Atlantic Zone Monitoring Program (PMZA-RIKI) 2015 to 2017: Biogeochemical Data

The Atlantic Zone Monitoring Program (AZMP) of Fish and Oceans Canada (DFO), or Programme de monitorage de la zone Atlantique (PMZA), includes a network of autonomous oceanographic buoys across the coastal waters of the Maritime provinces of Canada. The station named PMZA-RIKI just in front of Rimouski has been equipped with an autonomous buoy in 2002, including multispectral sensors dedicated to satellite validation of radiometric products. In 2015, a project was put in place to assess the quality of the radiometric measurements available at the station PMZA-RIKI in order to use these data for the validation of operational ocean color radiometric products. The station was visited on several occasions from 2015 to 2017 onboard DFO small (i.e. 30-foot length) craft boats.
