Objectives | Objectives
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. During the first leg of the cruise the mooring work in the slope waters of the Halifax Line was done in collaboration with the scientists from the UK RAPID programme. Accompanying CTD profiles were collected and water sampling was also carried out along with some biological net sampling. | ||||||||||||||||||||||||||||||||||||||||||||||||
