Since the discovery by J. E. Lovelock, R. J. Maggs and R. A.
Rasmussen, in 1972, of its ubiquity in sea water, dimethyl sulphide
(DMS) , a biologically produced sulphur compound, has been the
subject of continuously increasing interest by the scientific
community. DMS was immediately recognized as an important component
of the biogeochemical sulphur cycle, and is now indicated as the
second most important source of sulphur in the atmosphere, after
anthropogenic so emission from fossil fuel combustion and 2
industry. DMS reacts rapidly in the atmosphere where it is oxidized
to condensable acidic sulphur products; in fact, rainwater
acidification, observed in remote areas, is attributed to DMS
emissions. The hypothesis of a climatic role of DMS was made
already in 1983 by B. Shaw, and by B. C. Nguyen, B. Bonsang and A.
Gaudry. In 1987, a study appeared in Nature, in. which R. J.
Charlson, J. E. Lovelock, M. O. Andreae and S. G. Warren suggested
the possibility of a partial control of the climate by the
biosphere through a chain of processes, linking production of DMS
by marine phytoplankton with changes in clouds albedo. The
publication of this paper triggered a strong debate and stimulated
new efforts to describe the various aspects of the DMS cycle in the
environment. The paper was timely and added to the discussion on
the relative roles of atmospheric sulphur and greenhouse gases in
the Earth's radiative budget.
