The Ocean Wonderopolis

What lives underneath...?

Exploring Earth's aquatic ecosystem!

According to National Geographic, over 60% of our planet is covered by water more than a mile deep. The deep sea is the largest habitat on earth and is largely unexplored.


Those of us who have been lucky enough to see the ocean in person can attest to its enormity and fascinating lure of deep blue (or green) water's begging to be discovered. Whether you have traveled to the Atlantic, Pacific, Indian, Southern (Antarctic) or Arctic Oceans some may wonder just what is lurking under the surface...way under the surface!

Just How Deep Are We Talking?

The ocean is deeper than Mount Everest, at 8,850 meters (29,000 feet tall).

According to NASA (2015) at that depth, the temperature is always just above freezing, the pressure is more than 1000 times what it is on the surface, and many bottom-dwelling fish and invertebrates call it home!


Other fun facts about the sea!


-Under the ocean, you can find many mountain ranges.


-One large Antarctic iceberg could supply all of Los Angeles' water supply for 5 years!


-If you were an alien landing on Earth, you would have about a 60% chance of landing out of sight of land.


-Seven million years ago, when geological forces lifted the Straits of Gibraltar and blocked the flow of Atlantic Ocean water into the Mediterranean, the Mediterranean Basin was completely dry! And in some places its bed lies 4,000 meters (13,000 feet) below sea level.
