PurposeResearch
ObjectivesAims

1. Recover and redeploy landers at the three sites and additionally the smart buoys at the north dogger site.
2. Deploy sediment flume instrument for resuspension studies
3. Perform scanfish tows North of the Dogger Bank to give context for productivity
4. CTD casts for Primary productivity estimates and deck incubations using N15 uptake.
5. Undertake experiments on productivity and grazing at the three sites.
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 to investigate the impact of trawling
9. Collect core profiles, of nutrients, oxygen, chl-a. (NIOZ corer) and sediment profiles.
10. Deploy BIONESS multinet sampler for zoo plankton at selected sites.

Plan

Weather permitting Endeavour will sail at approximately 21:00 (GMT) on 21st April and
