AB: We use a 15 year time serie of Topex/Poseidon data to detect internal tides on the Kerguelen plateau. In order to better represent and caracterise the properties of the internal tides, we use a high resolution model developed around the Kerguelen plateau and a dedicated data processing system also developed at LEGOS : the X-Track tool. Among other improvements, this software uses the high resolution regional MOG2D model for the high frequency de-aliasing, a refined data editing strategy in coastal ocean areas, a higher sampling rate processing (up to 4Hz), a local mean sea surface consistent with the altimetric data set.
