Trying to understand the reasons behind the global warming of our climate is a never ending quest for scientists across the geosciences. Scientists often rely on deciphering past change to help us understand, and perhaps predict, what might happen in the future. Many will be familiar with the common saying ‘the past is the key to the future’. This is exactly what James Rae, a research fellow at th ...[Read More]
Deglaciation and formation of an ice rise with the ice-sheet model BISICLES. The simulation starts with an ice sheet in steady state that overrides a topographic high in the bed, close to the calving front. The sea level is then forced to rise steadily with 1 cm per year during 15 thousand years, and the simulation goes on until the ice sheet reaches steady state. The animation below shows that t ...[Read More]

The picture shows the Elbe Rivervalley, one of the major rivers of Central Europe. It was taken from the Bastei Bridge close to Rathen, which towers 194 meters above the Elbe River in the state of Saxony in the south-eastern Germany. This region belongs to the national park known as Saxon Switzerland. Together with the Bohemian Switzerland in the Czech Republic, the Saxon Switzerland National Park ...[Read More]
Creating 1 Hz-seismograms in a 3-D Earth model, and comparing them to observed body waves, is a dream that’s today still too expensive for routine use. But even tackling the problem for a spherically symmetric Earth poses certain challenges. Recently, a new tool entered the stage (you might have followed the Solid Earth discussion): Instaseis allows users to extract seismograms for a spherically s ...[Read More]
Open kickoff meeting of the PAGES working group held in Bonn, Germany, 19th – 21st Aug. 2015 The open kickoff meeting of the PAGES working group GloSS aimed to set the boundary conditions that will enable the GloSS-WG to meet its scientific goals within the next three years. Therefore, this workshop focused on the development of a list of proxies/indices of human impacts on soils and sediments tha ...[Read More]
As a volcanologist based in the UK, I am in the privileged position of rarely being affected by the natural events that I study. And, although I have worked for extended periods of time in earthquake-prone regions, I have never experienced anything more than the gentle nudge of a small tremor. Thirty years ago, shortly after 7 am local time on 19 September 1985, Mexico City was struck by a large e ...[Read More]
When you think of soil, what is the first thing that comes to mind? The answer will depend on your perception of soil: to some it has a patriotic meaning (“soil of Britain”, for example), while to others it has a strong agricultural connection and to an Earth scientist, well, it’ll depend on their field of expertise. A geotechnical engineer’s perception of soil is different to how it might be view ...[Read More]
Dear Colleagues, The annual Irish Geomorphology Group (IGGy) Workshop will be hosted at the Geological Survey of Ireland (GSI) in Dublin on the 25th and 26th November 2015 under the theme of ‘Extreme Events’ (a geomorphological perspective). The IGGy workshop will be followed by a themed IQUA (Irish Quaternary Association) meeting on November 27th, also at the GSI and also on ‘E ...[Read More]
The review paper The use of electromagnetic induction techniques in soils studies, by James A. Doolittle and Eric Brevik, has been awarded as the Geoderma’s Best Review of 2014. The Geoderma Best Paper Awards are chosen every year since 2013. Candidates are nominated by the Geoderma Editorial Board and a short-list is then created for voting by the editorial Board. The winner of the Geoderma ...[Read More]
