What is the Walker Circulation? The El Niño Southern Oscillation, or ‘ENSO’, is one of the major causes of year to year variability in Earth’s climate. ENSO is characterised by: changes in the temperature of the ocean’s surface in the tropical Pacific Ocean, and by changes in atmospheric circulation in an east-west direction above the Pacific Ocean. Number two in that list is what makes ENS ...[Read More]
What’s the connection between novel generative image models and seismic denoising? Daniele Trappolini from Sapienza Università di Roma has led an effort to utilise these exciting techniques for seismological applications. This blog post will give a beginner-friendly introduction to generative modelling and ‘diffusion’ models, before explaining how Daniele and his group have been ...[Read More]
2023 draws to a close. Looking back, our NH Division Blog has rolled out 20 different posts! We’ve chatted with awesome medallists, tackled current challenges in natural hazards, and showcased key projects and activities in the field. But who are the lovely and creative minds behind this? In this year’s final post, we’re going to find out together. The Blog Editorial Team is cu ...[Read More]
Once a year, GMPV enthusiastic scientists from all over the world gather around in Vienna for the fabulous EGU General Assembly, where very exciting and ground breaking science is presented to peers. While for some, the EGU may be reduced into a solid crazy week at the GA, for others is a year-round duty. The existence of the GMPV Division science officers ensures that every year GMPV’s earl ...[Read More]

Let’s continue the journey of discovering cool facts about sea ice which started with breaking the ice. This time, we’re diving into a fascinating part of the Arctic and Antarctic: the Marginal Ice Zone (MIZ). Imagine a place where the vast, frozen world of sea ice meets the moving waters of the ocean underneath. This is the MIZ, a unique area where air, water, and ice mix and mingle. ItR ...[Read More]
Geothermal resource development faces a major obstacle: the expensive exploration process. Unsuccessful drilled wells can discourage interest and disrupt economic plans. Understanding the relationship between geologic structures and geothermal fluid flow is critical to successful exploration. Various methods, such as geochemistry, geophysics, structural analysis and modeling, aim to create a relia ...[Read More]
Most earthquakes on Earth start in the shallow, brittle part of the planet. However, there are several regions where earthquakes happen deep in the mantle. Where are these regions? Why do these earthquakes get so deep? In this week’s blog post, Ayako Tsuchiyama from the Massachusetts Institute of Technology (MIT) takes us on a journey into the mysterious world of deep earthquakes. Growing u ...[Read More]
In January 2023, I visited the Amazon Forest in Suriname. During my visit, I met indigenous people known as the Saramaccers, a Maroon tribe residing in the heart of the Amazon Forest. I found it fascinating that the Saramaccers consider themselves an integral part of nature. Their motto is ‘If you respect nature, nature will be your friend and stand by you’. Nature extends a helping ha ...[Read More]
In 2020, ocean scientists discovered a new island off the Pine Island Glacier ice shelf, naming it after the Norse goddess, Sif. The island is one of many new regions being exposed in the wake of increased ice shelf melting and glacial retreat. While these newly-revealed lands have been discussed in the Arctic and alpine ecosystems, the uncovered island and coastlines of Antarctica have been less ...[Read More]
