Study of the Northwest African upwelling zone using TOPEX/Poseidon and ERS-1 altimetry
Preliminary results are presented concerning the contribution of satellite altimetry to the study of the coastal upwelling phenomena. Geophysical data records of the TOPEX/Poseidon mission are used over the first three years of its operation and a complementary set of earth resource satellite (ERS)-1 orbit adjusted data using TOPEX/Poseidon as a reference. The repeat track of analysis of the sea level anomalies demonstrates that the seasonal sea level variability is in agreement with the observed coastal upwelling variability along the northwest African coast. In spite of the fact that the two satellites are designed for the study of the large and the mesoscale ocean circulation, and that the tidal corrections applied are not specifically developed for the study of the coastal areas, the preliminary results are encouraging and promise that satellite altimetry can become a helpful tool for studying the coastal area dynamic circulation.
