Oceanographic sampling of physical, biological and chemical parameters is performed biweekly at selected fixed stations and two to three times annually along selected fixed sections, as part of the Atlantic Zone Monitoring Program. The sampling consists at minimum of vertical profile of the entire water column, water bottle sampling at selected depths of nutrients, salinity and oxygen, vertical net tows for zooplankton. See: http://science-catalogue.canada.ca/record=b3951030~S6 for more details. The Atlantic Zone Monitoring Program (AZMP) was implemented in 1998 with the aim of increasing Fisheries and Oceans Canada's (DFO) capacity to understand, describe, and forecast the state of the marine ecosystem and to quantify the changes in the ocean physical, chemical and biological properties(i). A critical element of the AZMP involves an observation program aimed at assessing the variability in nutrients, phytoplankton and zooplankton. The overall aim is to identify fundamental relationships among elements of the planktonic ecosystem and establish how they respond to changes in environmental drivers(i). The AZMP derives its information on the state of the marine ecosystem from data collected at a network of sampling locations (high frequency sampling stations, cross-shelf sections, and groundfish surveys) in each region (Quebec, Gulf, Maritimes, NL) sampled at a frequency of biweekly to once annually.
