What benefits deep sea exploration you don’t know?

The sea is not only the cradle of life, but also the home of life. 71 percent of the earth's surface is covered by ocean and only 29 percent by land. There are more than one million species of life on earth, nearly 90 percent of which live in the ocean. Underwater sea creatures are far more abundant in species and species than on land. What’s more important is that benefits deep sea exploration haven’t well known to human. Because five one-hundred percent ocean explored fields are just exploited.

1.How much does human being know about ocean and deep sea expeditions?

The average depth of the ocean is up to 3,680 meters, and the deepest Mariana trench reaches 1,1034 meters. Life exists in all depths of the ocean, whether on shallow ocean beaches or in the abyssal zone below 6,000 meters.The ocean provides about 300 times as much living space for living things as land and fresh water. These are primary deep ocean exploration facts we already know.

However, because of the great thickness of the water layer, the human understanding of the deep sea is not as good as that of moon surface, or even Mars! As so far, more than 400 space explorers go to out space,12 of whom aboard the moon, but only 3 deep sea explorers dive into Mariana trench.

2. How long deep sea exploration history is?

In 1942, Columbus rediscovered the new world. In 1519 Magellan embarked on his first voyage of exploration, and many other heroic navigators made great contributions to human understanding of the sea. During this time, fairly accurate maps, especially those maps on the edge of Europe appeared.

After that, explorers began to take interested in sailing seas and living things.Marine protozoa were first discovered in 1674 by A.van of the Netherlands. In 1777, Denmark's O.F. Miller used a microscope to observe plankton in the north sea. Since the second half of the 19th century, various countries have been racing to send out deep sea research ships and set up coastal biological research institutions. One of the most famous deep sea exploration facts in the 1870s (1872-1876) was that British survey ship "challenger" took three-year global survey to collect a large number of deep and medium creatures, published 50 volumes of magnum opus which recorded 4400 biological species.  

3. Benefits ocean exploration awaits divers and scientists to disseminate.

Just a year after the end of the Second World War, the first truly portable shallow water machine, the self-propelled underwater breathing machine,was successfully developed. Marine biologists observed Marine life in the natural environment underwater for the first time. History ocean exploration timeline once again changed.

Today, an increasing number of marine biologists apply the underwater robots that can take photos, capture samples and accurately measure to better manage underwater sea creatures system and appropriate exploitation because traditional fishing ground and fishery resources have bee over fishing. So much ocean explored by scientists begin to propel prediction of marine creatures numbers and direction of environment change, which finally keeps biological balance.

Among above issue, human beings actively develop other ocean resources to resolve ore resources and ocean energy resources as one of benefits deep sea exploration. But remember that obtaining in reverence is always true deed in history. If not, the ocean may probably take revenge on human beings.What more profound meaning to human being is hidden mysteries of ocean. Benefits deep sea exploration comes in a way like Titanic shipwrecks to be found by deep sea explorers. Through this way of exploration, human beings also have chance to learn more about history. Deep ocean exploration helps to human beings know more power of ocean and themselves. With modern popular portable underwater robot kit like Nemo, ordinary people enraptured with ocean are accessible to deep sea, start underwater photography and even explore mystery in deep sea.
