QINGDAO: Chinese scientists identified bubbles from some hydrothermal vents in the western Pacific Ocean as supercritical carbon dioxide, and this is the first time that natural supercritical carbon dioxide has been discovered on Earth.
A team from the Institute of Oceanology of the Chinese Academy of Sciences (CAS) and the Center for Ocean Mega-Science of CAS discovered the natural supercritical carbon dioxide at the depth of 1,400m in seawater during an investigation conducted in 2016 through a homegrown deep-sea in situ Raman detection instrument.
