Susanne Hemes (RWTH Aachen University, Germany) The image was taken using a ‘Zeiss – Supra55’ Scanning Electron Microscope at 15,000x magnification and 10kV electron acceleration voltage, as part of my PhD work on the porosity in fine- and coarse-grained Boom Clay samples. The picture shows pores in framboidal pyrite aggregates, embedded in a fine-grained clay matrix. Boom Clay i ...[Read More]

A view on peatlands
During the last FESP4 (4th Int Meeting on Fire Effects on Soil Properties, Vilnius, Lithuania), participants in the meeting visited the Dzūkija National Park. This park was established in 1991 in the region of Varena (southern Lithuania). The park extends over approximately 550 km2 along the Nemunas River, near the border between Lithuania and Belarus. The purpose for which it was founded was to p ...[Read More]

Guest Blog: Holes, Hazards and Honey
Tim Middleton, GfGD Advocacy Officer, interviews Dr. Andrew Longley, Director of the Nicaragua-based NGO Nuevas Esperanzas. It’s a warm June day, so I suggest that we sit outside. We take our coffees onto the rooftop terrace and admire the view across Oxford. Before long, however, Andrew is zipping up his fleece and starting to shiver; he’s used to the rather warmer climate in Nicaragua. In fact, ...[Read More]

Spinning a yarn about perovksite
Magnesium silicate perovskite is the most abundant silicate in our planet. Never given a mineral name in its own right, it is unstable at Earth’s surface and has only been observed directly in the lab, rather than the field. So it fails to meet the criteria set down by the masters of mineral names, the International Mineralogical Association. Instead it adopts that given to calcium titanate, ...[Read More]
Between a Rock and a Hard Place
How to finish a PhD in three years*
Welcome to our blog! Between a Rock blog is a multi-author effort, comprising five (and counting) PhD students from the School of Earth Sciences at the University of Bristol. We’re pretty excited to be welcomed into the EGU network and look forward to sharing our PhD journeys and science stories with you. To get a feel of what we write about, you can check our old material at betweenarock.co.uk. Y ...[Read More]

Welcome to G-Soil!
The G-Soil team would like to begin by welcoming you to G-Soil. G-Soil is the official blog of the Soil System Sciences Division of the EGU and is a means of communication for all those interested in soil science and related areas. We hope you enjoy the blog as much as we enjoy the soil under our feet. Soil is the interface between the crust and atmosphere, and is the basis of life on Earth. The ...[Read More]

Four degrees: Discussions on climate change, policy, environmental geochemistry and sustainability
As we enter the 400ppm world for the first time in a good chunk of geological history, issues of environment, sustainability and climate change are, more than ever, a source of discussion – and often heated dispute – in the media. As these issues are debated by governments and policy-makers, hardly one day goes by without a series of news articles on topics such as shale gas, warming c ...[Read More]

How to Find Ghosts in Sediment Cores
Hi! And welcome to Geology Jenga and our very first blog post :)! As this is our first post, we have picked a topic that integrates elements of both our research interests. In this initial post, we aim to give a flavour of the science that will be covered on our blog in the future, provide an introduction to the techniques we employ in our PhD’s and hopefully provide some useful insight into how s ...[Read More]
