The UTIG Discussion Hour is a weekly, flexible-format seminar hosted by UTIG and open to all members of our community. Presentations range from spotlighting new geoscience research to less technical talks sharing fieldwork excursions. See upcoming talks at our Events Calendar. Past talks are posted below and at our YouTube playlist.
