X and mantle plumes: the deep quest

X and mantle plumes: the deep quest

Seismic discontinuities necessitates mechanisms that would generate them and therefore, help us better understand the internal structure of the Earth.  This week, Martina Monaco talks about the mysterious X-discontinuity — observed under several hotspots at upper mantle depths of ~ 290 km —and how it relates to the rising plumes. According to the Oxford Dictionary, only 400 words in the English la ...[Read More]

To go or not to go (to my PhD graduation)?

To go or not to go (to my PhD graduation)?

You’ve come to the end of your PhD and after years and years of hard work, one last question remains: “Should I go to my PhD graduation?”. This week, we have one of our editors Kiran Chotalia sharing her two cents after she finally attended her in-person graduation this year after it was delayed by the pandemic (TLDR; definitely go!). In March 2020, after four and a half years of hard work, meetin ...[Read More]

Join in our Mag-netZ !

For better or for worse, online seminars have stealthily become part of our routine. This week, Daniele Thallner from the University of Florida, “attracts” our attention to a seminar series on geomagnetism and geodynamo modeling — Mag-netZ! The 2022 season of the MagNetZ seminar series is live! The MagNetZ (Magnetic NetworkZ) online seminar series was started in early 2020 to serve as ...[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 tomographi ...[Read More]
