The rush to mine lithium, cobalt, and nickel from deep-sea ecosystems for renewable energy technologies is challenging the status-quo, as scientists warn of environmental effect of deep-sea mining, and the costs of ocean floor extraction outweighing its clean energy efficacy.
Focus has centered on the Pacific’s minerals-rich Clarion-Clipperton Zone, where remote-operated vehicles scrape metal nodules from the seabed, creating sediment plumes that may smother marine life for hundreds of miles.
Even if these metals have technological benefits, like power the electric vehicles (EV) industry, and wind turbines, new research revealed that deep-sea mining is disrupting carbon-storing ecosystems.
All this will inevitably endanger species before their ecological roles are fully understood and fulfilled.
As deep sea mining technology develops, its risk to marine life is forming a clash between nature and technology.
Deep-Sea Mining Is Close to Reality Despite Environmental Concerns
Interest in deep-sea mining has soared due to increased demand for key resources. The deep sea mining Pacific Ocean, specifically the Clarion-Clipperton Zone, is an interest due to its high mineral density.
Mining is usually conducted with remotely operated vehicles (ROVs), which pick matter from the ocean floor, but the waste produced, sediment plumes, raises the question around environmental effects of deep-sea mining.
Despite the fears of deep sea mining effects on marine life, countries and companies are willing to exploit the mineral resources of the ocean. However, scientists are extremely worried about the environmental effects and the irreversible damage that it will impose on fragile marine ecosystems.
How Does Deep Dea Mining Affect the Ocean?
When looking at the environmental effects of deep-sea mining, we see how it affects the seafloor, which is dangerous for marine ecosystems and can lead to long-term ecological damage. Sediment plumes created by mining can suffocate marine life, and light and noise pollution can interfere with animals that communicate through sound, like whales.
Mining waste can spread over large areas, threatening species vital to global fisheries.
In response, organizations like Greenpeace have launched a deep-sea mining petition calling for a ban on the practice. Some countries, including Germany and Portugal, have already introduced laws to ban deep-sea mining in their waters, however, a global regulation is still missing.
MBARI’s Deep-Sea Mining Advancements
The technology behind deep-sea exploration has evolved rapidly, with organizations like MBARI taking the lead. Since 1990, MBARI’s ROV Ventana has explored Monterey Bay’s Ocean floor, contributing to new discoveries, such as bioluminescent jellyfish. The institute’s fleet of robots has helped uncover hidden marine life, track methane seeps, and study environmental impacts.
In 2025, MBARI launched the MOLA AUV, a small robot that comes fitted with sophisticated sensors and high-definition cameras. This new device can harvest crucial information about ocean ecosystems and is therefore critical in detecting the environmental effects of deep-sea mining on marine life. These technologies assist in following deep-sea mining impacts on marine life, ensuring that mining operations are well understood prior to their large-scale adoption.
Mining the Abyss for Green Tech’s Dirty Secret
The purpose of deep-sea mining is clear, a secure stream of minerals to fuel green tech, however, the risks to marine ecosystems are significant. With deep-sea mining looming on the horizon, the world must balance demands for resources with protecting marine life. Developments from MBARI are key to ensuring that these new technologies don’t come at the expense of the world’s fragile ecosystems.
But at what expense? The issue remains whether ocean depths can be responsibly mined or if the environmental effects of deep-sea mining will forever destroy marine life. As technology develops, so must regulations so that the oceans’ future and the minerals are secured.
