This is a collection of various cases where the 2D resistivity imaging method pioneered by Advanced Geosciences Inc have been successfully applied. Click on a section below and you will be shown a full 2D resistivity imaging brochure detailing the case in question.


These cases have been submitted by satisfied customers whom we thank for permission to publish their data on the web. Each detailed brochure will have a citation for the source of the data.


Canal bottom investigation with towed electrodes
The SuperSting R8 Marine has been used to collect data from an electrode array towed behind a boat. The task was to detrmine the limestone quality and porosity below a seafront canal system in Florida.


Lake resistivity survey using towed electrodes.
A marine version of the SuperSting has been used to collect data from an electrode array towed behind a boat. The SuperSting collects and stores data from 8 depth levels for each current injection. The current injection cycle is 3 seconds. The SuperSting is connected to a GPS and continuously records the position of the boat during the survey.


Marine bottom resistivity survey.
The bottom layering in a Florida strait was investigated using resistivity imaging prior to construction of a utility tunnel.

The geophysical instruments used in the resistivity imaging cases described here are the AGI SuperSting R8/IP earth resistivity meter and the AGI Sting R1 earth resistivity meter together with the AGI Swift multi electrode cables and smart switches.
These make up systems with extremely fast data acquisition in the field. Today the single-channel Sting R1 has been replaced by the even faster and more accurate instrument: SuperSting R8/IP
The interpretation of data like this can be done using the 2D inversion program AGI EarthImager 2D available from AGI
