Distribution of subsurface and water column gases were mapped, with gas samples collected for composition and isotop analysis. Epifauna with symbiotic autotrphic bacteria were also studied to establish thier role in the ecosystem.

The first leg was conducted from 10-20th August 1990 and the second from 20-28 August 1990. Experts from multiple disciplines carried out the work and analysed the data. Details of the participants of each leg can be found in the report, as can detailed notes of the cruise.
