This week’s Imaggeo on Mondays is brought to you by the photographer himself, Fabien Darrouzet who captured the beautiful glacial landscape during a summer expedition to the Arctic. This picture was taken in Svalbard (78° lat.) in June 2012. I was there for one week in order to observe the transit of the planet Venus in front of the Sun. I came here because at this time of the year, the Sun is sh ...[Read More]
GeoTalk: Robin Andrews
This month in GeoTalk, we spoke to Robin Andrews, a PhD candidate at the University of Otago, New Zealand, who takes us through the explosive aspects of one of Geology’s most thrilling disciplines – volcanology. First, could you introduce yourself and let us know a little about your work and what drew you to volcanology? Ah, introductions! Well, I’m Robin Andrews, a British postgraduate volcanolog ...[Read More]
Imaggeo on Mondays: The Chalk Cliffs of Étretat
Étretat is a coastal region in northern France, well known for its stunning geological landscape. Particularly the headland you see here. Headland erosion is perhaps one of the best known processes in coastal erosion, where a crack in the headland is opened and enlarged by hydraulic abrasion. Continued wave action causes the widened crack or cave to break through the headland and form an arch. As ...[Read More]
Geosciences Column: Perfecting Palaeogeographic Reconstructions
We model the changes in the geographic location of continents via paleogeographic reconstructions. However, the current methodology for generating these reconstructions is not without problems! Publication of palaeogeographic reconstructions is scarce, probably resulting from the difficulties associated with generating them. Conventional reconstructions are presented as static maps which have poor ...[Read More]
