This week’s Imaggeo on Mondays is brought to you by Gert Verstraeten, who takes us through the formation of some of the striking landscapes in the Mediterranean – the badlands. For more than 7 years I have been performing research on reconstructing historic erosion rates in the Taurus Mountains in Southwest Turkey. Badlands are heavily eroded landscapes, where soft, clay-rich rocks and soils have ...[Read More]

Placement Report – Sam Marshall (CAFOD, April 2013)
At the end of each GfGD placement we ask the student completing that placement to think about his/her experiences and write a short report (available to download here). In April 2013, Sam Marshall spent a week working with disaster risk reduction advisor Dr Kate Crowley (pictured with Sam Marshall) at the international NGO CAFOD. Today we share Sam’s report – outlining what he got up t ...[Read More]

Friday Photo (84): Wildlife in the Field – Ostriches at the Craton Boundary
These wild ostriches (two female on the left hand side, one male on the right) are lined up alongside the boundary between the Congo and the Kalahari cratons in southern Namibia. The craton boundary is marked by a visible fault scarp. (c) Geology for Global Development 2013

Muon musings – how penetrating particles could let us peer beneath Mars’ surface
Muons are penetrating particles generated by cosmic rays. Muon radiography – or muography – is the large-scale equivalent of using x-rays to generate images. Except, instead of using x-rays to take a closer look at your broken arm, we can use showers of muons to take a look inside large geological structures – we’re talking several kilometres in size here! When cosmic rays meet the atmospher ...[Read More]

In the News (June 2013)
We highlight some of the items that have caught our eye in the news recently Volcanic History In a recent study, published in IOP Science, Irish historical records were used to trace the impact of volcanic eruptions on climate over a 1200 year period. Geological events are recorded by geochemical proxies and physical changes within the rocks – these are the lines of evidence that geol ...[Read More]

Imaggeo on Mondays: Aerosols over Hurricane Irene
This image – rather than our usual Imaggeo photo – is a simulation representation of Hurricane Irene, as it moved up the coast of the United States. The red-yellow areas in the image represent regions with high aerosol concentration that have been swept upwards in convective clouds and the blue areas are clean regions. The aerosols enter Irene along rain bands, before being wrapped into the centre ...[Read More]

Guest Blog: Disaster Resilience in Dharamsala, India
John McCarthy and Sam Bradley are collaborating to develop an earthquake awareness and disaster resilience program for vulnerable communities in Dharamsala, India. The region is predicted to have an extremely large earthquake in the next 50 years and they are looking to raise awareness, develop community programs and improve the resilience capacity for the population. John and Sam both have Master ...[Read More]

Friday Photo (83): Wildlife in the Field – Giant Millipede Inspects Stromatolites
A giant millipede kindly provides a scale for a photo of some stromatolites in the Nama group, Namibia. Microbial communities grow upwards towards the light. Each growth phases is cemented by carbonate grains that stick to the sticky EPS substance that the communities produce, forming layered stromatolite columns. The stromatolites pictured above formed 550 million years ago – just as some o ...[Read More]
