WECCON is a longterm project in the context of the AWI research programme which was previously MARCOPOLI and since 2009 is PACES. It aims to study large scale processes and long-term variations of convection in the Weddell Sea and the Weddell gyre.
It provides contributions to CLIVAR , iAnZone and the IPY project CASO.

The Antarctic ocean contributes through atmosphere-ice-ocean interaction processes by water mass transformation to the variability of the climate system. A major part of the formation of deep and bottom water of the world ocean occurs in the Weddell Sea.

WECCON aims:

• to investigate processes which occur in the Weddell Sea to form deep and bottom water
• to study the influence of exchanges between the Antarctic Circumpolar Current and the Weddell Sea on the water mass transformation.
