy processes in the global oceans. Results (such as 
the diagnosed eddy heat and temperature transports shown in the figures below) 
are being compared against observations, theoretical models and against very 
high-resolution process models. This work is leading to a more complete 
understanding of the role ocean eddies and mixed-layer processes play in 
setting the global ocean state.  <br>

Total poleward heat transport diagnosed from two years of the ECCO2 1/8th degree, isotropic grid MITgcm simulation (red line) and observational estimates with associated errors (black lines).

The application of ECCO2 high-resolution solutions can be seen in this <a href="CPT-EMILIE-2006.pdf">climate process team presentation</a> in which eddy transports from the explcitly 
resolved model are compared against existing and new parameterizations.
