Paola Rivera-González MS in Geology Final Defense

On April 5, 2023, Paola Rivera-González successfully defended her Geology Master of Science degree.

Title: Climate Changes in El Salvador: Impacts of ‘La Canícula’ (“Dog Days of Summer”) on Agricultural Practices and Decision-Making in Rural Communities

Abstract: The Central American Dry Corridor (CADC), a tropical dry forest region, is characterized by distinct rainy and dry seasons that influence the local agricultural calendar and decision-making in rural communities. ‘La canícula’ is a period of decreased precipitation during the rainy season, which typically occurs in July during the corn growing season in El Salvador. The ‘canícula’ is expected to change in intensity and duration in the next decades, which would impact small-scale farmers and their livelihoods. Climate variability and uncertainty has led to crop loss, water scarcity, and food insecurity in rural communities dependent on subsistence farming. Farmers’ experiences with a changing climate led to reformed decision-making and agricultural processes (eg. agricultural calendar, seed type usage, crop rotation) to optimize their harvest and adapt to a variable climate. Studying the local perceptions and adaptation practices of farmers showed how natural hazards related to global climate change impact society, community dynamics in how farmers identify their main challenges, and revealed the ways farmers improve resilience to a changing climate.

Title: Rain-induced hazards in remote, low-resource communities: A case study of flash flooding in the Usulután Department, El Salvador

Abstract: Natural hazards like flash floods can cause devastating impacts, so it is important to better understand these events to improve mitigation and emergency preparedness of vulnerable communities. California, El Salvador is a data-poor agricultural community experiencing climate change impacts and associated hazards, including flash flood events. This study uses ArcGIS Pro to map regional flash flood susceptibility and applies the Water Evaluation and Planning system (WEAP) to model sub-daily flash flood events in a California drainage well-known for flash flooding.

Beth Bartel Receives the NAGT Outstanding Teaching Assistant Award

Beth Bartel, a geology doctoral student at the Geological and Mining Engineering and Sciences Department, receives the NAGT Outstanding Teaching Assistant Award. NAGT recognizes outstanding teaching assistants in geoscience education.

“Teaching at Tech has been a fantastic learning experience. GMES assigned me to courses I could contribute to from my particular academic and professional experience—and yet, I have learned how much more I still have to learn in these subjects, through the planning of courses, the lead instructors, grading, and the students,” Bartel says.

“Coming into my PhD, I was curious whether I would enjoy teaching a semester-long course after having only recently taught short courses and workshops,” she adds.

“I love it!

“I appreciate being able to support students, come up with creative ways to engage students, and take time to explore material together.”

GMES Professors Ranked Among the Top Scientists in 2022

Numerical indices support what every volcanologist knows: Bill Rose ranks among the top scientists in 2022. Research.com compiles and analyzes publication data, including citations and h-index of scholars worldwide. In the Earth science field, over 6,400 scientists were evaluated, and professor emeritus Bill Rose is ranked 97th in the U.S. and 179th globally.

Bill came to Michigan Tech after obtaining his Ph.D. in geology at Dartmouth College. His graduate studies included field studies of active volcanoes across Pacific Latin America. The eruption of Mt. St. Helens in 1980 brought his expertise to the forefront in the US, and the geology graduate program grew in terms of number and reputation. His entire career, save for sabbaticals, has been at Michigan Tech, where he has supervised 23 Ph.D. and 57 M.S. students. He has authored and co-authored over 200 publications, which as of this ranking, were cited in more than 16,000 other publications, yielding an h-index of 81.

Bill served as chair of the GMES department from 1990 to 1998. After returning to faculty full-time, he led the development of two international programs that greatly impacted the international reputation of the department. Every volcano observatory in the US has Ph.D. scientists on staff who are former students of Bill. If you walk into a volcano observatory around the world wearing a Michigan Tech emblem, invariably, someone will ask if you “know Bill Rose.”

GMES Student Travels with Women in Physics

Geophysics Ph.D. student Gabriel Ahrendt recently participated in an outreach activity at the Gwinn HS organized by Michigan Tech Women in Physics. On April 28th, he and the six other chapter members visited Daniel Kelpela’s junior and senior physics classes to give presentations on each member’s research and their particular concentrations in physics— including geophysics, atmospheric physics, applied physics, materials science, and astrophysics.

Gabriel presented his research on using rock magnetism for mineral exploration, structural mapping, and tectonic studies using paleomagnetism, as well as the timing of the Earth’s early inner core formation.

Gabriel Ahrendt presenting to high school students.

The 70 high schoolers received a basic rundown of the researchers’ projects, including a basic synopsis of the topic, methodology, and raison d’etre. Here, the students received some insight into applied and theoretical physics research such as magnetic geodynamo,  simulations of ice nucleation and cloud seeding, phone battery design and production of synthetic magnets, studies on the effect of airborne particulates on climate, and the search for dark energy. 

During the demonstrations, the students were able to ask more personal questions of the researchers and share their interests after finishing high school. A few showed interest in attending Michigan Tech for geology and geophysics!

After the presentations, the students walked around to 10 different demonstrations of basic physical principles ranging from concepts like static friction — where two students tried to rip apart two phonebooks connected by having their pages intercalated,  to concepts like resonance, where they made water vibrate through the audible properties of a brass bowl. Other demos included showing optical principles of diffraction through laser pointers diffracting off of CDs and DVDs, and conservation of momentum while spinning. Gabriel presented principles of rock magnetism by differentiating magnetic minerals by measuring their susceptibility and physical properties. 

Gabriel’s Ph.D. research is supported by the USA National Science Foundation and the US Geological Survey. He is advised by Dr. Aleksey Smirnov.
