The Climate of Antarctica and the Southern Ocean (CASO) program is the lead project in the International Polar Year Antarctic Ocean Circulation cluster. 

 The specific goals of the CASO ocean circulation cluster are:

1.     To obtain a synoptic circumpolar snapshot of the physical environment of the Southern Ocean (collaboration with other IPY activities will extend the snapshot to include biogeochemistry, ecology, and biodiversity).

2.     To enhance understanding of the role of the Southern Ocean in past, present and future climate, including connections between the zonal and meridional circulation of the Southern Ocean, water mass transformation, atmospheric variability, ocean-cryosphere interactions, physical-biogeochemical-ecological linkages, and teleconnections between polar and lower latitudes.

The idea of this website is to keep people updated on CASO activities, particularly the fieldwork.

See CASO Proposal for more information.
