Iron volcanism on metallic asteroids?

Metallic asteroid

This week, Francis Nimmo, professor in the Department of Earth and Planetary Sciences (University of California Santa Cruz), tells us about volcanism on metallic asteroids! Around and after the formation of the solar system (4.5 billion years ago onwards), volcanoes on some of the gigantic bodies of the asteroid belt might have erupted … iron. Explanations. One way in which we can learn abou ...[Read More]

Imaggeo on Mondays: Recreating monster waves in art and science

Featured in this blog post is a collection of images that gives a picture-perfect example of life imitating art. The photos in the left column are three consecutive still frames of a breaking wave that scientists generated in a lab environment at the University of Edinburgh in the UK. The pictures in the centre and right columns show the same wave images, but now superimposed with the famous 19th ...[Read More]

Surviving in cold environments: from microbes under glaciers to queer scientists in the current social context

Surviving in cold environments: from microbes under glaciers to queer scientists in the current social context

On the 5th of July we will celebrate the International Day of LGBTQ+ (lesbian, gay, bisexual, transsexual, queer, and people that do not identify themselves as cis and/or straight) People in Science, Technology, Engineering, and Maths (STEM). Many people will ask: “Why is this day important?” Being a queer scientist in particular, and a queer person in general, can sometimes reminds us of how livi ...[Read More]

The Sassy Scientist – Jekyll: Mantle dynamics

The Sassy Scientist – Jekyll: Mantle dynamics

Every week, The Sassy Scientist answers a question on geodynamics, related topics, academic life, the universe or anything in between with a healthy dose of sarcasm. Do you have a question for The Sassy Scientist? Submit your question here. Senna asks: I’m torn between mantle dynamics and lithosphere dynamics as a research topic. Which shall I choose? Dear Senna, This is an easy one: mantle dynami ...[Read More]

What I learned from chairing my first EGU session

What I learned from chairing my first EGU session

By Emily Bamber (PhD Student, University of Manchester) At this year’s EGU meeting I was invited to co-convene the GMPV 5.7 session ‘Magma ascent, degassing and eruptive dynamics: linking experiments, models and observations’. At first, I felt nervous, as a PhD student who has so far only attended and presented at a few conferences. Afterwards I felt happy to be part of a session which presents cu ...[Read More]

It doesn’t work! (Asking questions about scientific software)

It doesn’t work! (Asking questions about scientific software)

Numerical modelling is not always a walk in the park. In fact, many of us occasionally encounter problems that we cannot directly solve ourselves, and thus rely on help from others. In this month’s Wit & Wisdom post, Patrick Sanan, postdoctoral researcher at the Geophysical Fluid Dynamics group at ETH Zurich, will talk about asking the right questions about scientific software. As an experienc ...[Read More]

Quality through Equality – tackling gender issues in hydrology

Quality through Equality – tackling gender issues in hydrology Results of a 1-day workshop organised by the University of Bristol’s Water Engineering Group “Science has a diversity problem” (Nature, 2019), and hydrology and the water sciences are no exception. For example, overall only 36% of all EGU medal awardees are female. With 31% of all nominations going to female researchers (Ka ...[Read More]

Imaggeo on Mondays: Robotics at the service of the polar science

This picture was taken in the Arctic in May 2018. It shows the unmanned marine vehicle Proteus in front of the tidewater glacier Conwaybreen in the Kongsfjorden in Spitsbergen in the Svalbard Archipelago. The front of tidewater glaciers is an almost vertical wall of ice standing over the sea where direct measurements are very critical due to the possibility of sudden fall of enormous blocks of ice ...[Read More]
