More than 40% of the planet's population lives within 100 km from the ocean, but our sea knowledge is still scarce. People easily enter the space rather than withstand the crushing pressure of the sea abuse. And although we often learn something new, some puzzles are still out of our understanding. Scientific portal speak About the secrets of the ocean, thereby scientists are beating.
Why whales killed white sharks
Something strange is happening in South Africa. For nearly 10 years, the corpse of white sharks with tear liver has been washed on the country. It indicates that shark mortality rates increased by the frequent appearance of a pair of male killing. And in 2022, they were arrested in the process of hunting white sharks.
Except for whales turning sharks so that they fall into a state of motionless, then they tore their stomachs to enjoy the fat liver. Scientists worry that this behavior can affect the sophisticated ecosystem of the area: there have been signs that white sharks are running to deal with those attacks. But why did the killer suddenly began to hunt them? Typically, these predators take a boat to South Africa to get dolphins, and only in 2015-2017, they started hunting sharks.
Where did the water come from the ground
The Earth 70% is covered by an ocean with an area of 360 million km and an average depth of 3,682 meters – the largest living environment on the planet. And although science knows that the Earth was formed about 4.5 billion years ago, no one could say exactly where all the country came from.
There are two potential theories. It is claimed that our planet is formed in the Cosmos area, where not only minerals, but also, in any form and water. And the second assumption that our galaxy corner is too hot for the existence of water and it appears on the planet after forming the earth thanks to other bodies in the solar system.
Who (or something) created the Yonaguni monument
Not far from the Jonaguni coast, the south of Nhat Ryukyu Island, the seabed is a strange formation of the rocks. Diver Kinatiro Aratak was found to be discovered in 1986-I want to find a convenient place to observe sharks.
An unusual monument is a pile of perpendicular sandstone blocks connected by parallel hanging racks. He also has a spiral staircase and a strange engraving, because some believe that the monument is a monument filled with ancient culture.
No one knows how Yonaguni's monument appears. Some people believe that it is a human -made: supposed to be an ultrasonic study that has confirmed that it was created about 10,000 years ago. Others are sure that he is naturally established. Many rocks in this area are likely to completely break vertically and horizontally, even on land. And some engraving may be nothing more than scratches on the sandstone surface.
Where strange sounds emanate from the ocean
The ocean is an unexpected noisy place. Human activities, animal calls, volcanic shocks and seismic changes create a rich underwater sound. But some scientists misleaded.
In 1991, for the first time, the Board of Directors of the National Ocean Research and the National atmosphere recorded a curved version of Muslims – an unknown sound that existed to this day. He only appeared for a few seconds and came from the point between New Zealand and South America, usually in the spring and autumn. Another noise, Ping, originated from the Fury-end-hekla strait in the Northern Pole of Canada. And BluP Blup is the most unexpected. It was first discovered in 1997, and sound waves reached hydrophones at a distance of thousands of kilometers from each other in the Pacific.
What is the origin of these sounds? GF Lovecraft's fans hope that Ktulhu is actually located in the ocean floor, but no. Scientists have found the reason for at least one of these noises. The more BluP, the sound of a iceberg from a giant glacier.
What happens at the bottom of the ocean
When talking about the sea and the ocean, most people imagine the waves and the surface of the water, but deep below them lying on the bottom of the sea – a quite mysterious place. Although humans have drawn a seabed card using satellite data, that information does not take into account the details of the terrain. It does not see the underwater gangs and historical artifacts – for example, submerged ships.
Good news is that scientists are actively working to fix this error. As part of the Beabed 2030 project, experts from around the world plan to create an updated ocean bottom map using modern high -resolution technologies. Yes, at this time (as of June 2024), they only handle 26.1% of the entire ocean area – until the end of completion. But the completed card will allow us to learn more about ocean current, climate change and tsunami.
