Pacific seabed mining site still scarred 44 years on

Scientists returned in 2025 to a patch of the Pacific seabed that was mined in a test experiment 44 years earlier and found the area has still not recovered. Tracks and disturbances from the original test remain visible on the ocean floor, showing that damage from deep-sea mining can persist for decades. The findings add to ongoing debate over whether commercial deep-sea mining should be allowed to proceed.
Why now: The long recovery time at the test site fuels current debate over plans to expand deep-sea mining.
