The photograph shows the interaction of the first snow and an active lava flow during the 2014 / 2015 Holuhraun eruption in Iceland. The first snow fell onto a ground covered by fine black ash on 26 September 2014. While the meter thick lava flow advanced a few meters per day, it neither melted the snow nor flowed on top of it. Instead, it pushed a layer of centimetre-thick snow and millimetre-thi ...[Read More]

The thick packs of ice that pepper high peak of the world’s mountains and stretch far across the poles make an unusual time capsule. As it forms, air bubbles are trapped in the ice, allowing scientists to peer into the composition of the Earth’s atmosphere long ago. Today’s Geosciences Column is brought to you by PhD researcher Ruth Amey, who writes about recently published resea ...[Read More]
