Project information
Project aim
Methane is a significant greenhouse gas, second in importance after carbon dioxide. Methane also plays an important role in establishing the ozone layer, which helps protect the Earth from ultraviolet radiation. Atmospheric methane concentrations prior to 1978 are known from analysing ice core air. Our aim is to determine the isotopic signature of methane from Pre-Industrial times in order to determine its origin.
