Geoscientists from the North-Central U.S. and beyond will convene at the Iowa State University Conference Center in the Scheman Building in Ames, Iowa, on 16-17 April, for the 52nd Annual Meeting of the North-Central Section of the Geological Society of America. Hot topics in geoscience will be discussed; new research findings on glacier flow, agricultural water quality, and emerging contaminants in the environment will be presented; and Iowa’s unique geologic and hydrologic features will be explored. The event is expected to draw more than 600 attendees from a variety of geoscience and related disciplines.
Featured speaker: Dr. Isabel Montañez, President of the Geological Society of America and Chancellor’s Leadership Professor of Geology at the University of California, Davis, will present a talk titled “Deep-Time Insight into Earth’s Future.” She will use three past climate events — abrupt greenhouse gas-forced warming of the Paleocene-Eocene Thermal Maximum (55 Ma) and Triassic-Jurassic boundary (200 Ma) and the turnover of the penultimate icehouse to permanent greenhouse conditions (300 Ma) — to illustrate how greenhouse-gas-forced climate change has unfolded in the past. The talk will begin at 5:45 p.m. on Monday, 16 April, in Benton Auditorium.
Book Signing: Dr. William Alley will sign copies of his (and his spouse’s) latest book, High and Dry: Meeting the Challenges of the World’s Growing Dependence on Groundwater. Dr. Alley is the former Chief of the Office of Groundwater in the U.S. Geological Survey and is currently Director of Science and Technology for the National Ground Water Association. Dr. Alley will sign books beginning at 7 p.m. on Monday, 16 April, in the first floor lobby. Books will be available for sale.
