The software for the global analysis method has been developed by P. Sicard. We wish to thank P. Gaspar, F. Hernandez, and G. Larnicol for useful discussions on this work. The Canary study was supported by SHOM under Contract CLS/SHOM 96.87.015.00.470.29.45 and by the MAST CANIGO project of the European Union (MAS3-CT-960060). The global analysis study is part of the AGORA project, supported by the Environment and Climate program of the European Union.
