Study of the earth's magnetic field behaviour during the Quaternary as well as sedimentary processes, climate change and natural hazards.
The team at the Paleomagnetism and Marine Geology Laboratory at the Institut des sciences de la mer de Rimouski (ISMER) has extensive expertise in the study of diverse magnetic, physical and chemical properties of marine and lake sediments from both hemispheres, including from the Arctic and Antarctic. We use a comprehensive suite of instruments to perform detailed studies of sediment cores and conduct seafloor mapping. The team has gained cutting-edge expertise during expeditions to gather geophysical measurements and sediment core samples in sea and in lake environments using several types of corers and echosounders. This wide array of state-of-the-art laboratory and field instruments makes our laboratory a key leader in marine geology research projects, for both our national and international partners.
