Modelling the Vadose Zone…What fun!

Geosphere | 24 April, 2014
Sometimes our projects take stage and unexpected turns down pathways that we have no experience in whatsoever. My project on the input of Fukushima iodine-129 into groundwater has taken one of those turns. This is not a bad thing, but it is a time consuming one, as these deviations often are. However, instead of bemoaning my new lot in life as modeller of the unsaturated (vadose) zone, I thought I'd share a bit of what I'm doing. By the way, if any of you reading this have any experience modelling the vadose zone I'd love to talk in greater detail with you.

A culture of asking questions

Agile Geoscience | 24 April, 2014
When I worked at ConocoPhillips, I was quite involved in their knowledge sharing efforts (and I still am). The most important part of the online component is a set of 100 or so open discussion forums. These are much like the ones you find all over the Internet (indeed, they're a big part of what made the Internet what it is -- many of us remember Usenet, now Google Groups). But they're better because they're highly relevant, well moderated, and free of trolls. They are an important part of an 'asking' culture, which is an essential prerequisite for a learning organization.

Geotalk: Steven Smith on fossil faults and fantastic faulting

EGU Geolog | 24 April, 2014
This week in Geotalk, we're talking to Steven Smith, a Lecturer from the University of Otago. Steven takes us on an Earth-shaking journey, explaining how ancient faults reveal what's happening under the Earth's surface and delving into the future of fault zone research.

Landslide losses – raising the profile in the USA

The Landslide Blog | 24 April, 2014
The two dramatic landslides of the last few weeks in the USA has undoubtedly raised the profile of this natural hazard.  The Oso landslide in Washington State remains high on the news agenda, and was even visited by the President earlier this week.  Meanwhile, the fascinating East Gros Ventre Butte landslide in Jackson Hole continues to creep, with devastating impacts on the family who owned the house at the crest of the slide.

European Geosciences Union – General Assembly 2014 (Part 3)

A couple of weeks ago we outlined the ways in which we will be participating in the EGU General Assembly taking place in Vienna next week.  We're currently asking a few of the GfGD team who are attending to give us an outline of the sessions that caught their eye and to tell us more about their roles at the event. Yesterday Jane Robb outlined a number of sessions, and today it is the turn of Rosalie Tostevin.

Earthquake rates inferred from active faults and geodynamics

Paleoseismicity | 23 April, 2014
Vanja Kastelic and Michele M. C. Carafa (INGV, L'Aquila, Italy) recently published an article in the Bollettino di Geofisica Teorica e Applicata (an international journal of Earth sciences) entitled "Earthquake rates inferred from active faults and geodynamics: the case of the External Dinarides." This article covers the area affected by the earthquake of Ml 4.7 (Mw 4.6) occurred on April 22, 2014.

Happy Earth Day from the Philippine Sea!

JOIDES Resolution Blogs | 23 April, 2014
I hope you all had an excellent Earth Day on April 22nd. Did you all hug a tree, ride a bike or read the Pale Blue Dot monologue by my main man Carl Sagan? I tried to hug a tree, but my arms wouldn't reach (clearly I'm awesome at jokes). Although I'm really far away from land, being out at sea really felt like I was a part of the 'Blue' in Blue Marble.

Asteroid 2014 GJ45 passes the Earth.

Sciency Thoughts | 23 April, 2014
Asteroid 2014 GJ45 passed by the Earth at a distance of 10 190 000 km (roughly 26.5 times the average distance between the Earth and the Moon) at about 11.35 am GMT on Thursday 17 April 2014. There was no danger of the asteroid hitting us, though were it to do so it would present a realistic threat. 2014 GJ45 is estimated to be between 36 m and 110 m in diameter, and an object towards the upper end of this range would be predicted to be capable of punching straight through the Earth's atmosphere, impacting the planet's surface a causing an explosion roughly 2500 times as large as the Hiroshima Bomb. Such an event would create a crater around 1.5 km wide as well as causing devastation over a much wider area, and resulting in climatic effects that would probably last for several years.

A model of planetary formation that explains the Earth’s lithophile element depletion.

Sciency Thoughts | 23 April, 2014
CI chondrites (Carbonaceous Ivuna Chondrites; Ivuna from the Ivuna Salt Flats in Tanzania where the first meteorite of this class was discovered) have a chemistry that closely matches that of the Solar photosphere, and are therefore widely taken as a model for the abundances of elements in the nebulae from which the planets condensed. The Earth is considerably depleted in lithophile elements ('rock loving' elements; elements that remain close to the Earths surface - lithosphere - as they bond easily with oxygen; mostly f and s block metals, plus the lanthanides) compared to these meteorites, something which planetary scientists have struggled to explain.
