Samples were taken from all planned stations. Central Fladen survey included 28 planned stations. 25 planned stations in the southeastern corner of the site, known as the Central Fladen (Core) area Western Fladen site incorporated 22 primary and 17 contingency stations.The SE Fladen survey design included 29 primary and 21 contingency stations.In between the three sites, a series of additional stations were visited, providing a further 17 sampling stations. The aim of survey CEND 01/13X was to gather high quality evidence to confirm the presence of Priority Marine Features within three Scottish Offshore Nature Conservation MPA proposals within the Fladen Grounds Nature Conservation MPA proposals and provide evidence to allow comparison of benthic assemblages between the sites. The data were collected for the Marine Conversation Zones Project funded by the Department for Environment, Food & Rural Affairs (DEFRA).

Samples were collected from within a 100 m radius around the target location. For a few stations, samples were collected away from the planned station due to presence of oil and gas installations and the exclusion zones around them. On recovery, a photograph of the undisturbed sample was taken. The sample depth in the day grab was taken to estimate the volume of the sample. A sediment core was then taken from the sample and stored in a plastic tub for Particle Size Analysis (PSA) in the laboratory. The remaining sample was emptied in a plastic box and transferred to the sample processing area onboard the vessel. Benthic fauna were collected by washing the sample with sea-water over a 5mm and 1 mm sieve. The retained >1 mm fraction was transferred to a labelled container and preserved in 4% buffered formaldehyde for later analysis ashore. A 0.1 m2 mini Hamon grab fitted with a video camera , the combined gear being known as a ‘HamCam’. This allowed an image of the undisturbed seabed surface to be obtained for each grab sample. Samples were collected from within a 100 m radius centred on the target location. On recovery, the grab was emptied into a large plastic bin and a representative sub-sample of sediment (approx. 0.5 litres) taken for Particle Size Analysis (PSA). The sample was stored in a labelled plastic container and frozen ready for transfer to a laboratory ashore. The remaining sample was photographed and the volume of sediment measured and recorded. Benthic fauna were collected by washing the sample with sea water over a 1 mm sieve. The retained >1 mm fraction was transferred to a labelled container and preserved in 4% buffered formaldehyde for later analysis ashore. A visual assessment was made of the sediment type sampled by the grab and noted on the field records, assigning the sample to a Folk class and its equivalent EUNIS and Broadscale Habitat (BSH) sediment classes.
