This month’s GeoPolicy post is an interview with the newly-appointed co-chair of the Intergovernmental Panel on Climate Change (IPCC) Working Group 1 (WG1): Valérie Masson-Delmotte. Valérie is also a Principle Investigator at the Laboratoire des Sciences du Climat et de l’Environnement, Paris. In this interview she discusses how she balances her two roles, what the IPCC has planned over the ...[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]
Imaggeo on Mondays: Moving images – Photo Contest 2016
Since 2010, the European Geosciences Union (EGU) has been holding an annual photo competition and exhibit in association with its General Assembly and with Imaggeo – the EGU’s open access image repository. In addition to the still photographs, imaggeo also accepts moving images – short videos – which are also a part of the annual photo contest. However, 20 or more images have to be submitted ...[Read More]
Livers, guts and gills: understanding how organisms become fossils
It’s 10am and Thomas Clements, a 3rd year palaeobiology PhD Student, is getting ready to check on his latest experiment. Full kited up in what can only be described as a space suit, Thomas carefully approaches the fume cupboard home to his latest specimen: a decaying seabass, balanced on a specially designed ‘hammock’ in a tank of salty water. Opening the lid to check on the rotting fish, Thomas i ...[Read More]

Imaggeo on Mondays: Half dome at sunset
Yosemite’s Half Dome stands, majestic, over a granite dominated terrain in the Yosemite Valley area; one of the most beautiful landscapes in northern America, and arguably, the world – it is also an Earth scientist’ playground. Stamped into the west slope of the Sierra Nevada range, the Yosemite Valley is a collection of lush forests, deep valleys, meandering rivers and streams, all punctua ...[Read More]
Geo Talk: One of the youngest EGU 2016 General Assembly delegates sends sensor to space
Presenting at an international conference is daunting, even for the most seasoned of scientists; not so for Thomas Maier (a second year university student) who took his research (co-authored by Lukas Kamm, a high-school student) to the EGU 2016 General Assembly! Not only was their work on developing a moisture sensor impressive, so was Thomas’ enthusiasm and confidence when presenting his r ...[Read More]
The final days of the mountain glaciers
In 1896 British lawyer, mountaineer and author Douglas Freshfield climbed an obscure mountain in the Caucasus called Kasbek and in his book detailing his adventures he described the mountain: “From this point the view of Kasbek is superb: its whole north-eastern face is a sheet of snow and ice, broken by the steepness of the slope into magnificent towers, and seamed by enormous blue chasms.” D Fre ...[Read More]
Imaggeo on Mondays: Earth Wave
Take a stroll along the norther beaches of the French Channel Coast, some kilometers east from the entrance of the Channel Tunnel, and you’ll encounter an imposing cliff of soft, sandy composition which dominates the landscape. On close inspection, the sediments which make up the Quaternary aged deposits of the Sangatte Cliff, are beautiful, revealing intricate patterns which hold the key to the g ...[Read More]
