How a Canadian company will mine the sea bed near Papua New Guinea
 
01:12
Canadian mining company Nautilus Minerals has reached an agreement with the government of Papua New Guinea to begin mining an area of seabed believed to be rich in gold and copper ores, according to the BBC. Under the terms of the agreement, Papua New Guinea will contribute $120 million to the operation and receive a 15 percent share in the mine. Environmentalists say the mine will devastate the area and cause long-lasting damage to the environment. The BBC reports that "the mine will target an area of hydrothermal vents where superheated, highly acidic water emerges from the seabed, where it encounters far colder and more alkaline seawater, forcing it to deposit high concentrations of minerals." The report continues: The result is that the seabed is formed of ores that are far richer in gold and copper than ores found on land. Mike Johnston, chief executive of Nautilus Minerals told the BBC "that a temperature probe left in place for 18 months was found to have 'high grade copper all over it'." Nautilus announced in April that it had completed its bulk cutter, the first component of its Seafloor Production Tools system, which will be used to mine the seabed. Nautilus also approximately 500,000 square kilometres of "highly prospective exploration acreage" in Papua New Guinea, the Solomon Islands, Fiji, Vanuatu and Tonga, as well as in international waters in the eastern Pacific, the company said in a press release. ----------------------------------------­­---------------------------------------­-­---------------- Next Animation Studio’s News Direct service provides daily, high-quality, informative 3D news animations that fill in for missing footage and help viewers understand breaking news stories or in-depth features on science, technology, and health.

TechKnow - Deep sea gold rush
 
23:43
Oceans cover 70 percent of the earth's surface, but only a fraction of the undersea world has been explored. On this episode of TechKnow, Phil Torres joins a team of scientists on a special expedition to explore and uncover the mysteries at the bottom of the ocean floor. "What we are doing is similar to astronauts and planetary scientists just trying to study life on another planet," says Beth Orcutt, a senior research scientist. The journey begins in Costa Rica aboard the R/V Atlantis, a research vessel operated by the Woods Hole Oceanographic Institution. From there, Phil gets the chance to take a dive with Alvin, a deep-water submersible capable of taking explorers down to 6,000 metres (20,000 feet) under the sea. Commissioned in 1964, Alvin has a celebrated history, locating an unexploded hydrogen bomb off the coast of Spain and exploring the famous RMS Titanic in the 1980s. Alvin and its first female pilot, Cindy Van Dover, were the first to discover hydrothermal vents, which are underwater springs where plumes of black smoke and water pour out from underneath the earth's crust. The vents were inhabited by previously unknown organisms that thrived in the absence of sunlight. After 40 years of exploration, Alvin got a high-tech upgrade. The storied submersible is now outfitted with high-resolution cameras to provide a 245-degree viewing field and a robotic arm that scientists can use to pull samples of rock and ocean life to then study back on land. But scientists are not the only ones interested in the ocean. These days the new gold rush is not in the hills, it is in the deep sea. For thousands of years miners have been exploiting the earth in search of precious metals. As resources on dry land are depleted, now the search for new sources of metals and minerals is heading underwater. The National Oceanic and Atmospheric Administration's national ocean service estimates that there is more than $150tn in gold waiting to be mined from the floor of the world's oceans. "The industry is moving very, very fast. They have far more financial resources than the scientific community," says Cindy Van Dover, Alvin's first female pilot and Duke University Oceanography Professor. Seabed mining is still in the planning stages, but Nautilus Minerals, a Canadian mining company, says it has the technology and the contracts in place with the island nation of Papua New Guinea to start mining in its waters in about two years. What is the future of seabed mining? And what are the consequences of seabed mining for the marine ecosystems? Can science and industry co-exist and work together on viable and sustainable solutions? - Subscribe to our channel: http://bit.ly/AJSubscribe - Follow us on Twitter: https://twitter.com/AJEnglish - Find us on Facebook: https://www.facebook.com/aljazeera - Check out our website: http://www.aljazeera.com/

Michio Kaku predicts asteroid mining will happen sooner than you think
 
04:14
Good news! We're on the precipice of the next great gold rush... but it won't be in the hills of California. Or anywhere on this planet. It'll be in outer space, as there are untapped rare materials in asteroids that could be used for future technologies. That's right: there's gold in them thar skies! Theoretical physicist and one of our favorite Big Thinkers, Dr. Michio Kaku, explains to us that while China might have a stranglehold on the rare minerals and metals on our planet, there's no stopping interplanetary mining. We've even got an actual plan with actual economics already in place... we just have to wait until NASA's SLS rocket technology fully develops. Michio Kaku's latest book is the awesome The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality, and Our Destiny Beyond Earth Read more at BigThink.com: http://bigthink.com/videos/michio-kaku-asteroid-mining-will-happen-sooner-than-you-think Follow Big Think here: YouTube: http://goo.gl/CPTsV5 Facebook: https://www.facebook.com/BigThinkdotcom Twitter: https://twitter.com/bigthink Transcript: When I was researching my book The Future of Humanity I came across a comment made by Thomas Jefferson. Thomas Jefferson made the biggest gamble of his life buying the Louisiana Purchase from Napoleon. Napoleon was fighting the British he needed hard cash immediately. He had Louisiana and that whole middle portion of the United States and so Napoleon sold it to Thomas Jefferson for a song. But Thomas Jefferson thought how long would it take to investigate what he had just purchased? He had doubled the size of the USA. Think about that. And he probably violated the Constitution in the process. Everyone forgets that. Everyone glosses over that fact, but hey when Louis and Clark went into the territories that comprised the Louisiana Purchase they found tremendous prospects for wealth and prosperity, but Thomas Jefferson wrote that it may take a thousand years, a thousand years before they could then begin to settle the west. Well, how long did it take? A few decades because what happened? Gold. Gold was discovered in California sparking the gold rush and within just a few years millions of prospectors, settlers, fortune hunters converged on California. It didn’t take a thousand years to develop that. Then the question now is is there going to be a new gold rush in outer space? Some people think so. Some Google billionaires have created an organization, a company, Planetary Resources, that are looking into prospecting in the asteroid belt. Now, asteroids come in all shapes and sizes and we’re cataloging them now and we have already found some perspective asteroids that could be mined. One asteroid perhaps maybe 30/50 feet across brought back down either to the moon or to the planet earth could in fact yield billions of dollars in rewards because of the rare earths and the platinum type medals that you find inside. You see, the electronics industry is dependent upon rare earths. Where are these rare earth elements found it? Mainly in China. They’re everywhere, of course, but China has the most developed market and the Chinese in turn supply on the order of 90 percent of the rare earths. Well, a few years ago they decided to capitalize that and raise the price. All of a sudden shockwaves, shockwaves spread around the earth because people realized that oh my God China has a stranglehold, a stranglehold on high technology. How can you build the next iPhone if you don’t have the rare earths to make the transistors and to make the delicate components of these high tech devices? So I think what’s happening here is that some people see an area for profit and that is asteroid mining. Now of course, the infrastructure for that doesn’t exist, but NASA has looked at its budget and does have a program that has been shelved temporarily to redirect an asteroid. The Asteroid Redirect Program is to send of the SL ass booster rocket into outer space with the Orion capsule. It will then intercept an asteroid and bring it back to orbit around the moon. Then it can be mined as it orbits around the moon or as it’s brought back to planet earth. And so this is now beyond the phase of science fiction. We’re no longer talking about dreaming about an asteroid redirect, we’re talking about an actual plan with the economics, with the details laid out. However, at the present time we have to wait for NASA’s SLS rocket to mature to the point where we can intercept an asteroid.

HUGHES GLOMAR EXPLORER   MINING MINERALS IN THE DEEP OCEAN  MAGANESE NODULE RECOVERY  22324
 
14:25
“Oceanography: Mining Mineral In The Ocean” is an issue of the Science Screen Report, presented by United Technologies Sikorsky Aircraft, that discusses the potential and problems of have deep-sea mining for minerals. The issue opens with shots of the sea, which is a “reserve of global resources,” including metals from deep-sea nodules (polymetallic nodules). These nodules cover vast areas of the sea bottom, and their potential is the reason for a major deep-ocean project being carried out. Deep Sea Nodules can be the size of potatoes, and their porous structure accumulates layers of various metals. They are very slow growing, but sizeable nodules cover areas of the sea floor, providing a significant reserve of metals. As part of the project to determine the mining feasibility of nodules, the first self-propelled robot miner (01:38) is developed and tested. Scientists examine nodules in a lab (02:52), but to answer a number of questions surrounding them, the National Science Foundation uses Research Vessel Melvillle (03:12) to carry out underwater tests. Members of the crew lower sound beacons to create a grid (03:35). Then a robot mapping vehicle is lowered into the water to gather data within the grid. In the control room (04:10), the team monitors the robot’s data. The next step is the collection of sea floor samples (05:08); a box corer is lowered into the water to gather sample nodules, transporting nodules and their environment to the surface. Scientists examine the contents, conduct tests, and record data. The results indicate nodules may grow similar to coral. Next, piston corers (06:52) are used to take out samples of core sections of the floor to add to the mission’s overall understanding. After two weeks, the samples and data are collected, stored, and made accessible to over 50 research centers throughout the world. The next phase involves exploration ship Governor Ray (08:06), which monitors a sea mining research site, and Glomar Explorer (08:22), a surface platform ship (originally built as a deep-sea recovery platform for the CIA as part of Project Azorian also known as Project Jennifer) with an internal dry dock that holds the advanced robot miner. The crew preps for launch day by filling the dry dock, opening the doors (11:00), and moving the robot miner into the water. The robot miner hangs under the ship as pipe attachments are installed, connecting the miner and processor to transport nodule slurry. The robot miner is positioned and the processor is attached to it, enabling the mining operation to begin (12:18). Sonar and TV images show how easily the miner collects nodules as is moves across sea floor capturing images and harvesting nodules, which are crushed into a slurry and piped up to the ship. A commercial miner would be 10 times the size of the robot miner, but the smaller robot miner is the first step in the eventual commercial mining of the sea’s unique nodules. Background on this ... historic film is that it shows techniques used to conduct deep ocean mining of the sea floor, which were pioneered in the 1960s. The potential for this type of mining (particularly of manganese nodules) was never fully realized. Ironically, the program did end up providing the cover for the USNS Hughes Glomar Explorer (T-AG-193), a deep-sea drillship platform built for the United States Central Intelligence Agency Special Activities Division secret operation Project Azorian to recover the sunken Soviet submarine K-129, lost in April 1968. Hughes Glomar Explorer (HGE), as the ship was called at the time, was built between 1973 and 1974, by Sun Shipbuilding and Drydock Co. for more than US$350 million at the direction of Howard Hughes for use by his company, Global Marine Development Inc. This is equivalent to $1.67 billion in present-day terms. She set sail on 20 June 1974. Hughes told the media that the ship's purpose was to extract manganese nodules from the ocean floor. This marine geology cover story became surprisingly influential, spurring many others to examine the idea. But in sworn testimony in United States district court proceedings and in appearances before government agencies, Global Marine executives and others associated with Hughes Glomar Explorer project unanimously maintained that the ship could not be used in any economically viable ocean mineral operation.

The deep ocean is the final frontier on planet Earth
 
14:49
The ocean covers 70% of our planet. The deep-sea floor is a realm that is largely unexplored, but cutting-edge technology is enabling a new generation of aquanauts to go deeper than ever before. Click here to subscribe to The Economist on YouTube: http://econ.trib.al/rWl91R7 Beneath the waves is a mysterious world that takes up to 95% of Earth's living space. Only three people have ever reached the bottom of the deepest part of the ocean. The deep is a world without sunlight, of freezing temperatures, and immense pressure. It's remained largely unexplored until now. Cutting-edge technology is enabling a new generation of aquanauts to explore deeper than ever before. They are opening up a whole new world of potential benefits to humanity. The risks are great, but the rewards could be greater. From a vast wealth of resources to clues about the origins of life, the race is on to the final frontier The Okeanos Explorer, the American government state-of-the-art vessel, designed for every type of deep ocean exploration from discovering new species to investigating shipwrecks. On board, engineers and scientists come together to answer questions about the origins of life and human history. Today the Okeanos is on a mission to investigate the wreck of a World War one submarine. Engineer Bobby Moore is part of a team who has developed the technology for this type of mission. The “deep discover”, a remote operating vehicle is equipped with 20 powerful LED lights and designed to withstand the huge pressure four miles down. Equivalent to 50 jumbo jets stacked on top of a person While the crew of the Okeanos send robots to investigate the deep, some of their fellow scientists prefer a more hands-on approach. Doctor Greg stone is a world leading marine biologist with over 8,000 hours under the sea. He has been exploring the abyss in person for 30 years. The technology opening up the deep is also opening up opportunity. Not just to witness the diversity of life but to glimpse vast amounts of rare mineral resources. Some of the world's most valuable metals can be found deep under the waves. A discovery that has begun to pique the interest of the global mining industry. The boldest of mining companies are heading to the deep drawn by the allure of a new Gold Rush. But to exploit it they're also beating a path to another strange new world. In an industrial estate in the north of England, SMD is one of the world's leading manufacturers of remote underwater equipment. The industrial technology the company has developed has made mining possible several kilometers beneath the ocean surface. With an estimated 150 trillion dollars’ worth of gold alone, deep-sea mining has the potential to transform the global economy. With so much still to discover, mining in the deep ocean could have unknowable impact. It's not just life today that may need protecting; reaching the deep ocean might just allow researchers to answer some truly fundamental questions. Hydrothermal vents, hot springs on the ocean floor, are cracks in the Earth's crust. Some claim they could help scientists glimpse the origins of life itself. We might still be years away from unlocking the mysteries of the deep. Even with the latest technology, this kind of exploration is always challenging. As the crew of the Okeanos comes to terms with a scale of the challenge and the opportunity that lies beneath, what they and others discover could transform humanity's understanding of how to protect the ocean. It's the most hostile environment on earth, but the keys to our future may lie in the deep.

What is Deep Sea Mining? A web series. Episode 1: Tools for Ocean Literacy
 
06:45
Inhabitants is an online video for exploratory video and documentary reporting. Follow us: Website: http://inhabitants-tv.org/ Facebook: https://www.facebook.com/inhabitantstv/ YouTube: https://www.youtube.com/channel/UCt0fB6C18nwzRwdudiC8sGg What is Deep Sea Mining? is a five episode webseries dedicated to the topic of deep sea mining, a new frontier of resource extraction at the bottom of the ocean, set to begin in the next few years. Deep sea mining will occur mainly in areas rich in polymetallic nodules, in seamounts, and in hydrothermal vents. Mining companies are already leasing areas in national and international waters in order to extract minerals and metals such as manganese, cobalt, gold, copper, iron, and other rare earth elements from the seabed. Main sites targeted for future exploration are the mid-atlantic ridge and the Clarion Clipperton Zone (Pacific ocean) in international waters, as well as the islands of Papua New Guinea, Fiji, Tonga, New Zealand, Japan, and the Portuguese Azores archipelago. Yet, potential impacts on deep sea ecosystems are yet to be assessed by the scientific community, and local communities are not being consulted. The prospects of this new, experimental form of mining are re-actualizing a colonial, frontier mentality and redefining extractivist economies for the twenty-first century. This webseries addresses different issues related to this process, from resource politics to ocean governance by international bodies, prompting today’s shift towards a "blue economy" but also efforts to defend sustained ocean literacy when the deep ocean, its species, and resources remain largely unmapped and unstudied. Episode 1: Tools for Ocean Literacy is a cartographical survey of technologies that have contributed to ocean literacy and seabed mapping. Structured around a single shot along a vertical axis, the episode inquires about deep sea mining and the types of geologic formations where it is set to occur, particularly hydrothermal vents. Understanding the process of deep sea mining demands not only a temporal investigation – its main dates, legal, and corporate landmarks, and scientific breakthroughs – but also a spatial axis connecting the seafloor to outer space cartographic technologies. After all, we know less about the ocean depths than about the universe beyond this blue planet. What is Deep Sea Mining? is developed in collaboration with Margarida Mendes, curator and activist from Lisbon, Portugal, and founding member of Oceano Livre environmental movement against deep sea mining. It was commissioned and funded by TBA21 - Academy and premiered at the 2018 New Museum Triennial: Songs for Sabotage.

Congo, My Precious. The Curse of the coltan mines in Congo
 
52:01
Watch more https://rtd.rt.com/tags/illegal-mining/ The Democratic Republic of Congo in Africa is one of the world’s most resource-rich countries. A wide range of rare minerals can be found here in abundance, all commanding high prices in world commodity markets. Diamonds for jewellery, tantalum, tungsten and gold for electronics; uranium used in power generation and weaponry and many others. Congo has copious deposits of raw materials that are in high demand internationally but remains one of the poorest countries in the world. From colonisation, with the horrors of slavery and other atrocities, to a turbulent and equally brutal present in which militant groups control the mines, Congo’s richness in natural resources has brought nothing but misery. Referred to as “conflict minerals”, these riches leave only a trail of death, destruction and poverty. Under Belgian rule, Congolese labourers were often required to meet quotas when mining different minerals. Failure could mean punishment by having a hand cut off with a machete. The country gained independence in 1960, but that didn’t put a stop to slave and child labour or to crimes being committed to extract and exploit the minerals. Warring militant fractions from inside the country and beyond seized control of mines for their own benefit while terrorising local populations. For our translator, Bernard Kalume Buleri, his country’s history of turmoil is very personal; like most Congolese people, he and his family fell victim to the unending mineral based power struggle. Born in the year of his country’s independence, he has lived through war and seen his homeland torn apart by violent looting and greed. His story is a damning testament, illustrating how nature’s bounty, instead of being a blessing, becomes a deadly curse.

Legal Pathways for Addressing Environmental Harm in Deep Seabed Mining Activities
 
03:22
Everyone is aware of off-shore oil rigs; these platforms drill down underwater for valuable resources just off the coast of many nations. But, deep in the ocean beyond national aquatic boundaries lies an abundance of natural resources such as gold, copper, manganese and zinc. State-sponsored companies are surveying and staking claim to these resources, but so far, no one has been granted approval to begin extracting them. The International Seabed Authority (ISA) — the governing body that oversees all activities in international waters (known as the Area) — is currently developing regulations for the extraction of marine minerals. Rules and procedures that govern liability for damage arising from mining activities will be crucial aspect of this regulatory framework. Who is responsible when an environmental disaster occurs as a result of mining activities? To assist in clarifying these legal issues of responsibility and liability, the Centre for International Governance Innovation (CIGI), the Commonwealth Secretariat and the Secretariat of the International Seabed Authority established the Liability Issues for Deep Seabed Mining project. Under the direction of Neil Craik (CIGI), Hannah Lily (Commonwealth Secretariat) and Alfonso Ascencio-Herrera (ISA Secretariat), this project seeks to provide a foundational understanding of key questions surrounding the further development of liability rules.

The Largest Oil Rig in The World
 
19:43
Perdido is the deepest floating oil rig (platform) in the world at a water depth of about 2450 meters operated by the Shell Oil Company in the Gulf of Mexico. The Perdido is located in the Perdido fold belt which is a rich discovery of crude oil and natural gas that lies in water that is nearly 8000 feet deep. The platform's peak production will be 100,000 barrels of oil equivalent per day. At 267 meters, the Perdido is nearly as tall as the Eiffel Tower. An oil rig is a large structure with facilities to drill wells, to extract and process oil and natural gas, and to temporarily store product until it can be brought to shore for refining and marketing. In many cases, the platform contains facilities to house the workforce as well.

World's Deepest Mine - Gold Alchemy
 
04:51
South Africa's TauTona mine, real life alchemy, and Halicephalobus Mephisto. Footage from the 2012 documentary, "Down to the Earth's Core". We have travelled into space and looked deep into the universe's depths, but the world beneath our feet remains unexplored and unseen. Now, that's about to change. For the first time in one epic unbroken shot, we embark on an impossible mission - using spectacular computer generated imagery to smash through three thousand miles of solid rock, and venture from our world into the underworld and on to the core of the Earth itself. It's a journey fraught with danger. One thousand feet down we find ourselves inside one of the planet's most volatile places - the San Andreas Fault. Caught between two huge rock slabs, we watch as stress builds and then releases. It unleashes an earthquake and blasts us on towards rivers of molten rock, explosive volcanoes, tears in the Earth's crust and giant tornadoes of liquid metal. But for every danger, there are wonders beyond imagination. Four hundred feet below the surface, a three hundred million year old fossilized forest, with every leaf and every piece of bark perfectly preserved. At one thousand feet down we enter a cave of giant crystals, glistening in deadly 122 degree heat. More than two miles underground we find buried treasure - gold and gems. Deeper still there are valuable resources - salt, oil, coal and iron. And over one hundred miles down we see the sparkling beauty of diamonds. As we descend we piece together our planet's extraordinary story. We rewind time to discover how prehistoric forests became modern-day fuel. 1700 feet down a layer of rock reveals the extraordinary story of the dinosaurs' cataclysmic death. We watch stalactites form and gold grow before our eyes. The deeper we travel into the underworld the more we understand our world above the surface. A bigger picture takes shape - a cycle of destruction and creation, driven by the core that sustains our dynamic planet and makes the Earth the only planet with life in a seemingly lifeless universe. Until, finally, three thousand miles down, we reach the core. Inside it lie the secrets of life as we know it - the magnetic force field that protects life on Earth from the sun's deadly rays, the ancient heat source that keeps our planet alive. Down to the Earth's Core brings the latest science together with breathtaking computer generated imagery. The result is an unmissable journey into an extraordinary world - full of dangers, wonders and secrets. And it's all down there, beneath our feet, right now waiting to be discovered.

NIOZ-STW: Study on the possible consequences of Deep Sea Mining on the ecosystem near the Azores
 
10:45
(Nederlandse tekst na Engels) Can valuable mineral resources on the ocean floor be responsibly mined? To answer this question, we need to know much more about the deep-sea environments where these minerals occur in high concentrations. In April 2015, an international team of marine scientists sailed with the Dutch research vessel 'Pelagia' of Royal NIOZ to a site southwest of the Azores. Their mission: to collect data and perform experiments around a deep-sea hydrothermal vent field located on the Mid Atlantic Ridge. Sulfide minerals precipitating from the hydrothermal exhausts locally form massive sulfide deposits at the seafloor. In places where hydrothermal activity has ceased, these mineral deposits may become economically viable mining sites. Scientific understanding of the key geological, oceanographic and biological processes at those sites is of pivotal importance for policy makers to weigh the potential gain of valuable minerals against the potential environmental risks of deep sea mining. NL: Kunnen waardevolle mineralen op de bodem van de oceaan op een verantwoorde manier gewonnen worden? Om deze vraag te kunnen beantwoorden moeten we eerst veel meer te weten komen over de diepzeemilieus waar deze mineralen gevonden worden. In april 2015 vertrok een internationaal team van wetenschappers met het NIOZ onderzoeksschip 'Pelagia' naar een gebied ten zuidwesten van de Azoren. Hun missie: data verzamelen en experimenten uitvoeren rond diepzee-heetwaterbronnen op de Mid Atlantische Rug. Rondom de heetwaterbronnen zijn in de loop van de tijd metaalrijke mineraalafzettingen gevormd met potentieel economische waarde, maar ook wordt er een uniek ecosysteem aangetroffen met bijzondere levensvormen die aangepast zijn aan het extreme milieu. Afgraven van mineralen rond actieve heetwaterbronnen lijkt daarom vanuit milieu-oogpunt een onverantwoorde keuze, maar zou mogelijk wel plaats kunnen vinden op plaatsen waar de hydrothermale activiteit is uitgedoofd. Voor een verantwoorde beleidsafweging van economisch voordeel en mogelijke schade aan het diepzeemilieu is een goed begrip van de fysische, chemische, biologische en geologische sleutelprocessen absoluut onmisbaar.
