The North Atlantic exhibits a high level of natural variability from interannual to centennial time scales, making it difficult to extract trends from observational time series. Climate models, however, predict major changes in this region, which in turn will influence sea level and climate, especially in western Europe. We welcome contributions from observers and modelers on the following topics: climate relevant processes in the North Atlantic including ocean-atmosphere interaction, interpretation of time series, the role of the meridional overturning circulation, and variability on a broad range of time scales.
Included are now the abstracts submitted to OS4.5 "Application of inverse methods to oceanography and paleoceanography" (co-organized)
