When volcanoes erupt, they can release into the atmosphere a number of different gases initially stored in their magma, such as carbon dioxide, hydrogen sulfide, and sulfur dioxide. These kinds of gases can have a big influence on Earth’s atmosphere, even at distances hundreds to thousands of kilometres away. A team of researchers have found evidence that sulfur emissions from volcanic eruptions i ...[Read More]
Imaggeo on Mondays: Recreating monster waves in art and science
Featured in this blog post is a collection of images that gives a picture-perfect example of life imitating art. The photos in the left column are three consecutive still frames of a breaking wave that scientists generated in a lab environment at the University of Edinburgh in the UK. The pictures in the centre and right columns show the same wave images, but now superimposed with the famous 19th ...[Read More]
GeoPolicy: Preventing mercury leakage from a WWII submarine
I recently had the opportunity to interview Matthias Kaiser, a professor at Bergen University and, at the time of the interview, Director of the Centre for the Study of the Sciences and the Humanities. He is part of an expert team that has given scientific advice to Norwegian policymakers, highlighting the issues that should be considered when dealing with the U-864 submarine wreckage and its carg ...[Read More]
Imaggeo on Mondays: Robotics at the service of the polar science
This picture was taken in the Arctic in May 2018. It shows the unmanned marine vehicle Proteus in front of the tidewater glacier Conwaybreen in the Kongsfjorden in Spitsbergen in the Svalbard Archipelago. The front of tidewater glaciers is an almost vertical wall of ice standing over the sea where direct measurements are very critical due to the possibility of sudden fall of enormous blocks of ice ...[Read More]
