What Are Echo Sounders? Integrating ERT, IP & VES for Subsurface Exploration
An echo sounder is a device used to measure the depth of water bodies and identify underwater objects by emitting sound waves and recording the echoes that return. Echo sounders are widely used in a variety of fields such as…
What is ert resistivity?
Electrical Resistivity Tomography (ERT) is a geophysical exploration technique that involves placing electrodes on the ground surface or in boreholes to inject electrical current into the subsurface and measuring the resulting voltage differences. This method allows for the imaging of…
