| Purpose | Research |
| Objectives | The main objectives of the mission were:
- to obtain synoptic fall observations of the hydrography and the distributions of nutrients, phytoplankton, zooplankton and bacteria along three sections on the Scotian Shelf and one in Cabot Strait, i.e. to carry out the fall Atlantic Zone Monitoring Programme (AZMP). - to retrieve moorings and deploy moorings along the extension of the Halifax Section and to take hydrographic profiles and collect water samples at mooring stations. This part of the programme is in collaboration with members of the UK RAPID-WAVE (West Atlantic Variability Experiment) programme. All of the stations of the main AZMP lines were sampled, so that the first major objective, the core AZMP sampling, was successfully completed. All of the moorings on the extended Halifax line were successfully recovered and were successfully deployed, and the hydrographic and water sampling were carried out, so that the second major objective was also successfully completed. Additional stations were sampled and all objectives were achieved. The third leg of the mission was to the eastern Scotian Shelf, the Gully and Cabot Strait. In addition to the AZMP sampling along the Cabot Strait and Louisbourg Lines, 4 stations were sampled in the central Gully and Gully mouth. Throughout the cruise, except in the Marine Protected Area of the Gully, acoustic backscatter signals were collected at two frequencies to determine the vertical distribution and abundance of macrozooplankton and when the ship was underway, during the daylight hours, a survey for pelagic birds was carried out from the bridge. |
