The Sassy Scientist – Snobs Away!

The Sassy Scientist – Snobs Away!

As lockdown eases in many places, Stefan is beginning to think of an academic future away from his sofa. He asks the question: How much does university ranking matter when choosing a PhD position? Dear Stefan, Choosing a PhD program is tough. It’s a bit like getting married: for better or worse, until death us do part, regardless of the toe nail clippings on the table or refusal to ever take ...[Read More]

TS Must-Read – Hubbert and Rubey (1959)

TS Must-Read – Hubbert and Rubey (1959)

“The Role of Fluid Pressure in Mechanics of Overthrust Faulting” by Hubbert and Rubey is a “groundbreaking” article from the end of the 1950s. It’s a remarkable piece of research, written in an old-fashioned way, for modern standards. Many ECS that may not have read the original paper yet are certainly familiar with its textbook content. Let’s go quickly through it!   The article, as a key po ...[Read More]

Xavier Sánchez-Vila (2020 Henry Darcy Medallist) on these strange times and the usefulness of scientific thinking

The EGU 2020 Henry Darcy Medal of the EGU Division on Hydrological Sciences was awarded to Xavier Sánchez-Vila in recognition of his innovative theoretical work and practical solutions regarding aquifer characterisation, subsurface solute transport processes and managed aquifer recharge. Given the online EGU 2020 GA, the medal lecture was however postponed to 2021. We then invited Xavi to write so ...[Read More]

Research Cruise in times of COVID-19

Research Cruise in times of COVID-19

While the whole world is on stand-by we are in the middle of the North Atlantic and I want to explain you, why! During those crazy times cruise planning also slightly changes. The original plan was to depart and arrive back in Reykjavik which would have only included a short transit to our research area, the OSNAP East section. In the end we had a 9 day transit from our homeport Texel, Netherlands ...[Read More]

The Sassy Scientist – The Burning Question

The Sassy Scientist – The Burning Question

In the climb on the academic pyramid, Antonia wonders: How do you tell someone “you have not done enough to be included in the co-author list”? Dear Antonia, *arranges Yoda robe*: Big questions you have! Right place you came! I am sure you are not the first or the only scientist with that question. Since I feel generous today, I will leave here a template e-mail you can all copy and pa ...[Read More]

Features From the Field: Pencil Cleavage

Features From the Field: Pencil Cleavage

This edition of ‘Features from the field’ is brought to you by Sandra McLaren, a senior lecturer at the University of Melbourne. She will be talking about type of rock formation called “Pencil Cleavage” so called because it looks like pencils. Sandra even has a small collection of pencil/crayon shale which is the cover image of this post. I have seen quite a range of differ ...[Read More]

Ask us (almost) anything: Were Chixculub and Deccan related?

Doc Rock from twitter asks Has anyone investigated the hypothesis that the Deccan Traps basalt flows came after, and were the result of, the Chixculub impact event, based on the DT basalts being on the exact opposite side of Earth at the time of the event? For context, the Chixculub crater is buried under the Yucatan peninsula in Mexico, and resulted from a meteorite impact that is widely believed ...[Read More]

Breathing life into a d(r)ying lake in northwest Iran

Breathing life into a d(r)ying lake in northwest Iran

Lake Urmia, in Northwest Iran, was once the most extensive and permanent hypersaline lake (salinity >> of ocean) in the world. Since 1995, the lake water level has dropped about 8 m, shrinking to less than 30% of its original surface area and losing more than 90% of its water volume over two decades [1]. Unsustainable water management in response to increasing demand together with climatic e ...[Read More]

Why do mesoscale eddies disappear at ocean western boundaries?

Why do mesoscale eddies disappear at ocean western boundaries?

In the ocean, mesoscale eddies are everywhere. In fact, about 90% of the ocean’s kinetic energy is contained within these ubiquitous, ~100 km swirling vortices. We know how these eddies form, through a process known as baroclinic instability, where density surfaces are tilted too steeply and become unstable. What remains unclear however, is what happens to this energy when eddies die. This knowled ...[Read More]
