PurposeResearch
Objectives1. To determine ocean-atmosphere exchanges of radiatively active gases, and the factors influencing such fluxes, over a wide latitudinal range.
2. To investigate the interactions between the biological, chemical and physical processes that control carbon fluxes in the euphotic zone.
3. To assess the impact of sea-ice on biogeochemical fluxes, in order to estimate the importance of climatic feedback effects.
4. To determine the export of biogenic material from the upper ocean and its subsequent fate.

Some ACCLAIM project work was carried out by Bob Spencer and Peter Foden. The purpose was to recover the Scotia Sea capsule near Signy, deployed in 1991. The island station at Signy was to be serviced and equipment left to enable the data to be forwarded to POL via the BAS computer links. The last aim was to recover a data capsule from MYRTLE which was deployed on the previous leg. See the cruise report for more information.
