Fascinating Things you Probably Didn’t Know about the Ocean

There’s a lot we don’t know about the ocean, and it will be fascinating in the future to fill in the blanks and close the knowledge gap, learning more about what lies beneath the surface of the majority of our planet.

Yet what we do know about the ocean is just as fascinating! We literally are only beginning to scratch the surface, yet what we have discovered so far is mind-bending.

Being major ocean geeks and lovers, we have decided to compile this post with some of the most interesting and awesome facts about our mother ocean.

Fascinating Facts about the Ocean

The ocean’s depth varies from location to location, but at its deepest point, the Mariana Trench in the Pacific, it is 10,994 meters. Yet, the light from the sun only penetrates to a depth of 1,000 meters!

Can you imagine what lies in the deepest, darkest parts of our ocean? It’s somewhat scary to think about, but it also invokes curiosity and wonder. We can’t wait to find out as more and more brave oceanic explorers take the plunge and bring back knowledge of underwater worlds.

What will we find next? Nobody knows, and we’re already at a loss to explain some of what we DO know is there.

The ocean holds 97% of water on earth and covers 70% of our planet’s surface. It’s unthinkably big, and if you take the water frozen in the ice caps and glaciers out of the equation, only 1% of the earth’s surface water is NOT in the ocean.

All that water leads to a lot of weight and pressure. At the deepest point, the Mariana Trench again, the pressure is 1000 times greater than at the surface. Imagine that if you can.

Many of the probes sent to the bottom have simply collapsed under this immense pressure, like an empty can of coke under a human boot. When James Cameron went solo to the bottom of the trench, the creaks and cracks could be heard even though his sub was made of specialized metal alloys made to withstand the pressure.

There are also some insanely scary looking creatures down there, living in the shadows. A giant sea squid, for example, has been discovered with a length of 60 feet. Think about that. Recall any 6-foot men you know? Now multiply that by 10. We’d hate to encounter that on a deep sea dive!

Overall, these things are just a tiny glimpse of what lies beneath. We are constantly learning more about what goes on down in the bowels of our mother ocean. The truth is, we have no idea. We know more about the planet Mars than we do about our own ocean.

What other fascinating facts do you know about the ocean? What creatures have you learned of? What unexplained mysteries have you encountered, and what do you think best explains them?

5 Threats Our Mother Ocean Is Currently Facing

Our mother ocean is the biggest habitat for life on earth.

It has a vital role in keeping our planet healthy but it is facing a lot of ever-growing threats.

In this article, we will be taking a look at the 5 biggest threats to our oceans and what we can do about them.

1. Overfishing

This can be simply stated as catching too many fish for the ocean to support. We are depleting the number of fish in our oceans and populations can’t recover on time.

Over-fishing our ocean

Humans are not content with catching fish close to the shore, so we have gone further and exhausted species that might soon go extinct. Industry and greed are the culprits here and far too many of these fish are wasted.

2. Climate Change

Everyone knows about it by now and it’s affecting the ocean severely.

In 2013, it was reported that temperature in the ocean rose by more than 0.1 degree Celsius each decade between 1970 and 2010. The warming of the ocean is causing some habitats to die, other species to relocate to new areas ,and the sea level to rise.

3. Ocean Acidification

This happens because of excessive CO2 dissolving in the sea forming carbonic acid.

Acidification damages many ocean species that use calcium carbonate to form their skeletons and shells. Ocean acidification also affects the whole ecosystem like the coral reef which is dependent on the formation of calcium carbonate to build reef structures which in turn provide homes for other organisms.

4. Pollution

Environmental enemy number one, pollution can DESTROY marine life and damage the marine environment.

A large quantity of waste is thrown into the ocean including plastics, oil, sewage, sediments and toxins. This can create dead ocean zones where sea dwelling organisms are suffocated due to low oxygen in the water. The biggest dead zone can be found in the Gulf of Mexico, ‘coincidentally’ the site of much oil drilling.

5. Habitat Loss

Habitat loss happens when a natural area is taken over by humans for their own use.

Pollution soon follows, causing the death of coral reefs, destroying the ecosystem and depleting the populations on living organisms.

Coastal development, trawling, and aquaculture are some of the most common human activities that devastate marine habitats which are essential to keeping the ocean healthy.

However, there is hope!

Although we may feel that we cannot do anything or can only do so little to help save our mother ocean, let’s just keep in mind that it doesn’t take much to turn the tide and it only takes one positive step to encourage the change that we want.


Let us start by sharing and talking about this with other people.

Being efficient in our energy usage and waste disposal can also make a big difference in conserving our ocean.

Lowering our carbon emissions will help slow down the warming and acidification of our oceans, too.

Knowing where the fish we eat are from and if they’re from sustainable sources is also one way in reducing overfishing.

A small change in our lifestyle can actually make a big difference. If everyone makes a small change, that leads to a massive change!

It’s not too late to save our mother ocean. Knowledge is power. Empower your friends and people you know by sharing this article today.

The Mariana Trench – The World’s Deepest Point

Lying to the east of the Mariana islands in the Western Pacific ocean, the Mariana trench represents the deepest point of the world’s oceans.

A colossal 2,5000km long and 69km wide on average, the trench has been seen and explored only a few times by the world’s most daring adventurers.

Very little is known about the Mariana trench, other than that the pressure on the seabed surrounding it is enough to crush a London bus like a can of beans under someone’s foot. The pressure in the water column above the trench floor can reach 1,086 bars, 1000 times greater than atmospheric pressure at sea level.

At its deepest point of 10,994 meters, in a small valley known as the Challenger Deep, nothing can survive.

Only two people have ever descended into the Mariana trench successfully. The first was Jacques Piccard and Navy Lt. Don Walsh, in 1960. No photographs were able to be taken at the bottom due to the extreme temperatures. The descent lasted 5 hours in total.

More recently, in March 2012, world-renowned movie director and adventurer James Cameron descended solo into the trench, making a documentary called James Cameron’s Deepsea Challenge. This gave, for the first time, a glimpse into what it is like at the deepest known point of the oceans.

Yet even after this most recent descent, less is know about the Mariana trench than is known about the surface of Mars. The earth’s oceans and deepest points are fast becoming a powerful draw for explorers, adventurers, and scientists keen to learn more about what goes on in the deepest depths of our planet.

Expect deep sea exploration to continue and the number of expeditions to grow in the coming years. What lies beneath nobody truly knows, and as long as that remains so, curious men and women around the world will be steadily working to close that gap in knowledge.

What other deep sea exploration projects do you know of? What was discovered? We’d love to hear from you in the comments below.
