Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves. The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic
A major goal of USArray was to collect detailed seismic images of the North American lithosphere. The data collected from USArray was integrated with geologic observations made on the Earth's surface to help determine the geologic history of North America, as well as to better understand that geologic processes that are at work today.

To honor Karcher's contribution to the use of geophysical methods in oil exploration, the J. Clarence Karcher Award [10] is given in recognition of significant contributions to the science and technology of exploration geophysics. In 1976, Karcher received the Anthony Lucas Medal from the American Institute of Mining and Metallurgical and ...
Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods at the surface of the Earth, such as seismic, gravitational, magnetic, electrical and electromagnetic, to measure the physical properties of the subsurface, along with the anomalies in those properties.
The method attempted to locate the domes and anticlines that held oil deposits, by using a controlled explosion on the surface to beam sound waves into the earth. Strategically placed sensors then recorded the speed and frequency at which the waves were reflected back to the surface by subterranean layers of rock, with the goal of creating a ...
Poulter taught physics while attending high school (1914-1918), joined the U.S. Navy in 1918 and returned to school in 1921. Poulter received his B.S. from Iowa Wesleyan College (IWC) in 1923; took a position as head of the chemistry division at IWC (1925); and served as head of the math, physics and astronomy divisions with "great creativity and much success" while attending graduate school ...
Near-surface geophysics is the use of geophysical methods to investigate small-scale features in the shallow (tens of meters) subsurface. [1] It is closely related to applied geophysics or exploration geophysics. Methods used include seismic refraction and reflection, gravity, magnetic, electric, and
The need for migration has been understood since the beginnings of seismic exploration and the very first seismic reflection data from 1921 were migrated. [5] Computational migration algorithms have been around for many years but they have only entered wide usage in the past 20 years because they are extremely resource-intensive. Migration can ...
