They can then identify what they are made from and try to explain why there may be damage to the environment from them being there. The learners should list the items they see in the video that do not naturally occur in the sea. Sorting materials – are they where they should be? And so we really do feel like we're racing against time to learn as much as we need to to be able to protect and manage the deep ocean. And I think that would be a real loss for humanity. If it's not done in a responsible way, we maybe could potentially irreparably alter our deep ocean before we fully understand it. These animals are part of the food chain, so by harming them we could also affect other animals and the balance of life in our seas. If we began to take metals from the deep sea because they're running out on land then it could have a big impact on some of the animals that use these vents as a home. And as a result we're thinking about potentially mining these habitats. It has gold, silver, copper, iron, as well as a bunch of other metals that are running out on land. And you can see that this is pretty much a huge lump of metal. This is a piece of a chimney, of a hydrothermal vent chimney. Those are the kinds of questions that we just can't answer yet because we still know so little about the deep ocean.īut our rubbish is not the only man-made problem facing the deepest part of the sea. What kind of an impact are those metals that may be leaching out of that degrading container having on the life down there? And we found ourselves driving through a field of washing machines, refrigerators, dishwashers this is over a kilometre down in the Gulf of Mexico. When we got closer we realised that it was actually a 40ft shipping container that had been lost at sea. One of my most recent expeditions to the Gulf of Mexico, we were exploring a sonar target which we thought was a shipwreck. I think one of the saddest examples of our litter in the deep ocean is a plastic shopping bag was found at the bottom of the Marinara Trench, a place called Challenger Deep, which is over 10,000 metres down in the deep ocean, it's the deepest point on the planet.Īnd will probably be there for decades, if not centuries, if not millennia more.ĭiva's dives have found evidence of our junk almost everywhere. The deep sea is really the epitome of out of sight, out of mind. But it's much harder to find out how healthy the deep sea is. The damage on the surface on the water caused by pollution is easy to see for scientists like Diva. Which is just crazy because we're talking about our own planet here. And yet we've only explored about 1% of it. So while we may think that the deep ocean is this alien, remote place' it is absolutely fundamental to us being here on planet Earth. The ocean floor is actually less well-mapped than the surface of Mars, Venus and the Moon. The deep sea is absolutely the last unexplored frontier on our planet.
