| Objectives | Objectives
1. Obtain synoptic spring observations of the hydrography and the distributions of nutrients, phytoplankton and zooplankton along three sections on the Scotian Shelf and one in Cabot Strait, i.e. to carry out the Atlantic Zone Monitoring Programme (AZMP). 2. Retrieve and deploy moorings along a portion of the Halifax Line in the slope waters of the central Scotian Shelf and to take hydrographic profiles and collect water samples at mooring stations. This part of the programme was in collaboration with members of the UK RAPID-WAVE (West Atlantic Variability Experiment) programme. Additional objectives - Carry out hydrographic, chemical and biological sampling at stations in the Gully and Roseway Basin, on the Halifax Line Extension (to HL10), and at stations along transects across the NE Channel and St Anns Bank - Collect nutrients and hydrography across the Northeast Channel as part of NERACOOS Cooperative Agreement - Investigate the vertical distribution of macroplankton (e.g. krill) in NE Channel, the shelf basins, the Gully and Cabot Strait - Deploy/recover moorings at inner shelf stations of the Halifax Section (OTN moorings) - Deploy bottom mounted ADCP/microcat mooring and thermistor chain on St. Anns Bank - Identify and enumerate birds during transit between stations and lines - Collect and preserve water samples for analysis of carbon dioxide concentration - Retrieve three 'whale listening' moorings in the Gully region - Obtain some moving vessel profiler (MVP) transects during transits 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 RAPID moorings on extended Halifax Section were recovered and deployed. The hydrographic and water sampling associated with the mooring programme were carried out, so that the second major objective was largely successfully completed. Additional stations were sampled as required by the additional objectives stated above and all objectives were achieved. |
