Why Strike and Dip Conversions Confuse Even Professional Geologists ?

Nkodia Hardy January 16, 2026

Geologists taking structural measurements in the Congo River, with the overlay title: Why Strike and Dip Conversions Confuse Even Professional Geologists?

Whether you are a student, educator, or industry professional, you have likely encountered the myriad conventions used for recording geological orientations. For students, this landscape can be perplexing; for professionals, it may lead to the sinking feeling that a crucial undergraduate lecture was missed. Indeed, converting strike and dip measurements between different systems, such as Quadrants ...[Read More]

Is How We View the Atmosphere Too Dry?

Óscar Pérez-Priego and Andrew S. Kowalski January 15, 2026

Many people think about air as a fixed mix of gases like nitrogen, oxygen, and carbon dioxide (CO2). But the main reason the composition of air changes—water vapour—tends to get overlooked. Scientists often remove it from atmospheric samples before analysing air composition, and this convenient habit can make us forget something surprising: water vapour isn’t just “in” the air; it is air, and when ...[Read More]

Prevent before repair: What a new hydrology-based index reveals about river ecological status

Michael Kyei Agyekum January 15, 2026

When I first began analysing agricultural pressures in German river networks, I expected the familiar story of nutrient loads, pesticide traces and differences between landscapes. What I did not expect was how narrow the ecological safe operating space has become for many rivers. Even small increases in agricultural pressure, especially from pesticides, reduced the likelihood of achieving good eco ...[Read More]

Mathematical closed-form solutions in Geodynamics: insightful or detrimental?

Dimitrios Papadomarkakis and edited by Constanza Rodriguez Piceda January 14, 2026

Mathematics is certainly not every scientist’s cup of tea. Despite the latter, they are, for the most part, very important, since most problems, regardless of their complexity, start and end with a mathematical equation (or set of equations). In this week’s blog, Dimitrios Papadomarkakis (student at the National Technical University of Athens), discusses the subject of closed-form (analytical) sol ...[Read More]

Last minute information for EGU26 abstract submission

Bettina Schaefli January 12, 2026

If you have not yet submitted your abstract for this year’s General Assembly (GA2026), do not forget to submit as early as possible this week (instructions here), this avoids any last minute technical challenges. . You can submit only one abstract (except for invited speakers or if you submit to an EOS-session). For your hydrology-related research, the call-for-abstracts programme proposes t ...[Read More]

When small-scale turbulence imprints on the global atmospheric circulation: Uncovering the Cause of the Double Intertropical Convergence Zone Bias in ICON

Clarissa Kroll, Robert Jnglin Wills, Ulrike Niemeier, Luis Kornblueh and Andrea Schneidereit January 12, 2026

One feature stands out in any map of tropical rainfall from satellites: a narrow band of intense precipitation encircling the globe near the equator. This is the Intertropical Convergence Zone, a key feature of the global atmospheric circulation that imports moisture into the tropics and exports energy to higher latitudes. But for decades, climate models have struggled to simulate this feature cor ...[Read More]

How Lava Domes Grow: Field Observations and Thermo-Mechanical Insights from the 1979 Soufrière Eruption

Takafumi Maruishi January 8, 2026

To kick off the New Year, we have invited a guest author, Takafumi Maruishi, a researcher in the Research Division for Volcanic Disasters / Center for Volcano Research Promotion, National Research Institute for Earth Science and Disaster Resilience, Japan. He explains the scaling law of lava dome growth and its physical insight. Effusive eruptions—when magma reaches the surface and is extruded as ...[Read More]

Building the Earth in a sandbox

Conor Farrell and edited by Michaël Pons January 7, 2026

Building the Earth in a sandbox The Main Ethiopian Rift stretches for hundreds of kilometers through Ethiopia, a massive fracture where Africa is slowly tearing apart to birth a new ocean. However, the processes driving this continental breakup remain hidden deep beneath layers of volcanic rock and millions of years of geological history. Today, in a laboratory in the heart of the be ...[Read More]
