Scientists discover new 'cold vent' on ocean floor

Chinese scientists discovered an active "cold vent" in the South China Sea during a research voyage that concluded on Thursday.

Cold vents are areas where methane, hydrogen sulfide and other hydrocarbons seep out off the ocean floor, providing a unique environment for organisms or the development of topographic features.

Samples and data of organisms, water, gas and sediments were collected to further the study of the evolution and mechanisms of cold vents, according to the China Geological Survey of the Ministry of Natural Resources.
