Abstract

The first clue to the existence of the deep-Sea hydrothermal vent ecosystem became evident when a large white shell was observed on a DEEP TOW camera at a depth of 2,600 m in the eastern Pacific Ocean, Galapagos Extension Area, on May 29, 1976. The following year, 1977, the hydrothermal vent became known to the world after the manned submersible Alvin (deep-sea research vessel DSRV) was used to explore the seafloor near the Galapagos Islands. Since then, hydrothermal vents have become increasingly important in the study of fundamental phenomena such as the Earth’s material-energy cycle and the origin of life on this planet. To date, marine science studies in this field have mainly been conducted by developed countries and more than 550 areas of hydrothermal activity have been found worldwide.The study of hydrothermal vents in the Indian Ocean was conducted by Japan, Germany, and France in the late 1990s, relatively late compared to that in other oceans. However, the importance of hydrothermal systems in the Indian Ocean has increased and attracted the attention of many researchers. Indeed, exploration of the Indian Ocean hydrothermal vents has been actively conducted by the United States, China, and India since the mid-2000s.Discovery of the hydrothermal vent system is rated as one of the most remarkable scientific events of the 20th century. The hydrothermal vent system is considered to be highly suitable as a976.
