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.
