During mid-December 2013 to mid-February 2014 the UK was hit by six major storms bringing record precipitation, strong winds, huge waves and generating overall hazardous conditions. Despit ...[Read More]

Image of the Week – Mushrooms at zero degrees = hair ice?!
When you go down to the woods today you’re in for a big surprise….. hair ice! Did you know that there is a type of ice called hair ice? It is shaped like fine, silky hairs and looks like white candy floss. It grows on the rotten branches of broad-leaf trees during humid winter nights when the air temperature drops slightly below 0°C. A 100-year-old theory states that hair ice a ...[Read More]

Boost the PICO sessions @ EGU GA
EGU’s Pico’s (Presenting Interactive COntent®) are awesome and a lot of fun!! But at this year’s EGU General Assembly there was no Seismology PICO lead session. How sad was this? Why would this be? Can we do anything to change this? But wait, how much do you actually know on presenting or preparing a PICO…? Right, just what we thought… Perhaps not that much. There are many benefi ...[Read More]

Coffee break biogeosciences–Urban bees found to feed on flowers
Honey bees, a highly important pollinator, have suffered a number of declines and population collapses in recent years. The growth of urban centers has contributed to a loss of foraging habitat and an introduction of new food sources. A recent study conducted across the rural-urban boundary of Raleigh, North Carolina, USA examined the feeding sources of urban and rural honey bees using δ13C measur ...[Read More]

Imaggeo on Mondays: Storm on the Rock
This is a photograph of Uluru, in the Northern Territory of Australia, on a hot and humid summer afternoon. As lightning flashed about, torrential rains swept across the landscape and silver rivulets of water began to rush down the sides of the mountain. Uluru is made of red-coloured Proterozoic arkosic sandstones, a coarse grained lithology rich in quartz and feldspars. However, on rare days such ...[Read More]

Great walls of fire – Vitrification and thermal engineering in the British Iron Age
It’s long been recognised the peoples of European prehistory occasionally, and quite deliberately, melted the rocks from which their hilltop enclosures were made. But why did they do it? In today’s blog post Fabian Wadsworth and Rebecca Hearne explore this question. Burning questions Throughout the European Bronze and Iron Ages (spanning 2600 years from 3200 BC to 600 BC), people constructed stone ...[Read More]

Short video on Geomorphology – Sediment Dynamics in high-mountain Environments
Geomorphology is the science of processes shaping the earth surface. Especially in high-mountain environments, where the relief is steep, these processes move a great amount of material. This 10 minute video features Geomorphologists from different parts of the world, explaining what happens when glaciers retreat and expose sediments to erosion and how it affects us humans. Furthermore it attempts ...[Read More]
