StatusCompleted
Port of departureFalmouth, United Kingdom
Port of returnSanta Cruz de Tenerife, Spain
PurposeResearch
Objectives1. To return to Great Meteor East (GME) on the Madeira Abyssal Plain to carry out follow-up studies of biogeochemical fluxes over the proposed radioactive waste disposal site.
2. To recover, service and redeploy sediment trap and transmissometer moorings at GME and make comparisons of pumped particle data with trap.
3. To complete a transect of stations along 26N taking particle water samples for chemical analysis to estimate fluxes.
4. To locate and sample plumes produced by hydrothermal venting from the TAG field on the mid-Atlantic ridge. The programme was to include studies on water and particle chemistry, microbiology and general biology (nekton).
