A "new frontier" in mining is set to be opened up by the underwater extraction of resources from the seabed off the coast of Papua New Guinea, despite vehement objections from environmentalists and local activists. Canadian firm Nautilus Minerals has been granted a 20-year licence by the PNG ...
RSC keeps track of all the seabed mining news as it breaks.
Mining the sea sand A recent application for resource consent by Kaipara Excavators to mine large quantities of sea sand over a vast area of sea bottom, during a projected period of over 30 years, has raised concern with
In a bin full of old batteries awaiting recycling, what is the probability that a closed circuit will form, allowing electrical current to flow and potentially cause a fire?
The seabed authority bases its decisions in large part on scientific data gathered by the mining contractors themselves during surveys of marine life and seabed conditions, as well as the results of computer modeling and laboratory testing of potential mining impacts. Other data comes from independent scientists conducting deep-sea research.
Mining companies (known as contractors) will receive 30-year licenses to mine the deep sea. The draft regulations detail their obligation to conduct environmental assessments and minimize the impact of seabed mining. But it leaves unanswered for now the scientific standards that will determine whether a proposed mining operation would
Aside from direct impact of mining the area, leakage, spills, and corrosion would alter the mining area's chemical makeup. Among the impacts of deep sea mining, sediment plumes could have the greatest impact. Plumes are caused when the tailings from mining (usually fine particles) are dumped back into the ocean, creating a cloud of particles floating in
Deep seabed mining is the extension of terrestrial and shallow-water mining activities in the deep ocean in the quest for minerals. It requires new technologies and approaches and new scientific knowledge, most of which have yet to be acquired and developed. Learn more about the deep-sea here. There is widespread concern about the impact

A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic watersconsidered as one global ocean or as several principal oceanic divisions.
This paper considers the future effects of seabed mining on the cobalt, copper, manganese, and nickel industries, and the implications for producing and consuming states. The analysis is qualitative, or con-
Deep seabed mining could have serious impacts on the ocean environment and the future livelihoods and wellbeing of coastal communities. Only 3% of the oceans are protected and less than 1% of the high seas, making them some of the least protected places on Earth. The emerging threat of seabed mining is an urgent wake-up call.
Allowing seabed mining for iron sand off the Taranaki coast did not take account of Māori interests, a lawyer says.
Unlike land-based mining, seabed mining occurs where people do not live and requires little production infrastructure, all of which can be moved after mining is complete. And it offers increased worker safety with the operations being conducted remotely and no one at the cutting face, Smith said.
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines.Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, an enemy vessel.
World leaders are now mobilising to address concerns, not just about seabed mining, but about how to safeguard ocean systems which are increasingly recognised as critical to global food security and a healthy planet. US secretary of state John Kerry, ...

Three major shorelines were left by Lake Bonneville, and one by the Great Salt Lake. The Provo and Bonneville shorelines of Lake Bonneville can be seen as terraces or benches along many mountains in western Utah.
04 Sep 2017. Mining deep-sea mineral deposits is on the horizon, but how will this new process affect the environment? Its long been known that the seabed is a rich source of extractable minerals and deposits, often in higher concentrations than terrestrial mines.
The EPA has set down 109 conditions, but many are still to be developed, such as the effect of seabed mining on marine mammals and seabirds, said Cindy Baxter. We are also raising other issues, such as natural justice, the way economic benefits have been calculated, and the role of the precautionary approach.
Demandite is the word used by mineral economists to describe the materials that must be provided usually by mining to meet the needs of civilization.
