One of the most rewarding parts of fieldwork on volcanoes is when the parts start to fit together, and hunches turn into firmer ideas. When piecing together ancient volcanic eruptions, the process often starts with the discovery of the trace of a new deposit in a road cut section. This might be something as simple as the appearance of a scruffy yellow or orange band that catches our eye as we pass ...[Read More]
A French and Algerian study team seeks markers of underwater earthquakes off the Algerian coast. The team also matched the site’s paleoseismic history to land-based historical reports. Wayne Deeker reports. The Mediterranean Sea represents the boundary between the African and Eurasian plates. Yet the fault segment off the Algerian coast is one of the most active in the western Mediterranean. It is ...[Read More]
Crikey, it’s been 3 months already?! *panics* At Imperial College, new PhD students have to produce an initial plan of study within the first three months of setting off, and submit it for independent assessment. Having uploaded mine just now (not in the slightest bit late..), I figured I’d share it here! It’s a broad outline of what I’m aiming to do for the next wad of mon ...[Read More]
Beware of the sealions (‘cuidado lobos marinos’) declares the sign at Valdivia fish market, which stretches along the docks in this southern Chilean city. And it’s no joke either, as a large clan of these creatures has set up stall in the estuary beneath the fish market, ready to feast on the daily pickings cast over the sea rail. We are not here, however, to admire the sealife; or to ...[Read More]
The British Geophysical Association is hosting a two day conference on the 14th and 15th of February, 2013. The focus of the conference will be the use of geophysics in future energy challenges. Novel geophysical techniques will be needed to maximise output from conventional reserves and safely explore unconventional reserves. Once the deep reserves are depleted, the empty pore spaces in the rock ...[Read More]
Buried beneath the soils of Burma lies a mystery that has been almost 70 years in the making: were a shipment of Spitfire aircraft concealed beneath a British airbase at the end of the Second World War? Dr Adam Booth, a geophysicist at Imperial College London and regular GeoLog contributor, is part of an archaeological team who are trying to unearth the truth in this tale. He’ll be posting to GeoL ...[Read More]
Among geoscientists, the beautiful island of Ireland is best known for its Giant’s Causeway, an area with some 40,000 polygonal columns of layered basalt that formed 60 million years ago as a result of a volcanic eruption. But another recognisable feature of the Emerald Isle, is its lush green vegetation, a product of the island’s mild climate and frequent rainfall. It was on a rare sunny day of a ...[Read More]
In this post I explore some of the issues that can arise when an economy is dominated by the oil or mining industry. I discuss some of the inherent problems with the nature of the extraction industry. In next week’s blog post, I will move on to talking about how we can manage the extraction industry responsibly. Although I manage the GfGD Blog, in this instance I am blogging in a personal ca ...[Read More]
We have a vacancy for a science communication or science journalism student in Europe to work at the press office of the 2013 General Assembly, which is taking place in Vienna, Austria, from 07-12 April. Applications from geosciences students with science communication experience are also welcomed. The student will join the team assisting the EGU press officer and the journalists at the press cent ...[Read More]
The speed and extent of Greenland’s ice sheet melt dominated the media over the summer, and for good reason. Dramatic satellite images showed that, in just a few days, 97% of the island’s ice sheet surface thawed, melting over a larger area than at any time in more than 30 years of satellite observations. Usually, during the summer only around half of the surface of Greenland’s ice sheet melts and ...[Read More]
