Professor Srinivas Bettadpur is one of a handful of individuals who helped invent a new method for measuring temporal changes in Earth’s gravitational field, resulting in the Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow-On satelli...

Earth science is a data-driven field, and Roger Bilham has brought tremendous energy and creativity to the measurement of data to quantify crustal deformation. For decades Roger has led projects to collect geophysical data in far-flung corners of the...

Kristine Larson was awarded the 2020 Charles A. Whitten Medal at the AGU Fall Meeting Honors Ceremony. The medal is for “her innovative applications of GPS geodesy to problems in environmental sensing, water cycle, geodetic seismology, and crustal dy...

David Sandwell is the preeminent leader in applying satellite altimetry data to determine the marine gravity field and seafloor topography to elucidate the thermal and mechanical behavior of the oceanic lithosphere. Through his deep knowledge of spac...

Veronique Dehant’s research area is the modeling of the deformable Earth’s interior in response to external forcing factors such as the gravitational attraction of the Sun and Moon and the rotational forces associated with the motion of i...

Paul Segall has contributed to observation, theory, and modeling of earthquake and volcanic processes inferred from surface geodetic measurements. Many practitioners in these fields, including past Whitten medalists, have had an impact on one of thes...

David Smith is a leader in satellite geodesy whose groundbreaking contributions have spanned tectonophysics, geodynamics, and planetary science. Born and educated in Great Britain, he joined NASA’s Goddard Space Flight Center in his early caree...

It is a pleasure and an honor to nominate W. Richard (Dick) Peltier for the AGU Charles A. Whitten Medal, which is awarded for outstanding achievement in research on the form and dynamics of the Earth. Dick is an eminent research scholar who has had,...
