EARTH Magazine: EARTH: Bringing Geoscience to Bear on the Problem of Abandoned Mines

EARTH Magazine

From EARTH magazine, June 30, 2016  --  Last summer, while the abandoned Gold King Mine in Colorado was being studied for acid mine drainage, the earthen plug blew out, releasing millions of gallons of acid mine water into the Animas River, which eventually drains into the San Juan and Colorado rivers and ultimately Lake Powell. The images were startling, but this event added momentum to the national dialog on remediating abandoned mine lands. EARTH Magazine explores the role geoscience plays in this process. 

EARTH Magazine: Seeing the Seafloor in High Definition

EARTH Magazine

From EARTH Magazine, June 3, 2016  --  As the U.S. celebrates National Oceans Month in June, scientists who study the seafloor are excited because they believe that humans will end this century with a far better view of our seafloor than at any other time in human history. Geoscientists have been mapping land on Earth, and even other planets in our solar system, in high definition for years, but the picture of the ocean floor has remained blurry for the most part. But with advances in engineering, what lies beneath is starting to come into much better focus. 

EARTH Magazine: Dating of Landslides Around Oso Reveals Recurring Patterns

EARTH Magazine

From EARTH Magazine, June 21, 2016  --  In March 2014, 43 people were killed when 7.6 million cubic meters of mud and debris violently engulfed a portion of Oso, Wash., after a period of heavy rain. The region where this occurred is characterized by impermeable clay and silt deposits, sometimes measuring more than 200 meters thick, which formed 16,000 years ago when an ice sheet covered the region. These deposits and the addition of a wet, rainy climate makes the Stillaguamish River Valley ripe for more landslides. 

EARTH: Double Trouble - Volcanic Eruption Leads to Strong Earthquake Eight Months Later

EARTH Magazine

From EARTH magazine, June 15, 2016  --  A 2002 eruption of  Nyiragongo in the Democratic Republic of the Congo that killed more than 100 people also triggered an earthquake eight months later that shook the town of Kalehe in the Lake Kivu region. EARTH Magazine explores just what happened to better understand a region that is being pulled apart by plate tectonics. 

Geoscience Currents #109: U.S. Geoscience Enrollments Grow, Degrees Slide in 2015

American Geosciences Institute

From AGI  -- In Geoscience Currents #109, we take a look at the latest reported enrollments and degrees granted in U.S. Geoscience Programs.  Overall, geoscience enrollments remain robust, growing 7% for undergraduate enrollments. Graduate enrollments remained flat between 2014 and 2015.  Noticable within the reported data is the growth of wholly online geoscience degree programs, which account for more than all of the recognized enrollment growth of undergraduate majors in 2015.

EARTH Magazine: The Most Dangerous Fault in America

EARTH Magazine

From EARTH Magazine, 05/23/2016  --  When people think of dangerous faults in America, the the San Andreas probably comes to mind first. But another potentially greater threat lurks in the East Bay region of Northern California, just a stone's throw from San Francisco and the tech hub of Silicon Valley: the Hayward Fault. In the June issue, EARTH Magazine guest author Steven Newton lays out just what is at risk, and what to expect when an earthquake strikes on what may be the most dangerous fault in America.

EARTH Magazine: Did the Medieval Warm Period Welcome Vikings to Greenland?

EARTH Magazine

From EARTH Magazine, May 16, 2016  --  What is known: Vikings sailed to Greenland. They homesteaded there for a few hundred years, and likely experienced multiple famines. Many died. Some returned to European shores. And all of this happened during a time in Europe known to geoscientists as the Medieval Warm Period. The warmer, milder conditions that defined this time eventually ended too. 

EARTH Magazine: Growth Rings in Rocks Reveal Past Climate

EARTH Magazine

From EARTH Magazine, May 5, 2016  --  For years, scientists have used mineral, sediment and ice layers, deposited intermittently throughout geologic time, to track the global climate record. These can come from caves, lakes, the oceans and ice sheets. But over the course of the last decade a new method has been developed that presents an opportunity for geoscientists to assess global climate history in almost any arid landscape.
