The submarine in the world

　In this topic, I write about the submarine in the world.

　Let's explore from the original purpose of a submarine first. Originally, with the submarine, it was used as a kind of a warship. The power was based on human power. As it was called from there the air engine, the electric motor, and a gasoline engine and an electric motor, it has progressed through long history. the background -- a color -- the negative history of war exists deeply. Use any the submarine has expanded the width of the people's activity greatly. 

　Here, "Deep-submergence vehicle" which is a submarine used for the purpose of "investigation of deep sea" is introduced.

NAUTILE of france 

　Right picture is deep-submergence vehicle of France,  "NAUTILE". (NAUTILE is a thing with the mind of a "nautilus") This was made in 1984. It can get in this ship to three persons. Full length is 8.0 meters and width is 2.7 meters. It is the features 120 hours and that very long time diving can be carried out. Even a depth of 6000 meters serves as a range which can be dived now. It visited by trench investigation also to Japan in 1985. It is for carrying out cooperative study. The plan is called a "KAIKO plan." Plate tectonics with the close relation with an earthquake was studied. It achieved big success. 

ALVIN of USA

　Left photographs are U.S. deep-submergence vehicle and "ALVIN". It was applied for the first time on June 5, 1964. This is also a ship of three-person riding. The pilot is the rule which one person and a scientist declare themselves two. I can stay 4500 meters of deep sea till 9 hours now. ALVIN is famous also for having conducted diving investigation of the Titanic number. 

　Please look at the image of the deep sea living thing of the Gulf of Alaska photoed by this ALVIN. 

　How was it? A deep sea living thing and environment have projected this animation clearly, and it is a very worthy animation. ALVIN has managed thing diving 4000 times or more. Expectation becomes increasingly large still more at this ship of active service.

SHINKAI6500 of Japan

　Then, let's see representation deep-submergence vehicle of Japan of our country. The name of this ship is called "SINKAI6500." It has been considered as submergence vehicle of three-person riding under which it can go in the world most deeply till recent years. It can dive to the depth of 6500 meters. As for this, full length has 9.6 meters and a 2.7-meter-wide body. Extraction of the living thing of deep sea, a sedimentary rock, and hot water is also possible. Bottom time is about 9 hours.


　This SHINKAI6500 has achieved many success until now. The remarkable result in recent years is investigation in the focus ocean space of the Great East Japan Earthquake. The big crack was checked to what and the seabed. This is discovery indispensable to future Japan's research. In addition, discovery of a hydrothermal venting hole, discovery of a new living thing, etc. are only the investigations which repaint history. What kind of investigation is advanced from now on? It cannot let cooperation of each country out of sight.
