The air we breathe is full of tiny particles that can have a big impact on our climate. Industrial activities have greatly increased the number of these particles, cooling the climate and potentially offsetting some of the warming due to greenhouse gases. In this post Kirsty Pringle introduces new research that suggests that it might not be possible to quantify the effect of industrial emissions o ...[Read More]

Imaggeo on Mondays: Stirring up a sandstorm

March 18, 2013

These are the outwash plains for the Icelandic volcano, Katla: An outwash plain (or sandur) is a broad, shallowly sloping region ahead of a glacial front. They are made up of material that has been deposited by glacial meltwater, released either by geothermal heating or a subglacial eruption. The extensive volcanism and abundance of ice-capped volcanoes in southern Iceland means that the outwash p ...[Read More]

A story of Spitfires? Archaeological geophysics in Burma (Part 1)

December 19, 2012

Buried beneath the soils of Burma lies a mystery that has been almost 70 years in the making: were a shipment of Spitfire aircraft concealed beneath a British airbase at the end of the Second World War? Dr Adam Booth, a geophysicist at Imperial College London and regular GeoLog contributor, is part of an archaeological team who are trying to unearth the truth in this tale. He’ll be posting to GeoL ...[Read More]
