Measuring Geological Features and Structures with Geophysical Equipment
Geonics Instruments’ geophysical equipment has a wide variety of uses in measuring geological features and structures. Not only are they capable of detecting underground water, but also of providing insights into the composition and structure of underlying rock, soil and sediment layers. The instruments offer detailed readings. Interpretations help identify subsurface faults and fractures, as well as distinguish between different types of soils. In some cases, they can detect even the smallest changes in the subsurface. By monitoring over a long period of time one may observe the migration of contaminates. This makes them invaluable for locating preferential paths for fluids to flow. With these instruments, it is possible to detect objects that would otherwise be too small to locate by drilling. For example, the time and money necessary for closely spaced boreholes to find a karst feature can take up valuable resources while still providing no guarantee of success.
Detecting Buried Metal Objects with the Right Tools
Geonics Instruments’ geophysical equipment does more than just measure geological features and structures. Their advanced technology uses electromagnetic (EM) emissions to measure variations in electromagnetic responses over large areas. They can also detect buried metal objects, such as pipelines, cables, utility lines, underground storage tanks (UST), and even municipal fill. With the help of Geonics Instruments’ geophysical equipment, engineers can detect these objects. Often with relatively high precision and accuracy in a short amount of time. Unlike drilling randomly placed boreholes to explore a site, you can significantly reduce the risk of running into costly unexpected buried objects using geophysical instruments. For example, the time and money necessary for closely spaced boreholes to find an underground storage tank or UST can take up valuable resources while still providing no guarantee of success.
When the EM response is detected by the instrument, it is converted into a digital format. This format can then create 2-D plan view images. Plan view maps offer great detail on the location of buried metal objects or other zones of interest. In addition, their systems integrate GPS coordinates for relocating areas of concern, which further reduces field time for professionals. All these features make Geonics Instruments’ geophysical equipment invaluable for the reliable and efficient detection of buried metal objects.
Identifying Potential Hazards Near Construction Sites
Geonics Instruments’ geophysical equipment is an important tool for engineers working on construction projects. Instruments can provide information about the landscape and infrastructure around the site. Under the right conditions, the instruments can map underground anomalies caused by sinkholes, buried foundations, large storm drains, and unexpected construction or municipal fill. Measuring the size of an anomaly helps engineers assess potential hazards at a construction site. In addition, detection can reveal hidden dangers that may not be visible to the naked eye. With EM31, EM34, EM38, and EM61’s ability to acquire site-specific data about potential hazards promptly, Geonics Instruments help ensure that a project is completed with safety in mind.

Types of Geonics equipment
Geonics offers EM31, EM34, EM38, and EM61s. While the EM61 is a time-domain electromagnetic instrument or TDEM device designed specifically for metal detection, the other three units are electromagnetic terrain conductivity meters. These patented instruments measure apparent conductivity and are designed to scan large areas quickly and accurately.
Geonics EM31, EM34, and EM38 electromagnetic terrain conductivity meters
Ground conductivity meters are powerful tools for measuring subsurface conductivity and magnetic susceptibility. These meters do it without any need for direct contact between the instrument and the soil. The main advantage of this non-invasive method is its ability to quickly collect closely spaced data. Closely spaced data provides better spatial resolution over a range of geologic environments. This includes areas with materials with sand, gravel, and clay-rich soils. Furthermore, ground conductivity meters boast a robust design that can easily withstand harsh weather and environmental conditions while gathering reliable data in remote locations. As a result, they are often used by experts in several fields including geophysics, civil engineering, hydrology, archaeology, and mineral exploration.
Above all, their readings can be integrated with other datasets. Integrating GPR, magnetics, seismic, or electrical resistivity methods can provide meaningful insight in a study. Since these instruments have low power requirements they are very portable. Without doubt, they are easier to carry than many other geophysical instruments.
When comparing EM34, EM31, and EM38 instruments
the EM34 offers one of the greatest advantages in terms of depth penetration. With its two coils connected by a cable, it can be configured for depths of about 25ft, 50ft, 100ft, and 200ft. The EM38 instrument focuses on shallow conditions, up to approximately 5ft. In comparison to the EM34, the EM38 is better suited for conditions as shallow as 1 ½ft. Meanwhile, an EM31 and an EM31 short are optimized for depths between about 5 and 20ft. All four instruments measure the inphase response which can be useful for locating buried metal. To be sure, it’s important to note that they all function best when used within their specific depth range. The EM38 will not penetrate deeper than about 5ft. It is not suitable for greater depths. In constast, the EM34 is unlikely a good choice for depths less than 25 feet.
The EM38-4 and EM31-8 instruments
from Geonics are the latest developments in apparent conductivity measurement. The EM38-4 offers a range of shallow measurements, from 1.5ft to 5ft, utilizing four sets of coils for data collection. This advanced design is capable of covering vast areas with ease. Like the EM31-8, it can be used with a sled or cart for faster data acquisition.
The EM31-8 offers eight sets of coils that measure apparent conductivities between 5ft to 18ft. Such versatility allows scientists and engineers to acquire greater amounts of apparent conductivity data. Both new models are incredibly easy to set up and operate. This makes them ideal for any user regardless of their technical knowledge or experience level. Furthermore, their additional coils detect even more minute changes at varying depths which provides further insight into subsurface composition and structure. As such, these innovative instruments are sure to revolutionize how apparent conductivity is measured in the future.
