Abstract
This article explains a methodology to model the spatial structures present in sea surface temperature images, collected from oceanographic satellites, that allows the estimation of sea surface currents. An Eulerian velocity field is built under the assumption that the currents can be diagnosed by the geostrophic equation. The images are preprocessed using a multiresolution wavelet analysis that helps to extract the surface structures at a given scale. A first guess of the vector field is computed at isotherm edges and the whole map of vectors is reconstructed using vector spline interpolation techniques.
