Instrumentation GDD Inc. is a world leader in high-tech geophysical instrumentation for mining and exploration geophysics, groundwater exploration, geotechnical investigations and other related fields. Since 1976, GDD has developed, manufactured and sold a wide range of Electromagnetic (EM) and Resistivity/Induced Polarization geophysical instruments.
Geotechnical geophysical investigations, in many instances, enhance the reliability and speed of geotechnical investigations, and reduce the cost of the investigation. However, ... Geophysical instruments are designed to map spatial variations in the physical properties of the Earth (Table 1). A gravimeter, for example, is designed to measure ...

Use of Geophysical Instruments in Near-Surface Investigations V1.0 4 sub-surface conditions may put the public at risk. In these instances, the scope of practice is restricted to geophysicists. Historical practice Certain geophysical instruments have historically been used in applications without the involvement of a geophysicist.
RI: Limited or moderate removal is required, often only in geophysical data collection area and intrusive investigation areas. RA: The most extensive removal is required in this phase to allow geophysical data collection coverage and intrusive investigations.
Geophysical Investigations with the Geonics EM61-MK2 and EM61 ... features must also be considered in the selection of instruments. c. Determine required data density, based on type of investigation: Size and depth of ... Size and depth of expected targets, and method used for detection will dictate minimum requirements for line and station ...
If it is not, then the geophysical model has to be rejected and a new one developed which does provide a reasonable geological solution. Applications . Hydrocarbon exploration (coal, gas, oil) Regional geological studies (over areas of 100s of km2 ) Exploration of mineral deposits. Engineering site investigation. Hydrogeological investigation .
The geophysical equipment for these types of investigations often include Geometrics' Geode, Ballard borehole source, GeoStuff triaxial geophones, 2 Hz or 4.5 Hz geophones for MASW, an accelerated weight drop like a 700 lb elastic wave generator, 4.5 to 40 Hz geophone for Seismic Reflection and Seismic Refraction, a 10 to 20 lb sledge hammer ...
Sep 19, 2013· • The geophysical instruments used in the field are simple, portable and can be operated easily. This means fieldwork is not laborious. • Since the work is carried out quickly and only physical observations are made. Without the use of consumables (like Chemicals), it is economical too. 5.

H. O'Brien, in Mineral Deposits of Finland, 2015. Pipe 17. Kylmälahti. Geophysical surveys included magnetic and electromagnetic profiles. 21 till samples were taken to investigate the heavy mineral content of the area but only picking results are available. 20 diamond drill holes were drilled to estimate the size and shape of the body. Kimberlitic material occurred in 12 drill holes.
1 Introduction. Geophysical measurements can reveal the interior properties of icy ocean worlds. Such measurements can point to the presence and temporal variability of fluids and gases, thus identifying potential habitable niches for life (Vance et al., 2017).The thickness and geodynamics of different ice phases, and the depth of the ocean, determine the conditions under which life might exist.

Geophysical methods for the investigation of a closed dumping ground Geophysical investigations cannot completely replace borehole investigations. The information obtained by intrusive methods is required to constrain and verify geophysical interpretations. But the latter can significantly reduce the number of required boreholes.
Geonics TDEM instruments are capable of greater depths of investigation than their FDEM instruments. The greater depths offered by the geophysical time domain instruments lends themselves to groundwater investigations, identifying structural geology, mapping contaminate plumes, and locating ore bodies.
EXI is pleased to act as the exclusive US reseller for select instruments from MOHO Science and Technology. EXI is the largest and best-known geophysical equipment rental company in North America specializing in near-surface applications. We carry over 81 different types of systems and hundreds of units in our inventory.
To sum it up, the electrical resistivity instruments are setup at the center of a resistivity line. The instruments include the main SuperSting R8 console, an 84-channel switch box, and one or two deep cycle 12VDC batteries. The SuperSting console, for most near surface geophysical applications, is both the transmitter and the receiver.
Geophysical tools are implemented in a wide range of applications ranging from building ground investigations to the inspection of dams and dikes (Soupios et al., 2007), targeting toward the ...
