What Does a Geophysicist Do?

Geophysics is one of the main disciplines of the earth sciences. It is based on quantitative physical methods (such as seismic elastic waves, gravity, geomagnetism, geoelectricity, geothermal, and radioactive energy) to study the earth and find mineral resources inside the earth. A comprehensive discipline covering the earth's crust, mantle, core and atmosphere ^[1] . There are many branches of geophysics, including: solid geophysics, geodynamics, seismology, geodesy, geothermal, geomagnetism, hydrogeography, oceanography, meteorology, geonuclear tectonics, exploration geophysics Science, comparative planetary science, geotectonic physics, and geoastronomy; the research contents include the internal structure of the earth, the theory of earthquake sources, the theory of seismic wave propagation, and large-scale features of the continental crust, such as plate subduction zones and mid-ocean ridges. Traditional geophysics mainly refers to solid geophysics, and modern geophysics research extends to phenomena outside the earth s atmosphere, such as ionospheric dynamo, auroral electrojets, and magnetopause current systems. system) and even the physical properties of other planets and their satellites. ^[2]

Geophysics

Geophysics uses the principles and methods of physics to observe the distribution and changes of various physical fields on the earth,

Generally speaking, geophysics is the use of physical methods to study the earth or other

Emil Wiechert is the world's first professor of geophysics.

While reading classic papers on geophysics, tracking the life of the authors who wrote these classic papers, including their childhood, and their academic genealogy before and after, is sometimes a very interesting and thought-provoking thing.

Most people say to seismologists

In developed countries such as the United States, Europe, and Japan, well-known international journals in the field of geophysics

From February 9th to 13th, 2016, China's 32nd Antarctic expedition team's ocean expedition team performed geophysical operations in the Victorian Basin of the Antarctic Ross Sea, and successfully collected the gravity, magnetic force, and reflected earthquakes of the 720 km survey line. data. This is the largest geophysical survey in China in recent years in the Ross Sea region, and it will provide solid data for Chinese scientists to study the history and process of the development of the Antarctic Rift Valley.

"The geophysical data collected this time will provide us with solid data for revealing the Ross Sea Victoria Basin and its relationship with the Southwest Antarctic Rift, as well as the historical activity range of the Ross Sea Glacier. This survey line connects China Existing geophysical data in the Victoria Basin and deep sea drilling plans for the Ross Sea drilling will also provide accurate stratigraphic age scales for interpretation of historical data.
