In an effort to monitor the behavior of the world's oceans, Europe has committed to build the next Jason altimeter spacecraft -- a decision that should guarantee the continuation of a remarkable 18-year record of sea-surface shape until late in the decade, BBC News reported. The recent steady 3mm per year rise in global sea level has been tracked by the Jason series. The data has become invaluable to oceanographers, weather forecasters and climatologists.
