Fracking explained in five minutes. Fracking is a controversial topic. On the one side the gas drilling companies, on the other citizen opposed to this drilling method. Politicians are also divided on the matter. We try to take a neutral look on fracking. It is relevant for all of us, because of high prices for energy and the danger for our drinking water. This video focuses mostly on the debate currently ongoing in europe. In a lot of european countries there is a public outcry against fracking, espacially in germany. But the facts in this video are relevant to all of us. Short videos, explaining things. For example Evolution, the Universe, Stock Market or controversial topics like Fracking.

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.

Follow us: Website: http://inhabitants-tv.org/ Facebook: facebook.com/inhabitantstv/ YouTube: youtube.com/channel/UCt0fB6C18nwzRwdudiC8sGg instagram: inhabitants_tv #inhabitants Written by anthropologist Stefan Helmreich, What is Deep Sea Mining? Episode 2: Deep Frontiers is a brief history about knowledge of the deep sea and its resources. It highlights the ambiguity of this history, as depictions of the deep changed throughout the nineteenth and twentieth centuries. Today, this knowledge informs discussions about the commercialization of biological and geological resources, with the deep sea fast becoming a zone of international dispute, opening up a debate about sustainable practices at sea. What is Deep Sea Mining? is a five episode web series 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 web series 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. Stefan Helmreich is Professor of Anthropology at MIT. He is the author of Alien Ocean: Anthropological Voyages in Microbial Seas, and, most recently, of Sounding the Limits of Life: Essays in the Anthropology of Biology and Beyond (Princeton University Press, 2016). His essays have appeared in Critical Inquiry, Representations, American Anthropologist, Cabinet, and The Wire. 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.

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.

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.

Its pioneers are scientists leveraging the latest technology to cast light on the massive and incomprehensibly dark environment that extends more than 35,000 feet down. Until recently, this world was known only to our planet’s most unearthly species. This is the story of our largest biome—and the people devoting themselves to understanding it and saving it for future generations. 40 years ago we discovered hydrothermal vents, which act as Earth's plumbing system, transporting chemicals and extreme heat from the molten core of our planet, helping to regulate the chemical makeup of the oceans. But this seemingly toxic environment is still home to life. Organisms that don’t need photosynthesis to survive can live down here. And with most of the seafloor left to explore, many species remain undiscovered. Studying these unlikely ecosystems can teach us about the earliest stages of life’s evolution here on Earth, and about the possibility of life on other planets. That’s why NASA is working with oceanographers to help plan the mission to explore Jupiter's ice-covered moon, Europa. And because these vents form in active volcanic zones, they also help us better understand how landforms and moves over time. Plus, the sludge that’s constantly spewing from the vents contains some of the most valuable metals known to man. [Guardian video journalist] “In the deep ocean, where the water is as dark as ink, lie riches that no treasure hunters have managed to retrieve. They are deposits of precious minerals, from cobalt to gold, that have tantalized miners and nations for decades...” In 2019, a Canadian company will make the first-ever attempt at extracting these minerals. Using the latest technologies and massive, custom designed vehicles, it aims to bring up $1.5 billion worth of metals from a single site 25km off the coast of Papua New Guinea. Nautilus says it will minimize environmental damage by using infrared cameras and sonar to pinpoint the exact location of ore deposits, allowing it to shred less of the ocean floor. But environmentalists aren’t buying it. Preserving a sensitive ecosystem 8,000 feet underwater from the impact of mining is just not that simple. Unfortunately, we may not have much choice. There’s growing demand for these metals, but dwindling supplies of them on land. Cobalt — for instance — is used in jet engines, lithium-ion batteries, and the computer or smartphone you’re watching this video on—and the machines we made it on. But this age-old clash between miners and environment is really just one chapter in a much larger story of technology development—innovations aimed at maintaining the delicate balance of the increasingly threatened ocean ecosystem. One such tool is the EK80 broadband acoustic echo sounder. It uses a range of frequencies to paint a much more comprehensive picture of the amount and types of species living in a selected area of water.

Can conservation save our ocean? | The Economist
 
27:05
The ocean is facing its greatest ever challenge - overfishing, pollution and climate change are all threatening the health of a resource on which the whole world depends. Click here to subscribe to The Economist on YouTube: http://econ.st/2G3TH9d The crew of this ship is on a mission to try and save one of the most endangered sea creatures on the planet. They’re in the middle of a marine protected area in Mexico - a conservation zone where certain types of fishing are banned. Local fishermen are poaching a species of fish that is so highly prized in China, they can make tens of thousands of dollars in just one night. With ocean life under threat from overfishing, pollution and climate change, could marine protected areas be the answer? Near the Mexican fishing town of San Felipe, on the The Upper Gulf of California... Conservation group, Sea Shepherd is working with the authorities to help enforce a Marine Protected Area - or MPA. A designated section of ocean to be conserved, managed and protected. Maintaining rich, diverse ecosystems is key for the health of the Ocean - and ultimately the survival of humanity. But ocean life is under threat. From plants to micro-organisms and animals, species are disappearing forever. Marine Biologist Patricia Gandolfo and the rest of the Sea Shepherd crew are here to stop poachers. Caught up in the nets of the criminal gangs and local fishermen is one particularly rare porpoise - the Vaquita. Worldwide there are thousands of sea species currently threatened with extinction. Losing just one species from the food chain can have a disastrous effect on an entire ecosystem. After it’s sold on, the Totoaba’s swim bladder can fetch up to $100,000 a kilo in China, where it’s prized for its medicinal properties. Critics disapprove of Sea Shepherds use of direct-action tactics in some of their campaigns, but in the Gulf of California, their presence is welcomed by the Mexican government. Globally, the fishing industry employs 260 million people, but many more subsistence fishermen depend on the ocean for their income. Local fisherman here claim protecting the ocean has limited how they can fish, destroying their way of life. Yet doing nothing may ultimately present more of a threat to their livelihoods. Currently Marine Protected Areas make up only 3.6% of the world’s ocean but a growing number of scientists are calling for 30% to be protected by 2030. Cabo Pulmo now has a thriving eco-tourism and diving industry. The environmental rewards provided by the MPA to the local community have been valued at millions of dollars a year - Far more than they ever made from fishing. The ocean is facing its greatest ever challenge - overfishing, pollution and climate change are all threatening the health of a resource on which the whole world depends. Marine protected areas can come in many forms. But if they are to be effective, they must align the need for conservation with the needs of those who depend on the ocean for survival. In order to avoid disaster–and to ensure a sustainable supply of fish for the future–far more of our ocean needs urgent protection.

Hot Fuzz movie clips: http://j.mp/1uwjDCy BUY THE MOVIE: http://amzn.to/uoaVE7 Don't miss the HOTTEST NEW TRAILERS: http://bit.ly/1u2y6pr CLIP DESCRIPTION: Angel (Simon Pegg) and Danny (Nick Frost) discover a huge cache of weapons hidden at a local farm. FILM DESCRIPTION: A top London cop who is so good at his job that he makes his fellow officers look like slackers by comparison is "promoted" to serve in the sleepy village of Sandford in this contemporary action comedy from the creators of Shaun of the Dead. Police constable Nicholas Angel (Simon Pegg) always gets his man, but these days his impeccable record seems to be more indicative of his fellow officers' shortcomings than his own formidable skills as a keeper of the peace. Loathe to stand idly by as their once respectable track record is steadily soiled by the hyper-competent actions of one lone overachiever, Sergeant Angel's superiors at the Met soon determine to remedy their problem by relocating the decorated constable to the West Country village of Sanford -- where tranquil garden parties and neighborhood watch meetings stand in stark contrast to the violent crime and heated gunplay of the city. As Sergeant Angel does his best to adjust to the relative calm of his new environment, his oafish new partner Danny Butterman (Nick Frost) strives to gain the respect of his fellow constables while sustaining himself on fantasies of his favorite action films and police shows. Later, just as it begins to appear as if Sergeant Angel has been relegated to an uneventful existence in the relative calm of the countryside, a series of horrific "accidents" lead him to suspect that the tranquil hamlet of Sanford has fallen prey to a sinister plot which reeks of foul play. Jim Broadbent, Timothy Dalton, Steve Coogan, and Martin Freeman co-star in the Edgar Wright film.

Video presentations from the Morss Colloquium. http://www.whoi.edu/page.do?pid=28896 Deep-Sea Mining of Seafloor Massive Sulfides: A Reality for Science and Society in the 21st Century Deep-sea hydrothermal vent systems are attracting considerable interest from commercial mining companies. Vent systems precipitate seafloor massive sulfide (SMS) deposits that are rich in copper, gold, silver, and zinc. Although commercial firms are targeting inactive SMS deposits, these deposits are so little studied that it is unknown whether they harbor unique species or ecosystems. The new frontier of deep-sea exploration and mining raises a number of questions about the sustainable use of these resources and potential environmental impacts. This Workshop and Colloquium was held on April 1 - 2, 2009, and brought together scientists, specialists in marine conservation, mineral economics, international law, the International Seabed Authority, national interests in SMS, and representatives of industry and NGOs to inform each other, and the public, about this important topic. The issue of deep-sea mining of SMS is of global importance, connected to the global economy, society, and the conservation of unique marine life.

What Is Water Pollution | Chemistry for All | FuseSchool
 
05:32
Learn the basics about water pollution, whilst learning about environmental chemistry. The substances mankind throws away have polluted lakes, rivers and even the oceans. The United Nations estimate that around 10% of the world’s people do not have access to clean drinking water. The main problem with this untreated water is that it can carry diseases, such as cholera, that spread through untreated human faeces. This is particularly serious in shanty towns near big cities and in refugee camps. Rivers and streams can also be polluted with diseases from water coming from badly managed rubbish dumps. But human sewage is not the only substance that pollutes our water supplies – most of the other substances humans allow to escape into streams, rivers and the oceans, are more a danger to natural ecosystems than to us directly. Chemical fertilisers are much more soluble in water than organic, manure-based fertilisers, so heavy rain can wash them into streams and lakes, causing eutrophication. The fertilisers cause algae to grow very fast forming a mat on the lake surface, which blocks sunlight from the vegetation deeper down, which then dies. Bacteria feed off the dying vegetation and use up the remaining oxygen supply. Once the oxygen has gone all animal life dies and the lake ecosystem is destroyed. If heavy metals, such as lead mercury and cadmium, get into rivers and lakes many animals will die. Radioactive waste is normally stored above ground in water tanks, waiting for a more permanent underground storage where it has to be safe for millions of years. There are fears that these underground stores could fail and contaminate water courses. Following a nuclear disaster, water courses and the oceans can become dangerously polluted with radioactive waste. During mining and drilling operations to extract minerals from the earth, aquifers, which are underground water courses, can become polluted. Huge amounts of plastic thrown away from ships, and washed out to sea from rubbish dumps on land, have ended up floating in huge islands of waste causing a serious threat to fish, seabirds and other marine animals. Coal and oil fuelled power stations have been responsible, more so in the past, for causing acid rain. Fossil fuel and nuclear power stations need large amounts of water for condensing the steam which drives their turbines. This water is usually cooled on site in the great cooling towers that dominate the skyline of power-stations. Even so the water will be returned to the river or sea warmer than before. This can upset the river or sea ecosystems. Although not material pollution this waste heat is a pollutant. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.
