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 second leg of the mission was to the western Scotian Shelf and Northeast Channel, and sampling was along the Browns Bank and PS line. There was also sampling along the shelf portion of the Halifax section, for which the stations in the slope waters had been sampled on the first leg. The PS (Peter Smith) Line was run in order to examine the flux of nutrients into and out of the Gulf of Maine via this route (no project report provided). As well as standard AZMP sampling, on these three lines the MVP (Moving Vessel Profiler), fitted with an LOPC (Laser Optical Plankton Counter), was towed between adjacent stations.
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.
