| Dorothy Merritts is an environmental geologist at Franklin and Marshall College in Lancaster, Pennsylvania. She has worked on mine reclamation, done research with the U. S. Geological Survey on earthquake hazards in California, and studied groundwater resources, streams, and soil processes. As an expert on flooding, she served from 1994 to 1996 on the National Research Council's Committee on Alluvial Fan Flooding, a committee selected to advise the Federal Emergency Management Agency on flood hazard issues. Andrew de Wet is an environmental geologist at Franklin and Marshall College in Lancaster, Pennsylvania. Trained as a petrologist, he has done field work in Greece, the United Kingdom, South Africa, and the United States, and approaches environmental issues from both a theoretical and a practical perspective. His interest in Earth system science focuses on land use and dynamic systems modeling. His research integrates remote sensing, geophysical techniques, and geographic information systems with field work and laboratory analysis. Kirsten Menking is a visiting professor of Geology at Franklin and Marshall College from Vassar College in Poughkeepsie, New York. Her research interests include using sediments to unravel the Earth's history of climactic change, linking paleoclimatic data to atmospheric and hydrologic processes, and analyzing the evolution of landforms in response to climatic and tectonic forcings. She has also conducted research in paleomagnetism and participated in a U. S. Geological Survey Project to study lake sediments and reconstruct cycles of glaciation in the Sierra Nevada. |
