Journey of the Indian plate

Journey of the Indian plate

Plume craton interaction is a fascinating geological phenomenon. The Indian plate, which has experienced several plume eruptions underneath it, is one of the best locations to study the effect of plume craton interaction. In this week’s news and view, I will provide an overview of the controversy and hypotheses related to the plume craton interaction …[Read More]

The Sassy Scientist – The Coffee Nirvana

Air travel is a thing of the past, or at least it has been in the past couple years. Nowadays conferences are attended from the comfort of our closet home-office. Although there are undeniable advantages in not being in the USA (please keep me out of there!), Sadia wonders: How to stay awake until 3am …[Read More]

The Sassy Scientist – Bend Or Break. Or Boost?

Ruggero has travelled a tough PhD journey. Foraging for his last bits of energy to continue onward on the treacherous odyssey of academia, he murmurs: How can I (re)gain some confidence after it has been shattered during my PhD? Dear Ruggero, Ciao bello. Does that help? Never mind. Just kidding. I cannot imagine how badly …[Read More]

The Sassy Scientist – The Doctor Is In

There are no stupid questions. How many times have we heard that from colleagues and in classrooms? Obviously an exceedingly sizeable chunk of our community does not receive stupid questions often enough. Even silly questions have their merits though, and obviously they deserve an answer, at least to avoid them being asked in the future. …[Read More]

Why do some slabs stagnate?

Why do some slabs stagnate?

Mechanisms for stab stagnation are essential for understanding the mantle circulation patterns. This week, Diandian Peng, a graduate student from University of Illinois explores how dynamic pressure gradients can pull the slabs sideways stagnating them at the Mantle Transition Zone. Seismic imaging provides critical constraints on the structure and evolution of subducted slabs. Numerous tomographic …[Read More]

Angela is one to stress out just a wee bit every time a conference is right around the corner. It’s almost like she consistently doesn’t prepare in time. Ever so slightly concerned, her office mate asks: How last minute is too last minute when preparing for a conference? Dear Angela, Just take a breather and …[Read More]

Paleogeography and the Northern Hemisphere Oceanic Gateways

Paleogeography and the Northern Hemisphere Oceanic Gateways

Eivind Straume a Postdoctoral fellow at the Department of Geological Sciences within the Jackson School of Geosciences explores how the opening and closing ocean gateways have influenced the Earth’s climate in the past.   Changes in Earth’s geography due to tectonic plate motions and mantle convection influence climate evolution on geological timescales. Over millions of …[Read More]
