Narrative (All times GMT)
RV Cefas ENDEAVOUR sailed from Lowestoft at 1030h 5 August. Onboard were 7 Cefas fisheries staff, and 1 student from the University of Southampton. Before work on the primary stations commenced, a 'shakedown' tow was carried out to allow for the deployment of the gear, to check that all sensors were working correctly and to allow scientists and crew to familiarise themselves with their particular work areas. A standard station consisted of a cast with a CTD and a 10-litre Niskin bottle, followed by a 30-minute tow with the standard IBTS rigged GOV, with a miniCTD attached. At the start of the survey, on every station, fisheries acoustic data were continuously collected at three operating freque
