New detector sniffs out origins of methane

Instrument identifies methane's origins in mines, deep-sea vents, and cows

09-Mar-2015

Methane is a potent greenhouse gas, second only to carbon dioxide in its capacity to trap heat in Earth's atmosphere for a long time. The gas can originate from lakes and swamps, natural-gas pipelines, deep-sea vents, and livestock. Understanding the sources of methane, and how the gas is formed, ...
