The ACCUA project (funded in the framework of the Italian Antarctic Research Programme, PNRA) was aimed at analyzing and interpreting oceanographic data gathered in previous PNRA Antarctic expeditions through a combination of innovative data analysis methods (based on in situ observations and satellite data) and the use of an ocean circulation model of a wide sector of the Southern Ocean. The main achieved results are: - the identification of the ACC frontal variability from in situ and satellite altimeter data; - the observation-based reconstruction of the temperature and salinity fields and associated estimates of the upper mixed layer depth in the Southern Ocean; - the reconstruction of the 3D circulation along the New Zealand - Antarctica transect; - the identification and analysis of the intrinsic component of the ACC variability based on numerical simulations with stationary forcing; - the analysis of the mesoscale dynamics and its impact on the large scale circulation. In this presentation these results are summarized and their interrelationships are discussed.
