The Indian Ocean Geoid Low at a plume-slab overpass

The Potsdam gravity potato

In this week’s News & Views, Postdoc Elodie Kendall from GFZ Potsdam shares with us recent work on the mantle structures that could explain the Indian Ocean Geoid Low.           What is the geoid, what does it look like and what can it tell us about mantle structure? The geoid is a model of the shape of the oceans’ surface if only gravity and Earth’s rotation act ...[Read More]

The Sassy Scientist – #WriteProperly #NoMoreAcronyms

Nerea cannot get enough of writing papers, reports and proposals. However, actually reading scribbles, especially those jotted down by (under)grad students, leaves her a histrionic gasp. She thus ejaculates: LLSVP or LLVP or LL(S)VP – why must we prolong the acronym wars? Aupa Nerea, The Americans. No doubt. It has got to be them. Just like so many things, they’ve ruined that beloved English ...[Read More]

Rayleigh-Taylor instability in geodynamics

Rayleigh-Taylor instability in geodynamics

Flow against gravity is a common feature in the geodynamic phenomenon. In this week’s Geodynamics 101, Dip Ghosh from Jadavpur University Geodynamics Lab will explain the fundamentals of Rayleigh-Taylor instability: A key to understanding the anti-gravity flow. It has long been realized that most of the geodynamic processes can be described in terms of slow viscous flow. Thus, like many othe ...[Read More]

The Sassy Scientist – Sterling Subduction

Fausto is very much preoccupied with subduction zones. The omphalos of his working life, or better yet, his paltry existence, he lacklusterly focuses on a single subduction zone. A proclivity for narrow-mindedness, surely. Yet there are ever so many to rejoice in. He thus warbles: What is your favourite subduction zone? Dear Fausto, I can only think of that one little special place deserving the p ...[Read More]
