Scientists fear that even before one of the last frontiers of exploration, the ocean deep, has been properly studied it will already have been exploited by commercial deep-sea mining looking for rare euronews knowledge brings you a fresh mix of the world's most interesting know-hows, directly from space and sci-tech experts.

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 ric...

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 une...
Join us as we highlight our sea floor production vessels and show and describe how our first location, Solwara1, will work. This video is full of information and explores in's and out's of how all of our equipment will work together to mine the sea floor.
In 1989 German ocean researchers started a unique long-term experiment off the coast of Peru. To explore the effects of potential deep sea mining on the seabed, they plowed in about eleven square kilometer area around the seabed. (c) GEOMAR Helmholtz Centre for Ocean Research Kiel 2016
This video shows how colonists make use of modest, pressurized outposts to mine vast deposits of precious minerals on the bottom of the oceanic trench.
The LARS was built by AxTech on behalf of Soil Machine Dynamics as part of Nautilus’ fabrication contract with Soil Machine Dynamics. It consists of very large A-frames, lift winches, hydraulic power units, electric power units and deck control cabins. The LARS will be used to launch and stabilize the Seafloor Production Tools during deployment from the vessel down to the seafloor and during retrieval from the seafloor back up to the vessel.

In subsea applications, pipes need to maintain their reliability and high quality performance; the best way to protect these pipes is to use Monel, Inconel, or any similar nickel alloy. Nickel alloys, in the oil and gas industry, have become extremely popular because of their corrosion resistance. At Continental Steel & Tube, we supply a wide variety of nickel alloys for marine applications and can provide you solutions for your subsea design. For more information on subsea applications of nickel alloys, check out our page here: http://metalspecialist.continentalsteel.com/blog/subsea-applications-of-nickel-alloys
Deep Tow Project Part I – Getting started Teledyne Benthos and Teledyne RESON are developing a new deep tow vehicle for Odyssey Marine Exploration. The vehicle is equipped with aSeaBat 7125 Multibeam Sonarand will be used to find shipwrecks on the seabed in very deep waters.The Vehicle will be about four meters long and are to be towed with a 10 kilometer cable form a surface vessel. We have followed the development process and in this first part Paul Jubinski from RESON gives an introduction to the project.Subscribe to our newsletterA Sharper Viewto get part II directly in your mail box.

The world’s first ever deep sea mining operation is scheduled to begin offshore from the Pacific island nation of Papua New Guinea in early 2018. In this short film we explore how the two Pacific Island nations of Papua New Guinea and Vanuatu are working together with their communities to manage the future opportunities and impacts associated with this emerging industry. While deep sea minerals could provide much needed revenue for several Pacific Island nations, questions remain about the impacts of mining on the marine environment and the many communities that depend on it for their livelihoods.
Nickel alloy refers to a substance that is a mixture of nickel and other metals that does not produce a chemical reaction.

The development of the BMT System®, which makes materials containing lignin (like e.g. straw and wooden residues) economically digestible in biogas plants, is an extraordinary success of MWK Bionik® GmbH. For many microorganisms, material containing lignin is difficult or not at all digestible, and thus not used when applying current technologies - it remains as solid fermentation residue. Within the BMT System® bacteria are being used to crack the complex and robust structure of lignocellulose. This video shows LignoX®-bacteria which have already cracked the lignin coating of the straw cells and are now visibly moving inside the cells. This is the visible proof for pre-digestion of lignocellulose. The highly efficient microorganisms and bacteria of LignoX® originate from extreme biotopes ...

Gold became highly concentrated as the result of global forces operating over hundreds of millions of years. Volcanoes, tectonic plates and erosion all combined to concentrate billions of dollars' worth of gold in the mountains of California. During the California Gold Rush, gold-seekers known as "Forty-Niners" retrieved this gold, at first using simple techniques, and then developing more sophisticated techniques, which spread around the world. Geologic evidence indicates that over a span of at least 400 million years, gold that had been widely dispersed in the Earth’s crust became more concentrated by geologic actions into the gold-bearing regions of California. Only gold that is concentrated can be economically recovered. Some 400 million years ago, rocks that would be accreted onto wes...
