This week’s Imaggeo on Mondays is brought to you by Joanna Nield, a lecturer in physical geography at the University of Southampton. Nield explains how volcanic eruptions can impact glaciers and how ash fall can both accelerate and slow down glacial melt… This photo was taken at Fjallsjökull, Iceland in July 2011, shortly after the eruption of Grímsvötn volcano (21 – 30 May 2011). The Gríms ...[Read More]

Monday paper: Mean age of carbon in fine roots from temperate forests and grasslands with different management
E. Solly, I. Schöning, S. Boch, J. Müller, S.A. Socher, S.E. Trumbore, M. Schrumpf. 2013. Mean age of carbon in fine roots from temperate forests and grasslands with different management. Biogeosciences, 10, 4833-4843, doi:10.5194/bg-10-4833-2013 Abstract Fine roots are the most dynamic portion of a plant’s root system and a major source of soil organic matter. By altering plant species div ...[Read More]

AGU 2013 Days 4 & 5: measurements & models
My fourth and fifth days at the AGU Fall Meeting involved dashing between multiple sessions to take in a number of talks on (surprise, surprise) aerosols! The main strand running through them from my point of view was how there are major efforts to construct large datasets of aerosol properties that can be used to test our understanding via numerical models. Aerosols are complex and tend to stick ...[Read More]

Reading Past Sea Ice Coverage from strange red blobs!
Sea ice is an interesting phenomenon, especially to a Canadian. The question around this time of year that always arises in the news is will this be a big sea ice year, will we set a new record low, high (haha) or will it be just average? This is a question that gets a lot of study and media attention. People run countless statistical models to predict sea ice conditions and try to predict the pas ...[Read More]

…Ever thought about joining a research cruise?
Over the next month Jens Weiser, a masters student at the University of Bremen, will be reporting from a research cruise off southern Africa. This week he’s setting the scene and setting seaward with 14 other young scientists in a bid to understand more about the region’s biology and geology… When I started my Masters programme, Marine Geosciences, at the University of Bremen one and a half years ...[Read More]

AGU 2013 Day 3: secondary organic aerosol – animal or vegetable?
My third day at the AGU 2013 Fall Meeting involved lots of talks on one of the trickiest parts of aerosol science – secondary organic aerosol (SOA). We’ve known for several years now that SOA is ubiquitous across the globe and it is often the most dominant aerosol chemical species in many environments and this is particularly true in the industrialised regions of the Northern Hemispher ...[Read More]

Registration for the EGU 2014 General Assembly is open!
The EGU General Assembly brings together geoscientists from all over the world to one meeting that covers all disciplines of the Earth, planetary and space sciences. This year, the conference will have a theme: The Face of the Earth. Much like a human face, our planet exhibits a huge diversity of shapes and forms. This theme aims to celebrate that diversity in geoscience processes – from the core ...[Read More]

Cracked soils
Vertisols are dark clayey soils that show cracks at least during some part of the year. Normally, Vertisols are found in depressions or plain areas under subhumid or semiarid climate, with a wet and a dry season. Although climax vegetation is savanna, grassland or woodland, Vertisols are very fertile, so that agricultural use is very common. However, the process of swelling/shrinking makes Vertiso ...[Read More]
