Although dust seems like a small component of the Earth’s ecosystem, it provides essential nutrients to ocean and terrestrial environments. Dust source activity, and dust transport and deposition are highly variable on timescales ranging from minutes to centuries to millennia depending on climate, landscape evolution and human activity. Dr. Aciego will present three case studies, examining the modern, ice core, and geologic record of dust sources and deposition through the use of physical and chemical characterization of the dust.
All talks are free and refreshments will be served. Visitor parking for the seminars (Central Campus) is across the street from Weiser Hall (formerly the Dennison Building) in the U-M Church Street parking structure. There is a $2.00 parking charge implemented by U-M Parking Services. For more information regarding the Saturday Morning Physics series, click here, or call 734.764.4437.
