In order to guide physical investigations, characterize the structure ofmodel biases, and assess the impact of numerical and physical choices, DRAKKARsimulations are evaluated against altimetric sea-level anomalies (AVISO: 1993-present,see Poster by Penduff et al), and temperature/salinity profiles (ENACT/ENSEMBLES:1956-present). Model outputs are first sub-sampled like actual observations to buildaltimetric and hydrographic "synthetic observations". Real and synthetic observations andmore integral quantities (mixed layer depth cycle, heat/salt contents, etc.) are thencompared over various regions, periods, and timescales. This study presents themethods and a validation of DRAKKAR simulations with respect to hydrography.
