Cruise summary report
|Ship name (ship code)||RV Cefas Endeavour (74E9)|
|Cruise period||2010-06-15 — 2010-06-21|
|Port of departure||Hartlepool, United Kingdom|
|Port of return||Hartlepool, United Kingdom|
1. Undertake detailed evaluation of sediment and seawater at three established sites in the North Sea representing different ecohydrodynamic units.
2. To survey dredged material disposal sites at Inner Gabbard, Tees (Inner and Outer), Souter Point, North Tyne for benthos, trace metal and organic contaminants in sediments, using grabbing and coring. At a number of sites various acoustic methods will also be used. Potential effects of Swanage Bay disposal site on the Dorset coast SAC will be assessed using a combination of underwater camera and grab techniques.
3. To sample representative CSEMP stations using grabbing, coring, and trawl methods. Samples will be later analysed for trace metal and organic contaminants, litter and epi-, macro- and meio- fauna.
4. To collect biological and physical samples using the Day grab from historical North Sea Benthos Stations
CEFAS Endeavour departed Hartlepool at 05:00 15/06/10 and transited to the Tees dredge disposal site and carried out the Day grab survey. On completion of this survey a multibeam survey was conducted. During this survey the dredger Cleveland County was observed actively disposing in the south west corner of the disposal site (16/06/10). During transits between stations a wreck was identified as a potential multibeam calibration site.
On completion of this survey CSEMP station 295 was collected before CEFAS Endeavour proceeded in a northerly direction to Souter Point dredge disposal site where Day grab, Nioz, SPI, multiBeam and sidescan surveys were successfully carried out.
CEFAS Endeavour then proceeded in an easterly direction collecting samples from CSEMP station 245 and NSBS 4 before transiting back inshore to begin work at the North Tyne dredge disposal site and former sewage sludge transect. On completion of this work CEFAS Endeavour transited south to the previously identified wreck where a full multibeam calibration survey was carried out.
On completion of the multibeam calibration exercise CEFAS Endeavour transited back to Hartlepool, docking at 10:00 19/06/10.
