Image of the Week – ROVing in the deep…

Robotics has revolutionised ocean observation, allowing for regular high resolution measurements even in remote locations or harsh conditions. But the ice-covered regions remain undersampled, especially the ice-ocean interface, as it is still too risky and complex to pilot instruments in this area. This is why it is exactly the area of interest of the paper from which our Image of the week is take ...[Read More]

How good were the old forecasts of sea level rise?

How good were the old forecasts of sea level rise?

The Geodynamics 101 series serves to showcase the diversity of research topics and methods in the geodynamics community in an understandable manner. We welcome all researchers – PhD students to Professors – to introduce their area of expertise in a lighthearted, entertaining manner and touch upon some of the outstanding questions and problems related to their fields. Our latest entry for the serie ...[Read More]

Minds over Methods: Making ultramylonites

Minds over Methods: Making ultramylonites

“Summer break is over, which means we will continue with our Minds over Methods blogs! For this edition we invited Andrew Cross to write about his experiments with a new rock deformation device – the Large Volume Torsion (LVT) apparatus. Andrew is currently working as a Postdoctoral Research Associate in the Department of Earth and Planetary Sciences, Washington University in St. Louis, USA. ...[Read More]

Image of the Week – Bioalbedo: algae darken the Greenland Ice Sheet

Image of the Week – Bioalbedo: algae darken the Greenland Ice Sheet

Most of the energy that drives glacier melting comes directly from sunlight, with the amount of melting critically dependent on the amount of solar energy absorbed compared to that reflected back into the atmosphere. The amount of solar energy that is reflected by a surface without being absorbed is called the albedo. A low albedo surface absorbs more of the energy that hits it compared to a high ...[Read More]

How can we use meteorological models to improve building energy simulations?

How can we use meteorological models to improve building energy simulations?

Climate change is calling for various and multiple approaches in the adaptation of cities and mitigation of the coming changes. Because buildings (residential and commercial) are responsible of about 40% of energy consumption, it is necessary to build more energy efficient ones, to decrease their contribution to greenhouse gas emissions. But what is the relation with the atmosphere. It is two fold ...[Read More]

The Venus enigma: new insights into ‘Earth 2’

The Venus enigma: new insights into ‘Earth 2’

Apart from Earth, there are a lot of Peculiar Planets out there! Every 8 weeks, we look at a planetary body worthy of our geodynamic attention. This week Richard Ghail, lecturer in Engineering Geology at Imperial College London in the United Kingdom, discusses Earth’s sister: Venus. Geologists have long held the view that they only have the results of one experiment: Earth. The growing list ...[Read More]

What speleothems can tell about the past climates !

Name of the proxy: Stable isotope ratios of carbonates in speleothems Type of proxy: Precipitation, atmospheric circulation, CO2 availability in soil, soil productivity Paleoenvironment: Continental environments Period of time investigated: Present day to 10 million years How does it work? Speleothems are inorganic carbonate deposits growing in caves that form from super-saturated cave waters (wit ...[Read More]

NetherMod Day 4 & 5 – Secret Summary

NetherMod Day 4 & 5 – Secret Summary

I hear you exclaiming: “Why merge day 4 and 5 together? What happened to the secret summary of day 4?” Well, I have to admit, apart from being your daily NetherMod reporter, I also needed to present my poster, so apologies for the delay and merge. Day 4 started with a keynote talk from Dave Stegman with a surprise topic (He had never handed in his abstract. Apparently this is a possibi ...[Read More]

Image of the week – Learning from our past!

Understanding the climate evolution of our planet is not an easy task, but it is essential to understand the past if we are to predict the future! Historic climate cycles provide us with a glimpse into a period of time when the Earth was warmer than it was today. Our image of the week looks at these warmer periods of time to see what they can tell us about the future! For example, during the Plioc ...[Read More]

NetherMod Day 5 – Putten an end to Nethermod: interviews with attendees

NetherMod Day 5 – Putten an end to Nethermod: interviews with attendees

Today is the fifth and final day of the XVth International Workshop on Modelling of Mantle and Lithosphere Dynamics, or “Nethermod”, here in Putten, The Netherlands. Despite the overcast conditions outside, the lively scientific program included keynotes by Paul Tackley and Carolina Lithgow-Bertelloni in the morning and Clint Conrad and Louise Kellogg in the afternoon. With over 120 at ...[Read More]
