The boundary between the core and the mantle, 3000 km deep, is scattered with island/blobs of strange material. In this study, @CarlMartin_ uses seismic waves to image one of these beneath the mid Pacific. sciencedirect.com/science/ar…

Deep beneath Hawaii, on the boundary between the core and the mantle, sits a patch of weird material, about the size of France. This might be the root to the mantle plume and the volcanic hotspot creating Hawaii. The patch has been widely studied with transverse waves...

📢 Research Associate position in Global Seismology Interested to understand interplay between mantle phase transitions and mantle convection, and how we might observe the 'mantle wind'! Come join our team! with @johneclogite

@camcycle Is this a poorly placed post in the new Darwin Green development? I feel like it could all have been set back by a meter, creating less conflict with people waiting, and less of a hazard when dark.

Deep Earth Explorers can also escape out of a Mayan Temple!

An excellent PhD viva by Carl Martin! Followed by an amazing ice cream cake! Congratulations Dr Martin! @CarlMartin_

How can we map anomalies on the core-mantle boundary nearly 3000 km deep? @CarlMartin_ presents a fresh Bayesian methodology and its application to the anomaly at the base of the Hawaiian mantle plume and a 2-part paper. Part 1: academic.oup.com/gji/advance…

Me two weeks ago…

Parenting fail: 3-year-old wants me to help him find a duplo figure to drive his truck. The first three I find are deemed too small to drive a truck. I finally find a bigger one, but he exclaims: 'No, that is a mama. I need a papa to drive my truck'. Sigh!

This is post-viva Dr Stuart Russell examining the layering at the core-mantle boundary within the cake. Congratulations to an excellent PhD thesis! Thanks to @jess_irving for joining us in the science. And to Sebastian Rost and David Al-Attar for grilling him.

📢Postdoc opportunity in seismology! Keen to uncover the mantle dynamics beneath Iceland? Keen to work on ocean bottom seismic data? Sergei Lebedev and myself offer this in Cambridge jobs.cam.ac.uk/job/40608/ Please share!

Littlest one was quite curious about her first conference. Can also spot @seismo_koel with her little one there! Was lovely to travel and manage together (with help of my father as well).

Nice to catch up with science, colleagues and the Deep Earth Explorer Team at the Gordon Conference on the Interior of the Earth. Maternity leave is almost ending.

Some mistakes add up to this…

The observations are very prevalent in regions of hot upwellings though.

2- and 0-year-olds made it to their first march! Hoping for a cycle friendlier cleaner Cambridge in their future! #Yes2CamSTZ
