It is estimated that 97% of the world’s water is found in the oceans. Because of this, the ocean has a significant impact on climate, temperature and food resources of humans and other organisms. Despite its size and impact on the lives of every living thing on Earth, the ocean remains a mystery. More than 80% of the ocean has never been mapped, explored or even seen by humans. A much higher percentage of the surface of the moon and the planet Mars than the ocean floor itself has been mapped and studied.

Although there is more to learn, oceanographers have already made some amazing discoveries. For example, we know that the ocean consists of towering mountain ranges and deep valleys known as trenches, just like those on land. The highest peak in the world – Mount Everest in the Himalayas – 8.84 km (5.49 miles) high – does not break the water level if two of the deepest are in the Mariana Trench or the Philippines. Parts of the ocean

The Atlantic Ocean, on the other hand, is relatively shallow because large parts of the seabed are made up of continental shelves – parts of continents that extend to the far seas. The average depth of the whole ocean is 3720 meters (12200 feet).

It is not clear how many different species of ocean are called home. As many marine ecosystems suffer from rising sea temperatures, pollution and other problems, some oceanographers believe the number of species is declining. Nevertheless, many positive surprises await oceanographers in the coming years. More than 90 percent of the ocean species may not have been discovered yet, with some scientists estimating that there are between a few hundred thousand and a few million more. Currently, scientists know about 226,000 species of oceans.

Further acquaintance with the sea floor and the rest of the ocean is the interest of Marcello Callisti, the discoverer of National Geographic. She is a biorbatician who is developing an underwater exploration device that uses “foot movement” and is inspired by the way an octopus moves underwater. Her remote goal is to design robots that can detect depths that are difficult for humans to access.

Because the ocean is so vast, there are many future oceanographers from all over the world to explore and discover.
