[00:00:00]This marsh [music] hides a sensor that listens to gases humans can't detect, so it's exposing something almost no one sees happening under our feet.

[00:00:10]Scientists use hyperspectral imaging rigs on low-altitude drones, which means they can capture invisible methane signatures leaking from wetlands in real time. But the wild part is how each wavelength pattern acts like a fingerprint, so the system maps tiny hotspots before the gas ever reaches the air. And that's why this tech is rewriting how we track [music] climate emissions, because it turns a silent swamp into a live, glowing warning system.
