| Status | Completed |
| Port of departure | Sullom Voe, United Kingdom |
| Purpose | Research |
| Objectives | 1) To carry out a sampling of the benthic populations of Sullom Voe, with special attention to the distribution, density, diversity, and biomass of these populations. This survey, an extension of the 1975 preliminary survey, had as it's purpose the provision of a more detailed information on the benthic populations of certain 'sensitive' areas which are likely to reveal future interference with the environment
2) To collect samples of sediment and fauna for hydrocarbon and heavy metal analysis 3) To conduct a search for the recovery of a box corer lost during the April 1975 survey An additional member of staff joined the crew in Sullom Voe on the 01/06/1976. |
