Flash Wedge Meme!


In the spirit of experimenting, let’s try this: find an engaging geoscience link you’ve come across in the last day or two that you want to share with the geobloggosphere.  You may, but don’t need to, write anything.  It might be a piece you’ve written for your own blog, a news story, a comic or a video.  The only limitations are that it should be relevant to the geosciences (not necessarily geology), it should be broadly accessible (if there’s a paywall or I can’t get to it, I won’t include it), and it must be SFW.  I’ll check them out, write a brief summary, pluck a picture if the mood strikes (pictures not necessary, though) and post it at Outside the Interzone, updating as links come in.

To be clear, all you need to do is 1) find an engaging geoscience-related piece anywhere on the web, 2) make sure it passes the limitations above, and 3) drop a link in the comments on this post.


To answer commonly asked questions, no, you don’t need to be a professional or knowledgeable geologist.  No, you don’t need to be a “member” of the geobloggosphere, though if you’re not but you DO have a blog, please link that too, or give me it’s name so I can back link you.  Yes, you do need to have internet access and a pulse.  That is all.

Just FYI, and for my own clarity of mind and organiztion, here’s a to do list for The AW site:

  • update participants and host list links
  • bring last two wedges from TC and DB on site
  • consider adding a new page or two to create a better forum for discussions and ideas regarding the AW.  I’d like to work back to the original layout of the main AW page as the place where past editions of the wedge are posted, and take discussion about the wedge elsewhere.
  • other?

Comments and ideas welcome.

    Wooster Geologists give a presentation about the Haiti earthquake. A lot of it is old news for geologists, but slides 21, 22, 23, and 50 struck me as new information, at least to me.

    I just read, via Wired Science, the following report on sand dunes and sand grain movement on Mars:


    Now, I’ll obviously have to read the orginal paper, but the web report is somewhat mysterious. There are many questions surrounding the differences in dune formation on Earth and on Mars – gravity, wind velocity, atmospheric density, and so on. But the report describes as novel, “a kind of billiard-ball effect in which one sand particle knocks the next one into motion. ‘It’s much easier to keep this process going than it is to start it in the first place’ ”(in the words of the researcher).

    This is the process of saltation and Bagnold, in his 1941 classic work “The Physics of Blown Sand and Desert Dunes” described, from field and wind tunnel experiments, how the threshold wind velocity for keeping the process going is lower than that for starting it. The author of the paper describes saltation as “sand blowing” which is a gross over-simplification.

    I must be missing something, or, perhaps more likely, the attempt to translate the science into a press release has simply lost the plot.

    Any comments/clarifications/explanations – or just help?
