DISCO was an integrated, multidisciplinary Lagrangian study of the routes, rates and controls on the biogeochemical cycling of dimethyl sulphide (DMS) within a bloom of the coccolithophorid alga, Emiliania huxleyi.

DISCO was funded principally by the Natural Environment Research Council (NERC) and by the UK Defence Evaluation Research Agency (DERA) — now QinetiQ.

BODC provided DISCO data management services and collated the available data sets. The research involved 28 scientists and technicians from eight separate institutions.


The cruise took place between 05 June and 01 July 1999 in the northern North Sea. The biogeochemical process study was preceded by a 52 000 km2 survey of the region in order to locate an Emiliania huxleyi bloom suitable for study. The bloom chosen was labelled with sulphur hexafluoride (SF6) within a patch of 40 km2 initially centred on 58° 56' N, 2° 52' E. During the process study the patch drifted in a south-easterly direction and was eventually subducted under Norwegian coastal water at the end of the process studies on 26 June.

The process study comprised of
