Objectives | Aims
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 head for the Sean Gas Field site. Work will commence here, Tuesday 22nd First an attempt will be made to recover the mooring using the granton trawl. The following activities will be undertaken in roughly this order CTD and nets. NIOZ cores Sediment Flume studies Mooring deployment Sediment Flume studies Hyperbenthic sledge Flume studies SPI camera deployment. CTD and NETs Aiming to finish by approx 20:00 Wednesday 23 There would be direct passage to the Oyster ground site arriving approx 04:00 CTD and nets. Mooring recovery (lander only) Sediment Flume studies Mooring deployment (lander only) Hyperbenthic sledge CTD and NETs Sediment Flume studies BIONESS :- MultiNet SPI camera deployment. NIOZ Sediment Flume studies CTD and NETs Aiming to finish by approx 22:00 (Wednesday) Passage on to the Dogger Bank with a scanfish section starting on the Dogger Bank. Thursday 24th Approx (0600) A long - Scanfish section North would be continued for approx 16 hrs (112 nm). Friday 25th Approx 12 CTDS for productivity and SPI would be undertaken back along taking approx (18 hrs) Sediment Flume studies on site at Dogger Saturday 26th CTD and NETs Mooring recovery (Smart buoy and lander) Sediment Flume studies SPI camera deployment. NIOZ Mooring deployment (Smart buoy and lander ) Hyperbenthic sledge BIONESS :- MultiNet Sediment Flume studies CTD and NETs Sunday 27th Survey of area with NIOZ and SPI for comparative impact of trawl work. Monday 28th 1600 :- depart for Lowestoft Tuesday 29th 1600 arrive Lowestoft. | ||||||||||||
