Geoscience for the Future with Dr Natasha Dowey

The Geosciences are at the forefront of the fight against climate change. It is Geoscientists who discovered it and explained it, and it is Geoscientists who work to understand it and its consequences. Geoscientists undoubtedly will be amongst those who will lead us to the solutions. However, it often seems that Geoscientists are solely associated with the extractive industries, a damaging false p ...[Read More]

The Sassy Scientist – Sterling Subduction

The Sassy Scientist January 29, 2021

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]

Janet Vida Watson (1 September 1923 – 29 March 1985): The woman who could translate the story of Precambrian rocks into a crystal-clear message

Anouk Beniest January 29, 2021

On a late summer day in September 1923, Janet Vida Watson was born. With a father working in palaeontology and a mother who did research in embryology until her marriage, Janet grew up with science all around her. She went to South Hampstead High School, known for its science teaching and continued her education in General Science at Reading University. She graduated in biology and geology in 1943 ...[Read More]

The acidity of atmospheric particles and clouds

Havala Pye January 27, 2021

Many of us learned about acidity, or pH, in high school chemistry. We learned that acids like HCl could dissociate into H+ and Cl- and the activity of those H+ ions defined the acidity. In the atmosphere, the same basic definition of acidity, or pH on the molality scale, applies to aqueous phases like suspended particles and cloud droplets. Atmospheric acidity regulates what kinetic reactions are ...[Read More]

Thermodynamics and Geodynamics: The perfect couple?

Bob Myhill and edited by Menno Fraters January 27, 2021

In preparation for Valentines day, Bob Myhill explores the potential for close partnership (and even love?) between the geodynamics and thermodynamics communities. Much of Earth and planetary science relies in some way on thermodynamics. This is not a surprise; the elegance1 of its premises makes thermodynamics a robust starting point for many investigations, and the number of thermodynamic applic ...[Read More]

Earthquake Watch December: Petrinja Mw 6.4

EGU Seismology ECS Team January 25, 2021

What we know On December 29, a strong earthquake Mw 6.4 hit Petrinja at 12:20 CET, a town located in Central Croatia. This event is the largest onshore earthquake rupture in Central Europe since the M 6.5 Norcia earthquake occurred in 2016 (e.g. Scognamiglio, 20181) which killed 299 persons and 4,500 became homeless. Recent reports on the Petrinja quake suggest seven fatalities and heavy damages o ...[Read More]

Features from the Field: Shear Zones and Mylonites

Samuele Papeschi, Sandra McLaren and Hannah Davies January 25, 2021

The San Andreas Fault in California, the Alpine Fault in New Zealand, or the Main Frontal Thrust in the Himalayas are some of the most famous and largest fault zones that accommodate the relative displacement between two adjacent crustal blocks. Such faults, however, represent only the shallower expression of something much bigger: a crustal shear zone. In the first 10 kilometers or so of the crus ...[Read More]

Advances in earthquakes forecasting pass through machine learning

Gabriele Amato January 25, 2021

In today’s interview, we meet Dr Fabio Corbi, a researcher at IGAG-CNR, the Institute of Environmental Geology and Geoengineering of the Italian National Research Council. Fabio has experience in analogue modelling of megathrust earthquakes and he is currently exploring the potentiality of machine learning in this research field. Hi Fabio, would you briefly tell us about you and your career? ...[Read More]

Atmospheric Rivers: A blanket for Antarctic winter sea ice

Diana Francis January 22, 2021

The mysterious appearance and disappearance of the Weddell Polynya, a giant hole in the sea ice cover, has long puzzled scientists. Recent work reveals that the polynya is initiated and maintained by gigantic and formidable atmospheric currents: atmospheric rivers! Read on to find out more… Each year, approximately 15 million square kilometers of ice forms in the Southern Ocean around Antarctica d ...[Read More]

The Sassy Scientist – Welcome to Hotel California

The Sassy Scientist January 22, 2021

Congratulations Glenn! You survived your socially distanced PhD defence and after three months in your mum’s spare room you are raring to go, chomping at the bit, and approaching the start line for the next stage of your academic career. Having spent the last eight years in education, it’s time to start a new job! What should I do on my first day at work in a new place? Dear Glenn, Whe ...[Read More]
