Interesting facts about the oceans


Hello dear readers of the website. It is probably no secret for you that most of the surface of our beloved Earth is covered with water. To be more precise, that’s a whopping 71%. But, if you know this, then you might not know that sea waves can travel at a speed of more than 800 km / h. Or, you also might not know that it contains millions of tons of gold. Or the fact that scientists have better studied the distant Mars than the oceans on our home Earth.

And this is not all that we can tell you about the oceans. In today’s publication, we have collected the most interesting facts about these largest water bodies on the planet.

# 1

Most of the planet is in absolute darkness. Why? The thing is that the average depth of the oceans is 1225 meters. At the same time, the sun’s rays can reach a depth of only about 75 m. Therefore, all the water located below this mark is in pitch darkness. Since water makes up a large part of our planet, it turns out that it is constantly in absolute darkness.

# 2

The lowest known point on Earth, called the Challenger Abyss, is 11,034 meters deep. It is located in the Mariana Trench in the western Pacific Ocean. To understand how deep it is, if we could take Mount Everest and place it at the bottom of the abyss, then there would be more than 1 km above the mountain to the surface of the water.

The Pacific Ocean is the world’s largest body of water. It occupies 1/3 of the surface of our planet. It contains approximately 25,000 islands (more than the total number in the rest of the oceans combined). Almost all of these islands are located south of the equator. Its area is 178,684,000 km².

It has lakes, rivers and even waterfalls. Sounds amazing? This is actually the case. What’s even more surprising is that these underwater lakes and rivers can vary greatly in size, ranging from a few meters to several kilometers wide.

The largest known waterfall on our planet is located between Greenland and Iceland. And yes, it is located underwater. Its dimensions are about 160 km, and water falls 3505 meters from the Greenland Sea into the Irminger Sea, carrying about 5,000,000 cubic meters of water every second.

The oceans are literally teeming with life. There are completely different creatures here, from single-celled organisms to huge blue whales. The ocean is a very complex ecosystem, home to fish, octopuses, squids, eels, sharks, dolphins, crustaceans, etc. And the list goes on and on.

According to the calculations of scientists, about 94% of all living creatures on the planet live in the oceans and seas.

In addition to existing species, scientists discover about 2,000 new species of animals in this aquatic ecosystem every year.

# 6

When you swim on its coast in summer, the water seems warm and very pleasant to you. But in its deepest parts, the water temperature can be almost minus (about 2-4 degrees Celsius). At the same time, the water is not very cold in all deep areas. For example, in areas where hydrothermal vents are located, the water temperature can be 400 degrees Celsius. But why isn’t it boiling? It’s all about the strong pressure, which does not allow the water to boil.

# 7

In the introduction, we already mentioned that there is a lot of gold here. In fact, about 10-20 million tons are scattered there. Gold is dissolved in his water. Scientists estimate that 1 liter of seawater contains 0.000004 mg of gold. There is it undissolved at the bottom of the ocean, but its extraction is unprofitable.

No. 8

When it comes to volcanic activity, no one can compete with the oceans in this regard. In fact, about 90% of all volcanic activity on Earth occurs in the ocean, and the largest number of active volcanoes is located in the South Pacific Ocean. This area is called the Pacific Volcanic Ring of Fire. There are 328 active volcanoes out of 540 known to mankind in this zone.

If we talk about inactive volcanoes, then there are about 1 million of them under water.

No. 9

Scientists estimate that about 7 million tons of plastic are dumped into our oceans every year. What’s even more dangerous is that these polymers affect all kinds of ocean life. Researchers at the University of California, San Diego claim that fish in the North Pacific swallows 12,000 to 24,000 tons of plastic annually. Microplastics even penetrate our bodies when we eat sea fish, shrimp, mussels, etc.

Scientists also believe that by 2050, the volume of plastic in the world’s oceans may exceed the volume of all fish living there.

No. 10


We know that trees give off oxygen. However, did you know that oxygen is supplied not only by trees, but also by the oceans? Scientists estimate that they give us about 50-80% of all the oxygen on Earth. This is due to photosynthesis produced by marine plankton, algae and some bacteria.

No. 11

Probably, each of us would like to find a lost pirate map, which contains instructions for finding the once buried treasure. And if maps are difficult (or even impossible) to find, then finding treasures at the bottom of the ocean is easy. Scientists estimate that there are about 1 million sunken ships at its bottom (according to some other estimates, about 3 million). This count includes not only large ships, but all boats, yachts, etc., sunk in the 21st century.

It is also estimated that there are treasures at the bottom of the ocean, approximately $ 60 billion.

No. 12

The most remote part of the ocean is called Point Nemo. The three nearest points from Point Nemo are located at a distance of at least 2688 km. This point was calculated using computer simulations in 1992.

No. 13

We know the water is clear, but why is the ocean blue then? The thing is that the water in it works like a light filter. It absorbs the sun’s rays of the red spectrum and leaves the blue and green colors that the human eye sees.

That’s all, dear readers. Thank you for choosing our site for useful information.
