Earlier this year we ran the second I’m a Geoscientist event, an online chat-based game show in which school kids vote for their favourite geoscience communicators. In this week’s GeoTalk, Laura Roberts talks to Andi Rudersdorf, a neotectonics PhD student and winner of this year’s I’m a Geoscientist… First, for those who didn’t been following I’m a Geoscientist, can you tell us a little about you ...[Read More]
Layer upon layer of sand, clay and silt, cemented together over time to form the sedimentary units of the Badlands National Park in South Dakota, USA. The sediments, delivered by rivers and streams that criss-crossed the landscape, accumulated over a period of millions of years, ranging from the late Cretaceous Period (67 to 75 million years ago) throughout to the Oligocene Epoch (26 to 34 million ...[Read More]
I have recently been confronted with the choice of buying a “new” car and this has proved to be a very tedious task with all the diversity of car that exists on the market today. However, one of my primary concerns was, of course, to find the least polluting car based on my usage (roughly 15000km/year). Cars (or I should say motor vehicles) pollution is one of the major sources of air pollution (p ...[Read More]
Like in a beautiful painting, layers of colour adorn the flanks of this volcano. In this week’s Imaggeo on Monday’s post, Stephanie Flude describes how these colourful layers came to be and gives an insight into why she became a geologist. What inspired you? Share your reasons for becoming a geoscientist with us in the comment section or via twitter using the hashtag #WhyGeo! “Why do you want to s ...[Read More]
Below the warm and tranquil waters of the Caribbean, some 480 km away from Puerto Rico, the North America Plate is being subducted under the Caribbean Plate. This has led to the formation of the Lesser Antilles volcanic arc; the result of the formation of reservoirs of magma as fluids from the down going North America Plate are mixed with the rocks of the overlying Caribbean Plate. The continued m ...[Read More]
What a place to work: Spectacular views from the top of the rugged and icy peaks of Tien Shan mountain range. The desire to better understanding global climate change took Leo Sold to this remote area of Central Asia. The frozen slopes of ice and snow in today’s Imaggeo on Mondays photograph hold some of the keys to understanding how the glaciers in this remote region are being affected by a warmi ...[Read More]
Aerosol particles typically have short life spans in the atmosphere (days to weeks) but they can travel far and wide in that time. They can be lifted up to new horizons, higher and higher in the atmosphere. This is important for their impact on our climate, for example, at least 20% of the uncertainty in the climate impact of black carbon aerosol is due to differences in its vertical distribution. ...[Read More]
From the rifting of the African continent, to mighty waterfalls in Slovenia, through to a bird’s eye view of the Glarus Thurst in the Alps, images from Imaggeo, the EGU’s open access geosciences image repository, they have given us some stunning views of the geoscience of Planet Earth and beyond. In this post we have curated some of our favourites, including header images from across our social me ...[Read More]
When the public think about natural hazards, space weather is not the first thing to come to mind. Yet, though uncommon, extreme space weather events can have an economic impact similar to that of large floods or earthquakes. Although there have been efforts across various sectors of society to communicate this topic, many people are still quite confused about it, having only a limited understandi ...[Read More]
Aerosol particles come in lots of different flavours and one of their most important properties is how they deal with incoming sunlight. Some are rather unwelcoming and send sunlight back to whence it came (space), which leads to a cooling of the atmosphere as the sunlight doesn’t reach the surface of the Earth. Others offer sunlight a warm(ing) embrace and absorb it, which heats up the atmo ...[Read More]
