This week’s photo is a beautiful example of geochemistry in action. Briefly, travertine, which is composed of CaCO3 is often precipitated at hot springs as they emerge from the ground forming these gorgeous terraces. The reason for their formation is Henry’s gas law in action which states “the solubility of a gas in a liquid is …[Read More]
Photo of the Week # 41
I am furiously writing my Ph.D thesis at the moment. I am close to submitting. I swear! Although, everyone I know says I sound like a broken record when I say this. Anyway, while I have been doing all this writing I haven’t had much time for blogging, for which I apologize. However, in the …[Read More]
GeoPoll: What should we do with radioactive waste?
I don’t think it is any secret that the world is facing an imminent energy crisis. We are trying to generate more power than ever before, but at the same time, we now realize we have to do it in a sustainable way that does not harm the environment or exacerbate any existing issues such …[Read More]
Shades of L’Aquila: Italian Geochemists avoid Huge Miscarriage of Justice
On rare occasions I hear about a story that must be told. This story is one of those and I feel that it deserves attention from the broader geoscience community. We have all heard of the L’Aquila verdict against the Italian seismologists concerning the devastating earthquake in 2009. If you haven’t, read these articles by Chris Rowan. At the time …[Read More]
I’m on TV!!
About a year ago I was asked to appear as a guest on a kids television show about rocks and minerals called Finding Stuff Out. I was asked to come an talk about rocks, minerals, geology in general and how I got interested in geology. The show is for 8-10 year olds and it is …[Read More]
GeoPoll #3 – What got you interested in geology?
After a bit of an opinion hiatus I am back with the third geopoll. Every day I go to work at a university department filled with geologists. All of us are tackling different questions, but in the beginning we all started at the same place. Namely, not knowing anything about geoscience. In my conversations with colleagues over …[Read More]
The Search for Ithaca
This post unifies two of my absolutely favourite topics: geology and classical Greek history. I have always had a soft spot for the classics. In fact, when I started my undergrad I was planning on doing a double major of geology and classics. I decided to focus on geology, but I have not lost my …[Read More]
Guest Post: Dr. John W. Jamieson – Using seafloor mapping to find missing Malaysia Airlines flight MH 370
On March 8th, 2014, Malaysia Airlines flight MH370 disappeared while en route from Kuala Lumpur to Beijing. Evidence from satellite tracking suggests that the aircraft may have crashed into the Indian Ocean several 1,000 kms west of Australia and this is where the search is now focused. No debris or oil slick related to the …[Read More]
GeoPoll # 2 – What geologic attraction would you like to see most?
The first geopoll was a huge success!! I was completely floored by the overwhelming number of responses and the time and care people took to give their opinion. The results of the last poll showed, overwhelmingly, that field work is of paramount importance to a good geology education. In fact, the top two choices with 160 …[Read More]
GeoPoll # 1 – What does a geology education need?
I’d like to inaugurate a new series of posts, that will pop up on a semi-regular basis, namely, whenever I feel like it. Since day 1 of this blog, even way back in my pre-EGU days, I have tried to encourage participation from readers. To date, the only way for you to engage with me …[Read More]
