This Sunday, July 26, marks the International Day for the Conservation of the Mangrove Ecosystem. We are currently experiecing critical crossroads globally, where groundbreaking data on global forest recovery collides with the immediate threats of an escalating climate crisis.El Niño is pushing Pacific sea surface temperatures toward levels that rank among the highest on record, …[Read More]
Welcome to GeoTalk, Trevelayne! Could you introduce yourself to our readers? I hold a Bachelor’s degree in Psychology and a Master’s degree in Cognitive Neuroscience. Throughout my career, I’ve developed and implemented communication strategies that translate scientific knowledge into clear and engaging narratives. Currently, I’m the Project Communications Officer for the MOSMIN (Multiscale Observation Services …[Read More]
Floods are shaped by complex and nonlinear interactions between weather patterns, rainfall, soil properties, topography, land cover, and how wet a catchment already is. This complexity is one reason machine learning (ML) is increasingly used in hydrology. ML models can learn patterns from large and complex datasets with many variables. Early in my PhD, while …[Read More]
Working with marine carbonate-system observations has taught me how much effort lies behind every row of an oceanographic dataset: long hours at sea, careful sampling, laboratory analyses, calibration and quality control. A single bottle of seawater may represent only one place, one depth and one moment, but when many such samples are brought together, they …[Read More]
Every time something burns incompletely —whether in a car engine, a factory furnace, a cooking fire, an agricultural field set alight after harvest, or a vast wildfire sweeping through savanna grasslands— tiny particles of black carbon are released into the atmosphere. You might know these more simply as soot. These particles are so small that …[Read More]
Beneath the serene landscapes we inhabit, the Earth’s crust is a battleground of constant, immense, and invisible tectonic forces. While humanity typically only notices this deep-seated stress when it violently releases in the form of an earthquake and volcanoes, these forces have always been shaping the structural bedrock of our planet. Understanding this hidden architecture …[Read More]
Introduction When people hear the word „volcano“, they usually think of a magmatic volcano with impressive pyroclastic eruptions or lava flows. However, mud volcanoes are different. Mud volcanoes erupt what we call mud breccias, a mixture of gas, water, and fine sediments. The eruptions generally occur due to deep generation of hydrocarbons and gravitational instability …[Read More]
Iceland is pure geology. When I travelled there in 2015, it felt like stepping into another world: surreal, raw, and unforgettable. Geology wasn’t just something to observe or study: in Iceland, it’s something you inhabit. The landscape doesn’t just sit there, it feels alive. It hums, it shifts, it speaks. And whether you’re a geologist …[Read More]
If you have ever tried to draw a geological cross-section under a fantasy map, Homer is surprisingly cooperative (and if you remember my Middle-earth geology post, you already know I live for this). The Odyssey is full of real places and real people—Troy, Mycenae, Sparta—stitched together with storms, monsters and divine interventions that would make …[Read More]
