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 …[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]. …[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 …[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 …[Read More]
Biochar is a carbon rich product of biomass pyrolysis, a process where biological material is exposed to high temperatures, in the absence of oxygen, to cause the decomposition of that material into various chemical and physical components. By going through this process, biochar can be a valuable soil additive and a carbon sink with a …[Read More]
The earthquakes’ occurrence on the planet Earth is largely considered synonymous with disasters and people generally perceive geological faults as a threat to life and belongings. However, there are exceptions since a small community of earthquake researchers relate the occurrence of earthquakes with the lithospheric plate interactions where movement on faults causes earthquakes. Therefore, my …[Read More]
Ravi is done with his research, mentally. As he muses on a potential departure from academia – awaiting an unhackneyed sense of perspective – he asks: I want to leave academia! Where do I go? Dear Ravi, I am sorry to hear you’ve given thought to a termination of your academic career. After years of …[Read More]
Today marks the centennial of the birth of Marie Tharp, the person responsible for creating the first map of our planet’s ocean floors. Though her work was underappreciated at the time of its publication – mainly because she faced many significant barriers due to her gender – her maps ended up being instrumental evidence in …[Read More]
Marie Tharp (July 30, 1920 – August 23, 2006) would have turned 100 on this very day and she continues to live through her legacy of having mapped the world’s oceans. Similar to famous painters, some of whom only gain appreciation after their death, Marie Tharp is one of the most underappreciated scientists in the …[Read More]
