How is it that Earth developed an atmosphere that made the development of life possible? A study published in the journal Nature Geoscience links the origins of Earth’s nitrogen-rich atmosphere to the same tectonic forces that drive mountain-building and volcanism on our planet. It goes some way to explaining why, compared to our nearest neighbours, …[Read More]

Follow the ongoing L’Aquila appeal
The seismological community is anxious with the ongoing court proceedings against fellow Italian seismologist with regards to the 6th April 2009 L’Aquila earthquake. The news of seismologists guilty of manslaughter was major news for the entire world (e.g., BBC) and condemnation came in fast (e.g., The Guardian, EOS, AGU). Internal discussions between scientists are still very active during major international conferences (e.g., EGU 2014) with …[Read More]
EGU2015: Applying for financial support to attend the General Assembly
The EGU is committed to promoting the participation of both young scientists and established researchers from low and middle income countries who wish to present their work at the EGU General Assembly.

Soil wind erosion is influenced by soil inherent properties
Carlos M. Asensio Grima casensio@ual.es Department of Agronomy University of Almería, Spain Soil wind erosion is influenced by soil inherent properties, different wind characteristics and surface vegetation cover. For a better understanding of this process is necessary to explain the effect and consequences of wind erosion on the ground and especially in agricultural areas of …[Read More]
Imaggeo on Mondays: Polygon ponds at sunset.
Thinking of the Arctic conjures up images of vast expanses of white icy landscapes punctuated by towering icebergs and a few dark rocky masses; certainly not a green landscape with a series of water pools amongst rolling hills. The image below is perhaps more reminiscent of the temperate Scottish or Welsh countryside; but don’t be …[Read More]
Images of soil erosion
Frans Kwaad, physical geographer Soil erosion is the removal of soil from cultivated land at a rate that is (much) higher than the rate that would occur under the natural vegetation at the considered site. Besides the loss of fertile topsoil, soil erosion entails the dissection of cultivated land by rills and gullies and the …[Read More]

After a busy summer, we have returned to the blogosphere…
Well, it has been a while since either of us has produced a GeologyJenga post, so first of all apologies on this front. We both have the same excuse – finishing our PhD theses! Our mutual deadline was 30 September 2014, and thankfully we both made it. The last few months were challenging at times …[Read More]
How I start good supervisory relationships with graduate students
Many professors are confused about why a certain graduate student is happy or unhappy, under performing or performing well. I am far from a perfect supervisor, but I try to avoid this confusion by getting to know my graduate students on a relatively deep but professional level as quickly as possible, by doing the following …[Read More]
Open Access: Access to knowledge
“Access to knowledge is a basic human right.” Yet sadly as scientists we are often forced to operate in a framework in which this is not always the case. This week sees the celebration of the eighth Open Access Week, and whilst there have undoubtedly been many achievements by the Open Access (OA) movement since …[Read More]
