Geoblogosphere Call to Arms: The Wikipedia Mantle Page
The geoblogosphere is fantastic. We tweet (a lot now), we have carnivals and we even podcast once a fortnight. One thing we don’t do, though, is pool our combined centuries worth of geological knowledge in unified, constructive ways. At least not all that often.
I would like to make this post a call to arms of sorts to all geobloggers and internet-savvy geologists out there to help with something. This particular page, Wikipedia’s entry on the mantle, is an absolute shambles. Not only are things like the Mohorovičić discontinuity only mentioned in passing without much description:
The top of the mantle is defined by a sudden increase in seismic velocity, which was first noted by Andrija Mohorovičić in 1909; this boundary is now referred to as the “Moho.”
(The page on the Moho is equally as vauge), but the figures, links and some of the references and suggestions in this page are simply stupid. Look at this bit of the extremely brief section on temperature:
Modern observations suggest that the mantle is cold.[15][16][17][18][19]
The mantle of Mars is also cold.[20]
This has very serious implications for those who believe the mantle is convecting hot fluid.
That has a very serious whiff of the EEdiots about it. Especially considering that every single reference given about the “cold mantle” is either in regards to an underlying section of the equatorial Atlantic MOR being colder than expected, or other areas of other MORs or spreading regions being cooler than expected (for the record, references 16 and 17 are the same). Not a single one of those references suggests the mantle is cold. The reason being that the mantle isn’t “cold” (whatever that means anyway, cold compared to what? Very unscientific). Any layperson reading this page would, however, be left with the impression that there’s serious debate regarding whether the mantle can flow at all.
I hereby kindly request that anyone out there with sufficient expertise in the mantle or associated sciences to please help in righting this travesty. I’m not asking for this to be done today, but over the next year we should endevour to pretty much rewrite this entire Wikipedia entry (lest the EEdiots take it upon themselves to do it for us and misinform the public even further). Wikipedia is fickle, however, and the formatting can be difficult to master, so getting a grasp on it now would be advantageous if you intend to contribute.
I’ll be doing some of my own research and clean-ups, but it’d be great if other concerned parties could help out too. After all, we blog about our science because we want to inform the layperson about how cool it is and to advance public awareness. Ensuring the go-to website for basic scientific facts is accurate can only help our cause.
