  • How a Canadian company will mine the sea bed near Papua New Guinea

    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...

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. W​hile 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.

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.

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.

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 of the deep sea (4,000 to 6,000 m), the so-called “black smokers”. At temperatures of up to 380°C and a high ambient pressure, hydrothermal vents and subsea geysers emit minerals and metal sulphides into the oxygen-rich, cold seawater. In this acidic and sparse environment, bacteria are active, which, outside their native setting, have been optimized for the use of biogas plants in a high research effort and years of gradual cultivation. LignoX® as well as other products of MWK Bionik® now use this potential in the large scale.

Only gold that is concentrated can be economically recovered. Some 400 million years ago, rocks that would be accreted onto western North America to build California lay at the bottom of a large sea. Subsea volcanoes deposited lava and minerals (including gold) onto the sea floor; sometimes enough that islands were created. Between 400 million and 200 million years ago, geologic movement forced the sea floor and these volcanic islands and deposits eastwards, colliding with the North American plate, which was moving westwards. Beginning about 200 million years ago, tectonic pressure forced the sea floor beneath the American continental mass. As it sank, or subducted, beneath the western margin of the North American plate portions of the sea floor and overlying continental crust heated and melted, producing large molten masses (magma).
