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
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.
European powers employed sailors and geographers to map and explore North America with the goal of economic, religious and military expansion. The combative and rapid nature of this exploration is the result of a series of countering actions by neighboring European nations to ensure no single country had garnered enough wealth and power from ...
There are many methods and types of instruments used in geophysical surveys. Technologies used for geophysical surveys include: [1] Seismic methods, such as reflection seismology, seismic refraction, and seismic tomography. This type of survey is carried out to discover the detailed structure of the rock formations beneath the surface of the Earth.
Seismology (/ s aɪ z ˈ m ɒ l ə dʒ i, s aɪ s-/; from Ancient Greek σεισμός (seismós) meaning "earthquake" and -λογία (-logía) meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies.
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 ...
Eugene McDermott (February 12, 1899 - August 23, 1973) [1] was an American engineer and geophysicist who co-founded Geophysical Service Incorporated (GSI) in 1930 and later its parent company Texas Instruments in 1951. [2]
The History of North America encompasses the past developments of people populating the continent of North America. While it was commonly accepted that the continent first became inhabited by humans when individuals migrated across the Bering Sea 40,000 to 17,000 years ago, [ 1 ] more recent discoveries may have pushed those estimates back at ...
