We have explored forests, deserts, the Arctic, and even the moon. But one place is still largely unauthorized. Our oceans cover about 70% of the Earth's surface, but we know much more about the geography of Mars than what is at the bottom of the ocean. But that could change. People all over the world are finally seeking to reveal the secrets of our deep seas for both scientific and economic benefits. So, how close are we to fully mapping the ocean? People have been moving to the oceans for thousands of years to find out how deep our oceans are. It basically involves tying the weight with a long rope and throwing it on the side of the boat. The fact is that we discovered the deepest part of the ocean, the Mariana Trench. Since then we've clearly evolved with our technology, and in fact already used satellites to map the entire ocean. kind of. The way they do ocean satellite mapping, they use ultimatums. Because a satellite is passing over an orbit, if the height of a rock, or a mountain, or something that is below sea level, an increase in gravity actually causes it to rotate around the top.
Some cause water to accumulate and they can measure it at different sea level levels. By using some algorithms and processing this data, they can actually get a reasonable representation like here. But decent is not so good. Satellite mapping gives only about 5 km of sea floor resolution, meaning we can see features and objects over 5 km. In this context, most of Mars is mapped at 6m and almost all Venus and 100% of the moon are mapped at 100m. Less than 10% of our oceans, and perhaps close to 5%, are mapped to this detail. It's really frustrating for a marine organism, really frustrating for anyone thinking about doing business on the oceans, managing the oceans, thinking about our needs from the future of the oceans. How can we change the use of the ocean by having a detailed map in the dark? This will help with safety, such as charting potential hazards that could land the ship. This can lead to more accurate weather models, better understanding of tsunami risks and better weather forecasts. This will help in laying sea cables, fiber optics and pipes. However, it can also help to exploit the natural resources of the sea, such as the precious metals that were used to make your cell phone.
But having a detailed map will help us understand how to protect the sea when the inevitable rush for further exploitation begins. Part of the compensation of the International Maritime Authority, which is responsible for overseeing coastal seabed mining, is to set up sites for special biological interests that will not be mined and relocated. Will keep on, in places where it is important to them. Knowing the matter of biodiversity and the work of the ocean, it is necessary to know what is there ... So you are not mine, for example, make a rain forest and put your protected area in the desert Well, mapping the ocean can be a double-edged sword. On the one hand, people are making geological and biological discoveries along the way, trying to map the ocean to help understand and protect it. Others are trying to understand and exploit it, potentially harming the sea, but the two groups will work together to achieve a goal that benefits both sides. his. How to manage what you don't understand We can map things like manganese nodules, which have the potential of copper and nickel and cobalt. We rely on sea mapping before they find any type of oil before they map both the surface of the sea and the surface of the sea, and in this case, we need mapping. Sources are going to get a full understanding here and then what can happen. Set up proper management methods so if everyone wants this map then why hasn't it been done yet? Well, it will cost a lot of money. And it will take a long time. Probably a maximum of 200 ships a year. So with the help of modern technology, it would take 200 years or 200 ships a year for a ship to map the whole ocean. The question is price. We estimate that mapping the entire ocean at the appropriate level of resolution would cost three billion dollars and you would say, "Wow, who would ever spend three billion dollars to map a planet?" "And I point to the fact that we have sent missions to the moon that cost 600 600 million or more, and that lunar mapping is much better than mapping our planet. We have sent many missions to Mars. Each of these missions is worth between two and three billion dollars. And that's how we want to do it.
One way to reduce costs is to make it faster, and the good news is that there is a plan. With the weight on the side of the boat, the acoustic waves he used changed. By sending hundreds of beams like lasers into the ocean and measuring how long it takes to return, scientists can more accurately map the depths of the ocean. We are trying to develop techniques to speed it up, so that it can be done quickly. And this work will be done with autonomous ships, ships that will be more efficient that you do not need to have a crew and have to send out autonomous vessels for months at a time and collect them data. Let's go out and do it autonomously to get the drones out, this is a new project that is currently being developed, but it is still in its infancy. The amount of drones that will need to go out to perform this is something they are still working on. So yes, one day in the near future our seas could be prepared with the help of drones or less ships than the crew in the ocean, crossing the planet, collecting and sending data in a 3D map of our oceans. Will change What is another obstacle we need to know now, what to do with all this data? There's also the big challenge of trying to collect and synthesize this data on a large scale; collecting data on 500,000 hard drives and 500,000 vessels is one thing, but you have to put them all in one place. Required. And a group called Bold, Seabed 2030 is leading the fight. The collaboration project between the Nippon Foundation and the GEBCO aims to collect all bathroom data and create the world's first highly useful mapping map by 2030. Surprisingly, whenever we go out in unknown waters for a map, we find out. Something we didn't know about. It's the kind of discovery and discovery that really drives me, at least in terms of marine mapping. And it is their passion, along with their hard work, that has enabled those in society to work from the ground up with the 2030 deadline approaching. They can certainly use more resources if they get close to hitting that goal, but I'm going to go ahead and make the least wish, I hope they're right that we map the seas. Will 2030. I think the global initiative to do that by 2030 is going to go a long way. It's going to depend on evolving technology and the combined efforts of different players, but I'm optimistic and I think it will happen someday. We need a detailed map of the ocean to better understand the ocean, and to do that we need people, ships, modern technology, global cooperation and of course money. So, how close are we to mapping the whole ocean? Well, all eyes are on the seabed 2030 and their goal is to create a complete, public map by 2030. We are going to give him our closest job. This is a very, very ambitious goal. I'm not sure we'll get 100 percent there, but we're definitely going to make some progress. So our goal is to have all these images by 2030.
