The Gower Peninsula in South Wales, United Kingdom, is a spectacular site to view a sunset. However, to geologists, the shore is also a prime spot to find artifacts from Earth’s ancient and recent past. “The limestone coastline is dotted with caves that are rich in Quaternary flora and fauna,” said Mike Smith a visiting researcher at Plymouth University (UK) and photographer of this featured image ...[Read More]

Though now submerged under 53 m of ocean waters, there once was a land bridge which connected North America with Asia, allowing the passage of species, including early humans, between the two continents. A new study, published in the EGU’s open access journal Climate of the Past, explores when the land bridge was last inundated, cutting off the link between the two landmasses. The Bering Strait, a ...[Read More]

GeoTalk: Talking about ‘ocean burps’ with James Rae

Laura Roberts-Artal September 25, 2015

Meet James Rae, a research fellow at the Earth & Environmental Sciences Department at the Universty of St. Andrews and this year’s recipient of the Biogeosciences Division Outstanding Young Scientists Award.

Trying to understand the reasons behind the global warming of our climate is a never ending quest for scientists across the geosciences. Scientists often rely on deciphering past change to help us understand, and perhaps predict, what might happen in the future. Many will be familiar with the common saying ‘the past is the key to the future’. This is exactly what James Rae, a research fellow at th ...[Read More]

During ice ages landscapes are sculpted by the power of advancing glaciers. From rock scratches, to changing mountains and the formation of corries, cirques and aretes, through to the formation of valleys and fjords, the effects of past glaciations are evident across the northern hemisphere landscape. Perhaps not so familiar, drumlin fields are also vestiges of the erosive power of ancient ice she ...[Read More]
