A LANDSCAPE RESTORATION PUZZLE: WHEN “NATURAL” ISN’T WHAT YOU THOUGHT IT WAS
Friday, January 29, 2016 | 1:00 PM Eastern (10:00 AM Pacific)
Study of the processes that change and shape the earth’s surface shows the profound influences that human modification can have on landscapes at a regional scale. Hillsides erode through time and deposit sediment via rivers and streams to the valleys below. Human activity lends an imprint to these deposits that can be difficult to distinguish without careful investigation. Dr. Dorothy Merritts and her research collaborators have unraveled the natural and human processes that have shaped riverine landscapes in the eastern United States – and propose a surprising pre-industrial scenario that explains high sediment loads in the Chesapeake Bay and other water bodies. It also matters to how streams are restored. The webinar will look more deeply at her research and the fascinating story it weaves among geomorphology, ecosystems, and human history.
The Board will host a 60-minute webinar with an expert presentation. A question and answer period will follow, moderated by Board members and National Research Council staff.
Dr. Dorothy Merritts, Department of Earth and Environment at Franklin & Marshall College
Dorothy Merritts (B.Sc. Indiana University of Pennsylvania, M.Sc. Stanford University, Ph.D. University of Arizona) is a geologist with expertise in streams, rivers, and other landforms, and on the impact of geologic processes, climate change, and human activities on the form and history of Earth's surface. Her primary research in the eastern United States is in the Appalachian mid-Atlantic region, where she is investigating the role of human activities in transforming the upland woodlands and valley bottom wetland meadows of Eastern North America to a predominantly agricultural and mixed-industrial/urban landscape since European settlement. Associated with this work is developing new methods of wetland, floodplain, and stream restoration that rely upon geomorphic investigation. She also is using lidar to map the geomorphic evidence for continuous permafrost from the last glacial maximum throughout Pennsylvania and Maryland.

BESR's Inaugural Webinar
UNEARTHING CITIZEN SCIENCE
Friday, 5 December 2014 | 12:00 PM (EST)
Presentation: Citizen Science: an overview
Professor Muki (Mordechai) Haklay is a professor of Geographical Information Science (GIScience) at the department of Civil, Environmental and Geomatic Engineering, UCL where he co-direct the Extreme Citizen Science (ExCiteS) group (http://www.ucl.ac.uk/excites). The group aim is to enable any community, regardless of their literacy, to initiate and run citizen science activities.
Presentation: Citizen Science at the U.S. Geological Survey
David Applegate is Associate Director for Natural Hazards at the U.S. Geological Survey and is co-chair of the National Science and Technology Council's interagency Subcommittee on Disaster Reduction.
Susan L. Brantley is Distinguished Professor of Geosciences at Penn State University where she also serves as the Director of the Earth and Environmental Systems Institute. She currently directs an NSF-sponsored project called Shale Network that works to publish water quality and quantity data to the web in areas of shale gas development in the northeastern U.S.A.
