Advantages of using Schlumberger Array over Wenner


                It requires less manpower and time than Wenner soundings.


                It is less sensitive to lateral variations in resistivity.


The potential electrodes are moved only occasionally; In a Wenner sounding the potential and the current electrodes are always moved after each measurement.


It is faster in field operation.


Types of VES Curves

Requires less physical movement of electrodes than the normal Wenner array because only the current electrodes must be moved between readings.


The effects of near surface, lateral inhomogeneities are less on Schlumberger measurements when compared to Wenner measurements.


In industrial areas, stray currents and telluric currents that are measured with long spreads have effect on measurements made with the Wenner array more than those made with the Schlumberger array.


 Advantages of Wenner array over Schlumberger Array


Easier to calculate the apparent resistivity.


Wider spacing of the potential electrodes results in larger potential differences.


Requires small current

Haystack rock of Cannon Beach, Oregon

credit: I just stumbled upon this rock called Haystack Rock located in the coast of Oregon. It is a popular icon and a tourist centre especially for movie makers. The sea-washed sand on Cannon Beach makes a mirror image of the 235-foot basalt monolith known as Haystack Rock. Further reading... It might interest you to know that at low tide, holes and crags in the stone’s base become tide pools, a primary habitat for numerous sea creatures. At the rock’s high tide level is the abode of the sea birds like bald eagle, tufted puffins, and pelagic cormorants. See Credit Here:

THE AGE OF THE EARTH - THE OLDEST MAN ON EARTH IS THE EARTH

THE AGE OF THE EARTH Hey … Just as we celebrate our birthdays to commemorate the day we were born, has it ever occurred to you to ponder on the age of the earth? Don’t you think that there was a day (way back) when the earth was formed? Don’t get it twisted!!! This is no myth. It is a reality. It is REAL!!! The Earth is approximately 4.6 billion years old!!! Sounds absurd??? Well, this figure did not come as a result of fiction or imagination – but by radiometric dating in the early 20 th century. Lead in uranium-rich minerals when dated by early scientists,  were able to discover that they were billions of years old. Another pointer to this is that small crystals of Zircon obtained from Jack Hills, Western Australia when dated, was around 4.4 billion years old. One may ask: “How is this possible”? Rocks are aggregate of minerals. Some of these minerals have radioactive elements like Uranium and Thorium. In the process of their decay (radioac...

GROUNDWATER POLLUTION (vis-à-vis Groundwater Quality) AND CAUSES

Groundwater in it’s natural state is made up of dissolved substances including gases. These contribute greatly to it’s quality. The surrounding environment (Formations), anthropological and bacterial activities influence it’s quality as well. Below is a rundown of factors that determine the quality of any groundwater: They can be categorised into: 1.    Physical factors; 2.    Bacterial factors; 3.    Chemical factors; 4.    Anthropological factors. Physical factors can be easily seen with the eyes without first being analysed in the laboratory. They are apparent to the physical senses of sight, smell, taste and in some cases, touch. It can be known physically if a groundwater is polluted or not by Colour changes, Odour, presence of suspended materials. The presence of suspended materials make the water appear cloudy. Commonsensically, no sane person will like to consume anything, let alone, water tha...
