| Objectives and Narrative |
Objectives
1. To deploy drifters in the region of the Firth of Lorn SAC in order to validate an oceanographic circulation model. 2. To perform supporting CTD survey. Narrative Scientists joined Alba na Mara at 1000 (all times GMT) Monday 6 October in Fraserburgh. After procuring fuel for the small boat Proteus, Alba na Mara sailed at 1000 and made passage towards the west coast. After sailing through the night, Alba na Mara anchored in the lee of Eigg at 1700 Tuesday 7 October. Passage resumed at 0430 the following day, when Alba na Mara proceeded to Oban, where she tied up at 1000. Two visiting scientists were picked up and a crew member attended the local hospital for necessary medication. Alba na Mara sailed again at 1115 and proceeded to the western entrance of the Gulf of Corryvreckan. After some initial assessment of tide, two drogued, GPS tracked floats were deployed. Subsequently Alba na Mara then proceeded to anchorage for the night in Loch Tarbert, Jura. The anchor was lifted at 0400 the following day, and Alba na Mara returned to the westerly entrance of the Gulf of Corryvreckan. After a short search for the two drifters released the previous day, a CTD section commenced at 0620 Thursday 9 October, and was completed by 0930. Alba na Mara then returned to the entrance to the Gulf. A further two drifters were deployed at the first CTD station occupied at the start of the day, at the eastern end of the CTD section. After deployment of the drifters, the first CTD station was reoccupied. Alba na Mara then returned to the drifters, and these were recovered on board by 1240. Alba na Mara then proceeded to a sheltered anchorage in the Sound of Mull for the night. Alba na Mara left her anchorage at 0600 on Friday 10 October and returned to the innermost end of the CTD section, westwards of the Gulf of Corryvreckan. Three drifters were released at this position at 0915, and a CTD cast was performed. Alba na Mara then followed the three drifters, performing CTD casts whenever possible. Mid-way through the day the three drifters were recovered and redeployed close to the centre of the Great Race. Once again, CTD casts were performed along the track of the drifters. Finally, the drifters were recovered at 1500 after which Alba na Mara made passage once more to an anchorage in the Sound of Mull. |
