SAM Assistant Professor Dan Shugar Published Article in Nature Geoscience

Congratulations to SIAS Sciences and Mathematics Assistant Professor, Dan Shugar for his recent publication on his research “River piracy and drainage basin reorganization led by climate-driven glacier retreat” in Nature Geoscience!

“So far, a lot of the scientific work surrounding glaciers and climate change has been focused on sea-level rise,” Shugar said. “Our study shows there may be other underappreciated, unanticipated effects of glacial retreat.”

Senior Lecturer, Linda Dawson, Publishes Book: The Politics and Perils of Space Exploration

Congratulations to UW Tacoma Senior Lecturer, Linda Dawson for the upcoming release of her new book “The Politics and Perils of Space Exploration” to be released at the end of the month by Springer.

The book is written by a graduate from NASA Langley Research Center, this book offers a complete overview of all of NASA’s next steps in space, including how future space exploration is to be funded and how space tourism is to be regulated.  Dawson’s book summarized future space exploration plans in development both in the US an abroad, including the increased shift to space privatization as changes in NASA’s mission bring it into partnership with commercial space companies.  The book considered the US political climate regarding its tolerance for risk in space travel and whether the US will continue to invest in the space arena, as the SpaceShip Two crash illustrates why mistakes become deadly.

In order to tell this story, it is important to understand the politics of space as well as the dangers, why it is so difficult to explore and utilize the resources of space.  Some past and reent triumphs and failures will be discussed, pointing the way to a successful space policy that includes taking risks but also learning to to mitigate them.

UW Tacoma Faculty Member Dan Shugar Along With Colleagues Published a Paper in Science that Describes the Landslides Caused by the 2015 Nepal Earthquake

On April 25, 2015, a magnitude 7.8 earthquake struck Nepal, eventually killing ~9,000 people and severely damaged a 550 x 200 km region in Nepal and neighbouring countries. A new study – published in Science – by IAS/SAM Assistant Professor Dan Shugar and colleagues describes the landslides that were caused by the earthquake and aftershocks, and evaluates their distribution in terms of geomorphic, tectonic and lithologic controls.  The day after the earthquake, a volunteer group of satellite analysts from a dozen countries was assembled by University of Arizona glacier hazards researcher Jeffrey Kargel, and coordinated by NASA. Shugar led a smaller group of volunteers in analysis of landslides and other induced geohazards in the Annapurna region of the Himalaya. In the end, the larger group mapped >4,300 landslides and found that their distribution was asymmetric about the epicenters of the main shock and largest aftershock(s). By comparing the landslides’ distribution with InSAR-generated ground displacement fields, the group noticed that the highest areal densities of landslides are developed on the downdropped northern tectonic block, which is likely explained by momentary reduction of the normal stress along planes of weakness during downward acceleration. Such a pattern has never before been observed for a large earthquake. The total number of landslides was also surprising, since far more landslides were expected for an earthquake of this magnitude. The paper was published in Science Express on Dec 16, and will appear in print in January 2016.

Dr. Jim Gawel was quoted by the News Tribune on November 7, 2015.  The article is titled “Three decades after the Asarco smelter shutdown, its toxic legacy surprises Tacoma newcomers” and was written by Derrick Nunnally.

The article mentions a paper by Dr. Gawel from 2013 and states

“An analysis published in an academic journal in 2013, however, found that the same pollutants have hung around the area’s freshwater basins in worrisome amounts. Sediment samples from 26 lakes within 20 miles of the smelter’s smokestack found “significantly elevated” amounts of arsenic and lead in 10 of the 12 lakes downwind of the smelter, but only in a few of the upwind lakes.”

Dr. Erica Cline’s 2012 Published Work Referenced by NPR

Salmon Pic

National Public Radio (NRP) published an article on 10/28/2015, “That Salmon On The Menu Might Be a Fraud – Especially In Winter“.  This article discusses a study that was performed December 2013 – March 2014 that concluded “Results showed that 43 percent of salmon samples tested were mislabeled, and that far more of that mislabeling is occurring in restaurants than in large supermarkets.”

The NPR article referenced UW Tacoma’s Sciences and Mathematics faculty Dr. Erica Cline’s 2012 published work “Marketplace substitution of Atlantic salmon for Pacific salmon in Washington State detected by DNA barcoding“.
