Deep-sea mining causes huge decreases in sealife across wide region, says study

Scientists caution against rush to mine the seabed, and say it could be decades before the full impact on marine life is known

Animal populations appear to decrease where the deep sea is being mined, and the impact on marine life of the controversial industry may involve a wider “footprint” than previously expected.

According to analysis of seabed ecology undertaken after drilling tests in 2020 in Japan – the country’s first successful extraction of cobalt crusts from deep-sea mountains – there was a decrease in marine life such as fish and shrimp at the site a year later. The density had dropped even further in areas outside the impact zone, by more than half.

Ireland and Sweden join countries calling for moratorium on extraction of metals from seabed as UN-backed authority prepares for crucial talks

The list of countries calling for a pause on deep-sea mining continued to grow this week ahead of a key moment that mining companies hope will launch the fledgling industry, and its opponents hope could clip its wings, perhaps for good.

Ireland and Sweden became the latest developed economies to join critics, including scientists, environmental organisations and multinationals such as BMW, Volvo and Samsung. The carmakers have committed not to use minerals mined from the seabed in their electric vehicles.

Company rebuts claims by scientists that ‘uncontrolled and unscientific’ practices highlight dangers of going ahead with seabed mining

Video footage from a deep-sea mining test, showing sediment discharging into the ocean, has raised fresh questions about the largely untested nature of the industry, and the possible harms it could do to ecosystems as companies push to begin full-scale exploration of the ocean floor as early as this year.

The Metals Company (TMC), a Canadian mining firm that is one of the leading industry players, spent September to November of last year testing its underwater extraction vehicle in the Clarion Clipperton Fracture Zone, a section of the Pacific Ocean between Mexico and Hawaii.

Berlin urges International Seabed Authority to prioritise nature as it debates rules and warns seabed mining may ‘destroy ecosystems’

Germany has called for a pause in the controversial deep-sea mining industry, saying not enough is known about the likely impacts of digging up the ocean floor for metals.

While other nations, including Spain and New Zealand, have previously called for a temporary halt to any exploitation of deep-sea metals, Germany, the world’s fourth biggest economy, is the most significant nation to voice its opposition to date. The country holds two of the 22 licences for exploration of the seabed.

The ISA, obliged to frame industry rules by 2023, drops reporting service and is accused of lacking transparency in plans for mining
• Podcast: The race to mine the deep sea

The UN-affiliated organisation that oversees deep-sea mining, a controversial new industry, has been accused of failings of transparency after an independent body responsible for reporting on negotiations was kicked out.

The International Seabed Authority (ISA) is meeting this week at its council headquarters in Kingston, Jamaica, to develop regulations for the fledgling industry. But it emerged this week that Earth Negotiations Bulletin (ENB), a division of the International Institute for Sustainable Development (IISD), which has covered previous ISA negotiations, had not had its contract renewed.

Last week’s court decision affirmed the view that seabed mining is too dangerous, too risky and too harmful to the environment

The decision by New Zealand’s Supreme Court last week against a giant seabed mining proposal in the South Taranaki Bight is a wake-up call for the world’s would-be seabed mining industry, both in the deep oceans of international waters and for countries contemplating such activities off their own coasts.

The mining operation, proposed by Trans-Tasman Resources (TTR), would have dug up 50 million tonnes of the seabed every year for 35 years, targeting 5m tonnes of iron ore and dumping the remaining 45m tonnes back into the ocean.

To catch a shark in the waters off Papua New Guinea, first the men sing.

They sing the names of their ancestors and their respects to the shark. They shake a coconut rattle into the sea, luring the animals from the deep, and then catch them by hand.
