The Jiaolong (pronounced Jye-ow-long) is China's first manned deep-sea submersible. Its name means "Flood Dragon," a powerful creature from Chinese myths, and it is a perfect name for a machine that explores the deep ocean. Developed between 2002 and 2012, the Jiaolong was designed to carry one pilot and two scientists to the darkest parts of the sea.
The main goal of the Jiaolong project was to help China explore most of the world's ocean floor. In June 2012, the submersible made history during a dive in the Mariana Trench. It successfully reached a depth of 7,062 meters (about 23,170 feet). This record showed that the Jiaolong could reach over 99.8% of the global seabed, making China one of the leading nations in deep-sea technology.
The Jiaolong is not just a travel machine; it is a vital tool for science. Its crew uses it to perform complex tasks. These include collecting samples of deep-sea life, rocks, and mud from the ocean bottom. Scientists study these samples to learn more about ocean geology, chemistry, and how life survives in extreme pressure and cold. The submersible can also take high-definition photos and videos, and it has special arms to pick up items or plant markers on the seabed.
Since its record-breaking dive, the Jiaolong has continued its work in the Pacific, Indian, and Atlantic Oceans, completing hundreds of missions. It helps us understand deep-sea resources and the effects of climate change on these remote ecosystems. The Jiaolong represents a huge step in our human effort to explore and understand the mysterious world beneath the waves.
