Ice caps, valley glaciers, cirque glaciers, piedmont glaciers, ice sheets… I’m guessing that if you are a glaciology enthusiast, you have already heard about these types of glaciers. But you probably don’t know anything about regenerated glaciers, am I right? Well, you are in the right place! Let’s find out more about this little-known glacier type. Classifying glaciers Glaciers are classified on ...[Read More]
The August 2020 NPG Paper of the Month award goes to Josh Jacobson and colleagues for their paper “Beyond univariate calibration: verifying spatial structure in ensembles of forecast fields” (https://doi.org/10.5194/npg-27-411-2020). The ability to know the future has long been sought after and coveted. Yet, in contrast to prophecies and crystal balls, modern methods of prediction are ...[Read More]
Jade feels uncomfortable as she glides across the multi-faceted piazza of Earth sciences. Sometimes parents should think a tad longer about prospective names for their progeny, especially in case they push them into the world of minerals, rocks and equations-of-state. With all the facts on jade in her back-pocket, Jade wonders whether she should brush up and expand her knowledge: What is your favo ...[Read More]
After a few years spent at an Earth Science department researching social inequalities and hydrological extremes — i.e. floods and droughts — I have often been asked these rhetorical questions: “Isn’t it obvious that the weakest individuals or social groups suffer the most in case of extreme hydrological events? So, why should we study these inequalities?” Driven by these questions, and the years ...[Read More]
Geodynamics does not stop at the core-mantle boundary – the Earth’s outer core is a truly dynamic geosystem. This week Stefano Maffei (Research fellow) and Chris Davies (Associate Professor) from the School of Earth and Environment at the University of Leeds tell us more about the possible interplay between mantle and core and some of the remaining mysteries of the Earth’s magnetic field generatio ...[Read More]
Loess is an aeolian (wind-driven) silty sediment covering over 10% of the Earth’s land surface; it occurs predominantly in the mid-latitudes. On a global scale, loess is among the most widespread unconsolidated sediments, and of crucial importance for agricultural regions where loess deposits are known to form fertile soils because of its ability to store water and retain nutrients. Loess is compr ...[Read More]
The paper describes how large, rigid, aseismic regions can be defined with Euler’s theorem, which describes the geometry of motion on a sphere, i.e. the Earth’s surface. Points on these large and rigid blocks move in relation to other blocks describing small circles set by their rotation pole. The paper describes this as “paving stone theory”, where tectonic plates are “paving stones”, and success ...[Read More]
The June 2020 NPG Paper of the Month award goes to Sebastian Lerch and colleagues for their paper “Simulation-based comparison of multivariate ensemble post-processing methods” (https://doi.org/10.5194/npg-27-349-2020). Sebastian Lerch is a researcher at the Faculty of Mathematics of the Karlsruhe Institute Technology (KIT). He has a background in mathematics and statistics, his resear ...[Read More]
We often talk about forests for their importance in climate as a carbon sink and oxygen source. For their great role in the preservation of biodiversity, both for vegetation and as habitat for many animal species, for their potential in recreational activities. However, we do not talk a lot about forests in relation to natural hazards. Indeed, forests can be severely affected by natural hazards. T ...[Read More]
