| Objectives | 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 All times GMT Sail from Lowestoft at 18:00 and collected first water sample for Laura. Made good time to the West Gabbard site. Attempt to collect a CTD but the Surefire is not working. Collect 270, 200 and 50um ring nets, then 2 x 200m nets for Ben. Head for the Sean Gas Field site (SG). Collect water and nets en-route. Arrive SG at 05:00 16th May, start using Granton trawl to recover lander. 08:00 Disturb the lander to release the recovery rope but collect the guard buoy and drag it NE. Release the guard buoy and start SPI drops at 09:00. CTD (Surefire has been fixed) to collect large volume of bottom water for Elke's sediment incubations. Start NIOZ coring just before lunch and carry on until 14:00. Two minor injuries were sustained to staff using the springs on the NIOZ shoes. The 24hr water cycle was started at approx 14:30, with subsequent near hourly CTD casts for LISST profiles and 6 hourly "full stations". The profile at 19:30 was missed as we successfully recovered the lander and guard buoy instead. 22 CTD casts (water at a minimum of 3 depths) and 4 SBS water samples were collected 1m from bottom, during the 24hr period. The lander was re-deployed at 12:15 (53 09.97N 02 48.46E) and the guard buoy at 13:15. Many nets were hauled and the Satlantic profiler was deployed a few times too. Between 15:00 and 17:00, we collected phyocystis soup in the 2m ring net for Ben. After tea 5 x 2m beam trawls for Karema, then 3 x 2m beam net hauls for Ben | ||||||||||||
