Scientists have uncovered a staggering 332 hidden submarine canyons beneath Antarctica — some plunging over 4,000 meters deep. These colossal underwater valleys are more than just geological wonders. They're powerful forces that steer ocean currents, melt ice shelves from below, and potentially accelerate sea level rise.
East and West Antarctica reveal starkly different canyon systems — a clue to how ice sheets evolved and why they’re vulnerable today. Yet most climate models still ignore these local dynamics.
With only 27% of the ocean floor mapped in high resolution, this discovery is just the beginning. What else lies hidden beneath the ice?
Watch till the end to understand how these ancient canyons could shape our climate future.
