There are three strange dangers in the ocean, what are these three strange ocean waves?

There are three strange "dangers" in the ocean, and these three weird ocean waves include offshore currents, eddies and mad dog waves.

Rip currents are rarely heard of, but if you have heard of some drowning incidents at the beach, most of them are caused by rip currents. Offshore current, the main terrible thing is that it is not particularly obvious, but the damage to people is very great, first of all, the wind blows to the shore from the sea, and the accumulation is formed on the shore This sea water will form a very strong backflow after leaving the waves, this flow speed is very strong, in a short period of time, it is possible to quickly drag people near the sea to the depths of the ocean, no matter how good the water is, there is no way to control this speed, In the event of an offshore current, it can be said that there is basically no possibility of returning. Offshore Drain: In any weather, any beach can happen and you may be dragged away by the offshore current.

There is also a mad dog wave is a kind of swell in the ocean, which often appears on the reef in the sea, especially when some fishermen are on the boat, they may encounter the mad dog wave, and it often occurs without warning, it is difficult to be prevented, and people will be swept into the sea in a very short time.

Most of the area of the earth is the ocean, and when you hear about the ocean, everyone will think that the sea is very beautiful and will make people feel relaxed, but many people will also have some fear when they see the sea, which is indeed the case, because now the sea is a secret that human beings cannot explore, and there are many unknowns that human beings cannot explore. The ocean is also a very dangerous place, because there is no way to observe the strait world with the naked eye, so human beings also want to dive into the sea through some other ways, but relying on current science and technology, there is no way to really explore the depth of the underwater world, and there is no way to know how big and deep the ocean is.

Finally, the ocean seems to be very calm, but there are many disasters that occur in the ocean every day, such as tsunami and waves, which may threaten people's lives.

There are three strange "dangers" in the ocean, and these three weird ocean waves are the murderous wave - mad dog wave, the ocean black hole - the ocean eddy, and the hidden master - offshore current.

These three weird ocean waves are mad dog waves, ocean eddies and offshore currents, which, if they occur, can engulf all ships and people in an instant.

Mad dog waves, giant waves of giant ships, tsunamis, tsunami land, ocean whirlpools, these are relatively terrifying marine phenomena.

The marine world has always been a highly mysterious place, the underwater world has always sparked our imagination, and scientists are interested in many equally shocking wonders of the ocean, which are also real. Do you know what are the mysterious phenomena in the sea? I have explained to you the top ten dangerous marine animals in the world before, and then I will reveal 10 mysterious phenomena in the ocean for you, if you want to know more, let's look down!

10 mysterious phenomena in the ocean

Lake Natrun in Tanzania is terrifying and magnificent, with its salt content and highly alkaline water making it petrified by any animal that dares to enter the lake.

Plankton is the first link in the marine food chain, and at night, a large number of plankton move through the ocean, creating an impressive light show.

It's a natural phenomenon that's hard to observe, and basically, they're like underwater tornadoes, known as the "icy fingers of death" because they kill any marine species trapped in the ice.

In Alberta, Canada, Lake Abraham is home to an interesting marine landscape. The lake bed releases methane gas, which is the result of the decomposition of organic matter. In winter, these bubbles are frozen in ice, creating an impressive natural landscape.

In 1995, strange circles were discovered on the seabed of Japanese waters, causing some controversy. In 2012, Japanese researchers finally solved the mystery with the help of underwater cameras, and it turned out that the puffer fish was drawing fantastic circular patterns with its fins to attract females.

From May to July, off the coast of South Africa, millions of sardines form huge spawns and begin to migrate north to breed. The "Sardine Run" is a real journey of survival of the species, which can be seen by satellite.

The Mariana Trench in the Pacific Northwest is the least visited place in the world for the simple reason that it is currently the deepest trench ever recorded, but it seems that the high pressure has not completely hindered marine life, as there are a large number of creatures still living there.

In 2011, Russian researchers finally arrived at Lake Vostok and found that it had been isolated for 14 million years 4 kilometers below the Antarctic ice, and that there were still creatures in it that were previously unknown to science.

Although weaker than a tornado and smaller than a tornado, the seaspout is quite impressive, a phenomenon that forms on a body of water, and the intensity of this spectacular meteorological phenomenon should not be underestimated.

The particular color of Lake Hillier in Australia remains a surprising scientific puzzle, and the bright pink color is supposed to be the result of the presence of microorganisms.

"Strange dangers" in the ocean:

1. Tropical cyclones

A tropical cyclone is a system of low pressure that occurs mainly over the sea surface (e.g., North and South Pacific, North Atlantic) 3-5 latitudes above the average equator. Indian Ocean) and is the most frequent disaster in the ocean.

Among them, typhoons and hurricanes are a kind of strong tropical cyclones that occur on the tropical ocean, and moving over the ocean will set off huge waves, and once they make landfall, they are likely to cause serious **.

Storm surge

Storm surge, also known as wind surge, storm tsunami, etc., is an abnormal rise and fall phenomenon of sea surface caused by a strong weather system, which can be divided into typhoon storm surge and extratropical storm surge, and the occurrence zone is mainly near shore.

Among them, the typhoon storm surge is ferocious, destructive, the sea water is abnormally high, and the huge waves will wash away human buildings, inundate farmland, people and livestock, which is a serious marine disaster that occurs along the ocean coast.

3. Tsunami

Tsunamis are massive waves triggered by seabed **, volcanic eruptions, seafloor collapses or landslides, and are a terrifying and devastating marine disaster.

In the open sea, due to the depth of the water, the waves are less undulating, so it is not easy to attract attention, and near the shore, the huge energy causes the waves to rise suddenly. It can travel at speeds of up to 600-1,000 kilometers per hour, and can instantly form a "huge wall of water" 10-40 meters high, which is invincible after pouring onto land, and the consequences are unimaginable.

4. Offshore currents

The rip current, also known as the "rift current" or "revolution current", is a narrow and powerful current in the form of a beam, more commonly known as a fault wave, with a current width of about 3-4 meters, which can turn rapidly from the sea to the ocean at a speed of 10 kilometers per hour.

It kills people unsuspectingly, and every year people are killed by "rip currents" along the coast. Even if the water is less than waist deep, if you encounter an offshore current, you are likely to be washed off the beach and swept into the sea in a short time.

Rip currents can occur in any weather conditions and are hardly foreshadowed, making them difficult for those who visit the seaside to notice.

5. Mad Dog Wave

Many people may be unfamiliar with the term "mad dog wave", which is a type of swell in the ocean, which often haunts reefs, headlands or seawalls in the sea.

Since the beginning of human voyages, sailors or fishermen have claimed that they have been attacked by a kind of super wave that "comes and goes without a trace", seems to have "stealth skills", and has also given a figurative name "mad dog wave".

For a long time, people thought it was just a legend or a once-in-a-century wave.

It wasn't until 1995 that the accelerometer and strain sensors on the Draupner offshore platform in Norway detected a huge wave with a crest nearly 26 meters higher than the surrounding trough, similar to the legendary "mad dog wave".

Only then did human beings discover that the "mad dog wave" is a real marine danger, which has aroused extensive discussion in the scientific community, and the "mad dog wave" has been continuously studied.

What is the phenomenon before the tsunami The surging waves, which rush over the sky in an instant, are a terrifying tsunami. The astonishing destructive power of a tsunami lies in the release of huge amounts of energy in an instant, when an undersea volcano erupts, or when a plate displacement caused by **, a large amount of seawater will be pushed into it.

Three or four waves of huge waves are pushed outward, the speed is so fast that it even exceeds that of jets, and the most terrible thing is that the ships on the sea may not feel the hidden danger at all, and it will not be until the waves rush ashore in an instant, and then they will form several floors of waves and mountains and seas, drowning everything on the shore. However, despite the difficulty of preparing for a tsunami, U.S. marine experts offer a few possible signs of a tsunami that may occur before it strikes: First, it is the occurrence of a tsunami scale of 7 or more**.

The second is that the sea water on the beach suddenly begins to recede rapidly. Thirdly, on the coast, there will be a sudden loud noise. Experts said that once these three signs appear, the public must immediately flee the scene, because the time to escape may only be as short as 5 to 10 minutes, the current domestic tsunami warning, the fastest, should be Kaohsiung University of Marine Science and Technology, according to Professor Zhang Guodong said, this time 18 minutes after the occurrence of the Indonesian **, Kaohsiung Haida through the connection with the international tsunami warning system, learned that the tsunami warning was issued, compared with an hour of the Meteorological Bureau, the speed is obviously much faster.

**Reference: Figure 1Source of the original picture of the true face of the tsunami:

If you know or see that a tsunami is coming, you should immediately move away from the coastline and do everything possible to go higher or run inward, when the tsunami occurs, the coastline will quickly move to land, which means that the tsunami is coming, and the people at the beach have only about 5 to 10 minutes to escape. Even if you don't escape until you hear the rumbling tsunami, you can escape in time. If you don't get there in time, you can have a better chance of surviving by clinging to a fixed object (such as a telephone pole or tree) around you.

Although there is no warning of the occurrence of the tsunami, the sliding friends can still be alerted to the abnormal phenomenon of the low tide of the sea, if you find that there are traces of fish and shrimp at the low tide of the sea, it means that it may be very dangerous, at this time you should escape to a high place, or stand in a place that is enough to support and fix on the ground to protect yourself. However, this time in the disaster areas of South Asia, many people have never seen a tsunami. Experts point out that if people are made aware of the warning signs of a tsunami, the death toll should be reduced, and so many people will not die in vain.

How to protect yourself when a tsunami strikes 1When playing in the water on the beach, if you find that the water level is falling rapidly and there is an abnormal low tide, you should immediately flee to a higher place 2When a tsunami hits, if you are on the coast, you should try to grab driftwood and other drifting objects to avoid drowning and wait for rescue. If you are on land, you should hold on to a fixed object such as a pillar to avoid being swept away by the waves

To improve your chances of survival, you need to learn to swim.

I am very scared of tsunamihelp, and the sea will suddenly swell.

So far, only 5% of the oceans have been explored, and 95% of the oceans are unknown. The ocean is not only vast but also mysterious, and amazing marine wonders often occur on the sea, follow in my footsteps to see what are the famous marine wonders in the world?

1.Red tide. Red tides, also known as red tides, are also known internationally"Harmful algae"or"Red Ghost"。It is a harmful ecological phenomenon caused by the explosive proliferation or high aggregation of certain phytoplankton, protists or bacteria in seawater under specific environmental conditions. "Red tide. ", which is an anomaly in the marine ecosystem.

It is caused by the explosive proliferation of red tide algae in the seaweed family under specific environmental conditions. Although it is harmful, the sight is still spectacular.

2.Chinese bicolor sea. Half of the blue sea and blue sky, half of the yellow sand and turbid waves.

Nantong Qidong Evergrande Bihai Yinsha, China's two-color lake. On one side of the dam, the sea is turbid and the sea is turbid; On the other side of the dam, the sea and sky are the same, and there is no end to it. A dam straddles the north and south, blocking the turbid waters of the Yellow Sea.

3.Bicolor Sea.

This is a bicolor sea in the Alaskan Sea in the Pacific Ocean, and they are two oceans where they meet. This strange phenomenon is caused by the difference in density, temperature, and salinity between the glacial meltwater and the water in the Alaska Gulf. Difficult to mix situations.

The light blue sea is glacial meltwater, and the dark blue is the sea with a very high salt content. When two bodies of water meet, a two-colored ocean is formed.

4.Blue striped icebergs.

The Blue Line Iceberg is short for the Blue Striped Iceberg. The blue line icebergs are incredible, and they are slightly more numerous than other striped icebergs. New ice is usually white due to the effects created by a large number of tiny bubbles.

The blue ice streaks are caused by fresh water poured into the cracks of the iceberg and freeze quickly after being poured in. The result is a beautiful blue stripe.

There are many strange scenes in the world, and there are too many strange scenes for us to dig deeper. Everyone also knows what bizarre ocean scenery is ** together.
