RV Cefas Endeavour 2/06
|Ship name (ship code)||RV Cefas Endeavour (74E9)|
|Cruise period||2006-01-16 — 2006-01-22|
|Port of departure||Lowestoft, United Kingdom|
|Port of return||Lowestoft, United Kingdom|
The aim of this work is to describe the effects of fishing and environment on production and food web structure during a seasonal production cycle. This is the sixth of seven related cruises that have been scheduled for this purpose (the previous five were successfully completed in 2005). The data collected will be used to parameterise size-based food web
models and to describe how seasonal patterns of energy flow affect indicators of fisheries impacts on trophic structure, biomass and production.
The study will focus on the Silver Pit region of the central North Sea and the following work will be conducted:
1. Analysis of spatial and temporal variation in carbon and nitrogen stable isotope ratios close to the base of marine food chains (filter feeding infauna and zooplankton).
2. Analysis of relationships between body size, energy content and trophic level (from nitrogen stable isotope analysis) in space and time for zooplankton, benthic invertebrate and fish communities.
3. Analysis of relationships between body size and production for zooplankton, benthic invertebrate and fish communities.
RV CEFAS ENDEAVOUR will sail from Lowestoft on Ip/l/06. She will work in ICES area IVb (UK waters only) throughout the cruise and will dock at Lowestoft on 22/1/06.
