Hello everyone.

Sorry for the long hiatus here on goodSchist and on the podClast, I’ve been traveling to various places in Europe for the past month and I’m about to head out on the second leg of my long trip home later this morning with a flight to San Francisco.

This will, of course, bring about the long talked about San Francisco GeoBloggers in the Pub event that I’ve hinted at to various people over the last few months.

So, if you’d like to come along, have a few beers or drinks of various other types with geologists and geobloggers, and participate with a live recording of the podClast, here are the details you’ll need:

Date: Saturday the 25th of July
Time: from 1400 (2pm) onwards (podClasting from about 1500 I reckon)
Place: The 21st Amendment Brewery, 563 2nd St, San Francisco (Google Map)

If you’re intending on joining us for the podClast recording and you have an iPhone, it’d be really handy if you loaded a copy of the Griffin iTalk app (website here). It’s free and means we can have a few recordings going on at once for prosperity/volume levels. Also, if people could suggest topics for discussion in the comments section below, that’d be great too (although a free flowing discussion will no doubt ensue).

Hopefully see a reasonable group of you there.

This week’s podclast is the Geobloggers in the Pub episode. We talk about the KT boundary, including new research relating to it. Plus we lay into creationism in a pub-style chat fest.

The K-T Boundary and What Caused It

The paper we were discussing is by G. Keller et al. in Journal of the Geological Society, Vol. 166, 2009 [of London]. I can’t find the full name of the paper but I’ll keep looking.

Kim at All My Faults are Stress Related has a post on K-T extinction debates: cranky “skeptics” or reasonable science?

And the press release is available in various mass-media-filtered forms at Time, and the BBC.

Ethan Siegel’s Starts with a Bang has an article called What Wiped Out the Dinosaurs?, which is a superb run-through of the Chicxulub/KT impact. And you may want to read up on the Deccan Traps and how they relate to the KT extinction too. Also of interest, not because it explains the extinction, but because it’s another narrowly thought-out idea (or at least that’s how it’s been presented) is Insect Attack May Have Finished Off Dinosaurs which talks about the research from the book What Bugged the Dinosaurs?.

Creationism

You can look up Answers in Genesis yourself, as I won’t be linking to them, however the Talk.Origins Archive is a great place to look for basic questions and answers regarding the Evolution/Creationism debate.

Extra Note

The fossil of the seal ancestor is called the Pinniped, and information on the find can be found at the BBC and Eureka Alert.

Next Episode – Geoblogger in the Pub

We like to have a new episode of the podClast every fortnight. The next episode will be recorded at 1900 GMT on the 16th of May.

Italian Earthquake

The USGS has the raw details of the M6.3 earthquake.

Chris from Highly Allochthonous discusses the tectonic setting of the quake as well as the foreshocks and aftershocks.

Kim from All My Faults Are Stress Related talks about earthquake predicition, including that made by Iben Browning.

Ole from Olelog also discusses earthquake prediction in L’Aquila Earthquake – Followup.

Andrew from About:Geology calls the prediction irresponsible,  and so does the New York Times.

And the report from the BBC concerning the destruction that occurred is worth a look too.

Mt Redoubt

There’s a good summary of rticles regarding the previous set of eruptions from the podClast episode 10.

This is the picture Ron mentioned of the growing lava dome from the Alaskan Volcano Observatory.

Next Episode – Geoblogger in the Pub

We like to have a new episode of the podClast every fortnight. The next episode, however, will be recorded live at the Geobloggers in the Pub, in London on the afternoon of Saturday the 2nd of May. We’ll be drinking at the Cittie of Yorke, 22 High Holborn, London, WC1V 6BN from 2pm onwards. If you’re in the London area and would like to join in, check out this post for details (http://is.gd/tpFI).

On the first weekend of May I’ll be stomping around the mighty city of London and in between catching up with the 7 million kiwis who live there, I’d like to initiate the first Geobloggers in the Pub (calling it “Geologists in the Pub” would have set off my redundancy meter – but either will do). Before announcing official times and a location, I’d like to just get a show of hands from geologists or geo-interested persons who’d be willing to sit around a table in the mid afternoon in a pub in central-ish London on Saturday, May the 2nd.

Since it’ll be a podclasting weekend, I’m intending on doing a recording with whoevers there too, getting opinions on whatever geonews is around for 20-40 minutes. That’ll make it the first “live” podclast.

So, who’s up for drinks and some light conversation?

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.
