Cities are expanding faster than ever, often onto steep and unstable terrain. As urban areas grow, landslides increasingly threaten homes, roads, and critical infrastructure. To manage this risk, scientists produce landslide susceptibility maps, which estimate where landslides are most likely to occur. These maps are widely used by planners and decision-makers. But there is a quiet assumption buil ...[Read More]

A synergy of observations: Filling the gaps in an ocean colour chlorophyll-a record
Chlorophyll-a (chl-a), as the dominant photosynthetic pigment within phytoplankton, provides an indication of the phytoplankton biomass and are essential for understanding global and regional changes in primary production in the oceans. Multiple ocean colour satellites have unlocked routine synoptical scale observations of chl-a which now extends from 1997 to the present day. Differing numbers of ...[Read More]

HydroTalks: Prof. Sally E. Thompson on ecohydrology, vegetation, climate change and working across continents
In episode 7 of the Hydrotalks podcast, our guest was Dr. Sally Thompson (Sally Thompson – the UWA Profiles and Research Repository). She is a Professor at the University of Western Australia, and the Co-Director of the Centre for Water and Spatial Science. Her research spans ecohydrology, surface hydrology, and Critical Zone Science, exploring how vegetation and ecosystems interact with wat ...[Read More]

Finding Geothermal Energy with Structural Geologists!
Imagine harnessing the Earth’s natural warmth to heat our homes and generate clean electricity. That is the promise of geothermal energy. It taps into the heat from beneath the Earth’s surface, providing a consistent and low-carbon power source. Geothermal energy plays a crucial role in reducing carbon emissions because it produces very little greenhouse gas over its entire lifecycle. Studie ...[Read More]

Running Models, Chasing Bugs – from Crashes to Convection
Mantle convection may unfold the hidden stories of planetary interiors over billions of years, but geodynamic models can crash in milliseconds. While figures in papers often show smooth convective flows with elegant plumes and slabs, the path to those results is not very easy. This week, Prachi Kar, a PhD candidate at Arizona State University, shares her honest thoughts on the part of geodynamics ...[Read More]

GeoTalk: Meet Marie Cavitte, policy officer for the Cryosphere Division, member of the EGU Climate Hazards Task Force, former Blue Book trainee
Welcome, Marie! Could you please introduce yourself to our readers? Hi, my name is Marie Cavitte. I’m a glaciologist and climatologist with a passion for the polar regions. I spent 10 years studying Antarctica. I started off during my Masters, then PhD, looking at the oldest ice on Earth, hunting for THE region of the ice sheet that might contain million-year-old ice. An ice core has been drilled ...[Read More]

From Signals to the Sea: Building an AI Sound Library for the Ocean
We chatted with Bram Cuyx, an underwater acoustics AI research engineer at the Flanders Marine Institute (VLIZ) in Belgium, about his unique path from engineering into marine science. In this interview, he shares how he made the leap from signal processing in electronics to listening to the soundscape of the North Sea, what it’s like to build a sound library for AI, and why acoustics might b ...[Read More]

McMurdo Sound’s 70th anniversary: An expedition journal by Julia Martin
It was October 28, 2022 around 3 p.m. Fascinated by the majestic white snow-covered mountain caps, deep-blue sea ice cracks and light-blue pressure ridges, I gently press my nose against the cold double-glassed window of the Royal New Zealand 757. The tires smoothly touch the ground, and the warm voice of the flight attendant fills the dry air in the aircraft: “Ladies and Gentlemen, welcome to Ant ...[Read More]

Peak glacier extinction in the mid-twenty-first century
Have you ever wondered how many glaciers will still exist in the future? Or how many glaciers we might lose each year in the coming decades? In our new study (Van Tricht et al., 2025), we shift the focus of glacier modelling from ice volume to individual glaciers. Because every glacier, no matter how small, can matter. Not necessarily for global sea-level rise, but for landscapes, ecosystems, cult ...[Read More]
