Monday Geology Picture: Great Barrier Reef, Australia

Mon, 02/08/2016 - 4:11pm
For today’s “Monday Geology Picture” post I thought I’d share one shot of the Great Barrier Reef that my husband took during our vacation to Australia last year. Stay tuned for some more pictures from that trip! One of the items on my blogging to-do list is sharing some more pictures and information from our Australian adventure.

Taking responsibility for disaster risk reduction

Mon, 02/08/2016 - 3:12am
The recent Taiwan earthquake and the Samarco tailings dam failure both illustrate the critical role of individual responsibility in disaster risk reduction

60 Minutes of Real Climate Science

Sun, 02/07/2016 - 7:07pm
It’s almost impossible for the average person with no science background to get good basic info about climate change (on TV or online). So, here’s some information that you can rely on. First dispelling a popular myth, and then a lecture by Dr. Michael Mann to Physics students at the Univ. of Virginia recently. Regurgitated Climate Myth Those who find the truth extremely inconvenient to their political worldview, love to …

If Journalism is About Truth, Then Why Are Top Newspapers Knowingly Publishing This Lie

Sat, 02/06/2016 - 8:48pm
Astrology is bunk. Hopefully you know that, but it really does beg the question of why almost every Sunday paper in America will publish a load of silly lies tomorrow, and yes it does matter. Science literacy is a serious issue in America, and I know this because not ONE of the top Republican candidates for President of the United States will admit that climate change is real, much less …

Sols 1245-1247: Analyzing Murray formation bedrock

Sat, 02/06/2016 - 12:00pm
On Sol 1244, Curiosity bumped 2 meters forward to get to a nice patch of bedrock.  The focus of the weekend plan is to study typical Murray formation bedrock, do some targeting remote sensing, and then drive towards the Naukluft Plateau. The 3-sol weekend plan starts by using the DRT to clear off the dust on the target “Kudis.”  Then we’ll acquire MAHLI images of this typical Murray formation bedrock.  …

The Story of Western Science, by Susan Wise Bauer

Sat, 02/06/2016 - 7:20am
I have a great book to recommend today – a book that takes a “Great Books” approach to tracking the advance of western science through history. The book is called, straightforwardly, The Story of Western Science. Its author is Susan Wise Bauer, who writes with a confident erudition and a clear, solid style. She surveys key works in the literature that illustrate the development of scientific thought – all of …

Sol 1244: Bump, Set… Scuff!

Thu, 02/04/2016 - 12:00pm
Today’s plan is focused on bumping towards a bedrock target to set us up for contact science in the weekend plan.  As we bump forward, we’ll use the rear wheels to create one last scuff in Namib Dune, which we’ll image as we drive away. I was the GSTL today, and we had a busy morning deciding where to drive to and how to image the scuff that we’ll create.  …

The Highlands Controversy, by David Oldroyd

Thu, 02/04/2016 - 9:41am
While I’ve spent quality time in Ireland on previous trips, I’ve never been to Scotland. To me, it is terra incognita, and I am eager to explore it this summer.  It was with delight then, that I delved into David Oldroyd’s The Highlands Controversy, which at once tickled many parts of my brain: the structural geology part, the history of geology part, and the part that gets giddy with anticipation …

Science storytelling and AAAS 2016

Thu, 02/04/2016 - 8:58am
By Shane M. Hanlon Being a scientist in Washington D.C. can be exciting with many opportunities in research, policy, and communication. This month is going to be an especially amazing time to be a scientist in the nation’s capital, especially if you’re interested in science communication. The annual American Association for the Advancement of Science (AAAS) meeting is being held in D.C. on February 11th – 15th. The theme this year is “Global Science …

Landslides near Muzaffarabad from the 2005 Kashmir earthquake

The 2005 Kashmir earthquake in Pakistan triggered large numbers of landslides. Google Earth imagery illustrates their dramatic impacts

Really NBC?? Really??

Wed, 02/03/2016 - 8:57pm
Really NBC? Really?? Did you forget about the SPC Enhanced risk outlook from two days before. Did you forget about the Tornado Watch hours before, and the numerous tornado warnings minutes before?? Really?? You owe an apology to the NWS and the broadcast mets in that area who made sure there WAS a warning. Really. You do. The map below was issued by the Storm Prediction Center about 36 HOURS …

Recognize an early-career geoscientist for excellence

Wed, 02/03/2016 - 5:00pm
Now that AGU is accepting nominations for this year's awards (the deadline is March 15), I thought I'd throw out a pitch for the early career awards - and particularly the one that I'm most heavily involved in, the Science For Solutions Award.

Book Review: Diamonds, Gold, and War

Wed, 02/03/2016 - 4:47pm
Earlier this week I shared a picture of a few books on diamonds that are on my current reading list. I’ve also mentioned in a couple of previous posts that I’d like to share with you a little information about some of the geology-themed books that I’ve read recently. Today I’ll be blogging about the first book, which is titled Diamonds, Gold, and War: The British, the Boers, and the …

Study shows North Atlantic Ocean carbon storage doubled over last decade

Wed, 02/03/2016 - 1:25pm
A new study shows that the North Atlantic Ocean absorbed 50 percent more man-made carbon dioxide over the last decade, compared to the previous decade. The findings show the impact that the burning of fossil fuels have had on the world’s oceans in just 10 years.

Sol 1243: Getting ready to leave Namib Dune

Wed, 02/03/2016 - 12:00pm
The contact science activities on Sol 1242 were successful, which completed our investigation at the Namib Dune sampling location.  I love the above Navcam image, which shows just how close we were able to get MAHLI to the dump piles, followed by the really high-resolution MAHLI image!  Now it’s time to leave Namib Dune and head off in search of the next drill location. I was the GSTL today, and …

Three new landslide videos, including a debris flow from Aconcagua, an earthflow from Muothatal in Switzerland and coastal erosion in Pacifica

Sol 1242: Last analyses of the dump piles

Wed, 02/03/2016 - 2:00am
Today was the last day for science activities at Namib Dune, as we’re planning to drive away on Sol 1243.  It’s fun looking at the disturbed sand in the workspace, and realizing how much we’ve done here (is it just me, or does it look like a big sandbox full of scoops, dumps and wheel scuffs?).  While it might look like Curiosity has just been playing in the sand, we’ve …
