RV Cefas Endeavour 04/17
|Ship name (ship code)||RV Cefas Endeavour (74E9)|
|Cruise period||2017-03-07 — 2017-04-05|
|Port of departure||Swansea, United Kingdom|
|Port of return||Lowestoft, United Kingdom|
1. Carry out an integrated monitoring survey of the Celtic Sea, south-western approaches and the western Channel using a random stratified survey design for the purposes of providing fish stock assessment data and the collection of associated ecosystem information.
2. Continuously log sub-surface (3m) salinity, temperature, fluorometry and other environmental data using the 'Ferrybox'. Additionally, a Flowcytometer (phytoplankton) and FlowCam (zooplankton) may be run in conjunction with the Ferrybox.
3. Record details of surface sightings of any marine mammals, sea turtles and large pelagic fish, and record observations on jellyfish aggregations.
4. Collect water samples for caesium & tritium analysis under SLA22 (T Bailey - Cefas Lowestoft).
5. Tag/release specimens of various commercially exploited skates (Rajidae) and other selected elasmobranches.
6. Collect specimens of selected species for ID purposes as well as length-weight measurements where still required.
7. Collect length and weight measurements of jellyfish caught.
8. Collect specimens of cuttlefish to aid identification and for Cefas on-going projects.
9. Collect other samples in support of active Cefas projects.
RV Cefas Endeavour will sail from Swansea on the 6th March. A shake-down tow will be carried out at nearest planned survey sampling location to fully test all survey sampling gear, equipment and software systems. Following this, the vessel will head towards the primary survey area of the western Channel completing other Celtic Sea sampling stations en-route. At each survey location, a series of sampling activities will be conducted that comprise deployment of 4m beams; CTD profiling using ESM2 logger and Niskin sampler; sediment sampling using Hammond grab; SPI camera deployment and 2m beam trawling. Upon completion of 81 sampling locations in this area, a further 50 sampling locations in the Celtic Sea and the South-West approaches will be sampled. It is anticipated that a mid-survey break will occur around day 13 of the survey (18th March) with the location likely to be Falmouth. This will allow for a changeover of scientific staff and vessel's officers and crew and for the vessel to take on fresh supplies as necessary. Upon completion of the survey, CEND will dock in Lowestoft on the 4th April and unloading of equipment will be carried out the same day.
