In 1979, a Deep-Sea Mining Experiment in the Pacific Altered the Seafloor—44 Years Later, Its Environmental Impact is Still Revealing Itself

44 years after a deep-sea mining experiment, the scars on the ocean floor are still visible. New research uncovers unexpected signs of life returning—but the full impact remains unclear.

In 1979, a deep-sea mining experiment in the Clarion-Clipperton Zone (CCZ) left a lasting mark on the seabed. Decades later, a groundbreaking study published in the journal Nature, co-led by the National Oceanography Centre and the Natural History Museum, London, provides new insights into the long-term ecological impacts of mining activities in the deep ocean.

In 1979, a Deep-Sea Mining Experiment in the Pacific Altered the Seafloor—44 Years Later, Its Environmental Impact is Still Revealing Itself

While the tracks carved by mining machines are still visible after 44 years, the environment is beginning to show signs of life returning to the area. However, questions remain about the extent of the damage and the recovery process.

A Window Into the Past: The Clarion-Clipperton ZoneThe Clarion-Clipperton Zone, located in the Pacific Ocean, has become a key target for deep-sea mining. Rich in manganese nodules, which are crucial for extracting battery metals like nickel and cobalt, the CCZ holds enormous potential for fueling the green energy transition.

However, mining the seafloor is fraught with unknowns, especially when it comes to the long-term ecological effects. The 1979 experiment, designed to study mining processes, serves as a valuable time capsule, offering a glimpse into the future of deep-sea mining and its potential environmental consequences.

FWIW, TMC is losing money and is not expected to breakeven until 2028. On the other hand, revenues are growing at a CAGR of 60%.
