Researchers have developed an airborne imaging approach that detects unexploded munitions in shallow coastal waters with high confidence. The system combines advanced multispectral sensing with artificial intelligence to identify hazards that remain a threat to public safety, marine ecosystems, and infrastructure.
These underwater weapons, often left from past conflicts or training exercises, pose ongoing risks worldwide. They can be triggered by human activity or natural disturbances, and their corrosion may leak toxic compounds into the environment. Current detection methods are slow, costly, or ineffective in murky conditions.
The new technique can spot munitions even when they are partially hidden by sediment, biological growth, or debris. This improves on traditional sonar or visual surveys, which struggle with camouflage and clutter in shallow, dynamic waters. The system offers a faster, wider-area scanning capability.
If deployed operationally, it could accelerate clearance operations and reduce risks to divers and coastal communities. Port authorities and environmental agencies may benefit from safer, more frequent surveys. The approach also holds potential for mapping other seafloor hazards like lost fishing gear or pipelines.
While the results are promising, the technology has only been tested in controlled conditions. Real-world performance in variable weather, wave states, and diverse seafloor types remains to be validated through broader trials.
