Argo float data have been used in a Bernoulli Inverse method to calculate the dynamic sea surface height of the North Atlantic at weekly intervals. The results have been tested against satellite altimeter data and model data with encouraging results. The method is currently being expanded to include altimeter data directly into the analysis. Work is also being undertaken to examine the errors involved in the scheme and to look at the possibility of the use of other conservation properties.
