In this paper we describe the development of a program that aims at achieving the optimal integration of observed data in an oceanographic model describing the water transport phenomena in the Agulhas area at the tip of South Africa. Two parallel implementations, MPI and OpenMP, are described and experiments with respect to speed and scalability on a Compaq AlphaServer SC and an SGI Origin3000 are reported.
