Fisheries and Oceans Canada

Current research and/or projects

Dr Lefaivre is a research scientist within the Canadian Hydrographic Service at Mont-Joli. He is an expert in the field of physical oceanography, specifically in the analysis ocean data such as currents, temperature and salinity, and also in water level modelling in estuarine waters. He is the author or co-author of over forty scientific papers related to surface drift studies applied to oil spill, bacteria, fish larvae, variation in sea temperature, as well as the study of the variation of water level on daily, seasonal, and climate scale, in the estuary and Gulf of St. Lawrence. Currently, Dr Lefaivre is the chairman of the National Committee on Tides, Currents and Water level of the Canadian Hydrographic Service.
