Gold alone found on the sea floor is estimated to be worth $150 trn. But the cost to the planet of extracting it could be severe.

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.

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.
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.
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 natural mineral product MagnaDense provides high density and heavy weight to offshore constructions such as platforms or wind parks ensuring a stable foundation or to keep these floating and stable for all wind and sea conditions.

Nickel alloy refers to a substance that is a mixture of nickel and other metals that does not produce a chemical reaction. Understand the difference between alloys with information from a geology professor in this free video on rocks. Expert: Jeffrey K. Wagner Bio: Jeffrey K. Wagner is an associate professor of astronomy and geology. He has been a faculty member of Bowling Green State University Firelands since 1981. Filmmaker: Bradley Walton
The ocean has a wealth of resources. From food, to travel, to pharmaceutical needs, and to energy, the ocean has always provided for mankind. And now, mankind is turning to the ocean for minerals and metals needed for the technology we use in our everyday lives. An exploration into the emerging industry of deep sea mining leads to more questions than answers. Read more: http://pulitzercenter.org/projects/underwater-mining-pacific-ocean
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
"Nickel" is a chemical element with symbol "Ni" and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel shows a significant chemical activity that can be observed when nickel is powdered to maximize the exposed surface area on which reactions can occur, but larger pieces of the metal are slow to react with air at ambient conditions due to the formation of a protective oxide surface. Even then, nickel is reactive enough with oxygen that native nickel is rarely found on Earth's surface, being mostly confined to the interiors of larger nickel–iron meteorites that were protected from oxidation during their time in space. On Earth, such native nickel is found in combination with iron, a r...
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 ...

NAUTILUS LIVE 2014 | E/V Nautilus is exploring the ocean studying biology, geology, archeology, and more. Watch http://www.nautiluslive.org for live video from the ocean floor. For live dive updates follow along on social media at http://www.facebook.com/nautiluslive and @evnautilus on Twitter. For more photos from our dives, check out our Instagram @nautiluslive. The largest off-shore coral community found on the continental United States is at Pulley Ridge. Originally discovered in 1950 and rediscovered in 1999, Pulley ridge has been rigorously studied based on its unique biology, location, and depths.
