3. Penguins can swim as fast as 25 miles per hour underwater.
5. If all the gold in the ocean was mined, there would be enough to give each person on Earth nine pounds.
7. Divers that travel one hundred feet underwater experience nitrogen narcosis, an effect that makes them feel drunk.
9. If all the ice found in glaciers and ice sheets melted, then the sea level would rise by roughly 262 feet (80m). That’s as tall as a 26-story building.

16. Nearly ninety-percent of volcano eruptions happen underwater.
“In the ’90s scientists discovered the largest known concentration of active volcanoes in the South Pacific Ocean. The area they discovered is roughly the size of New York state, It has 1,133 volcanic cones and seamounts. The scientists said that two or three could erupt at any moment.” —Smithsonian Ocean Planet
