Some of the most sought-after metals and minerals on Earth lie deep — and largely untouched — in our oceans. Science and industry have been exploring those depths for decades. Here’s an overview of what we know. Here’s a simple fact to start: The oceans are huge. Oceans make up about 96.5% of all Earth’s water. There’s fresh water in the planet, in the ground or elsewhere on land in rivers and lakes — more than 70% of the planet is covered in water — and there’s more all around us in the atmosphere. But the oceans are simply huge. Our oceans remain some of the most under-researched parts of the planet. That’s one reason why there’s so much interest from both non-commercial scientists and those working in industry. And when it comes to deep-sea research, there are two main areas of interest: conservation and mining.
