Champ magnétique terrestre de la géodynamo interne de la Terre (Glatzmaier et Roberts, 1995)

Mes projets de recherche en cours consistent principalement à reconstruire les variations d’orientation et d’intensité du champ magnétique terrestre au cours de l’Holocène à partir de séquences sédimentaires de l’est et de l’Arctique canadien. Ces reconstructions servent à déterminer la dynamique du champ magnétique terrestre à des échelles de temps encore pratiquement inexplorées, mais aussi à déterminer son influence sur le taux de production des isotopes cosmogéniques tel le 14-C et le 10-Be : deux isotopes généralement associés aux variations de l’activité solaire aux échelles de temps séculaires et millénaires. Mes travaux permettent aussi l’établissement de chronostratigraphies robustes par corrélation des courbes d’inclinaison, de déclinaison et de paléointensité. Finalement, à partir des différentes propriétés magnétiques, physiques et sédimentologiques de séquences sédimentaires, je développe des traceurs des variations climatiques ou environnementales ainsi que des catastrophes naturelles (séismes, glissements de terrain ou crues) au cours du Quaternaire.

Entrevues

Jacques Locat (Université Laval), Guillaume St-Onge (GEOTOP-ISMER-UQAR) et Alfonso Mucci (GEOTOP-Université McGill) ont été interviewés par Radio Canada (cf. émission radiophonique "Les années lumière" du 12 juin et Téléjournal du 22 juin). Les entrevues, effectuées à bord du Coriolis II, portent sur les évènements géologiques qui ont eu lieu dans le fjord du Saguenay et sur l’éventualité d’un tsunami dans le golfe du St-Laurent.
