Cruise Narrative

Monday 6 May 2002. In preparation for the cruise, all DANI scientific crew were onboard by 2000 hrs when mooring components and the automated sampler were prepared for deployment. Following a talk on ship's safety and a demonstration of personal life saving equipment, the RV Lough Foyle departed Belfast at 2030 hrs and sailed overnight in a light breeze towards the mooring site at station 38A.

Tuesday 7 May 2002. The vessel arrived at the mooring site at 0600 hrs. The weather was dry with a light westerly breeze when work for the day started at 0745 hrs. The instrument mooring was recovered to ship deck at 0830 hrs. The mooring components were inspected for corrosion and replaced where necessary. The thermistor chain was removed from the mooring wire and temperature data downloaded. The CTD and fluorormeter were also removed, data downloaded and reprogrammed. The automated water sampler was removed and replaced with a similar pre programmed unit. Following sample removal from the "large volume" water sampler, the instrument was fitted with new sample bags, reprogrammed for daily sampling and attached to the mooring assembly. The mooring components, thermistors, CTD and fluorometer were then reassembled. The satellite tracking system was confirmed working and the mooring was successfully redeployed at1314 hrs on position 530 46l .865N 50 38l .114W. The rosette water sampler and zooplankton net were deployed and the survey continued to station 47 off the Drogheda fore shore, where the water and zooplankton sampling operations were repeated.

Work on the station was completed at 1600 hrs and the vessel sailed to dock in Belfast at 0030 hrs Wednesday.

Wednesday 8 May 2002. Work for the day commenced at 0800 hrs when equipment was dismantled and removed from the vessel for return transportation to Newforge Lane. The scientific crew disembarked at 1040 hrs.
