1. To obtain estimates of the abundance and distribution of Nephrops burrows in the Fladen Ground, The North Minch, the South Minch, in the Firth of Clyde and at Devil's Hole. If time permits stations in the Sound of Jura and at the Noup will also be surveyed.
2. To use the TV footage to record occurrence of other benthic fauna and evidence of commercial trawling activity.
3. To collect sediment samples at each station.
4. To carry out trawling for Nephrops, based on one haul in each sediment stratum in each of the main survey areas, and to obtain samples of Nephrops for size composition analysis.
5. To collect samples of Nephrops for comparison of reproductive condition and morphometrics in each of the different survey areas (Functional Units)
6. To deploy the box corer sediment sampler in the Clyde on several occasions, and to resin cast burrows found within the samples.
7. To carry out trials on the new swathe system whilst in the Clyde.
8. To collect EK60 Roxann data throughout the cruise.
All scientific staff were on board FRV Scotia by 11:00 on Friday 5 June 2009, after which the vessel sailed at 12:30. Scotia headed for the Southern Trench in the Moray Firth, where a training session involving the deployment and recovery of the TV sledge was undertaken. Following this, Scotia made way to the Fladen grounds arriving there at 22:00. All staff were present at the first station; however, the positioning of additional equipment on the sledge and difficult sea conditions resulted in the sledge making poor contact with the seabed, and TV operations were postponed until daylight when the sea had settled and the equipment issue was addressed. Over the next three days, Scotia generally worked in an anti clockwise direction around Fladen with a fishing trawl in the evening of each day. On the night of 8 June, after fishing was completed, the trawl was streamed out and towed with the cod end
