Robert E. Sheriff (19 April 1922 – 19 November 2014) was an American geophysicist best known for writing the comprehensive geophysical reference, Encyclopedic Dictionary of Exploration Geophysics. His main research interests included the seismic detailing of reservoirs , in 3-D seismic interpretation and seismic stratigraphy , and practical ...
In geophysics and physical geodesy, a geopotential model is the theoretical analysis of measuring and calculating the effects of Earth's gravitational field (the geopotential). The Earth is not exactly spherical, mainly because of its rotation around the polar axis that makes its shape slightly oblate.
James Freeman Gilbert (American, 1931–2014) – development of geophysical inverse theory; network of seismometers to study Earth's free oscillation; William Gilbert (English, 1544–1603) – early magnetic experiments; first to argue that the Earth itself is magnetic
Was there ever a collision of the Earth with another planet Theia, giving birth to the Moon? [1] There is compelling evidence, such as measures of a shorter duration of the Earth's rotation and lunar month in the past, pointing to a Moon much closer to Earth during the early stages of the Solar System.
is the free-air gravity anomaly. δ g B {\displaystyle \delta g_{B}} is the Bouguer correction which allows for the gravitational attraction of rocks between the measurement point and sea level; δ g T {\displaystyle \delta g_{T}} is a terrain correction which allows for deviations of the surface from an infinite horizontal plane
Thomas Telford FRS FRSE (9 August 1757 – 2 September 1834) was a Scottish civil engineer. After establishing himself as an engineer of road and canal projects in Shropshire, he designed numerous infrastructure projects in his native Scotland, as well as harbours and tunnels.
In geophysics and reflection seismology, the Zoeppritz equations are a set of equations that describe the partitioning of seismic wave energy at an interface, due to mode conversion. They are named after their author, the German geophysicist Karl Bernhard Zoeppritz, who died before they were published in 1919. [1]
In 1898, a Geophysical Institute was founded at the University of Göttingen, and Emil Wiechert became the world's first Chair of Geophysics. [3] An international framework for geophysics was provided by the founding of the International Union of Geodesy and Geophysics in 1919.
