ObjectivesObjectives

1. 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).

2. to retrieve moorings along a section (SS-B) across the slope waters of the central Scotian Shelf, to 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.

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. At each station there were vertical LOPC drops using a second borrowed device, so that there could be a comparison between the number of particles counted by each sampling method. Also during this leg of the cruise, samples of stage V C. finmarchicus were collected for lipid analysis.
