SUMMARY:Tracking Ice Sheet Retreat Using Cosmogenic Nuclides: A Virtual Seminar
DESCRIPTION:Professor Claire Todd\, California State University\, San Bernardino\nSponsored by the Southern California Section ACS\nApril 24\, 3-4 pm\, Online\, Free\, Registration required\n\nAbstract \nIce sheet retreat reveals underlying bedrock and strands glacially transported rock\, exposing these geologic materials to the cosmic ray flux. Geologists use the resulting cosmogenic nuclides in minerals to determine the timing and rate of ice sheet retreat. Studies across Antarctica reveal a range of ice sheet thinning rates over millennia and provide a valuable comparison to measurements of modern ice sheet change. This presentation will provide an overview of this geochronological technique\, and share field experiences and results from surface exposure age studies in East and West Antarctica. \nBiography \nDr. Claire Todd is Professor and Chair of the Department of Geological Sciences at California State University San Bernardino where she works with students to study cryospheric change in Antarctica and the Pacific Northwest. She has completed six deep field seasons in Antarctica.
