1. The world’s oceans contain almost 20 million tons of gold.

But before you grab a snorkel and some goggles…unfortunately, it’s not worth diving for this maritime treasure. First of all, a liter of seawater holds only a few billionths of a gram of the glittering precious metal, and second, despite intensive efforts, researchers have been unable to develop an effective method for filtering these tiny quantities out of the water.

 


2. 300 million people currently depend on seawater desalination plants.

Seit vielen Jahren beschäftigen sich Forscher bereits mit der Entsalzung von Meerwasser. Das Potential ist immens, denn die Ozeane stellen circa 97 Prozent des auf der Erde verfügbaren Wasservorrats. Der wissenschaftliche Erfolg ist extrem wichtig: Laut UNO haben etwa eine Milliarde Menschen noch keinen Zugang zu sauberem Trinkwasser, Tendenz steigend. Die Zukunft des Trinkwassers liegt demnach in modernen Technologien, die schnell, effektiv und günstig das Salz aus dem Wasser herausfiltern..


3. If we could store just 0.1 percent of the kinetic energy generated by the ocean’s waves, we’d be able to meet five times the planet’s current energy needs.

Kinetic energy is the energy that an object has because of its movement. In the ocean’s case, this is the energy of the movement of waves, produced by wind and weather at the water’s surface. There are many places where the wind is strong enough to ensure that waves are constantly moving. This in turn holds an enormous energetic potential that still remains untapped for the most part.


4. The deepest internet cable lies 8,000 meters under the ocean, between Japan and the United States.
A data highway that surpasses all others: The deepest internet cable, aptly named “Faster”, delivers an overall bandwidth of 60 terabytes per second along its entire 9,000 kilometers. It is the highest performance cable of its kind so far and runs from the US state of Oregon to the Japanese prefectures of Chiba and Mie.


5. 8,143 meters underwater, the deepest living fish has been discovered—and nicknamed “Ghost Fish”
It’s not exactly a beauty, but that doesn’t make it any less fascinating. The Ghost Fish is waxy, transparent and pale, has wing-like fins and grows to about 15 centimeters in length. Researchers discovered the animal deep in the Mariana Trench in the western Pacific. They filmed the new world record holder with special deep-sea equipment; the previous record depth for a fish was a mere 7,700 meters!


6. At the deepest spot in the ocean, the water pressure is the same as the pressure beneath a stack of 50 jumbo jets.
If you stacked 50 jumbo jets on top of each other, the resulting pressure would be equivalent to a measurement of 1070 bar, which is the unbelievable level of pressure occurring naturally deep down in the Mariana Trench. In 2012, another person almost made it down to the deepest spot in the Earth’s crust: James Cameron, the director of Titanic, dove down to 10,898 meters, exposing his deep-diving submersible “Deepsea Challenger” to the aforementioned pressure of 1070 bar.


7. By 2050, the amount of plastic in the ocean may be greater than the amount of fish.
Sad but true: A garbage truck full of plastic ends up in the oceans every minute. But it gets worse. Researchers at the Ellen MacArthur Foundation have calculated that the amount could quadruple in the coming years. There are already 150 million tons of plastic floating in the oceans.


8. In 2015, the offshore wind farms of Great Britain, Germany and Denmark were as productive as eight medium-sized nuclear power plants.
Right now, Great Britain has around 1,500 wind turbines, followed by Germany with 800 and Denmark with about 520. Taken together, the offshore wind farms of these three countries currently have an installed capacity of around 9,600 megawatts.
