#mineralmonday : gadolinite-(Y)

#mineralmonday: your weekly* dose of obscure mineralogy, every Monday** [*not guaranteed; **or possibly Tuesday-Sunday] What is it? Gadolinite-(Y),Y2FeBe2Si2O10 What’s it made of?: It’s a silicate (a mineral containing silicon (Si) and oxygen (O)) also containing yttrium (Y), beryllium (Be) and iron (Fe). Yttrium is a rare earth element – somewhat of a misnomer as in general they ...[Read More]

Imaggeo on Mondays: Our QUEST for innovative tools to understand changing environments and climates

The photo shown here shows typical sampling work underground. You can see Ola Kwiecien and Cinthya Nava Fernandez, researchers at Ruhr University Bochum in Germany, collecting dripwater in New Zealand’s Waipuna Cave as part of a four-year EU-funded monitoring programme. Our research aims at developing innovative geochemical indicators that we can use to quantify changes in the hydrological system ...[Read More]

Climate Change & Cryosphere – Caucasus Glaciers Receding

Climate Change & Cryosphere – Caucasus Glaciers Receding

The Tviberi Glacier valley is located in the Svaneti Region – a historic province of the Georgian Caucasus. Between 1884 and 2011, climate change has led to a dramatic retreat of the ice in this valley. Other glaciers in the Greater Caucasus evolved in a similar way in past decades. We investigated glaciers and their changes both in-situ and with remote sensing techniques in the 53 river bas ...[Read More]

The Sassy Scientist – PhD angst

The Sassy Scientist – PhD angst

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. Iris asks: Will I ever finish my PhD? Dear Iris, Most researchers won’t admit to it publicly, but they all had doubts when trying to complete their PhD researc ...[Read More]

Challenging challenges in Earth science research at the EGU General Assembly!

Challenging challenges in Earth science research at the EGU General Assembly!

At the EGU General Assembly 2019 last month, if you walked through the dark basement and the most distant hallways of the convention centre,  into room -2.62 on Wednesday evening, you may have heard people introducing themselves followed by the words “… and I have a problem.” This may have sounded like a support group. In fact, if you had entered the room it would have been clear that you had just ...[Read More]

On the resolution of seismic tomography models and the connection to geodynamic modelling (Is blue/red the new cold/hot?) (How many pixels in an Earth??)

What do the blobs mean?

Seismologists work hard to provide the best snapshots of the Earth’s mantle. Yet tomographic models based on different approaches or using different data sets sometimes obtain quite different details. It is hard to know for a non specialist if small scale anomalies can be trusted and why. This week Maria Koroni and Daniel Bowden, both postdocs in the Seismology and Wave Physics group in ETH ...[Read More]
