Cruise Inventory Information

Long name RV Cefas Endeavour (74E9) cruise 8/07
Short name 8/07
Objectives and Narrative Aims

1. Trial the use of the Plankton multinet.
2. Recover and redeploy landers at the three sites and additionally the smart buoys at the north dogger site.
3. Perform scanfish tows to give the water column context.
4. Sampling at frequent intervals (approx hourly) using CTD rosette at the 3 sites with LISST
5. CTD casts for Primary productivity estimates and deck incubations using N15 uptake.
6. Underway measurements for isotopic ratio work from continuous supply.
7. Collect Plankton samples for species composition using vertical nets.
8. Deployment of SPI camera over a wide range of sites to characterize inter site variability
9. Undertake assessment of benthic flora/fauna assemblage using Jennings beam trawls
10. Collect samples for isotope analysis of fish, fauna and flora using 2m bean
11. Collect core profiles, of nutrients, oxygen, chl-a. (NIOZ corer) and sediment profiles.
12. Undertake experiments on productivity and grazing at the three sites.

Narrative

Due to the problems with a crane, which hindered loading, Endeavour departed at revised time of 20:30 with a pallet truck for moving the Nioz corer and other heavy gear around the starboard area. The ship continued to the Gabbard, where a CTD was undertaken with nets, further nets where taken uneventful, and subsequent nets were performed at the half way stage to the Sean gas field site.

At the Sean gas field the recovery of the mooring was problematic. It is on position but after grappling it and retrieval the ground line and anchor, it is clear that serious corrosion had occurred. Following this, a CTD was taken to collect bottom waters and NIOZ coring was under taken until 20:00. There was problem with the CTD winch starting to haul in of its own accord. The emergency stop was pressed and worked. CTDs were then taken from 21:00. The cycle of hourly CTDs and Nets every 6 hours was undertaken until 09:00, when further grappling took place for
