BASE GEOPHYSICS

Geophysics is simply the study of the Earth by applying physics principles. Geophysics is the field of geoscience (Earth science) that in one way or another is related with other multidisciplinary natural and planetary science subjects such as environmental science, astronomy, Biology, geography, chemistry. This post will  describe the career path regarding geophysics, as there are interesting things you may want to hear. I hope we will be together until the end of this conversation. Become a Geophysicist Sometimes it gets overwhelming when it comes to know how you can become a geophysicist. To become a profession geophysicist you have to pursue a career in geophysics at least at undergraduate level, Bachelor's degree. You should have atleast higher education undergraduate majors degree in geophysics, geology, geoscience, physics. Also if you have multiple degrees in geophysics and geology is also a good way too, it will reach you where you want to go. This is an entry level qualif...

The first seismographs were built in the late 19th century were a mechanical synthesis of sorts - a seismometer rigged up to transfer its motions to some kind of timekeeping and recording device. Records, which became known as seismograms , were made continuously, by a pen tracing ink lines on paper, or a stylus etching smoked paper, with time "ticks" marked periodically to provide temporal reference points. See figure (3 and 4). What is a Seismograph? Seismograph Is the sensor device used to amplify and detect ground vibrations. Sometimes the word Seismometer is used to infer the same device. Seismographs basically consist of two (2) parts which are, 1. A seismometer: This is a sensor of ground motion 2. A seismic recording system. Basic Working Principle How does a seismograph work? Principle used by the seismometers, is that It works by " Inertia principle" . The most common is by using a mass suspended by a spring. This mass follows the motion of the ground...

DEPTH OF REFRACTOR As one of the primary objective of many seismic refraction surveys is to determine the depth of layers (refractor) from the ground surface. There are many softwares and techniques you can utilize to solve this problem on hand. But as a rule of thumb it is important to have a basic skill and knowledge on how to do things rather than blindly relied on softwares , that is why I hope this tutorial will help you to find the depth of layers from the surface by using simple time-distance (t-x) plot. However you should not quote me wrong that softwares are nothing in geophysics, No? That was not the intention, softwares finds their own vitality in geophysical processing and science in general! Okay! Let's be together until the end of this tutorial, How can you find the depth of refractor by time (t) - distance (x) plot? We have given the seismic refraction data as shown in figure 1, our task is to achieve the primary objective as stated above by using spreadsheet. I u...
