Narrative

RV Cefas ENDEAVOUR sailed from Lowestoft at 1300h 5 August. Onboard, together with the normal compliment of 7 Cefas staff for the fisheries work, were 2 students from Exeter University, 5 scientists carrying out environmental aims and Remment ter Hofstede, chair of the IBTS Working Group, joining us as an observer. 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. On every station fisheries acoustic data were continuously collected a
