Tonie van Dam

Tonie Marie van Dam (born April 19, 1960) is an American geophysicist and geodesist, known for her pioneering research on solid Earth deformations due to loads from atmospheric and hydrologic pressures. She and her collaborators used space geodetic observations and modeling for increased precision in measuring and understanding such loads.

Biography Tonie van Dam graduated in 1982 with a B.S. in physics and geology from Mary Washington College (now renamed the University of Mary Washington). At the University of Colorado Boulder, she graduated in 1991 with a Ph.D. in geophysics. Her Ph.D. thesis Atmospheric Load Response of the Solid Earth and Oceans was supervised by John M. Wahr. Her research focuses on the geodesy and geophysics of loads from atmospheric and hydrologic pressures. Her 2001 article Crustal displacements due to continental water loading (written with six collaborators, including John M. Wahr, Geoffrey Blewitt, and Kristine M. Larson) is considered a classic in geodesy. Van Dam has served the community of geophysicists and geodesist in several capacities and since 2019 is a member of the board of directors of UNAVCO. She is an associate editor for the Institute of Geophysics of the Czech Academy of Sciences's Studia Geophysica et Geodaetica from 2010 to the present and for the International Association of Geodesy's Journal of Geodesy from 2015 to the present. and in 2020 elected her a Fellow of the AGU. She received in 2019 the European Geosciences Union's Vening Meinesz Medal.
