This drone reveals what lies beneath snow and soil

Phys · · 609 words · By Stein Mortensholm

Researchers at SINTEF are developing drones equipped with advanced sensors, such as ground-penetrating radar and magnetometers, to analyze subsurface conditions. These tools are being used to assess avalanche risks, forecast spring floods, and detect soil contamination or war remnants in challenging environments.
