7 Interesting Facts About The Ocean

Hello everybody and welcome to a new article. Today I will be sharing 7 interesting facts about the ocean. The ocean is filled with mysteries unknown to humans. Who knows what is hiding in the cold deep dark below. Mermaids? Megalodon? Atlantis?

Oke, I might be letting my imagination loose for a minute, so let’s get started with 7 interesting facts about the ocean.

1. There are More Treasures on the Bottom of the Ocean Than in all the World’s Museums Combined

It is estimated by the United Nations Educational, Scientific, and Cultural Organization that the oceans are hiding 3 million shipwrecks.

That are a lot of shipwrecks and not surprising if you look back in history. Humans have sailed the seas for centuries and not only can you find shipwrecks in the ocean. You can also find airplanes, submarines, and other ways of transportation that went under from wars, pirates, and accidents.

Because a lot of those wrecks are hundreds of years old if not older as in thousands of years. The amount and value of all those treasures, artifacts, and historical information is worth more than all the museums in the world together.

Especially cargo ships, like Spanish galleons that used to transport gold and jewels. However gold and jewels were not the only kind of merchandise being transported by cargo ships. Other variations of merchandise were also shipped overseas, like silver, copper, tools, weapons, and many more.

I can hear you thinking, well then go down there and get all that treasure. Well, it is not so easy. Because less than 1% of all the shipwrecks have been explored. It takes a lot of time and money to locate the shipwreck and actually go down in the deep dark ocean.

Some of the famous shipwrecks are:

  1. The Titanic
  2. The Spanish Galleons
  3. The Greek Antikythera

2. Coral Creates Their Own Sunscreen

Pretty awesome but how? Good question. Because coral is vulnerable to sunburn, too much exposure to sunlight can damage the algae which are living inside the coral, and algae is a source of food for the coral.

So in order to protect the algae, the coral fluoresces and this creates a compound called proteins that protects the algae. Like sunscreen does. This is not only great for the coral and algae but it is also beneficial for the fish that eat the coral.

How awesome is that, and what makes it even more awesome is that there is a possibility it could be beneficial for people as well. A study from Paul Long of King’s College in 2011 discovered this amazing phenomenon.

3. Where Does the Oxygen We Breathe Come From?

You probably will say that the Amazon Forests are the lungs of the Earth but that is actually not true at all. As a matter of fact, scientists believe that the ocean creates between 50-80% of the world’s oxygen and absorbs over fifty times more carbon dioxide than our atmosphere does.

The rain forests produce approximately one-third of the world’s oxygen (28-34%), and approximately 2% comes from other sources on the planet. If you would like to read a more detailed calculation about this subject then I suggest an article from Yadvinder Malhi.

4. Great White Sharks Underwater Café

A study led by researchers from the Hopkins Marine Station at Stanford University discovered that white sharks migrate in the winter and spring to a remote part of the Pacific Ocean, between Hawaii and Baja California. These researchers named this specific spot the White Shark Café.

After using satellite tracking tags the researchers discovered that the white sharks came from various places along the North American coast and hang out for months in the White Shark Café before the white sharks would swim back to the coast in the fall for seal breeding season which is a food source the white sharks just love.

During the daytime, the white sharks dive to the edge of complete darkness at 1,400 feet (426.72 Meters). While at night they come up closer to the surface where the water is warmer and more productive.

Even though the researchers think that the white sharks dive to the edge of darkness to hunt for larger prey. The researchers are not sure why the male white sharks travel in a V-shape pattern as many as 140 times a day. It could be mating or hunting for prey.

If you would like to learn more about the White Shark Café you can. Because an amount of information can also be found at the Voyage to the White Shark Café.

5. The Loudest Sound Ever Recorded Came From an Icequake

And it would take 15 years before Scientists from NOAA’s, The National Oceanic and Atmospheric Administration would find out the origin of this sound. Researchers discovered this sound in 1997 at the Southern Pacific while researchers were listening for volcanic activity underwater with microphones.

These underwater microphones, called hydrophones are located all over the Pacific and cover an area of more than 2000 Miles (3,219 Kilometers).

Many theories have been going around about what this sound could be. Speculations started and people started wondering if this sound could be a giant squid perhaps a whale, or something living in the deep dark ocean that has not been discovered yet?

Because it was such a unique distinguished sound it became known as “The Bloop” and this sound was coming from an icequake breaking apart an iceberg from an Antarctic glacier and that cracking noise reached all the way to the microphones of the researchers.

6. The Largest Waterfall in the World is in the Ocean

Which is located between Greenland and Iceland and goes by the name, the Denmark Strait Cataract. At the bottom of the strait, there is a sequence of cataracts that begin 2,000 feet (609 Meters) under the strait’s surface and plunge to a depth of 10,000 feet (3048 Meters).

The tallest waterfall above sea level is the Angel Falls in Venezuela with a height of 3,200 Feet (975 Meters). Which is three times shorter than the Denmark Straight.

To make the Denmark Strait even more impressive. The flow rate of the Denmark Strait waterfall is 50,000 times more than the Niagara Falls.

Let’s get to the last fact of 7 interesting facts about the ocean.

7. The Highest Mountain Under the Ocean is Higher than Mount Everest

With an amazing height from the ocean floor, Mauna Kea in Hawaii measures 33,500 feet (10,210 Meters), and being nearly a mile higher, Mauna Kea pushes Mount Everest aside.

So does this means that Mount Everest is not the highest mountain on Earth? Well, it depends on how you phrase the question in all fairness. Because you have three potential candidates that can claim the crown. Mount Everest, Mount Chimborazo, and Mount Mauna Kea.

7.1 Two Facts in One

It really depends on where you start with measuring the height of a mountain. When you measure above sea level then Mount Everest is the highest mountain in the world.

With an impressive 29,029 feet (8,848 Meters) Mount Everest holds the crown over 14 mountains on Earth that are 26,246 feet (8,000 Meters) tall or higher. Called the “Eight-Thousanders“.

Mount Chimborazo in Ecuador is the highest mountain in the world if you start measuring from the center of the Earth.

With 21,522 feet (6,560 Meters) Mount Chimborazo’s peak is 6561 feet (2000 Meters) farther away from the center of the Earth than Mount Everest. Which also makes Mount Chimborazo’s peak the closest point to the sun.

Last but not least mount Mauna Kea in Hawaii is the highest mountain in the world measured from the ocean bottom with a massive height of 33,500 feet (10,210 Meters). Therefore beating Mount Everest, and Mount Chimborazo.

Mauna Kea means in Hawaiian “White Mountain” and is an inactive volcano. The mountain got its name because mount Mauna Kea’s peak is often covered in snow during winter.

The peak of mount Mauna Kea is 4,207.3 m (13,803 ft) above sea level, and therefore if you measure from above sea level then mount Mauna Kea is not higher than Mount Everest.

If you like to see mount Mauna Kea live on webcam then you actually can at Mauna Kea Weather Center.

The ocean is full of interesting facts. Thank you, everybody, for reading my article about 7 interesting facts about the ocean. Let me know in the comment box if you thought it was interesting.


  1. Hey Nicole. I was totally engaged with your article. The point which interested me the most was the first one which talks about treasure. I had no idea that so many historical artifacts resided at the bottom of the ocean! A few years ago some friends and I were joking about quitting our jobs and starting a treasure hunting company. Had we known that so many shipwrecks lay at the bottom of the ocean we probably would have followed through!

  2. Holy cow! Very informative and love the videos too!! Didn’t know there was much under the ocean, as I was paying more attention to fish tanks above ground lol. Thank you so much for all of this 😀

  3. Wow , this article was really educative and also a huge eye opener as well, I really enjoyed it and the biggest shocker was the 7th fact that states that the tallest mountain in the ocean is taller than mount Everest. This was a very fun piece. I even shared it with my friends because I know they would love it as well

  4. I love this post!  I like all 7 interesting facts you posted about the ocean.  My grandson is fascinated with sharks.  I have always wanted to see the rain forest, on my bucket list.  It’s amazing how you stated 1/3 of the worlds oxygen comes from the rain forest.  The other thing I found amazing is you stated the largest waterfall is in the ocean.  How can that be?  It must be amazing to see.  Beautiful pictures to show what it looks like.  Thank you!

    • Thank you for reading 🙂

      The waterfall is formed by the density difference of the water masses on both sides of the Denmark Strait, one side being colder than the other side. Because of this difference, when the two masses meet along the top ridge of the strait, the colder, denser water flows downwards and underneath the warmer, less dense water.

  5. Well well, this is quite an interesting and very much engaging article. I can only imagine the treasures that are buried deep under the oceans. Clearly there is a lot to uncover with the right tools and the capacity to dig into the mysteries. That’s a good collection of interesting facts. I also believe there could be quite a good number of undiscovered creatures that lives deep under the oceans. The last part is just my imagination going wild lol. Excellent work for putting together these interesting facts.

  6. I love your site. I chose this article to look at because I love the ocean. I love any form of water, but the ocean is my favorite. Which is one reason I live in CA. I used to scuba dive. The ocean is a fascinating place. Did you know that not only is human blood mostly water, but the watery portion of blood, the plasma, has a concentration of salt and other ions that is remarkably similar to sea water? Isn’t that cool? I learned a lot from this article. I especially enjoyed the section on the Great White. Barbara

    • Thank you for the kind words, I am glad you liked my article. And I did not know that the portion of the blood is similar to sea water, pretty awesome.
