Imaggeo on Mondays: Stars in the Sand

This week’s Imaggeo on Mondays is brought to you by the photographer herself, Jana Eichel, who tells us about her expedition to the Mingsha Mountains and the stunning aeolian landforms that characterise the landscape. This photo was taken during a journey through Asia in spring 2012, which took me across Bangladesh, India and Nepal through to Western China and into the Gobi Desert. This journey al ...[Read More]

Geosciences Column: Larvae, Climate and Calcification

The absorption of atmospheric CO2 by the oceans results in a decline in ocean pH, hence ‘ocean acidification’, and reduces the availability of carbonate. This presents a problem to calcifying organisms (those that deposit calcium as either calcite or aragonite as hard parts) because they cannot produce their shells, valves (in the case of bivalves), or tests (in the case of diatoms) as readily. To ...[Read More]

Imaggeo on Mondays: Spying on the Arctic

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]
