(Keynote Presentation) 'Only Connect.....'—Inspirations from the work of Robert Duce

The research of Robert (Bob) Duce is notable for several important reasons. The one I will concentrate on here is his ability to bring together work from several (traditionally separate) fields, hence the 'Only connect ....' of the title. This approach has been applied over a distinguished career to many different problems in the environmental sciences.

Although much of his work has dealt with marine particulates and rain and their role in exchanges between atmosphere and ocean, he has also had significant influence on the field of air-sea gas transfer.

I will expand on this through several examples including the transfer of selenium and iodine across the sea surface and its role in the global biogeochemical cycles of these two elements. Another example is the impact of iron additions on ocean productivity and resulting changes in the exchange of trace gases, including carbon dioxide and halogens, between ocean and atmosphere. In addition, new laboratory results on the deposition of ozone to seawater, its reactivity with surface components and gaseous feedbacks to the atmosphere will be presented.

Finally, Bob Duce's role in several major international projects will be illustrated via the SOLAS (Surface Ocean - Lower Atmosphere Study) project.
