Cruise Inventory Information

Long name RV Cefas Endeavour (74E9) cruise 17/07
Short name 17/07
Objectives and Narrative Aims

Overall aims of this series of cruises were to investigate:
1. Pelagic food webs, water column measurements
2. Hydrography and seawater chemistry
3. Community structure
4. Phytoplankton and microbial production
5. Grazing impacts
6. Mesozooplankton secondary production
7. Vertical flux and budgets of carbon
8. Benthic food webs, sediment processes, exchanges across the interface
9. Sediment Profile Imagery
10. Advection in coarse sediments
11. Resuspension events

Narrative

The Endeavour sailed Thursday 10:30 and headed for the West Gabbard where a CTD and nets (500, 270, 200, 50um), 200 x 2 for Ben, 200um for Swier. We then steamed north towards Sean Gas Field collecting surface water and 2 x 200um nets en-route

Sean Gas Field
The guard buoy is missing! The Hyperbenthic Sledge worked okay and collected good samples after towing 1 minute at around 2kts (0.3kts over the ground). The tow cable was straight up and down so we only deployed 50m rather than the prescribed 3x depth which would have been 90m. The Bioness Multinet would not communicate with the PC so we gave up trying at midnight and switched to the Multibeam grid. The 10 SPI camera dips were between 06:30 and 07:30, then a CTD cast for large volume bottom water. The NIOZ coring commenced after a 1.5hr delay whilst seized components on the corer were released, and was finished just before lunch. The gantry wires were changed over to the CTD ready for the afternoon start of the 24 hr anchor stn. The Bioness Multinet again failed to communicate with surface PC and was sidelined for further tests. The benthic sledge was successfully deployed for 1 min tow. The 24hr CTD station started at about 15:50 with full experimental station. There was a brief delay as the CTD winch wire slipped in between the roller and the sheaf and had to be freed. The 2m ring net and the benthic sledge was deployed between casts during the evening.
