Imaggeo on Mondays: The perfect partnership
Pogonophores are deep sea worms that thrive in dark, deep sea conditions thanks to the presence of symbiotic bacteria. The bacteria are chemoautotrophic, that is, they fix carbon through oxidation processes, rather than using light to fix it, as is the case for photosynthesis. By utilising oxygen in the water, the bacteria can oxidise compounds such as hydrogen sulphide in order to fix carbon. The ...[Read More]

Vegetation research in Finnish Lapland: mountains, sunshine and reindeer
People started warning me about the mosquitoes back in April. It sounded grim. But when I arrived in Finnish Lapland in August, the mozzies had peaked earlier in the season when temperatures were unusually high, and were all dead. This was a fortunate escape: Miska Luoto of the University of Helsinki and his team of researchers, who I was following as part of an EGU Science Journalism Fellowship, ...[Read More]

There are two images below showing the scene from the TERRA satellite as it passed over the Eastern Atlantic off the coast of Morocco. The first image shows the plume of smoke from wildfires from Madeira that swept through the island last weekend. The second image sh ...[Read More]

Becoming a Ghost Buster: What triggers sapropel formation?
As I touched upon in our first post, we can use the magnetic properties of minerals in sediments (and other environmental materials) to understand changes in environmental and climatic conditions. This is known as environmental magnetism. The basic idea is to identify links between the magnetic properties of a material and environmental conditions and depositional processes. This approach is not a ...[Read More]

Guest Blog: Community Water and Sanitation at Cranfield University
Alison Parker explains how and why she ended up lecturing in International Water and Sanitation at Cranfield Water Science Institute. Over millions of years, geological forces have built the Himalayas and carved the Grand Canyon and put abundant natural resources at human beings’ disposal. However, it is obvious that in the short time that humans have been on the planet they have had an eno ...[Read More]
