Current Earth Sciences Library News, No. 524, the Hot Lava edition

We’re in the media a lot right now!

It started when Jen Hoyal Cuthill & Simon Conway Morris’ paper in Proceedings of the National Academy of Sciences  got picked up by a vast number of media outlets, these are juts a few of them;

Then Martin Smith & Javier Ortega-Hernández’s Nature paper seemed to go viral, as above these are just a few instances of media coverage we’re getting

Below are two screen shots of the Altmetric results for these papers. Almetrics gathers data to showcase the impact & reach that papers may have, collecting the number of times a paper has been tweeted about, written up in a blog post, newspaper or other news outlet, cited, etc. You can see how your papers have done via your Symplectic page.

And then there’s Iceland, RIGHT NOW …

 

As most of you will know a number of department members are currently in the field in Iceland and the work they are doing is being reported. By the BBC on-line team, Simon Redfern was interviewed yesterday for Today  BBC Radio 4  from 01:43:55. Thorbjorg Agustsdott (Tobba) has written a piece for the University’s Research  features pages. You can keep up with the latest developments via Twitter by following Tobba –  ‏@fencingtobba and of course Simon @Sim0nRedfern who has just arrived there today I believe. Remember you don’t have to be on twitter to follow someone’s posts. And today the BBC is using even more of Tobba’s images.

Lots of pictures and news from those two.

Bob White has forwarded this message from Rob Green of the latest activity

You may have a text but a fissure eruption has just started at holuhraun to the south west of the closest deployed stations. It was very fortunate we deployed those extra three yesterday evening.
At around midnight there was a message on the tetra radio saying they had maybe seen something on a web cam at bardabunga so benni and Sveinbjorn went to investigate. The saw the fissure as soon as they approached dynguvatn and confirmed the eruption. We all then jumped in cars and drove over with steinni to meet up with Sveinbjorn and benni. Bit by bit we approached and at one point when the activity increased and the fissure was propagating north we retreated. It has been mostly white steam plumes coming off the vents but was a thick black ash plume at times. We have now turned back to dreki to get some sleep and have left Tobba and steinni to watch over the eruption for the first shift. Some of us will return in the morning. I have been taking notes during the eruption and Tobba will continue with this on her shift.
If you are interested they are copied below. They are very brief and blunt as they were written with cold fingers.

Eruption notes: Holuhraun eruption 29th August (night of 28-29th)

Visual confirmation of the eruption at around 00:30 by Sveinbjorn and Steinni.

Low activity at first. Lava flows were clearly visible on arrival at 1:30 emanating from a fissure. Just a gentle effusive eruption.

From 1:30 onwards the fissure appeared to extend south gradually and then eased off to a low rate until around 2:15.

Then there was a a rapid increase in activity at 2:15. The smoke went black and large fountains broke out. At the same time the fissure advanced north rapidly though distances are hard to estimate maybe half a km. It appears that the northern most vent is whiter steam and the southern vent is black. There are at least two distinct plumes.

The wind is taking thick plumes northwest and we can see the ash dropping out within 5km.

At 2:40 the southern most plume was the most active and the sounds are easily heard from our view point.

We can see 3 regions of activity at north middle and south. The fires along the fissure are less visible but there is some topography. Never the less the effusive activity has concentrated at certain points.

At 2:45 the southernmost vent is the most active with largish fire fountains and the southern most is lighter. I now think there are 3 plumes. North is white middle is black and south is grey but that plume is smaller.

Southernmost is the only one fountaining at 2:50. Northernmost white plume is getting wider and the sound is getting louder. Visible fires have reduced but plumes continue.

3:00 still 3 separate vents but they are only very faint glows. Northern one appears brightest against the white steam. There was a little splatter and fountaining on the northern one. The plumes density has reduced drastically so no longer phreatic. Plumes back to same density as arrival.

3:05 all plumes are white. Only visible active vent is the northernmost one which is bright but obscured by a dense white plume.

3:15
Activity is very low as we leave. All still have white plumes but much smaller. At this point website leaving for dreki to sleep. Steinni and Tobba will watch for the first shift while we sleep and then come back to swap.

Depart 3:20

Smartphone compass/clinometer apps. Warning from Nigel Woodcock

I keep being told that the complete answer to collecting field orientation data is a smartphone app such as FieldMove Clino. This does a lot of good things, BUT you should be aware of possibl errors. This is a regular topic of discussion on the Geotectonics discussion  group at https://www.jiscmail.ac.uk/cgi-bin/webadmin?A0=geo-tectonics. You can sign up there to see the FieldMove Clino thread beginning on 27/8/14, but the gist of the widely held concerns is in the post below from Richard Jones at Geospatial research at Durham. I’m sure that we will get reliable app/smartphone combination within a few years, but be careful in the meantime.

“We have carried out quite a lot of systematic testing of the suitability of iPhones as compass-clinos for measuring geological planes – and we have experienced very mixed results.

The good news is that ...

  1. we have managed to get good, repeatable results that are approximately as precise as a set of analogue compass-clinos (Silva liquid filled housings, double spirit-level, no electronics).
  2. once we’re up and running, using an iPhone is much quicker than any analogue compass-clino we’ve used; so ideal for taking large numbers of measurements from a single sampling site (e.g. fracture transects).
  3. we’ve now taken many, many thousand measurements with iPhones that we believe are within acceptable precision.

The bad news is that …

  1. if we’re not very rigorous in setting-up and calibrating the devices, we usually get randomly bad results.
  2. even if we are very careful, the iPhones sometimes don’t self-calibrate properly – so we always cross-check the iPhone against an analogue compass-clino before and after a measurement session.
  3. there’s no obvious way of examining the device itself to see whether it’s likely to be functioning correctly – you must have another device with which to compare it.

So personally, I’m extremely sceptical of the general validity of any orientation data that have been collected with smartphones – unless the user has documented their calibration procedure carefully, and that the calibration has not relied wholly of the device’s own calibration [… or until someone has documented why this isn’t necessary].
Based on this, I’d also recommend that any orientation data that are published (or form the basis for interpretations that are published) include a statement on the equipment and method used.”
