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 tomographi ...[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 years, continen ...[Read More]

Changing mid-degree: How did this Travelin’ Geo get here?

Changing mid-degree: How did this Travelin’ Geo get here?

It can be tough realising you’re not on the path you want to be on. This week, we have Leiaka Welcome from the Colorado School of Mines showing us how a change of heart led her to start her PhD journey. Currently on social media (Instagram Reel, TikTok), there is a video trend where users are editing a video of themselves in a scenario with an audio sound where you can hear a classic record scratc ...[Read More]

AGU times

AGU times

The first hybrid AGU meeting has everything one expects from the AGU – a long line to the registration desk and, a mile walk between the two ends of the conference hall, a large exhibit hall with NASA and their most-desirable calendars at the nexus, and our favorite poster hall to “network” with others – but with an added confusion, palatable emptiness, and no beer in sight! This week is a short b ...[Read More]
