Judith Curry responds … sort of (v2)

Open Mind | 3 July, 2015
Well, Judith Curry has "responded" to my last blog post ... sort of. Here's what she has to say about it: Tamino's argument is essentially a quibble about how heat waves are defined, there are various definitions https://en.wikipedia.org/wiki...

Wollangambe River severely affected by mine runoff following wall collapse at Clarence Colliery.

Sciency Thoughts | 3 July, 2015
The New South Wales Environmental Protection Agency is assessing damage to the Wollangambe River ecosystem near Lithgow in the Central Tablelands of New South Wales, following the collapse of a wall of mine waste at the Centennial Coal operated Clarence Colliery on Thursday 2 July 2015. The river is showing signs of being clearly impacted within 150 m of the incident, which led to several tonnes of coal fines entering the river, and there is concern that the incident could impact the Greater Blue Mountains World Heritage Area, which is less than two kilometers downriver of the incident.

The BGS Open Day - 27 June 2015

Iain Stewart gets captured in 3D!The BGS 2015 Open Day was held in Keyworth, Nottingham on Saturday 27th June. This year, not only did we have our very own staff on site demonstrating their science, we also had staff from our sister centres (British Antarctic Survey, Centre for Ecology and Hydrology, National Oceanography Centre, National Centre for Atmospheric Science, National Centre for Earth Observation and of course NERC) to help NERC celebrate their 50 year anniversary.

Series of landslides kills at least 30 in Darjeeling, India.

Sciency Thoughts | 3 July, 2015
At least 30 people have died and at least sixteen more are still missing following a series of landslides which struck the Darjeeling District of West Bengal State, India, in the first few days of July 2015. At least 25 separate landslides have occurred, several hitting homes in towns and villages and others blocking roads and railways, thereby hampering rescue efforts. The highest death toll occurred in the resort town of Mirik, where seventeen people have now been confirmed dead and over 200 are currently living in temporary accommodation due to damage to or destruction of their homes. Deaths have also been confirmed in Kalimpong, Lava, Sukhia and Gorubathan.

GeoEd: Social Communications

EGU Geolog | 3 July, 2015
We all know that social media is an excellent way in which we can communicate our research (and indeed our rants, dreams, and favourite cat pictures) to the general public, but can we also use it to communicate our research in the classroom? From kindergarten to higher education, social media can be a fantastic learning tool, which can help to open up digital windows into the world of geosciences.

Driving Through the Most Dangerous Plate Boundary in the World: A Tale of Two Subduction Zones

Geotripper | 2 July, 2015
To many people, the Sierra Nevada means granite. The Sierra Crest, with towering peaks of granite carved by glaciers. Yosemite and Hetch Hetchy valleys, with vertical walls of granitic rock. Lake Tahoe, surrounded by granite peaks. Those who visit the mountains find "granite" to be three-quarters true. A quarter of the mountain range is composed of other rocks. Some slopes are covered by the volcanic rocks mentioned in the previous post. But in the Mother Lode, that of California's legendary Gold Rush, the slopes are composed of metamorphic rocks. And the story told by the rocks is fascinating.

Wooster’s Fossils of the Week: An Upper Ordovician cave-dwelling bryozoan fauna and its exposed equivalents

Wooster Geologists | 2 July, 2015
This week's fossils were the subject of a presentation at the 2015 Larwood Symposium of the International Bryozoology Association in Thurso, Scotland, last month. Caroline Buttler, Head of Palaeontology at the National Museum Wales, Cardiff, brilliantly gave our talk describing cryptic-and-exposed trepostome bryozoans and their friends in an Upper Ordovician assemblage I found years ago in northern Kentucky. They were the subject of an earlier Fossil of the Week post, but Caroline did so much fine work with new thin sections and ideas that they deserve another shot at glory. We are now working on a paper about these bryozoans and their borings. Below you will find the abstract of the talk and a few key slides to tell the story.

Saberkittens Were Double-Fanged for 11 Months

Laelaps | 2 July, 2015
The La Brea asphalt seeps have me trapped. It seems I can't visit Los Angeles without stopping by the Ice Age treasure trove to pester the paleontologists at Project 23 about what they're finding and wander among the chocolate-colored skeletons inside the Page Museum. And in those halls, there's one exhibit that never ceases to amaze me. Lined up behind glass are Smilodon skulls with two sets of fangs.
