What’s up? The Friday links (62)

What happened in our world of geosciences last week? What news did you miss? What paper to read on the weekend? Here’s a roundup of last week. Today is Friday and here are your links!

Our dear fellow Curiosity (the NASA Mars rover) finds clues to how water helped to shape the Martian landscape with these nice photographs. And some research, of course. The Curiosity geoscientists are now making good progress in solving the mystery of Mount Sharp.

“We found sedimentary rocks suggestive of small, ancient deltas stacked on top of one another, Curiosity crossed a boundary from an environment dominated by rivers to an environment dominated by lakes.”
Sanjeev Gupta, Imperial College in London

 

Metageologist from All-geo wrote an article on Seismology in space and covers moonquakes, marsquakes and starquakes. However, when I came to read about marsquakes, I realized there was some part missing: paleo-! If I recall it correctly, there was an article by Gerald Roberts (Birkbeck University of London) in JGR two years ago and some discussion in Nature Geosciences on paleo-marsquakes. Highly interesting reads!

 

And again, outer space! Quite extraterrestrial this week, right? Rosetta’s comet a.k.a. 67P/Churyumov-Gerasimenko adds to the riddle of Earth’s oceans. Being all about that Deuterium, ESA findings rule out that neither Kuiper belt comets nor Jupiter-family comets contain solely Earth ocean-like water, and add weight to models that place more emphasis on asteroids as the main delivery mechanism for Earth’s oceans. Here is also the related Science paper.

 

The Geological Society of London blog have an geoadvent calendar – and they turn over the geolsoc blog to four weeks of festive geological musings. Door no. 6 was on four geologists you didn’t know were geologists. Let them surprise you!

 

See this video on a raindrop impact on a sandy surface. I really like the third one for some reason:

 

Ontario Geofish had some thoughts on Earthquake water, which is spare water jugs you should alwas keep in EQ-prone areas for the case of an earthquake and associated broken water pipes. And also for the occasional excavator mishap…

 

On Google+, Christoph is sharing some nice photos of his Greece field trip right now. (All I was thinking was: A field trip to Greece in November?! Poor students! They are missing the cherry on the great Greek geology cake: having a swim in the sea after a long field trip day!) Or are you guys swimming anyways?

 

Speaking of social media, here is what all the paleoseismicity.org authors posted on our Facebook and Google+ walls this week:

 

The city of Los Angeles is addressing their greatest earthquake vulnerabilities proactively and strategically, and released an informative report on their action plan: to fortify buildings, water system and telecommunications networks. Click here to read the full report.

 

A new disaster movie called “San Andreas” with Dwayne The Rock Johnson will hit the theatres in 2015. It will be on California earthquakes! Well, somehow. And somehow a lot of commenters expected a Grand Theft Auto movie rather than what seems so be another rendtion of what we’ve seen in 2012. Watch the trailer:

 

Have a nice weekend!

loves finding and exploring faults using remote sensing and shallow geophysics. No matter if slowly active, buried or just undiscovered! He is studing neotectonics in the Gobi desert at RWTH Aachen University.

    Actually, the most brave students did swim! And currently we’re just a few kilometers away from the hot springs of Thermopylae…
