Six surprising reasons to be thankful for the sea

Deep Sea News | 24 November, 2014
The oceans provides us with most of the oxygen we breath, much of the food we eat, and even all the water we drink, which has passed countless times through the seas. There's no shortage of reasons to be grateful for our blue planet, but I though...

SVP Reflections

Saurian | 24 November, 2014
Well two weeks has already passed and that is SVP over another year and, on the face of it, it seems to have been yet another very well received meeting. From a personal standpoint I can honestly say that I enjoyed it again and, despite the amount of...

Alaskan ash in Ireland: context, implications and media coverage

Volcan01010 | 24 November, 2014
Long-range transport of volcanic ash was in the news last week, thanks to a recently published study by an international team of scientists, led by Britta Jensen and Sean Pyne-O'Donnell from Queen's University in Belfast. They showed that volcanic ash grains found in an Ireland had come from an ancient volcanic eruption 7000 km away in Alaska. This must have been an impressive ash cloud!

Planetary Volcanology field trip to the Pinacate Volcanic Field (November 22-23, 2014)

Active Tectonics | 24 November, 2014
I joined a field trip to the Pinacate Volcanic Field in Northern Mexico this past weekend. It was a part of the Planetary Volcanology class taught by Amanda Clarke and David Williams. It was beautiful and very interesting. I had never been there, but just stared at it on google earth:

Hypnopompic dunes

Through The Sandglass | 24 November, 2014
Between sleeping and awakening. We tend to think of the world's dune fields as fearsomely  awake, threatening and encroaching, creating vast sand and dust storms - and this is indeed the case for great stretches of our planet's sand seas, t...

Magnetic field of the Earth

Earth Learning Idea | 24 November, 2014
New ELI today 'Why won't my compass work on the other side of the Equator? - understanding the three dimensional magnetic field of the Earth'. People who take their magnetic compass from one hemisphere to the other are often surprised that it doesn't work in both. The activity uses this finding as a prompt to explain the three-dimensional nature of the Earth's magnetic field.

More Dust Devils

Looking for Detachment | 24 November, 2014
I often have occasion to see dust devils while traveling through Nevada, especially in the dryer months, but any time of year can afford the right conditions: a dry playa or dirt road (and other surfaces, read more here) and thermally unstable air. And so, while driving through the Fortymile Desert and about to pass by the Nightingale Hot Springs exit on I-80 back in early October --  the exit name combines two locations into one: Nightingale is from an old mining district and ghost town  in the Nightingale Mountains north of the freeway; Hot Springs is from the geothermal area at Brady's Hot Springs just south of the freeway -- I noticed a large plume of dust rising from the desert just north of the highway. I pulled off, securing a viewing point near a powerline road crossing the main road going north to Nightingale.

Non-bedding-parallel stylolites in Helderberg limestones, Corridor H

Mountain Beltway | 24 November, 2014
Saturday I posted some images of bedding-parallel stylolites from one member of the Devonian-aged Helderberg Formation (or one formation in the Helderberg Group; I'm not sure whose stratigraphy is preferable in this case). Here we are, further up-section, and you can see both bedding-parallel and non-bedding-parallel stylolites overprinting the limestone:

Imaggeo on Mondays: Glarus Alps

EGU Geolog | 24 November, 2014
Undoubtedly, the Alps are one of the best studied mountain ranges in the world. Appreciating their immense beauty and geological wealth can be difficult from the ground, given their vast scale and the inaccessibility of some of their more challenging peaks. Kurt Stüwe, along with alpine photographer Ruedi Homberger, set about changing this by undertaking the ambitious task of photographing the length of the Alps, from Nice to Vienna, in a small aircraft. The result is a compilation of stunning photographs that capture the magnificence of the Alps and contribute to a better understanding of their geological history.

Magnitude 6.8 Earthquake in Nagano Prefecture, Japan.

Sciency Thoughts | 24 November, 2014
The Japan Meteorological Agency (which also monitors seismic activity) recorded a Magnitude 6.8 Earthquake at a depth of 10 km in Nagano Prefecture on Honshū Island, slightly before 10.10 pm Japan Standard Time (slightly before 1.10 pm GMT) on Saturday 22 November 2014. Over 40 people are reported to have been injured, seven of them seriously, in the incident, which was felt across most of central Honshū, and over 50 homes have been destroyed. A series of aftershocks have been reported since the event, and rescue teams are still searching the remains of many buildings for further survivors.

New paper: How archaeology records extreme flood events in Oman

Paleoseismicity | 24 November, 2014
Our latest paper on coastal change in Oman deals with an extreme flood event that was recorded in an archaeological site in Ras al Hadd, at the easternmost tip of the Arabian Peninsula. We found multiple evidence for past tsunamis that hit Oman's coast in the past. Close to Fins, mega-boulders were thrown on a cliff by huge waves. Fine-grained sediments typical for tsunami action were found in the same area. Searching for further evidence, we came across the archaeological site of HD6 in Ras al Hadd. The archaeologists that were excavating this site told us about strange findings in the archaeological record - they encountered a layer that interrupted the otherwise continuous stratigraphy of the settlement. The bronze age fishing village is located very close to the coast only a few meters above sea level, a large tsunami could easily impact here.

Primitive camping and serpentinite

Magma Cum Laude | 23 November, 2014
There are field trips that make me very glad I drive a car with a reasonable amount of clearance, and my camping overnighter to the Los Padres National Forest south of Big Sur was no exception. Driving the Coast Ridge Road wasn't the most harrowing trip I've ever made, but it certainly merited the description of 'gnarly' that one of my camping buddies applied.
