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]
Although more commonly associated with the west coast of the United States, if you visit Cabezón de la Sal in Spain you may come across a stand of giant redwood trees or Sequoia. Around 800 trees were brought to Spain in the 1940s, so are still very young, but even at their young age they are still around 40 meters high! Sequoia groves, as well as being awe-inspiring to look at, provide a uniquely ...[Read More]
A wide variety of webinar sessions were streamed during EGU 2020’s Sharing Geoscience Online, including all of the Great Debates and Union Symposia. The sessions were very well attended, with some sessions having over 700 participants. An extremely high level of engagement meant that in many cases not all of the participants’ questions could be answered in the available time. Union Symposium ...[Read More]
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]
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]
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]
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]
Too envious to watch Netflix’s Selling Sunset? Gone through the top 5 geodynamic movies? Lock-down vacation too boring for words? In need of useful procrastination? Search no longer! We have compiled an extensive list of online webinars and speaker series that were already active pre-Corona or saw the daylight during the pandemic to stay in touch with our colleagues both abroad and next door ...[Read More]
Jesse Zondervan picks his favourite posts from geoscience and development news which cover the geology for global development interest. Here’s a round-up of Jesse’s favourite selections for the last four months of 2020: In the words of Sarah Derouin at AGU’s Eos “some geoscientists have seen their productivity grind down to plate tectonics speeds while the pandemic rages on”, but some environmenta ...[Read More]
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]
