    The aim of the project is to study the dynamics of the North Atlantic Ocean between 20 degrees N and 60 degrees N by performing experiments on the assimilation of altimeter data into a multilayered quasi-geostrophic (QG) model covering this basin. A major part of the circulation in this area is dominated by the Gulf Stream. Acknowledgments I'd like to thank Keith Haines for coming up with this project, and for his supervision throughout the development of the work here. Thanks also to Mike Bell at th.

In the model's formulation, the oceanic state evolution is defined on a regular grid through time integration of the equations.
