2 About the Japan Agency for Marine-Earth Science and Technology The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) was established in 1971 as a core institution for marine science and technology research and development in Japan. I went. So far, in order to investigate the vast and harsh ocean and deep sea, we started with saturated diving technology for people to dive into the sea, underwater acoustic technology to examine the seabed with sound waves, manned submersible research vehicle, unmanned exploration. We have been developing technology for excavating the seabed ahead of the issuance of the special stamp "50th Anniversary of the Japan Agency for Marine-Earth Science and Technology". Furthermore, by making full use of these cutting-edge technologies, we are producing advanced results in various research fields such as oceanography, earth science, biology, and microbiology in order to solve the mystery of the earth system.

3 Design of postage stamps to be issued I drew the state of the sea together with the research vessels and explorers owned by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC).

(1) Marine research vessel "NATSUSHIMA" / Deep-sea submersible research vessel support mother ship "YOKOSUKA " "NATSUSHIMA" was built in 1981 as a support mother ship for the manned submersible research vessel "Shinkai 2000" and started operation. Since the retirement of "Shinkai 2000" in 2004, he has contributed greatly to the construction of the Nankai Trough earthquake and tsunami observation and monitoring system DONET as an oceanographic research vessel. Since the operation of "YOKOSUKA " started in 1990, it is still active as the mother ship of the manned submersible research vehicle "Shinkai 6500". In 2013, we conducted a round-the-world voyage "QUELLE 2013" and succeeded in investigating the deep-sea extreme environment of the Southern Hemisphere, which had been limited to scientific research by manned submersible research vehicles, together with "Shinkai 6500".

(2) Deep-earth exploration vessel "CHIKYU" This is the world's highest level scientific drillship completed in July 2005. In April 2012, we conducted the "Tohoku-Pacific Ocean Earthquake Survey and Excavation" off the Oshika Peninsula in Miyagi Prefecture, and succeeded in collecting geological samples including faults that caused huge earthquakes and tsunamis and measuring temperatures. Furthermore, after that, the mechanism of this huge earthquake and tsunami was clarified by analyzing and researching the collected samples. In addition, in 2012 "Shimokita Hachinohe offshore biosphere excavation" and 2016 "Muroto offshore marginal biosphere excavation survey: T-limit", we conducted research on the habitat limit of life, and under the seabed in the deepest part of the world. We have achieved results such as discovering microbial communities. She is still active as the flagship ship of the international program of earth and life sciences.

(3) Manned submersible research vehicle "Shinkai 2000" The "Shinkai 2000" is a manned submersible research vehicle that can dive to a depth of 2,000 m. Completed in 1981 as Japan's first full-scale deep-sea manned submersible research vessel, it dives into various waters around Japan and discovers colonies of Calyptogena soybeans that perform chemical synthesis off the coast of Sagami Bay and Hatsushima. It has greatly contributed to the progress of deep-sea research in Japan, such as the discovery of hydrothermal vents in the Okinawa Trough. On November 11, 2002, the operation was suspended after successfully completing 1,411 dives, and it is now statically preserved at the Enoshima Aquarium and is on permanent display.

(4) Autonomous unmanned spacecraft "Jinbei" ・ Autonomous unmanned spacecraft "Yumeka" "Jinbei" and "Yumeka" are autonomous unmanned exploration developed to investigate the deep sea environment for scientific purposes. It is a machine. We approach the seabed in a stable posture and conduct more precise topographical surveys. It cannot carry humans, but it can automatically investigate pre-programmed target routes.
(5) Manned submersible research vehicle

"Shinkai 6500"

(5) Manned submersible research vehicle "Shinkai 6500" The "Shinkai 6500" is a submersible research vehicle that can carry researchers and dive to a depth of 6,500 m. Completed in 1989, it has made more than 1,500 dives so far, while making improvements such as improving maneuvering and maneuvering performance by adding a propulsion device and increasing the number of observers by unifying the pilot who was a two-person system. I did. A deep-sea survey, such as discovering the world's second whale fall community in the Torishima Seamount around the Izu-Ogasawara Trench, and diving to a depth of 5,350 m in the Japan Trench to discover a large crack that is thought to be the effect of a huge earthquake. It is very active in.
