California quake aftermath seen from space

The Trembling Earth | 24 October, 2014
As Northern Californians picked up the pieces and cooled their nerves on the afternoon of August 24th, just hours after being jostled or lurched from bed by the 3:20am magnitude 6.0 South Napa quake, a satellite whizzing by overhead snapped a shot of the scene. Check out some of these remarkable scenes within it that show damage, response, and recovery.

Open Access: Access to knowledge

EGU Geolog | 24 October, 2014
"Access to knowledge is a basic human right." Yet sadly as scientists we are often forced to operate in a framework in which this is not always the case. This week sees the celebration of the eighth Open Access Week, and whilst there have undoubtedly been many achievements by the Open Access (OA) movement since 2009, there is still a long way to go before mankind's basic human right to knowledge is restored.

Shark vs. CTD. Shark 1, CTD 0.

Land Beneath The Waves........... by Carol Cotterill

Any talk about submerged landscapes has the tendency to bring Atlantis to mind. However, the importance of our submerged landscapes and archaeology was brought to the fore at the Eurocean Conference in Rome earlier this month with the launch of a joi...

New book on Karst & Paleoseismology: Dynamic Tectonics and Karst

Paleoseismicity | 24 October, 2014
Springer has recently published the book Dynamic Tectonics and Karst in the series Cave and Karst Systems of the World, edited by our colleagues S. Shanov and K. Kostov. The book focusses on the influence of tectonic processes on the formation of karst and karst caves and one chapter is devoted to karst cave paleoseismology. The authors present studies from the Balkans, Cuba, and France.

Wooster’s Fossils of the Week: A pair of molded nautiloids from the Upper Ordovician of northern Kentucky

Wooster Geologists | 23 October, 2014
Two nautiloids are preserved in the above image of a slab from the Upper Ordovician of northern Kentucky. (I wish I knew which specific locality. This is why paleontologists are such fanatics about labeling specimens.) The top internal mold (meaning it is sediment that infilled a shell now dissolved away) has been covered in a previous blog entry. This week I want to concentrate on the nautiloid at the bottom.

Breast Cancer Awareness Month 2014: Ancient Mother Goes Pink

Jersey Boys Hunt Dinosaurs | 23 October, 2014
As you should know, October is national breast cancer awareness month.  The official color for breast cancer awareness is pink so for the past three years, in its honor, I have illustrated a different prehistoric animal in pink.  You may remember in 2012 Pachycephalosaurus was the first to rock the look and in 2013 Deinotherium was adorned in pink.  This year, I decided to paint a powerful meat eater which also shows evidence of being a mother according to a recent discovery of eggs in Europe.  I give you Torvosaurus in pink!

Partial Solar Eclipse from California (and What a Sunspot!)

Geotripper | 23 October, 2014
Wow. Just wow. Yes there was a partial solar eclipse today that was visible across much of the country, and yes, it was pretty spectacular. But what caught my attention was the huge sunspot. It is the first time I've ever seen a sunspot with the naked eye, and it was incredible in the zoom lens. I'm told that it is more than 90,000 miles across, the width of 12 Earths. Sunspots are essentially gigantic solar storms. They look dark, but they are simply a bit less bright than the rest of the Sun's surface.

Dinosaur Noses Are Cool

Laelaps | 23 October, 2014
Nearly a century ago, while working in the 75 million year old rock of Alberta, Canada, the professional fossil-hunter George Sternberg found a stunning skeleton. The remains belonged to a six-foot-long "bonehead" dinosaur named Stegoceras, and, best of all, the dinosaur's frame included a complete skull - a rarity for these animals. More often than not, a rough geological afterlife has reduced these boneheads - technically known as pachycephalosaurs - to little more than their sturdy skull domes. Stegoceras is an exception.

A Remarkable Fault Zone

Watch for Rocks | 23 October, 2014
There are certainly many extraordinary natural features to see in Yellowstone National Park, but I will bet there is one hillside in particular that might not have caught your eye. In fact, you could have driven right by this seemingly innocent slope on the road between Madison Junction and West Yellowstone without even giving it a second thought. After all, it looks just like any old slumping, eroding hillside.

Geo 730: October 23, Day 661: Craggy Headland

Outside the Interzone | 23 October, 2014
A bit farther south on the path from the Punchbowl proper, we had some lovely views of the seaside cliffs. Spots like this are glorious in heavy winter storms. However, even though the wind was gusting wildly on this day, the lack of a sustained direction meant there was not much in the way of heavy surf. Though as we'll see in a few days, there was enough in the way of swells to provide entertainment for a fair number of people.
