Geophysics is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. Geophysicists, who usually study geophysics, physics, or one of the Earth sciences at the graduate level, complete investigations across a wide range of scientific disciplines. The term geophysics classically refers to solid earth applications: Earth's shape; its gravitational, magnetic fields, and electromagnetic fields ; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics; and analogous problems associated with the Moon and other planets.
The International Union of Geodesy and Geophysics is an international non-governmental organization dedicated to the scientific study of Earth and its space environment using geophysical and geodetic techniques.
GNSS reflectometry involves making measurements from the reflections from the Earth of navigation signals from Global Navigation Satellite Systems such as GPS. The idea of using reflected GNSS signals for earth observation was first proposed in 1993 by Martin-Neira. It was also investigated by researchers at NASA Langley Research Center and is also known as GPS reflectometry.

Fox was born in Devonport, Tasmania, Australia and resided in Troy, NY, United States until his death on 27 March 2021, at the age of 61.
Diane McKnight is a distinguished professor of civil, environmental, and architectural engineering at the University of Colorado Boulder and a fellow at the Institute of Arctic and Alpine Research (INSTAAR). McKnight is a founding principal investigator of the National Science Foundation's Long-Term Ecological Research (LTER) program in the McMurdo Dry Valleys of Antarctica.
Joan S. Gomberg is a research geophysicist at the United States Geological Survey. She serves as an adjunct professor at the University of Washington. She is interested in subduction zone science, and studies how earthquakes trigger each other and how faults can slip. Gomberg is a Fellow of the American Geophysical Union. She was the first person to demonstrate how dynamic stress associated with seismic waves can trigger other earthquakes.
Véronique Dehant is a Belgian geodesist and geophysicist. She specializes in modeling the deformation of the Earth's interior in response to the planet's rotation and the gravitational forces exerted upon it by the Sun and Moon. She has used similar techniques to study Mercury, Venus, Mars and the icy satellites of the outer planets. She primarily works at the Royal Observatory of Belgium, but also serves as an Extraordinary Professor at the Université Catholique de Louvain.
Éric Calais is a French geologist-geophysicist, born in 1964, internationally recognized practitioner of high-precision space geodesy and a pioneer in its applications to measure seismic deformations at the boundaries of tectonic plates and in their interiors. He has been a member of the French Academy of Sciences since 2017.
The Ann and H.J.
