De komende maanden zou Deme een proefprogramma starten waarbij mangaanknollen van de diepzeebodem worden opgehaald. In de Stille Zuidzee ten westen van Mexico is de Patania II te water gelaten, een rooimachine die in staat is op de bodem van de zee te opereren. De machine is met een navelstreng van zes kilometer verbonden met een onderzoeksschip aan het zeeoppervlak. Precies met deze verbinding is het de voorbije dagen misgelopen.

DNA analysis recently confirmed that Woods Hole Oceanographic Institution (WHOI) scientists and their collaborators at OceanX, the University of Connecticut (UConn), and NASA’s Jet Propulsion Laboratory (JPL) discovered two new species of deep-sea corals during a September 2018 expedition in the Northeast Canyons and Seamounts National Monument, located about 100 miles from the Northeast U.S. coast.

The total number of animals has halved since the 1970s in what some scientists have termed the start of Earth’s sixth mass extinction.

Seismic eruptions, ice ages, continental collision and asteroid impact are thought to be some of the causes of the previous five mass extinctions. This time though, humans are to blame. Never before has a single species exerted such influence on the planet and the evolution of its inhabitants, or put its own survival in such jeopardy.

The area to be investigated by the research project “Mining Impact” is located in the Clarion Clipperton Zone (CCZ) in the northeast Pacific at approximately 4,500 metres water depth shrouded in complete darkness. Here, in an area of five million square kilometres, manganese nodules are abundantly found on the seabed. Their metal content offers a potential for commercial deep-sea mining. In recent years mineral raw materials from the deep sea have become the focus of some countries and companies in order to secure their supply with high-tech metals.

No flag can claim the high seas, but many nations exploit them. As a result, life in the two-thirds of the oceans beyond any country’s territorial waters faces many threats that are largely unregulated, including overfishing and the emerging deep-sea mining industry.

For the first time, researchers have found microplastics in creatures that reside in the deepest parts of Earth’s oceans.

Researchers believe the discovery, outlined in a study published last month in the Royal Society Open Science journal, means that “it is highly likely there are no marine ecosystems left that are not impacted by plastic pollution.”
