The advent of satellite altimetry over the past decades has allowed global observation of the ocean with unique spatial and temporal coverage. These satellite data have had a profound impact on studies of the Southern Ocean, which is less well understood than other major oceans in the world. To allow the full exploitation of altimetric observations, any high frequency contribution has to be correctly accounted for. Tidal effects are the major component of the sea surface variability at high frequen-cies. Most of the ocean tide models are now consistent in the deep ocean at the centimetre level (LE PROVOST (2001)). The challenges for the new ocean tide models are to provide accurate solutions in shelf and coastal areas and at high latitudes, and especially beneath ice shelves, where large discrepancies between models still remain. The accurate know-ledge of the barotropic response of the ocean to the atmospheric forcing comes within the same scope of altimeter data investigation. The accuracy of ...
