Objectives1. To continue the seasonal benthic sampling programme at the SMBA Permanent Station (54º 40'N, 12º 10'W) and in the vicinity of Station 'M' (57º 18'N, 10º 23'W).
2. To spade box core at a series of stations for quantitative analyses of deep sea fauna. At selected stations a subdivided box core was to be employed.
3. To spade box core at selected stations. These cores were to be subcored by P. Meadows and S.J.Wakefield for geotechnical, microbiological and sediment respiration analyses (PM & JT) or for geochemical analyses (SJW). The residue of the box core was sieved for fauna.
4. To use the stereocamera at several stations to obtain a photographic record of the sea bed.
