This is the third in a series of cruises being carried out over five years in the South-Western Approaches, in support of MF1001. The results of this work will describe the effects of fishing and the environment on production and food web structures. The specific objective of this cruise was: (a) Describe the impacts of trawling disturbance on the structure and productivity of benthic communities (b) Investigate sediment chlorophyll 'a' levels to allow comparisons with surface chlorophyll levels available via satellite imagery Narrative The scientific staff joined CEFAS ENDEAVOUR early evening (approx. 17:00 GMT) on Sunday 4 May, after being transported out to the ship via the port vessel from Portland harbour. Once all the staff were on board, CEFAS ENDEAVOUR steamed south westwards overnight to the first chlorophyll grid station. Sampling started at 07:00 the following day (Monday 5 May) at station C1 where seven successful replicate deployments were made with the mini Hamon grab. The samples were sieved to obtain the benthic infauna and the fauna frozen for later analysis. A further single NIOZ core was also taken and the sediment collected was sub-sampled for chlorophyll 'a', porosity, sediment granulometry and meiofauna. CEFAS ENDEAVOUR then proceeded on to stations C2 and C3 collecting a single NIOZ core at each, before proceeding to stations C4 and C10 where a single NIOZ sample was collected at each, along with seven replicate mini Hamon grab samples. Work at the final station of the day (C9) was completed by 20:50 with the successful retrieval of a NIOZ core sample. CEFAS ENDEAVOUR then steamed north overnight to station C5. Between 07:00 and 12:23 on 6 May, 4 chlorophyll stations (C5, C6, C7 and C8) were completed, after which CEFAS ENDEAVOUR steamed southeast to the first mini Hamon grab box at South Eddystone, completing seven valid replicate drops to collect benthic infauna, at each of the four stat |
