image: This is the "Atlantic Compass," one of the ships of Atlantic Container Line Inc. Container vessels like this one, sailing regular routes in the North Atlantic have been fitted with sensors for measuring carbon dioxide in surface seawater. Regular data from a network of such ships can be combined with satellite measurements to produce accurate maps of the flux of carbon dioxide between ocean and atmosphere over the entire North Atlantic, enabling changes in this flux to be observed from season to season and year to year. This image relates to an article that appeared in the Dec. 4 ssue of Science, published by AAAS. The study, by Dr. A.J. Watson of the University of East Anglia in Norwich, UK, and colleagues, was titled, "Tracking the Variable North Atlantic Sink for Atmospheric CO2." view more
