Short Biography

Carol Kendall has been a research hydrologist (isotope biogeochemist) in the National Research Program (NRP) of the U.S. Geological Survey since 1980.  She is a 4th generation Californian who got her BS and MS in geology at UC-Riverside, and later her PhD in geology (with emphasis on geochemistry) at the University of Maryland while working full-time at the USGS Headquarters in Reston, VA.  Since 1990, she has been the head of the USGS Isotope Tracers research project in Menlo Park, CA.  The purpose of this NRP project is to develop new isotope methods and applications to solve problems of national importance.  In so doing, she has worked in watersheds all over the USA, at scales ranging from small pristine catchments in the Rockies and Appalachians, to large wetlands like the Everglades, and to large human-impacted basins like the Mississippi. The main focus of her recent research is using a multi-isotope approach to investigate the effects of flow and nutrients on various ecosystem problems in the San Joaquin and Sacramento Rivers, their delta, and the San Francisco Bay.  Common aspects of most of her studies are: (1) that she usually piggybacks them on large-scale state and federal environmental monitoring programs (water quality, ecological, and atmospheric); and (2) that she uses a multi-isotope, multi-tracer approach for the various ecosystems studies, resulting in the development of many regional to continental-scale isoscapes.
