GeoTalk, featuring short interviews with geoscientists about their research, continues this month with a Q&A with Dr Aikaterini Radioti (University of Liège) who tells us about her work on auroras in Jupiter and Saturn. If you’d like to suggest a scientist for an interview, please contact Bárbara Ferreira. First, could you introduce yourself and let us know a bit about your current resea ...[Read More]

Geosciences Column: Predicting glacial lake outburst floods
In this month’s Geosciences Column, Amanda Gläser-Bligh writes about SAR (synthetic aperture radar) satellites and how they can be used to map glacier lakes and mitigate related flood hazards. Glaciers are a natural storage system and provide a perennial source of fresh water to the surrounding low-lying areas, which can be used for drinking water, irrigation, or even hydroelectricity. But when gl ...[Read More]
