DRI scientist co-authors study outlining vast differences in polar ocean microbial communitiesEurekAlert | 10 Oct 2012
An international team of scientists, led by Dr. Alison Murray, an Associate Research Professor at the Desert Research Institute's Division of Earth and Ecosystem Sciences reported this week in the Proceedings of the National Academy of Science that a clear difference exists between the marine microbial communities in the Southern and Arctic oceans, contributing to a better understanding of the biodiverisity of marine life at the poles and its biogeography.
Antarctic ice may hide huge methane menaceNew Zealand Herald | 30 Aug 2012
The melting of Antarctic ice could release huge amounts of greenhouse gas trapped under the continent's surface - creating a feedback loop that would accelerate climate change.
Antarctic may host methane storesBBC | 29 Aug 2012
Large volumes of methane - a potent greenhouse gas - could be locked beneath the ice-covered regions of Antarctica, according to a study.
