The Antarctic Ice Sheet could be an overlooked but important source of methane, a potent greenhouse gas, according to research published today in Nature and conducted by an international team led by Professor Jemma Wadham from the University of Bristol's School of Geographical Sciences.For further information, see the University's main news page.

When ice sheets form, they overrun organic matter such as that found in lakes, tundra and ocean sediments, which is then cycled to methane under the anoxic conditions beneath the ice sheet.
