Volcan Agua, Guatemala Taken from the side of the Acatenango, another volcano, this image shows the stratovolcano Agua towering over the landscape. Agua was the location of a catastrophic debris flow/lahar in the mid 16th Century, destroying the then capital city of Guatemala.

How do the chemical ghosts of dinosaurs help their preservation?
For some years now, Mary Schweitzer and her team have been researching the idea that organic molecules can be preserved for millions of years, specifically within dinosaurs. They have used a plethora of chemical and biotechnological techniques to demonstrate that, within animals like Tyrannosaurus rex, it is possible to find the residue of structures such as blood vessels and even proteins. Natura ...[Read More]

Fires in South East Asia
Smoke from a number of agricultural fires is currently blanketing Thailand and Cambodia. This is shown below in the satellite image from the MODIS instrument on the TERRA satellite. The red dots are classed as ‘thermal anomalies’ by the satellite instrument and are usually indicative of fires burning in these locations. The majority of the fires are occurring in grass and cropland area ...[Read More]

Small volcanic eruptions and the global warming ‘pause’
A new paper in Nature Geoscience by Santer and colleagues revisits the volcanic scenarios used in modern climate model simulations. The authors consider the effects of including a ‘more realistic’ model for the influence of small volcanic eruptions on the climate system over the past two decades. Of course, more realistic means more difficult.. and one of the long-standing and unresolv ...[Read More]

Where did all the mammoths go?
Let’s go meta. Recently, ecologist extraordinaire Dr. Jacquelyn Gill (or is it Professor cos of that weird American system?) wrote a wonderful review article on the extinctions that affected many large mammal species during the last 50-10,000 years. This period is known as the Quaternary, and was a time when ice ages were running rife between warmer periods, and herds of enigmatic mammals ro ...[Read More]

Towards better quantifying human impacts: Looking back on the PAGES Workshop in Leuven
Firstly, I’d like to express my sincere thanks to Dr Jennifer Clear (Czech University of Life Sciences, Prague) for her input to this blog article. The first week of February saw dozens of scientists arrive at the Katholieke Universiteit Leuven for the PAGES Focus 4 Workshop. This event brought together geomorphologists, soil scientists, palaeoecologists, archaeologists and palaeolimnologist ...[Read More]

Imaggeo on Mondays: Friends in the field
Out in the field you encounter all sorts of wildlife and while mosquitos are the most frequent (and most unwelcome), they generally don’t interfere with your equipment or your data. The same can’t be said for all animals though, and many scientists have to strap their equipment out of reach, barricade it with barbed fences or place it in a relatively indestructible black box. It’s a particular pro ...[Read More]

Guest Blog: The Influence of Himalayan Geology
Amber Madden-Nadeau is studying Geology at Imperial College London. Amber recently wrote a report on the geology of the Himalayas, with a focus on the Ladakh region, as part of our hazards education project. Here, Amber summarises the important aspects of Himalayan geology and the influence they have on people’s lives. The Himalaya mountain range stretches over 2500km, influencing th ...[Read More]
