Imaggeo on Mondays: Antarctic winds make honeycomb ice

These delicate ice structures may look like frozen honeycombs from another world, but the crystalline patterns can be found 80 degrees south, in Antarctica, where they are shaped by the white continent’s windy conditions. In Western Antarctica is a 9-kilometre line of rocky ridges, called Patriot Hills. Often cold wind furiously descends from the hills across Horseshoe Valley glacier, sculpting do ...[Read More]

Lombok and Fiji – or why a M6.9 earthquake can be worse news than a M8.2 event

Two magnitude 6.9 earthquakes in Indonesia in the space of two weeks, 20 km apart. Meanwhile, a magnitude 8.2 event in the Pacific. Did you get any questions about the end of the world being upon us, how come all these quakes happen so close together and why the Fiji event was so harmless?       Latitude Longitude Origin time depth Magnitude Region 8.2597° S 116.4363° E 2018-08-05 1 ...[Read More]

An overnight train view of China’s Anthropocene – Part 2

An overnight train view of China’s Anthropocene – Part 2

Science fiction is no match for industrial non-stop China. Electric bikes zip across the cities of Shanghai and Beijing, and soundtrack the neon nights with their passing whirr. Here, some kind of two-wheeled revolution has taken place which are we completely unaware of in the West. It’s Blade Runner meets Total Recall in a future which has already come to pass. The very existence of our ele ...[Read More]

What can the Cretaceous tell us about our climate?

What can the Cretaceous tell us about our climate?

The Cretaceous The Cretaceous period features a particularly interesting climatic episode in the Earth’s geological history. It follows the Jurassic Period, better known as the time the dinosaurs inhabited Earth and spanned the period between 145.5 and 65.5 million years ago. The Cretaceous is the last period of the Mesozoic Era, which ends with a well-known mass extinction event. At the end of th ...[Read More]

Imaggeo on Mondays: Fairy chimneys in Love Valley

Every year tourists from around the world flock to Love Valley in Göreme National Park in the Cappadocia region of central Turkey to marvel at the region’s peculiarly pointy geological features. These cone-shaped formations, known as ‘fairy chimneys’ or hoodoos, dominate the park’s skyline, with some rocky spires extending up to 40 metres towards the sky. While the name ‘fairy chimney’ suggests my ...[Read More]

GeoTalk: To understand how ice sheets flow, look at the bedrock below

GeoTalk: To understand how ice sheets flow, look at the bedrock below

Geotalk is a regular feature highlighting early career researchers and their work. In this interview we speak to Mathieu Morlighem, an associate professor of Earth System Science at the University of California, Irvine who uses models to better understand ongoing changes in the Cryosphere. At the General Assembly he was the recipient of a 2018 Arne Richter Award for Outstanding Early Career Scient ...[Read More]

SunPy: a Python solar data analysis environment

SunPy: a Python solar data analysis environment

Introduction For many years now we know that our star the Sun influences the Earth in many different ways, via the total solar irradiance, solar energetic particles and coronal mass ejections. Understanding the influence of the Sun on the Earth requires many different types of measurements. For example, NASA’s Solar Dynamics Observatory (SDO) spacecraft, produces over 1 terabyte of data per day (P ...[Read More]

Slimy Landscapes

When we think about how our landscapes evolve and change we probably tend to go straight for the big stuff, things like the climate, tectonics or geology, and in my previous blog I looked at how rainfall contributes to changing the planet’s surface. However, it is not just the big stuff which controls these changes, smaller things do as well, for example changes in land cover (ie, from grasses to ...[Read More]

An overnight train view of China’s Anthropocene – Part 1

The nighttrain from Shanghai to Beijing is a comfortable affair. The train is new and clean. My travel partner and I can charge our phones and relax on soft beds. The railway is almost frictionless, and overall the experience is similar to any ride in the West. But outside, as the vehicle roars through the early night, things become increasingly hazy. As we reach further out from the Shanghai metr ...[Read More]
