Behold, a new sunspot…

new_sunspot.jpg


The little fellow circled here (in the solar sense of “little” – it’s probably a few thousand miles across) appeared on the 4th January, and probably marks the start of Solar Cycle 24. A slight dent in those bold predictions of a prolonged minimum in solar activity, which would stop global warming in its tracks and put all of us tree-hugging CO2-obsessives in our place. Oh well.
This picture was taken by one of NASA’s two new STEREO satellites, but the new sunspot was also seen by the more venerable SOHO observatory.

Annoying misconceptions in Geology

For various reasons mostly beyond my control, I haven’t really had time to write an entry for for this month’s Accretionary Wedge, the theme for which is “(Un)Favorite Geological Misconceptions”. Fortunately, this very subject was the theme of a post from way back in the early days of ye olde blog. Since this was also a time when my readership wasn’t much larger than me (and I half expected it to remain that way), I feel quite justified in dusting it off, giving it some polish (since I have revisted some of these themes in later essays) and reposting my list of pet peeves. As for the ‘pie’ sub-theme, I’m with Julia: most good pies are savoury pies, and steak and stilton pies are the best of the lot. But I digress.

Nature Geoscience: cutting edge or consolation prize?

This month saw the launch of the first issue of Nature‘s latest specialist offshoot, Nature Geoscience. This is a monthly publication presumably designed to act as a clearing house for those contributions which don’t quite have the pizzazz to make it into the flagship.
Many scientists regard ‘Getting a Nature (or Science) publication’ as somewhat akin to finding the Holy Grail – or at least, their impact-factor obsessed departmental administrators do. As such, they are willing to put up with the quirks of the whole process – the whims of the Nature editors as to whether your opus is “sexy” enough to send out for review in the first place, the eye-wateringly tight word limit, which results in jargon-heavy prose with the clarity of Limpopo River water even for someone quite well versed in the discipline (with an additional trend nowadays for ‘Supplementary Information’ which would be more accurately described as ‘Quite Essential Information, Actually, Which Our Paper Does Not Stack Up Without’).
It’s certainly nice to see that Geology is considered to be important enough to have it’s own little Nature subjournal, and perhaps this expansion will give geologists not working on palaeoclimate studies (yes, we do actually still exist) with a bit more of a look in. The question is, will getting published in this offshoot have a similar cachet as mother Nature itself? More importantly, will administrators and research assessments see it that way? Additionally, although two stories in the first issue have got some coverage (see here and here, as well as two currently only available online (see here and here), it remains to be seen whether the media will pay much attention to stuff published in this particular journal.
What do people reckon? I’d also be interested to hear what people from fields with more established Nature offshoots (there’s a Physics one, a Genetics one and a Neuroscience one, amongst others) think of their impact and effectiveness.

So, what is the ‘Eye of Sauron’?

I was rather taken aback – in a good way – by the large number of responses to last week’s crater conundrum. Most people seemed to conclude that this structure in southeast Algeria:

was not, in fact, an asteroid crater. This was my feeling too, although I should stress that you shouldn’t regard that as an ‘answer’: it’s just my opinion, and is not based on anything other than my interpretation of the image above.

What on Google Earth?*

Jani has been exploring the Sahara Desert using Google Earth, and would like to know if this structure in southeast Algeria is a crater or not (it can be found at 22 48′ N 9 29′ E):

Before I give my thoughts, I’d be interested to hear what you good people think. Is it a crater? What evidence are you using to make your judgement?
