Abstract—An integrated approach involving Electrical Resistivity Tomography (ERT), Vertical Electrical Sounding (VES), and Very Low FrequencyElectromagnetic (VLF-EM) methods has been used to map the concentration and pathway of leachates plumes beneath Laka dump site in OgbomosoSouthwestern Nigeria. In-situ analysis, specifically, Electrical Conductivity (EC) and Total Dissolved Solids (TDS) were also carried out on water samplescollected from hand dug wells, bore holes and stream around th...
ABSTRACTThis study is aimed at using the characteristics of polluted soil to delineate different soillayers and deduce ways of providing remediation to the problems generated as aresult of soil pollution using Electrical Resistivity Method.An inversion of the measured apparent resistivity values using a computer program was carriedout to determine the true subsurface resistivity. This method was used toestimate the lateral and vertical extend to which a particular soil has beencontaminated by...
Time lapse seismic which geophysicists often abbreviate to four dimensional (4-D) seismic is a geophysical technique which involves simply repeating a series of 3-D seismic survey over time such that the fourth dimension is in “Calendar Time”. This gives it the ability to image fluid flow in a well volume.
line-height:107%;font-family:" verdana",sans-serif"="">Fibre optic technologies came out of military and space research and development programme. Until recently, glass chemistry and laser interrogation hardware have not been at a level of robust where systems could survive in down-hole environments for long periods. Because of the physical properties, glass can thrive as a sensor at extremely high temperatures and efficiently high temperatures and efficiently transmit large quantities of da...
line-height:115%">Forensic geophysics can be seen as that involving the use of geophysical methods in the search, locating and mapping of hidden or buried features underground or underwater. Geophysical methods have the potential to aid the search and recovery of a target because they can nondestructively and rapidly investigate large areas where a suspect, illegal burial or, in general, a forensic target or object is hidden in the subsurface.
Geophysical field school is an annual academic camping exercise that is aimed at exposing students to the practical aspects of geophysics. It is a three (3) credit hour course for third year students of applied geophysics aimed at educating students on the handling of geophysical equipment and the rudiments of data acquisition, processing and interpretation. line-height:107%;font-family:" tahoma",sans-serif"="">This year’s field school was held at Ikot Nakanda and i...

ABSTRACTThis study reviews earthquake monitoring and sensing in Nigeria. The techniques used to monitor earthquakes include seismic, Global position system (GPS) and remote sensingmethods. For now there is no scientific method of predicting earthquakes, butseismologists depend on the anomalous animal behaviour, radon emissions,trends, creep fault, drop/rise in the water level and anomalous plant behaviourfor earthquake prediction. The study also revealed that Nigeria is not seismicallyfree fr...
ABSTRACTThis research assesses the various factors responsible for road failures in thesouthwestern and south-southern parts of Nigeria with the aim of reportingfindings to the public domain. The research further stressed the importance andrelevance of geophysics in evaluating civil engineering structures such asroads. The above goals were met by studying the results of surveys carried outby researchers in southern Nigeria. Electrical Resistivity and Electromagneticmethods have been used to e...
ABSTRACTElectromagnetic waves generated by different wireless systems like mobile systems, satellite systems, microwave links…etc. facilitates our communications throughout the world. These waves have many effects on the human body as well as our daily lives. The effects of electromagnetic waves cause many problems and diseases in the human body like cancer. Nowadays, types of the cancer caused by these waves has increased, because mobile users have increased. Because of the importance of h...
The aim of this work is to describe various form and sources of electromagnetic radiation and its effect on earth.INTRODUCTIONElectromagnetic radiation (EM radiation or EMR) is a fundamental phenomenon of electromagnetism, behaving as waves and also as particles called photons which travel through space carrying radiant energy. In a vacuum, it propagates at the speed of light, normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave, it has both...
