Using the sea level static assimilation technique, the thermohaline structure of an oceanic circulation numerical model is modified, which permits the inclusion of satellite data with sea level anomalies on the baroclinic fields. The oceanographic cruiser “Caribe October 2007” was planned with the specific purpose of making in-situ measurements coinciding with the surface track and close times of two passages of satellite JASON-1 over the Colombian Caribbean. The simultaneous measurements of the ocean temperature and salinity, together with the sea level obtained from the satellite, make possible the restoration of the density variations of the water column. The Princeton Ocean hydrodynamic Model (POM) was used to filter the ocean climate patterns, and to reveal the anomalies related with the synoptic state. The article proves the possibility of assimilating the thermohaline fields using the absolute dynamic topography measurements from satellites.Downloads
