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 sailed from Lowestoft at 16:00 05/06/10 after which a dynamic positioning assessment/ calibration exercise was carried out. The surveyor left the ship on the pilot boat at 20:30. From here CEFAS Endeavour transited east to a North Sea Benthos Station (NSBS). This station (NSBS 24) was abandoned after 6 no samples due to coarse substrate. At 22:00 CEFAS Endeavour transited south to the Inner Gabbard where a sidescan and multibeam survey was carried out. Initials problem with the tow cable resulted in the Edgetech dual frequency sidescan fish being changed for the Benthic 1640 sidescan fish. On completion of this survey a Hamon and Shipek grab survey consisting of 5 stations was completed.

CEFAS Endeavour then transited north east to NSBS 25 and NSBS 54. Samples were successfully collected at both stations. A test of all equipment (hired NIOZ corer, SPI camera and CTD rosette was then carried out at a site just North of NSBS 54).

CEFAS Endeavour then transited north east to the southerly tip of the North Sea Biogeochemical Transect (main
