Estuary and Gulf of St. Lawrence Marine Macroalgae Data Base (1933-2012)
This database gathers available and accessible information on the composition and distribution of marine macroalgae beds in the intertidal and infralittoral levels along Québec coasts. The current database includes information about the seaweed biomass and its presence or absence for the period from 1933 to 2012. The marine macroalgae database was built by Dr. Anissa Merzouk as an activity associated with the NSERC Industrial Research Chair for Colleges in the Conversion of Marine Macroalgae from the Cégep de la Gaspésie et des Îles (Merzouk, 2016) in close collaboration with Merinov and the Ministère de l’Agriculture, des Pêcheries et de l’Alimentation (MAPAQ). For more information, please see the data context.
