Patania One became in May 217the first robot in 40 years to be lowered to the sea floor in the Clarion Clipperton Zone (CCZ), about 5,000 metres beneath the Pacific ocean…There it gathered data about the seabed and how larger robots might move carefully across it, sucking up valuable minerals en route.
The CCZ is a 6m square-kilometre (2.3m square-mile) tract between two of the long, straight “fracture zones” which the stresses of plate tectonics have created in the crust beneath the Pacific. Scattered across it are trillions of fist-sized mineral nodules, each the result of tens of millions of years of slow agglomeration around a core of bone, shell or rock. Such nodules are quite common in the Pacific, but the CCZ is the only part of the basin where the International Seabed Authority (ISA), which regulates such matters beyond the Exclusive Economic Zones (EEZs) of individual countries, currently permits exploration. Companies from Japan, Russia, China and a couple of dozen other countries have been granted concessions to explore for minerals in the CCZ. The ISA is expected to approve the first actual mining in 2019 or 2020.
This could be big business. James Hein of the United States Geological Survey and colleagues estimated in a paper in 2012 that the CCZ holds more nickel, cobalt and manganese than all known terrestrial deposits of those metals put together. The World Bank expects the battery industry’s demand for these, and other, minerals to increase if the transition to clean energy speeds up enough to keep global temperatures below the limits set in the Paris agreement on climate.
One of the firms attracted by this vast potential market is DEME, a Belgian dredging company ….Korea, Japan and China all have state-run research projects looking to dredge nodules from the deep sea with robots: “It really is a race,” says Kris Van Nijen, who runs DEME’s deep-sea mining efforts…
[It was expected]that deep-sea mining would develop rapidly by the 1980s. A lack of demand (and thus investment), technological capacity and appropriate regulation kept that from happening. The UN Convention on the Law of the Sea (UNCLOS), which set up the ISA, was not signed until 1982. (America has still not ratified it, and thus cannot apply to the ISA for sea-floor-mining permits.)
Mr Van Nijen and his competitors think that now, at last, the time is right. DEME is currently building Patania Two, or P2… In order to satisfy the ISA, this new machine does not just have to show it can harvest nodules; it also has to show that it can do so in an environmentally sensitive way. Its harvesting will throw up plumes of silt which, in settling, could swamp the sea floor’s delicate ecosystem. A survey of CCZ life in 2016 found a surprising diversity of life. Of the 12 animal species collected, seven were new to science…
The CCZ is not the only sea floor that has found itself in miners’ sights. Nautilus, a Canadian firm, says it will soon start mining the seabed in Papua New Guinea’s EEZ for gold and copper, though at the time of writing the ship it had commissioned for the purpose sits unfinished in a Chinese yard. A Saudi Arabian firm called Manafai wants to mine the bed of the Red Sea, which is rich in metals from zinc to gold. There are projects to mine iron sands off the coast of New Zealand and manganese crusts off the coast of Japan. De Beers already mines a significant proportion of its diamonds from the sea floor off the coast of Namibia, although in just 150 metres of water this is far less of a technical challenge.
If the various precautions work out, the benefits of deep-sea mining might be felt above the water as well. Mining minerals on land can require clearing away forests and other ecosystems in order to gain access, and moving hundreds of millions of tonnes of rock to get down to the ores. Local and indigenous people have often come out poorly from the deals made between miners and governments. Deep-sea mining will probably produce lower grade ores, but it will do so without affecting human populations.

Most deforestation takes place in poor countries. In richer places, trees tend to multiply. Australia is an unhappy exception. Land clearance is rampant along its eastern coast, as farmers take advantage of lax laws to make room for cattle to feed Asia. WWF, a charity, now ranks Australia alongside Borneo and the Congo Basin as one of the world’s 11 worst “fronts” for deforestation.
The world’s vast oceans and seas offer seemingly endless spaces in which adversaries of the United States can maneuver undetected. The U.S. military deploys networks of manned and unmanned platforms and sensors to monitor adversary activity, but the scale of the task is daunting and hardware alone cannot meet every need in the dynamic marine environment. Sea life, however, offers a potential new advantage. Marine organisms are highly attuned to their surroundings—their survival depends on it—and a new program out of DARPA’s Biological Technologies Office aims to tap into [marine animals] natural sensing capabilities to detect and signal when activities of interest occur in strategic waters such as straits and littoral regions.
The oil spill that hit the Fujairah coast on January 25, 2018 was the result of tankers illegally cleaning out their holds. That is according to the general manager of Fujairah port (UAE), Capt Mousa Murad, who has called for 24-hour monitoring of ships to tackle the issue. “The recent oil spills have been caused by tank cleaning by passing ships,” Capt Murad told The National on Tuesday. “Especially when tankers change from [carrying] one product to another,” he said, implying that the spills are made up of residue cleaned from within the tanks. He said the oil “comes from international waters and could hit Dibba, Fujairah or Khor Fakkan.”…
Cesspools—holes in the ground where untreated human waste is deposited—have become a crisis in Hawaii, threatening the state’s drinking water, its coral reefs and the famous beaches that are the lifeblood of its tourist economy. Sewage from cesspools is seeping into some of Hawaii’s ocean waters, where it has been blamed for infections suffered by surfers and snorkelers. It is also entering the drinking water in part of the state, pushing nitrate levels close to the legal limit.
China on January 25, 2018 outlined its ambitions to extend President Xi Jinping’s signature Belt and Road Initiative to the Arctic by developing shipping lanes opened up by global warming. Releasing its first official Arctic policy white paper, China said it would encourage enterprises to build infrastructure and conduct commercial trial voyages, paving the way for Arctic shipping routes that would form a “Polar Silk Road”…China, despite being a non-Arctic state, is increasingly active in the polar region and became an observer member of the Arctic Council in 2013.
In the 1920s, when Ireland became independent, it was thought to have just 220,000 acres (90,000 hectares) of woods, covering about 1% of the land. Once-extensive forests had been shrinking for centuries…In 2017, though, almost 11% of Ireland is covered with forest, and an unknown additional amount by small woods and scattered trees. The government’s target is to cover 18% of the land area with forests by 2046. Ireland is behind schedule. Still, about 6,000 hectares of new forest ought to be planted this year, while almost none will be lost. It is part of a broad trend: the foresting of the West.
The Dead Sea is dying. Half a century ago its hyper-salty, super-pungent waters stretched 80km from north to south. That has shrunk to just 48km at its longest point. The water level is falling by more than a meter per year. All but a trickle from its source, the Jordan River, is now used up before it reaches the sea. “It will never disappear, because it has underground supplies, but it will be like a small pond in a very big hole,” says Munqeth Mehyar of EcoPeace, an NGO.
Daniel Stiles, a self-styled ape trafficking detective in Kenya, had been scouring Instagram, Facebook and WhatsApp for weeks, looking for pictures of gorillas, chimps or orangutans. He was hoping to chip away at an illicit global trade that has captured or killed tens of thousands of apes and pushed some endangered species to the brink of extinction.
Europe’s space agency is defending plans to launch two satellites that would drop a rocket stage likely to contain highly toxic fuel in some of the most ecologically sensitive waters of the Canadian Arctic…
South Carolina is suing the U.S. government to recover $100 million in fines it says the Department of Energy owes the state for failing to remove one metric ton of plutonium stored there. The lawsuit was filed on August 7, 2017.
U.S. District Judge Sue L. Robinson of Delaware on June 21,2017 sided with the federal government in blocking a $367 million merger between EnergySolutions and the radioactive site’s parent company. Waste Control Specialists calls the deal essential for its long-term viability.The details of Robinson’s opinion were sealed.
Since their invention in the 1960s, disposable plastic bags have made lives easier for lazy shoppers the world over. But once used, they become a blight. This is particularly true in poor countries without good systems for disposing of them. They are not only unsightly. Filled with rainwater, they are a boon for malaria-carrying mosquitoes. Dumped in the ocean, they kill fish. They may take hundreds of years to degrade. On March 15th Kenya announced that it will become the second country in Africa to ban them. It follows Rwanda, a country with a dictatorial obsession with cleanliness, which outlawed them in 2008…
Several options are available to immobilise waste resulting from nuclear fuel reprocessing. One of these is vitrification – a mature technology which has been used for high-level nuclear waste immobilization for over 50 years…Argentina is considering vitrification as a viable option for dealing with its high-level nuclear waste. The Argentine National Programme for Radioactive Waste Management aims to build capacities to implement vitrification processes for radioactive waste….
