Satellite images are not just wonderful for science, they also capture public interest during periods of intense and news grabbing weather. Earlier this month North America was gripped by a prolonged Arctic Chill, plunging the continent into freezing temperatures and smashing temperature records in the process. Consecutive satellite images tracked the southward progress of the …[Read More]

Earthquake lights
A very interesting article about earthquake lights has been published in this month Seismological Research Letters. Earthquake lights are an aerial phenomenon when unusual light is seen just above the ground or high up in the sky before and/or during an earthquak. Mysterious lights in the sky have been a sensation ever since but their appearance has …[Read More]
GeoTalk: Matt Herod on awesome outreach and education
Matt Herod has long been part of the EGU Blog Network, where he writes about all things geochemistry from his base in the University of Ottawa. In this week’s GeoTalk, we had the chance to talk to Matt about all the other science communication activities he’s been up to – from mentoring kids in Canada …[Read More]
Diamonds aren’t Forever
Boom & Bust in the Namib Desert Namibia is mostly desert. Like its neighbour South Africa, the country was gifted with diamond-bearing Kimberlites. The Sperrgebiet (or “forbidden territory”), where the diamonds are concentrated, is strictly off-limits to the public. Namibia’s natural resources have played an important role in shaping the development of this inhospitable …[Read More]

From synchrotron to super-volcano – buoyed up by magma
Devastating supervolcanoes can erupt simply due to changes that happen in their giant magma chambers as they slowly cool, according to a new study. This finding marks the first time researchers have been able to explain the mechanism behind the eruptions of the largest volcanoes on Earth. Geologists have identified the roots of a number …[Read More]
Has climate change changed in the media?
Whether in a concerned, neutral, alarmist or sceptical tone, climate change is often reported in the media. But has the press approached this subject differently over the years? Marion Ferrat takes a look at the UK press coverage of the last two IPCC reports and investigates how the treatment of climate change has changed in …[Read More]
Were dinosaurs the masters of social integration?
Back in the Late Cretaceous, the USA was divided. Not politically, but by a vast continental sea called the Western Interior Seaway, splitting the continent into two separate landmasses. The western one of these, known as Laramidia, played host to some of the popular dinosaurs like Parasaurolophus, or ‘Elvis’ in Pete Postlethwaite dialect, and the …[Read More]
Guest Post: Hilary Dugan – Ice as a platform for understanding lake ecosystems
Today we have a new guest post written by current PhD candidate and Antarctic researcher on her very fascinating field work. Actually, she wrote this post while at McMurdo station. Hilary and I have known each other since our time at Queens University in Kingston, when she was one of my TA’s and was doing …[Read More]
Imaggeo on Mondays: Long live the lichen!
Lichens are amazing organisms. They are a composite of algae and fungi, each of which supports the other through the exchange of nutrients (fungi to algae) and carbon (algae to fungi). They are also capable of making a home out of seemingly inhospitable rock surfaces – and what’s more – making the most of these surfaces …[Read More]
