Narrative

Endeavour sailed at 20:30 Thursday 5th Sept and transit overnight to the Warp SmartBuoy. A water sample was collected via CTD rosette before the SmartBuoy was be recovered and a replacement deployed. Another water sample was collected afterwards. After a 6 hour steam to the West Gabbard SmartBuoy the procedure was be repeated without incident. Endeavour moved to AWAC 3.1. where a 13hr ADCP survey was undertaken overnight. Water samples were collected before the minilander was recovered. As the ship manoeuvred to redeploy the northern guard was run over and badly damaged. It took over 5 hours and several attempts to recover the guard buoy during which two grapples were also lost. The guard was replaced with a spare and the lander eventually re-deployed before water and sediment samples collected. Endeavour moved to AWAC 4.1 to start the ADCP survey at 23:30. The ADCP survey was completed at 13:20 on 8th September. Water samples were collected before the minilander was recovered. A new minilander was deployed at 14:20. Water samples were taken over three separate CTD casts before sediment samples were collected. A multibeam survey was undertaken at AWAC 4.1 before returning to Lowestoft for the midnight tide but arrived to late for the pilot to accept us so we had to wait until morning. Endeavour docked at 11:30 on 09/09/13.
