| Status | Completed |
| Port of departure | Lowestoft, United Kingdom |
| Port of return | Lowestoft, United Kingdom |
| Purpose | Research |
| Objectives | The aims of this cruise were:
(1) to describe the impacts of trawling disturbance on the structure and productivity of benthic communities; (2) to examine the effects of fishing on the trophic structure of fish communities; (3) to describe spatial variation in carbon, sulphur and nitrogen isotopes at the base of estuarine and marine food chains. Specific objectives were: (1) To sample infaunal and epifaunal invertebrates at a series of sites subject to different levels of trawling disturbance. (2) To sample infaunal and epifaunal invertebrates and fish for food web studies. (3) To collect benthic invertebrate species for stable isotope analysis. |
