Among the discoveries is a ghost octopus nicknamed "Casper." It's known that the ocean stores more carbon than the Earth's atmosphere, plants and soil, and scientists are still finding new species during rare exploration trips, with sample studies taking months or even years, Amon said. Less than 1% of the world's deep ocean waters have been explored, an endeavor that experts say is expensive, technical and time-consuming. "You can't regulate what you don't understand," said Duncan Currie, an international and environmental lawyer and legal adviser to the Deep Sea Conservation Coalition, a Netherlands-based alliance of environmental groups. Several major companies have pledged not to use metals extracted from the deep sea and nations including New Zealand, Fiji and Samoa have called for a moratorium until more is known about its potential impact, a move cheered by scientists and legal experts. "We are still very concerned about the consequences," said Elza Moreira Marcelino de Castro, Brazil's representative at the conference that began Monday.įrench President Emmanuel Macron said earlier this year that he supports a ban on deep sea mining, while on Wednesday, Germany, which has two exploration contracts, announced it would not sponsor such mining until further notice. The push has worried countries ranging from Germany to Costa Rica that are seeking to strengthen proposed regulations in the next two weeks. Nauru, a tiny island northeast of Australia, is leading the push to allow for actual mining, arguing that it's at high risk of climate change and seeks to financially benefit from the mining of metals sought in part for green technology like electric car batteries. "Emissions intensity of cobalt, aluminum and nickel mining and processing is high, so skyrocketing demand may result in rising net carbon footprints," it stated. The International Energy Agency has estimated a sixfold increase in demand for minerals by 2050 given that electric vehicles and renewable generation are so dependent on them, according to a Fitch Ratings report issued in early October. Convention on the Law of the Sea and agree to sponsor private companies that seek to explore international waters for copper, nickel, cobalt, iron, manganese and other minerals. The International Seabed Authority issues licenses to state-owned businesses and countries that subscribe to the U.N. "We will not have collapsed tailings dams, destruction of cultural sites, clearing of rainforest, child artisanal miners, to name a few recent ones," UK Seabed Resources said in a statement, referring to some of the impacts from mining on land. to explore the Clarion-Clipperton zone under two contracts. Mining companies argue that harvesting minerals from the sea bed instead of land is cheaper and has less of an impact, avoiding a "host of environmental and social issues," according to UK Seabed Resources, a subsidiary Lockheed Martin Corp. The push for deep sea mining has grown to the point that the authority is now meeting three times a year instead of two, with a key decision expected as early as July 2023. At least 17 of 31 licenses have been issued for this zone, with exploration occurring at depths ranging from 13,000 to 19,000 feet (4,000 to 6,000 meters). The first exploration license was issued in the early 2000s, with most of the the current exploratory activity is concentrated in the Clarion-Clipperton Fracture Zone, which covers 1.7 million square miles (4.5 million square kilometers) between Hawaii and Mexico. There's a lot that stands to be lost," said Diva Amon, a marine biologist, National Geographic explorer and a scientific adviser to the Benioff Ocean Initiative at the University of California, Santa Barbara. "It's one of the most pristine parts of our planet. It has issued 31 exploration licenses so far, and many worry the world's first license to go the next step and mine international waters could soon be approved with no regulations currently in place.Įxperts say mining could spark a rush to collect minerals that take millions of years to form and unleash noise, light and smothering dust storms deep in the Earth's oceans. The organization is the global custodian for deep ocean waters that don't fall within any country's jurisdiction. The issue will be in spotlight this week as dozens of scientists, lawyers and government officials gather in Jamaica to debate deep sea mining as part of a two-week conference organized by the International Seabed Authority, an independent body created by a United Nations treaty.
