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.

Hunting for Plastics – Making Connections Through Lower Division Courses

Division of Science and Math Work Group: Julie Masura and Megan Schwartz (co-chairs) Bonnie Becker, Erica Cline, Jeremy Davis, Jutta Heller, Meg Henderson, Erik McDonald, Peter Selkin, Haley Skipper, and Cynthia Stanich

In 2014, twelve faculty from the Division of Science and Math joined together to develop high standards for lower division students taking Natural World courses as a part of the CORE curriculum. Action among this faculty stems from the reconciliation of the vision for the CORE experience from the Vice Chancellor of Academic Affairs and the Office of Undergraduate Education. Four faculty attended a conference on lower division biological education which they shared with the Science and Math faculty (see www.pulsecommunity.org). The result of that conference led to reformatting our Lower Division undergraduate courses through implementation of high impact educational practices as identified by the Association of American Colleges and Universities (see www.aacu.org/leap/hips).

The workgroup created a curriculum for our freshmen class to be followed by faculty teaching in the CORE, and committed to not only providing faculty development, but also perform an assessment measuring science attitudes and skills of students taking these classes. Each student taking a Natural World course will be exposed to data collection, field and laboratory experiences, field and laboratory reports, academic research, data analysis, and place-based activities. Our intention is a pledge to ensuring every student experience the “science” in interdisciplinary arts and sciences.

During the summer of 2015, Erik McDonald restructured his Natural World course using the framework developed by Julie Masura’s CORE course ‘Oceans Full of Trash.’ One of the activities/experiences for his students was to collect and categorize microplastics, macroplastics, and megaplastics at Thea’s Beach on the Thea Foss Waterway and Owen’s Beach at Point Defiance Park (see figure). For another part of the lesson, the students graphed their data (including uncertainty) in Excel and wrote a report on their experience. They will continue to explore the impacts of plastics pollution on ecosystems, while understanding their social responsibility of educating others and modifying behaviors to lessen the effect on their environment.

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“.

Faculty Spotlight – Maureen Kennedy

Kennedy-Maureen UWT Assistant Professor

Maureen Kennedy is a new assistant professor for UW Tacoma Sciences and Mathematics (SAM).

For her graduate work, Maureen Kennedy developed a simulation model of branch morphogenesis for old-growth conifers. She used multi-criteria optimization to discover branch morphologies that represented alternative optimal solutions to the problem of longevity under growth constraints. She has since applied multi-criteria optimization to the problem of fuel and fire management under multiple ecological and social priorities. Maureen continues to conduct quantitative research in model uncertainty assessment, in understanding spatio-temporal patterns in fire history data, in employing spatially explicit analysis to evaluate fuel treatment efficacy during wildfire, and in estimating non-linear growth and yield models for sustainable forest management.

Maureen is excited to continue her research and teaching at UW Tacoma. When not teaching or conducting research Maureen spends much of her free time walking and jogging with her dog in their NW Seattle neighborhood. She and her partner can often be found riding their bicycles around Seattle, or spending their Saturdays at restoration sites throughout the Mountains to Sound Greenway, volunteering in trail work, tree planting, or invasive species removal. They also enjoy the ample opportunities to hike or kayak on local trails and waterways.
