The invisible shield from the centre of the Earth

The invisible shield from the centre of the Earth

The Earth’s magnetic field plays a prominent role in our everyday life. From birds and bees to many modern-day technologies rely on the magnetic field, and yet, our understanding on its long- and short-term behavior is far from complete. In this week’s post, Annique van der Boon shows how geology and paleomagnetic studies can help us in understanding the long-term activity of EarthR ...[Read More]

The Sassy Scientist – The Spinning Top

The Sassy Scientist – The Spinning Top

Whether from posed questions, other blog posts and cinematic detours, the core of Earth is every now and then sparking some interest. In a similar way “Inception” or “Shutter Island” spark interest: it sounds cool, you want to get what is going on, but although you tried several times, you still don’t get it. Today I will report on the answer to a question originally ...[Read More]

Magnetic field generation and its reversal in dynamo models

Magnetic field generation and its reversal in dynamo models

Generation and reversal of the Earth’s magnetic field have remained one of the most controversial topics. In this week’s geodynamics 101, Debarshi Majumder, a PhD student from the Indian Institute of Science, gives a brief overview of the theory of geodynamo reversal and discusses some of the preliminary results obtained from numerical modelling. A planetary magnetic reversal is one of ...[Read More]
