Imaggeo on Mondays: Curl up under a peat blanket

Rannoch Moor is the largest area of unbroken (no houses, no roads) blanket bog in the United Kingdom. Blanket bogs – as their name suggests – blanket the ground in an extensive layer of peat. They form in regions where there is high rainfall and comparatively little evapotranspiration. These waterlogged conditions are found throughout much of the northern hemisphere, and allow blanket bogs to form ...[Read More]

Melting, microbes and methane: Are we about to face a carbon apocalypse?

Marion Ferrat takes a look under the frozen layers of Arctic permafrost and discusses how these soils may come back to haunt us. The vast plains of Siberian or Canadian permafrost are a sight to behold. Hundreds, sometimes thousands of miles of frozen soils cover these lands, a cold and barren environment. In places, however, this permafrost is slowly melting away as a result of rising temperature ...[Read More]

What is soil structure?

Soil structure is the result of the spatial arrangement of the solid soil particles and their associated pore space. Aggregation mainly depends on the soil composition and texture, but is also strongly influenced by other factors such as biological activity, climate, geomorphic processes or the action of fire. Structure is a typical morphological soil property, which allows differentiating soil of ...[Read More]

Geosciences Column: Dating a bivalve

Just as the rings on a tree can be used to determine its age, the bands on a bivalve’s shell can tell us the how long it’s been around for. Warm, food-filled waters lead to greater growth in the summer and low plankton abundance (the principle food source for filter-feeding molluscs) leads to limited growth during the winter months – hence the banding. But pinning down the age of a bivalve m ...[Read More]

Sweeping soot out of the atmosphere

Efforts to slow the rate of global temperature rise in the 21st Century have for some time focussed on non-CO2 species or so-called ‘short-lived forcers’. As far as aerosols are concerned, black carbon (often referred to as soot) has been the main avenue to explore due to its capacity to warm the atmosphere by absorbing sunlight. Black carbon contrasts with most other aerosol species w ...[Read More]
