Cruise Inventory Information

Long name RV Cefas Endeavour (74E9) cruise 3/07
Short name 3/07
Objectives and Narrative This is the first cruise of a series, an essential part of a project addressing the source, cycling and fate of nutrients (i.e. carbon, nitrogen, silicon, oxygen) in UK Shelf Seas, specifically the North Sea. It will examine the relative importance of the various ecosystem components, their degree of connectivity and their susceptibility to change due to environmental or human pressures. The project combines an intensive observational programme in the North Sea, with model development and operation. Three representative sites have been selected for detailed process studies (5 cruises per year for 2 years) of pelagic (water column) and benthic (seabed) food webs, with horizontal and vertical spatial sampling over a broader area being achieved using a variety of towed instruments, and the temporal range being extended using autonomous buoys and bottom landers. In situ observations will be supplemented by satellite imagery and data from other sources, such as the continuous plankton recorder (CPR) and Ferryboxes.

The specific aims of cruise Cefas Endeavour 0307:
1. Deploy Landers and Smartbouys are required at the three primary sites.
2. Sampling at frequent intervals (approx hourly) using CTD rosette at the 3 sites with LISST.
3. CTD casts for primary productivity estimates and deck incubations using 15N uptake.
4. Underway measurements for isotopic ratio work from continuous supply.
5. Trial the use of the plankton multinet.
6. Collect plankton samples for species composition using vertical nets.
7. Deployment of SPI camera over a wide range of sites to characterize intersite variability.
8. Undertake assessment of benthic flora/fauna assemblage using Jennings beam trawls.
9. Collect samples for isotope analysis of fish, fauna and flora using 2m beam.
10. Collect core profiles of nutrients, oxygen, chl-a. (NIOZ corer) and sediment profiles.
