SuperSting Marine System


On lake

AGI has developed a new marine option of the famous SuperSting R8. The system comprises the SuperSting Marine, the Marine Log Manager software and an electrode towing cable.

The SuperSting Marine continuously records and stores data from a GPS receiver. Current is injected every 3 seconds and 8 apparent resistivity values representing 8 depth levels are read for each current injection. Depth of penetration depends on length of the cable and array type. Typically you will see down to aproximately 20% of the electrode spread length.
The Marine Log Manager software allows you to edit the recorded data, plot the boat track and the resistivity data on an imported map image and to format the data for the EarthImager 2D inversion software. Electrode positions can also be converted to UTM coordinates.
The electrode cable features graphite electrodes (US Patent 6,674,286), a kevlar strength member and water block. The advantage of the graphite electrodes is that they do not corrode as currrent is passed through them. Regular metal electrodes quickly corrodes in water environment due to electrolysis processes. The water block prevents water from entering the cable in case of a cut in the outer jacket.

SuperSting Remote Monitoring System

SuperSting Remote
Remote control of an electrical resistivity monitoring site is now possible by using the SuperSting Remote Monitoring System (SSRMS). The SSRMS can be controlled from a computer anywhere in the world by using the Internet, provided that there is an Internet connection at the monitoring site. The measurement tasks are set up in advance from the home office computer and the survey will be performed at the scheduled time. Email with information of measurement start, error and finish will be automatically sent to specified addresses. The “finish” email will have the measurement result file attached with the mail. The SSRMS also has a battery bank management system which makes sure that there is power available for each survey.
The system is used whenever there is a need to repeat measurement on a fixed installation of electrodes. Typical applications are monitoring leakage from landfills, monitoring of remediation progress at clean-up sites, monitoring progress of injected salt solution in hydrogeological tests, monitoring of sink hole activity in sensitive areas as under highways and apartment buildings, monitoring the moisture front progress after rain/irrigation, monitoring of permafrost annual development, monitoring fresh water/salt water interface in tidal areas, and much more.

EarthImager 3D

EarthInager 3D

The EarthImager 3D is our 3D resistivity imaging inversion software.
Our EarthImager 3D resistivity and IP inversion software inverts resistivity and IP data acquired with electrodes arranged in boreholes and/or on the surface and presents a 3D volume of inverted resistivity data with advanced volume rendering technique. The final resistivity or IP image-volume can be rotated in any orientation, zoomed in and out, and translated to anywhere inside the image window in order to see the volume of interest in detail. Colors representing areas of less interest can be made transparent so that the shape of a pollution plume, for example, can be visible. With EarthImager, 3D resistivity inversion can be as easy as two steps: Read Data and Start Inversion with only a few mouse clicks.

AGI Resistivity Imaging Cable Systems

AGI produces cable systems for all of the resistivity imaging instruments (SuperSting R8/IP, SuperSting R1/IP, MiniSting and the older Sting R1 and Sting R1/IP).
Cable types
The cable systems are manufactured in two types, the distributed electrode switch type and the central switching box type. Both can be used separately or in combination.
The advantage of the switch box type is that a more light weight and less expensive multi-channel cable can be used. The dual-mode switch is however only available in the distributed switch cables. For imaging projects where the survey conditions are favourable and production speed is imporant we recommend using the switch box cable system with the lightweight and less expensive cables.
Switch types
There are two types of switches used, the single channel switch originally designed for the Sting R1 instrument and the multi-channel switch designed for SuperSting R8/IP. Both types can be used by the SuperSting instruments, but the MiniSting and older Sting instruments can only use the single-channel switches.
Note that when Sting R1 cables are used with the SuperSting R8/IP the instrument will only record data in single channel mode.
The distributed cable switches come with the dual mode operation possibility, which is currently not available in the switch box version. The dual mode operation makes it simpler to obtain high quality readings in conditions where electrode polarization is a problem.

SwichBox Switch boxes
Switch box systems are used to control electrode connections via passive cables. Such cables can be made considerably more light-weight and can be used in many common survey situations.
New Dual Mode Cable Swift Dual Mode Automatic Electrode Cable
The dual mode electrode (US Patent 6,404,203) allows the user to measure IP using non-polarizable electrodes in an automatic electrode system and at the same time use stainless steel electrodes for current transmission. By using non-polarizable electrodes, a much better signal can be recorded, free from the polarization noise of a stainless steel electrode. You will not find this feature on any other resistivity/IP system!
We have designed the Dual Mode Electrode system to be easy to operate in the field. One single setting in the SuperSting allows you to select whether to perform a survey with only stainless steel electrodes or with the combination dual mode stainless steel/non-polarizable electrodes. Therefore, it is not necessary to always use non-polarizable electrodes if the survey specification does not call for it.
The Swift dual mode automatic electrode cable is backwards compatible with the Sting R1 and the old Swift system. We will gradually phase out the old type Swift electrode cable and completely replace it with the new Swift Dual Mode Electrode cable.

AGI information

Advanced Geosciences, Inc. (AGI) with headquarters in Austin, Texas, specializes in manufacturing and development of high-resolution geophysical instruments for resistivity and IP imaging. AGI manufactures the SuperSting R8/IP, SuperSting R1/IP and MiniSting earth resistivity imaging systems and the EarthImager 2D and 3D inversion software for processing of the recorded data.
Typical applications for the AGI systems include:

  • Geotechnical investigations
  • Construction site investigations
  • Borehole to borehole and borehole to surface tomography imaging
  • Fracture and cavity detection in bedrock
  • Groundwater exploration
  • Environmental investigation (i.e., mapping of pollution plumes, etc.)
  • Investigation of dam leakage
  • Sand and gravel exploration
  • Site characterization for development
  • Site investigation for horizontal drilling
  • Site investigation for tunneling operation
  • Marine image profiling using our unique SuperSting Marine system
  • Archeological studies.

The DC resistivity imaging method is especially valuable in areas where ground penetrating radar (GPR) and EM methods do not work because of conductive overburden. Conductive materials, for example clay, attenuates the radar (EM) signal so that no result, or very limited result, can be achieved. In such areas, which are very common in large areas of the world, the resistivity method is the only real alternative for subsurface 2D and 3D mapping of the near surface.

Field procedure is simple. First set out electrode stakes at even intervals. Then lay out the electrode cable and attach each take-out to the stakes. Finally connect the AGI instrument (any of the above listed ones) to the electrode cable, perform an automatic test to check that everything is connected correctly and then start the automatic recording. The resistivity measurements are stored directly in the memory of the instrument. When the field measurement is complete the data are downloaded to a PC computer, inverted from apparent resistivity into "true" resistivity and presented as a color cross-section of the subsurface.

Being an instrument manufacturer and not wanting to compete with our customers, AGI does not perform electrical resistivity surveys. Therefore, the examples and case histories on this web site is recorded and produced by our clients, whom we now thank for their valued contribution.
