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...
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.

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...
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.

http://www.euronews.com/ The second harvest of the year is being prepared in potato fields in Xylophagou, a speciality of the region in the south of Cyprus. But water from the surrounding dams isn't enough to sustain crops. To compensate, farmers pump the subsoil via illegal wells. Farmer Kostas Karagiannis told euronews about the difficulties of growing the crop. "Potatoes need a lot of water, so we create places to store water from our wells." Sometimes the water we draw from the wells is salty. To irrigate our crops with water, we mix it with dam water to reduce the amount of salt." Some 50,000 illegal wells have been identified in Cyprus; over the years, they've contributed to the depletion of the country's aquifers - water-bearing layers of underground rock. Among many other ...

Subsea Tooling Services (STS), an Aberdeen-shire based company offering a diverse range of subsea equipment, recently completed final tests of their new Predator Subsea Dredger at our open-water site in Fort William. Watch video from the trial and read more about how the subsea tests were achieved. Proving the Predator Subsea Dredger Their main objective was to prove that the Predator Subsea Dredger was as efficient, if not better, than the other dredgers that are currently on the market. As this dredging system is a new concept in the world market, STS needed to prove its capabilities to their clients and confirm their development tests by filming the dredger in action in conditions such as it will be used in offshore. The subsea trials more than exceeded their expectations in terms o...

Coming three years after the Macondo oil spill disaster, Shell targets first production by 2016, demonstrating confidence in big offshore projects in spite of a downturn in oil prices. Shell's 100 percent-owned Stones field was discovered in 2005, some 200 miles southwest of New Orleans. It encompasses eight lease blocks in the Gulf of Mexico's Lower Tertiary trend, which is the Gulf's deepest, most challenging and most promising play, ...
