GeoTalk: What can you learn from a human hair?
Jim Ehleringer is Director of the Stable Isotope Ratio Facility at the University of Utah in Salt Lake City in the US. In the past few years he has been developing a method for deducing people’s diets and travel history from a sample of their hair. Here, he talks to the EGU press office about his research. Thanks for agreeing to chat, Jim. Can you tell me a bit about how your project started? This ...[Read More]

It’s not my fault
A line on a map is important. In the Beverly Hills region of Los Angeles a series of mapped fault lines are now the cause of a major controversy. Communities have been alarmed, money has been lost and legal proceedings are ongoing. It started in 1992. James Dolan and Kerry Sieh, two earthquake geologists at the California Institute of Technology, published a map in a field trip guidebook about the ...[Read More]

#EGU2014: Cleaning with Coffee
We’re drinking an enormous amount of coffee in Vienna this week, but the residues at the bottom of the cafetière usually end up in the bin. Kalliopo Fotopoulou, from the University of Patras in Greece, has found a way to transform that residue into something far more useful. Baking coffee residues in an oven changes them into a carbon rich “biochar”, which can be added to soils t ...[Read More]

Meltwater ponds halt new sea ice growth
Each September, battered by the relentless sun-filled days of summer, the smooth expanse of the Arctic Ocean reaches the climax of its annual transformation. Replacing the endless blanket of winter ice, a vast jigsaw puzzle stretches across the pole, a mosaic of soggy snow islands floating amid turquoise ponds of meltwater and inlets of dark blue sea. These meltwater ponds have been shown to drama ...[Read More]

EGU 2014: Air pollution in the Anthropocene
One of the key strands of the EGU so far this year has been discussion of the proposed new geological time period known as the Anthropocene. This concept was first proposed by the ecologist Eugene Stoemer in the 1980’s, with Nobel Prize Winner and atmospheric chemist Paul Crutzen bringing renewed attention to the term in the early 21st Century. It refers to the concept that the impact of hum ...[Read More]

EGU DIARIES: Day Two (Tuesday 29th April)
Tuesday was a seriously busy day! Again, I was in the situation where I found it difficult to choose which sessions to attend. I was spoilt for choice. There were a few highlights: an early morning session on geoethics and geoeducation proved to be an interesting experience whilst the session on geodynamics of the continental crust proved really relevant for my own research. I also attended my fir ...[Read More]

#EGU2014: Bright Sparks in Dirty Thunderclouds
Lightning bolts formed in dirty thunderclouds could help geologists to detect explosive volcanic eruptions. Volcanic lightning is very poorly understood, but Corrado Cimarelli, from the University of München, has been able to reproduce the phenomena in his laboratory. Volcanic lightning is broadly similar to lightning in thunderclouds, but the addition of ash makes the process more complex. Volcan ...[Read More]
