Will ground penetrating radar work in saline bodies if put directly on the seafloor?
Our take
Ground penetrating radar (GPR) is primarily effective in fresh water, where its electromagnetic waves can penetrate the ground effectively. However, when it comes to saline bodies, the increased conductivity of saltwater can hinder GPR performance, limiting its ability to produce clear subsurface images. Dragging a GPR sensor directly on the seafloor may introduce additional challenges, such as interference from sediment and water layers. To determine its feasibility, careful consideration of the specific environmental conditions and intended objectives is essential for achieving reliable results.
We’re debating this at work right now. I know GPR works fine in fresh water but doesn’t usually work in saline water. If you could drag the GPR sensor on the sea floor would it work then? Thanks!
