Cruise summary report
Cruise Info. | |
Ship name (ship code) | RV Cefas Endeavour (74E9) |
Cruise identifier | 7/07 |
Cruise period | 2007-04-06 — 2007-04-12 |
Status | Completed |
Port of departure | Portland Harbour, United Kingdom |
Port of return | Portland Harbour, United Kingdom |
Purpose | Research |
Objectives | The work will (a) describe the impacts of trawling disturbance on the structure and productivity of benthic communities (b) examine the effects of fishing on the trophic structure of fish and invertebrate communities (c) describe spatial variation in carbon, sulphur and nitrogen isotopes at the base of marine food chains. The work is being carried out in support of project MF10-1:
a) To sample infaunal and epifaunal invertebrates at a series of sites subject to different levels of trawling disturbance for production studies. b) To sample infaunal and epifaunal invertebrates and fish at a series of sites subject to different levels of trawling disturbance for food web studies. c) To collect fish and benthic invertebrate species for stable isotope analysis RV CEFAS ENDEAVOUR will sail from Portland on 01 April and steam westwards to undertake sampling on the survey grids in the western English Channel and south-western Approaches. Sites will be sampled with 2m-steel beam trawl, 4m beam trawl, Agassiz trawl and either a grab or corer. |
