Plan

CEFAS ENDEAVOUR will sail on 4 October and will return to Lowestoft on 14 October. Video data will be collected from cameras mounted on a towed sledge. On the Farn Deeps grounds, 110 stations will be visited (80 priority 1 stations; 8 priority 2 stations; 17 priority 3 stations and 5 additional stations) with the aim of recording a clear 10 minute continuous video transect of the sea bed at each.

If weather and logistics allow 36 stations on the Botney Gut Silver Pit grounds (21 priority 1 and 15 priority 2) will be visited and the same data collected.

All video will be analysed and the counts confirmed at sea.
