PurposeResearch
ObjectivesThe general aim of the cruise was to identify species that are vulnerable to beam trawling disturbance and describe the structural and trophic changes that take place in benthic communities when vulnerable species are lost. The main objectives of the cruise were:
1. To complete a sidescan Questor Tangent survey in 3 boxes (each 2 x 1 nautical miles) to the south-east of the Dogger Bank, before and after experimental beam trawling.
2. To sample the benthic invertebrate and fish community with corers, grabs, dredges and beam trawls before and after experimental beam trawling.
3. To collect sediment cores, before and after experimental trawling, to assess changes in sediment quality and nutrient fluxes.
4. To collect fish stomachs for dietary analysis and invertebrate and fish tissue for stable isotope analysis.
