Isotopic geochemistry applied to environmental research on natural resources development and basin analysis
Current research and/or projects
What is the focus of your research ?
I developed and supervised the stable isotope laboratory (Delta-Lab, GSC) for 28 years. The Delta-Lab is dedicated to environmental research aiming at understanding better the pollution impacts on air, soils, trees and water associated with the extraction of natural resources, evaluating the resource potential of sedimentairy basins, and helping promote the sustainable development of groundwater resources.
What is the significance of your research?
My research on the isotopic geochemistry of nitrates in anthropogenic atmospheric plumes, and tree-ring isotopic sequences allows understanding historical changes in air quality and soil chemistry during periods when instrumental measurements were not available. More specifically, my activities focus on the carbon and nitrogen cycles and metal deposition in peri-urban regions and industrialized sectors, to better understand the dynamic of these elements from emission sources to air, soils, groundwater and vegetation. My recent work on clumped isotopes in CO2 and carbonates is placing the Delta-Lab of the Geological Survey of Canada at the forefront of paleothermometry research on sedimentary sequences.
The research of my group has now provided the scientific community with tools allowing to distinguish between natural and man-made environmental effects. I am also part of international multidisciplinary teams working together to reconstruct the past thousand years of Northern Quebec climate which is a critical region for the hydro energy sustainability in Eastern Canada. Finally, I lead several scientific projects providing key information with respect to the sustainable development of non-conventional oil petroleum resources (oil sands), with the goal of providing non-bias recommendations concerning the environmental footprint of the extraction zones. My team develops new analytical protocols and is using novel approaches to distinguish natural contaminants from anthropogenic ones, and an array of new isotopic indicators, such as clumped isotopes of C and O, to help determine the paleothermal regime of sedimentary basins.
