We have a portable Time-Domain Electromagnetic (TDEM) system available which uses a transmitter coil to induce electric and magnetic fields into the subsurface and a receiver coil to measure the subsequent decay of these transients. Changes in the electrical and magnetic properties of the ground can be measured from these decay responses and modelled with appropriate software (supplied). Our system is suitable for a maximum exploration depth of around 150m when used with the supplied transmitter and loops.
Equipment available for loan
We have one Geonics PROTEM TDEM system available for loan.
Our TDEM system is used for:-
- Correcting the static shift of long-period MT systems - View a report by Prof Kathy Whaler
- Detection of water tables
- Fault mapping
