| Cruise period | 1979-04-27 — 1979-05-07 |
| Status | Completed |
| Port of departure | Barry, United Kingdom |

| Purpose | Research |
| Objectives | 1. Study of the bacteria, lower and higher fungi present in sediments and in the water overlying the sediments using the S.M.B.A. multiple corer. Particular attention to be paid to the organisms concerned with organic degredation and nitrate reduction in the deep sea and shelf sediments. Analysis of water and sediment pore water for organic and inorganic nutrients. Rates of oxygen uptake, the uptake of selected carbon substrates and ATP levels measured. Continuous flow enrichment cultures using sediments from 5,000m were planned to be set up as soon as possible and to continue for the duration of the cruise in a study of bacterial growth on inert surfaces at low nutrient concentrations.
2. Sampling of the meiofauna of deep sea and shelf sediments using the SMBA multiple corer. Bottom photography of the corer in operation. 3. Bottom photographs of the wave energy station off South Uist, if time permitted at the end of the cruise. |
