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...

Designed by Marin Teknikk and built by Kleven Verft, Norway, the US$157 million vessel will enable Debmarine Namibia, a 50/50 joint venture between the Government of the Republic of Namibia and De Beers Group, to explore diamond deposits and secure diamond supply in the country well into the future
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...
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 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
At Mines and Money London, SmallCapPower spoke with Mark Brown, Chairman of Avrupa Minerals Ltd. (TSXV: AVU), about the Company’s unique funding model. Over their five-year history, Avrupa has raised about $12 million by partnering with larger mining companies to fund drilling work. Hear Mr. Brown describe how shareholders get 50% more for every dollar they invest, and why their partners pay them to explore Avrupa’s projects.
BLACK SMOKERS: ORE FACTORIES OF THE DEEP At the bottom of the sea, in a depth of several thousand metres, black smokers bring up valuable raw materials from inside the earth. Their metre-high vents seem to give off smoke like under water industrial chimneys.

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

We take an ingenious look at the future. Hydrone, our resident intervention ROV, moves the industry a step closer to cost effective subsea field operations and maintenance, allowing the transition from vessel based operations to permanently integrated subsea technology.
An innovative project changing the face of the global mining industry. The construction of the world's first deep sea mining vehicles.
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.
Are Giant Robots the future Of Underwater Mining ScubaTube - http://bit.ly/2vHQnP7 Fun Vids - http://bit.ly/2mZLTzp A Canadian company called Nautilus Minerals have spent years prepping to mine an area called Solwara 1. The seabed is, of course, a massive area so the mining company has built three massive machines to mine the area, to put it into perspective the lightest machine weighs two hundred tons. At this moment in time, these machines live aboard a 700-foot ship, which is also where these robots will be controlled… so even the mothership is massive. Using cameras, 3D sonar and very powerful lights operators will be able to churn up the seabed with ease. ....................................
