Colour deficient vision and the geosciences; just another way of looking at things

Colour deficient vision and the geosciences; just another way of looking at things

Like a reasonably large proportion of the population, I have colour vision deficiency (also known as colour deficient vision or colourblindness). I’m not going to get into the technical aspects of what this is like as they are covered well here and here, and you can do an Ishihara test, and other tests here, to check your own vision. The other reason I’m not going to discuss the technicalities of ...[Read More]

Image of the Week – What darkens snow and ice?

“Be thou as chaste as ice, as pure as snow”. Hamlet, Act 3 Scene 1 (W. Shakespeare) Snow and ice are not always as pristine as one may think. If you have ever walked on a glacier or on a snowfield during summer, you might have already noticed that. In fact, both snow and ice are often darkened by impurities. In this blog post, you will learn about the main processes leading to ice and snow darkeni ...[Read More]

The Sassy Scientist – The Story of Plate Tectonics

As a new coping mechanism with reality, Sascha has been digging into some science history and asked: How did scientists discover plate tectonics? Dear Sascha, I do enjoy a good walk on the memory lane of scientific discoveries. You might know by now that great insight is gained when we look at data with fresh eyes. Hence, lots of advances in certain narrow scientific fields come from outsiders. In ...[Read More]

Atmospheric research in the middle of the Amazon forest: The Amazon Tall Tower Observatory celebrates its anniversary

It looks like a spike, orange against the blue sky, sticking out the green ocean of the Amazon forest: Standing 325 m tall, the Amazon Tall Tower Observatory (ATTO) is the highest construction in South America. This tower celebrates its 5th anniversary this year, while the ATTO research site, located ~150 km northeast of Manaus, Brazil, has been in operation for 10 years. During the past 5 years, ...[Read More]

Advanced geodynamic models of giant earthquakes

Though giant earthquakes are disastrous, they provide essential information to investigate earthquake physics. In this week’s news and views, Thyagarajulu Gollapalli, a PhD student jointly from the Monash University and the Indian Institute of Technology, Bombay, discusses our present understanding of such big earthquakes and how advanced numerical models will help to get a more precise picture of ...[Read More]

Natural Hazards 101 – What is a – natural – hazard?

We often talk about different natural hazards, how researchers investigate them and solutions to mitigate their effects on society, infrastructures and the environment. However, we have never really stopped for a moment to define a hazard, a natural hazard and much of the terminology in the field that can sometimes be evasive and not so straightforward to understand. Thus, we start this series of ...[Read More]

Is climate change making the weather more extreme?

Denver, Sept. 06: it is midday and Jonathan and Maria are sunbathing at City Park. They feel uncomfortable as the temperature has already reached 36°C. While they decide to go back home, their favoured weather app displays an unbelievable snowstorm watch for Tuesday Sept. 08. The forecast turns out to be rather accurate as all Colorado experiences one of the earliest snowstorms on record in Septem ...[Read More]

GeoTalk: Nadine Gabriel, creator of #AreYouSiO2? and Assistant Curator of Fossil Mammals.

Hi Nadine, thanks for speaking with us today, can you tell us a little bit about your background and how you got to where you are now? Thank you for inviting me! I’m a geologist and the Assistant Curator of Fossil Mammals at the Natural History Museum, London. I studied MSci Geology at University College London and I absolutely enjoyed the subject. It was really interesting to learn about the geol ...[Read More]

Climatic drivers of permafrost mounds in North American peatlands

Permafrost, or perennially frozen, peatlands are among the world’s largest terrestrial carbon stores and are particularly threatened by warming climates. Understanding how modern climate controls the distribution of permafrost peatlands is crucial for making confident predictions of their past and future extents. What are permafrost peatlands? Peatlands are wetlands that develop where cold, wet co ...[Read More]

The Sassy Scientist – Picturing The Perfect Petting Zoo

Kamal is happy, trotting around academia with a laptop in one hand, a cup of coffee in the other, and a faint grin on his face as he contemplates how to tackle the next big questions in geodynamics. Amazed that others do not consider academia as a radiant beacon on the horizon of potential career pathways, he is curious: If you were not a scientist, what would you be? Dear Kamal, I suppose I would ...[Read More]
