Is geological mapping becoming obsolete?

Is Geological Mapping Becoming Obsolete?

Geology students typically experience some form of mapping education as part of their course and attitudes towards this baptism into the geosciences vary from adoration to utter hatred. Whatever the opinions of the students, however, it is widely recognised that performing mapping exercises is an excellent way to learn the basics of structural geology which underpins aspects of both further geolog ...[Read More]

Rainfall related geohazards: floods, landslides and mudslides in Rio – A dangerous combination of nature and human-related factors

Rainfall related geohazards: floods, landslides and mudslides in Rio – A dangerous combination of nature and human-related factors

Rainfall-related geohazards in Brazil’s poorer, mountainous city margins could be mitigated using better urban planning and communication. Our own Brazilian blogger Bárbara Zambelli Azevedo explores the problem and possible solutions. I come from Brazil, a country well-known for its beautiful landscapes, football and carnival. Ok, some stereotypes are true, indeed. Situated in the middle of the So ...[Read More]

Imaggeo on Mondays: Northern lights in northern Norway

Northern lights in Tromsø, displaying the collisions between electrically charged particles from the sun which penetrate the earth’s magnetic shield and strike atoms and molecules in our atmosphere. Collisions excite the atoms causing electrons to move to higher-energy orbits, further away from the nucleus. When electrons move back to lower-energy orbits, they release particles of light call ...[Read More]

Of Karst! – short episodes about karst

Post by Andreas Hartmann,  Assistant Professor in Hydrological Modeling and Water Resources at the University of Freiburg. Episode 4 – Karst Groundwater: quick and slow at the same time? We often associate groundwater with large water storage and very slow water movement for instance compared to rivers. But is it possible that groundwater flow can be as quick as stream flow and, at the same aquife ...[Read More]

Image of the Week – The solid Earth: softer than you might think!

  Global sea level is rising and will continue to do so over the next century, as has once again been shown in the recent IPCC special report on 1.5°C. But did you know that, in some places of our planet, local sea level is actually falling, and this due to rising of the continent itself?! Where is this happening? In places where huge ice sheets used to cover the land surface during the last ...[Read More]

How to make a subduction zone on Earth

How to make a subduction zone on Earth

Subduction zones are ubiquitous features on Earth, and an integral part of plate tectonics. They are known to have a very important role in modulating climate on Earth, and are believed to have played an essential part in making the Earth’s surface habitable, a role that extends to present-day. This week, Antoniette Greta Grima writes about the ongoing debate on how subduction zones form and persi ...[Read More]

Private solutions, public science: how to bridge the gap?

Private solutions, public science: how to bridge the gap?

The urgency around many sustainability issues leads some billionaire investors to throw caution in the wind, frustrated with the pace of academic research. Robert Emberson sympathises with private projects like the Ocean Cleanup, even when things go wrong. ‘How’, he asks, ‘might we build a constructive bridge between ambitious entrepreneurs and scientific sceptics? ‘ Reading and writing about sust ...[Read More]
