GOBLIN SHARK CHALLENGER DEEP HOW TO

Some examples of sharks that live in the Euphotic zones are Gray Nurse shark, Bull shark, Great Hammerhead shark, Whale shark, Galapagos shark and Salmon shark.Īnother group of sharks can dive up to the Twilight or Disphotic Zone. There are sharks that can live only within the sunlit areas or Euphotic zones. I learned that different kind of sharks can dive only at certain depths in the ocean. I also wonder what the tube worms eat since he did not mention it in his blog.ĭue to my interest, I also did some research about animals that live in the deep.

I am wondering how much they weigh or whether they can be eaten and how to cook them in a pot. I like going back to Carson’s post because it has interesting facts about deep sea creatures like the giant Japanese Spider crab which is 3.7 meters long. It was also interesting that the crab can live up to 100 years old. I like the part where Carson mentioned the Giant Spider Crab because I have seen a BBC documentary before and I saw that it fed on the carcass of a dead Sperm whale. I am most interested about the animals that I have never heard before such as the Frilled Shark, Atlantic Wolf Fish Pair and the Six Gilled Shark. We expect it to recover quite quickly.I like the post that Carson made about creatures that live beneath the Challenger Deep area – the deepest known point in the Earth's seabed. An active venting site 1km to the south-east has the same bugs and snails and the current will carry the bugs and snails to the mine site. Stressing the relatively small scale of the new mining operation, Mike Johnston, Nautilus’s CEO, told the BBC in 2014: 'It's a resilient system and studies show that life will recover in 5-10 years. Copper ore within the licensed area occurs with a concentration of 7 per cent copper, compared with an average of 0.6 per cent for most deposits found in the world’s mines today. The abundance of copper in the Nautilus concession underlines the scale of the opportunity for investors. These huge machines, each the size of a small house, will be deployed to scour the seabed for gold, platinum, nickel, copper and other deposits. The very first serious effort to mine the seabed is expected to begin in 2019, when the Canadian firm Nautilus Minerals launches remote control mining robots. In the same year UK Seabed Resources, a division of US defence giant Lockheed Martin, acquired a licence and contract to explore an area of seabed lying 4,000 metres deep, off the coast of Mexico. As journalist Nicola Wood has pointed out, rare earth metals are needed for solar panels, wind turbines, fluorescent light bulbs and batteries, but restricted supply is preventing many technologies from becoming commercially viable. Yet for all the damage undersea mining may cause, the benefits of discovering new sources of rare earth metals for renewable technologies could be substantial. But the more scientists do learn about the deep sea, the less it appears as a lifeless abyss, and the more fundamental this world appears to be for both the wider marine environment and, as a carbon sink, the regulation of the Earth’s climate. Our poor understanding of both the seabed and the ways the different ocean layers are inter-dependent means that the consequences of widespread mining activity are hard to predict. The animals that live on the plains endure temperatures below 5C, take longer to grow and longer to reach sexual maturity.

But extracting from around the vents could endanger the little-understood marine life that has emerged around these formations.Īway from the vents, extraction of polymetallic nodules from the undersea ('abyssal') plains where they are found could result in large dust plumes from mining machinery, endangering filter-feeding organisms. The areas surrounding the vents are rich in minerals that emanate from the “chimneys”.

One area of concern for the DSM campaign is the potential impact on hydrothermal vents, first found by Alvin. Furthermore, the limited scientific research conducted to date provides no assurance that the health of coastal communities and the fisheries on which they depend can be guaranteed.” “It is also occurring without meaningful participation by the communities who will be affected by DSM in decision-making. “This DSM exploration frenzy is occurring in the absence of regulatory regimes or conservation areas to protect the unique and little-known ecosystems of the deep sea,” Dr Helen Rosenbaum of the DSM Campaign says. For the Deep Sea Mining campaign, the rush to prospect the seabed is unregulated and carries risks to both the marine environment and coastal communities.Īlthough no actual deep sea mining (DSM) activities have begun, mining firms have taken out exploratory licences on 1.5 million square miles of the Pacific.
