There is approximately 71% water on Earth, but despite this, a large part of the ocean depths is still hidden from human eyes and technology. According to scientists, reaching the deepest places of the ocean is still very challenging. These areas are not only difficult in terms of atmosphere and pressure, but the aquatic and geological structure here is also full of mysteries. For this reason, this unseen world of the ocean still remains a mystery to humans.
Ocean depth and human access
Till now only 20% of the ocean has been explored, 80% is still unknown. The pressure and temperature from the surface of the sea to the deepest part is unbearable for human life. For example, the Marina Trench, which is considered to be the deepest trench on Earth, has a depth of approximately 11 kilometers. The human body cannot bear the pressure of water at such a depth. This is the reason why human exploration and research has so far been limited to surface water and small depths.
secrets of the sea
There are many such secrets hidden for humans in the depths of the sea which have not been revealed yet. Countless strange and wonderful creatures are found here. The creatures living in the deep sea are often lightless and their body structure is also unusual. Apart from this, there are unknown sea mountains, craters, and volcanic structures present in the ocean floor, which scientists have not yet fully understood.
There is abundance of minerals and natural resources in the deep parts of the sea. Metal, gas and rare minerals are found in many places. Apart from this, remains of old ships, inscriptions of ship accidents and traces of human civilization may also be hidden in the depths of the sea. This is why the ocean has always been a center of attraction for scientists and researchers.
technology and discovery
In recent years, technologies like sonar, robotic submarines and underwater drones have helped in revealing the picture of the deep sea. Despite this, due to the vast expanse of the ocean, a large part of it is still undiscovered and unknown. Scientists say that in the coming decades, new technology and space research can provide more information about these mysterious depths of the ocean.
