Narrative

Monday 24 June 2002. In preparation for the cruise, all DANI scientific crew were onboard by 1930 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 southerly wind towards the mooring site at station 47D.

Tuesday 25 June 2002. The vessel arrived at the mooring site at 0600 hrs. The weather was dry with a light southerly breeze when work for the day started at 0800 hrs. The mooring components were assembled and readied for deployment. The CTD and fluorometer were attached and the mooring deployed at 0851 hrs on position 530 44l .485N 60 03l .970W. Following the deployment of the rosette water sampler and zooplankton net the survey continued to the open sea mooring station 38A. On arrival the complete instrument mooring was recovered to ship deck at 1105 hrs. The mooring components were inspected for corrosion and parts replaced where necessary. The thermistor chain was removed from the mooring wire and temperature data downloaded. The CTDs and fluorormeter were also removed, data downloaded and reprogrammed. The sub surface automated water sampler was removed and replaced with a similar pre programmed unit. A second water sampler was positioned on the mooring to operate at depth 85 m. The mooring components, thermistors, CTD and fluorometer were then reassembled, the satellite tracking system was confirmed working and the mooring was successfully redeployed at1545 hrs on position 530 46l .795N 50 38l .122W. The water and zooplankton sampling operations were then repeated. Work on the station was completed at 1630 hrs and the vessel sailed to dock in Belfast at 1030 hrs.

Wednesday 26 June 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 1045 hrs.
