l’Ordre des Palmes Académiques, and he is a fellow of the International Association of Geodesy. He received his Ph.D. in space geodesy from Paris Observatory, and his habilitation (2nd doctorate) from Paris University VI.

GEOFFREY BLEWITT is a research professor with joint appointments at the Nevada Bureau of Mines and Geology and the Seismological Laboratory of the University of Nevada, Reno. Previously, he was a professor in the Department of Geomatics at the University of Newcastle upon Tyne, England. Dr. Blewitt’s research focuses on space-based geodesy and the application of very high precision GPS to earth science. Dr. Blewitt is a fellow of the American Geophysical Union and the International Association of Geodesy. He received his B.Sc. in physics from Queen Mary’s College of the University of London and his Ph.D. in physics from the California Institute of Technology.

WILLIAM E. CARTER is an adjunct professor in the Department of Civil and Coastal Engineering at the University of Florida and a professor in the National Center for Airborne Laser Mapping (NCALM). Dr. Carter’s current research interests focus on the use of advanced geodetic techniques to monitor the time variations of the orientation, gravity and topography of the Earth with sufficient accuracy to refine and discriminate among earth models and geodynamical theories. Dr. Carter previously held a range of positions at NOAA, including chief of the Geoscience Laboratory, chief of the Advanced Technology Branch, and chief of the Gravity, Astronomy, and Space Geodesy Division of the National Geodetic Survey. Dr. Carter received his B.S. in Civil Engineering from the University of Pittsburgh, his M.S. in Geodetic Sciences from the Ohio State University, and his Ph.D. in Civil Engineering from the University of Arizona.

ANNY CAZENAVE is a Senior Scientist at the Laboratoire d’Etudes en Géophysique et Océanographie Spatiale and Centre National d’Etudes Spatiales, Toulouse, France. Her research interests include satellite geodesy and applications to solid Earth, observation and climatic causes of sea level change, and large-scale land hydrology. Dr. Cazenave’s recent past and present international responsibilities include memberships on the Earth Sciences panel of the European Research Council, on the scientific panel of GGOS (Global Geodetic Observing System), and on the IPCC Working Group I (as lead author for Ocean climate and sea level; 2004–2007). She is past International Secretary of the American Geophysical Union (2002–2006), and past president of the geodesy section of the European Geosciences Union (1999–2004). Dr. Cazenave is a fellow of the American Geophysical Union, member of the French Academy of Sciences, and a foreign member of the U.S. National Academy of Sciences.

HERB DRAGERT is a senior research scientist with the Geological Survey of Canada and also holds an adjunct professor position with the School of Earth and Ocean Sciences at the University of Victoria. His principal area of research has been the study of crustal deformation within active seismic areas on the west coast of Canada using geodetic techniques such as leveling, precise gravity, laser-ranging trilateration, and GPS. Under his direction, the Geological Survey of Canada established the Western Canada Deformation Array, the first continuous GPS network in Canada for the express purpose of monitoring crustal motions. Data from this network provided the key information which led to the discovery of slow earthquakes and “Episodic Tremor and Slip” in the Cascadia Subduction Zone. Dr. Dragert led Canadian involvement in the Plate Boundary Observatory under the EarthScope Program, which has resulted in more intensive crustal deformation monitoring along the Cascadia Subduction Zone. He served on the UNAVCO Board of Directors from 2003–2006 and he was the Canadian Geophysical Union’s J. Tuzo Wilson medalist for 2007. Dr. Dragert received his B.Sc. in mathematics and physics from the University of Toronto and his M.Sc. and Ph.D. degrees in geophysics from the University of British Columbia.
