We've mapped more of the moon and Mars than our own ocean floor. Charles and Sophia explore the surprising facts about what lies in the 80% of the ocean that remains a mystery, from undiscovered species to hidden volcanoes and deep-sea trenches. They'll also discuss the new technology that is finally allowing us to see what's down there.
00:11Today, we're talking about a very surprising fact.
00:14We've mapped more of the moon and Mars than we have our own ocean.
00:18Sophia, I know you've been doing a lot of research on this, and I'm very curious to hear about it.
00:22Thank you, Charles. It's a great topic.
00:23A lot of people think that we've explored our own planet, but the truth is over 80% of our oceans remain unmapped.
00:28It's like we're living in a house, but we've only explored the living room.
00:32That's a great way to put it. So what's the technology we're using to map the ocean?
00:35The main technology is a multi-beam sonar, which is a system that sends out sound waves and measures how long it takes for them to return.
00:42We also have autonomous underwater vehicles that can go down to the deepest parts of the ocean.
00:47I'm unsure about how sonar works, but it sounds like we're finally starting to see what's down there.
00:51We are.
00:52So what have we found?
00:52We've found a lot of things. We've found thousands of new species, we've found deep-sea trenches that are deeper than Mount Everest is tall, and we've found hidden volcanoes.
01:01So there's a whole world down there that we just don't know about.
01:03Yes, and we're finding a new species a day. We've also found a lot of shipwrecks and a lot of lost treasures.
01:08So there's a lot of things down there that we just don't know about.
01:11It's a great reminder that our planet is full of mysteries.
01:14So what's the big takeaway from all of this?
01:16I think the big takeaway is that we're living on a planet that's full of mysteries, and we've only explored a small part of it.
01:21It's a great reminder of how much we still have to learn.
01:24So, Charles, it feels like we've covered the most interesting facts about the ocean.
01:27We have. So thank you for being with us today.
