DESCRIPTION:The Southern Ocean is an important component in th
 e global climate system\, and some of its dominant
  features are the deep reaching jets of the Antarc
 tic Circumpolar Current\, which we expect to corre
 spond to thermohaline fronts. I used GMM (a soft c
 lustering technique) on\na hindcast model of the S
 outhern Ocean. I show that the boundaries between 
 GMM clusters are similar to other definitions of S
 outhern Ocean fronts\, with some advantages. This 
 method may be a promising way of turning model dat
 a into frontal positions to probe the possible eff
 ects of climate change on the Southern Ocean. The 
 talk would aim to be useful for those interested i
 n using clustering on a new data set\, or climate 
 model intercomparison. Some of the results are sti
 ll tentative and I would appreciate robust feedbac
 k.
