Brendan Harville Presents at the Michigan Space Grant Consortium Annual Conference in Kalamazoo, MI

From his first weeks in the GMES Department, Brendan Harville was interested in getting involved in research. Through a handful of well-timed events in Brendan’s first semester, he seized an opportunity to submit a research proposal with Dr. Greg Waite to the Michigan Space Grant Consortium (MSGC) undergraduate fellowship to conduct research regarding “Seismic Amplitude-based Lahar Tracking for Hazard Risk Mitigation at Fuego Volcano in Guatemala.” Brendan’s proposal was selected, leading him to plan fieldwork in Guatemala with fellow PhD student Gustavo Béjar-López. Brendan and Dr. Waite used seismic data to create a model that
can locate and track how lahars propagate down drainages from Fuego’s flanks. The work took many twists and turns (as research often does!) and resulted in an improved understanding of how the morphology of Fuego and its many drainages influence lahars and their impacts. Brendan’s work was accepted by MSGC for an oral presentation at the MSGC Annual Conference on October 21, 2023. GMES student Conor Large accompanied Brendan for his presentation over MTU’s Fall Break.

Reflecting on the entire MSGC experience, Brendan says, “My experience with undergraduate research through MSGC was invaluable. I met, connected, and collaborated with many admirable and inspiring peers and mentors for which I am truly grateful for. Special experiences like these are what invigorate and propel students like me toward future goals and aspirations. I would never have enjoyed this opportunity if I hadn’t pushed through my initial fears and feelings of self-doubt.”

GMES celebrates Brendan’s accomplishment and is proud to have submitted four new MSGC proposals this week for the Consortium’s annual call.

EPSSI Seminar: Role of Subsurface Engineering and Geology in the Energy Transition World

Mary Herrmann-Foley, MBA, returns to campus as the EPSSI Seminar guest speaker on Monday, October 23, 2023, from 4 – 5 p.m. in M&M room U113. Mary completed her Bachelor’s Degree in Geological Engineering at Michigan Tech in 1983. She continued her education at the University of Houston, earning her master’s in business administration in international finance in 1985. Currently, she serves as Manager of Central Support PetroSigns SSW application at Shell. Last fall, Mary was inducted into the Academy of Geological and Mining Engineering and Sciences. We are excited to welcome her back to campus once again!

In her talk, Role of Subsurface Engineering and Geology in the Energy Transition World, she will discuss the essential role of subsurface engineering and geology in the changing world of energy transition.

From the abstract: The world is in the midst of the first “truly global energy crisis,” the International Energy Agency (IEA) said in its World Energy Outlook in October 2022. It’s multidimensional and comes with the challenge of global warming and the need to reduce/eliminate CO2 emissions. We are all experiencing the impact of rising CO2 in the atmosphere: ocean levels rising, more intense storms, and increasing temperatures with corresponding implications on us and the environment around us. Conflicting pressures linked to continued high-energy demand, the need for energy security, and the imperative for reducing CO2 emissions are driving unprecedented renewable energy growth. This presentation will touch on the challenges related to these conflicting pressures and how existing and start-up energy companies are addressing some of these challenges through numerous renewable energy and carbon sequestration options, mainly focusing on the crucial role subsurface engineering and geology can play in this journey. Highlights of Michigan’s current situation and related business opportunities will also be discussed.

All are welcome to attend.

GMES Students Wow Houghton Elementary

We are delighted to recount the recent visit of two Geological and Mining Engineering and Sciences (GMES) students to Houghton Elementary School, where the Rock Your School event sparked geologic wonder. Jhuleyssey Sanchez Aguila, an MS student in geological engineering, and applied geophysics undergrad student Brendan Harville took center stage as they masterfully conducted a captivating presentation on volcanic hazards, capturing the imaginations of the bright minds in the third, fourth, and fifth grades.

It was an immensely gratifying experience for all involved as the students exhibited an insatiable curiosity, inspiring questions that underscored their genuine interest in the particularities of geological science. The eagerness displayed by the young learners further reinforced the value of fostering scientific curiosity at an early age. This collaborative effort between our university and the elementary school enriched the children’s educational experience. It exemplified the profound impact that dedicated mentorship and knowledge-sharing can have on the budding scientists of tomorrow. TV6 gives a nod to Michigan Tech in the concluding comments of their news segment.

A special thank you to Jhuleyssey and Brendan!

Title: Exploring Ground-Penetrating Radar Responses to Basaltic Terrain for Upcoming Lunar Expeditions

Abstract: In preparation for upcoming lunar expeditions, a comprehensive understanding of the Moon’s geophysical properties is imperative, particularly in the context of resource identification and extraction. This study focuses on the experimental characterization of electromagnetic (EM) behavior in the radio spectrum for ground-penetrating radar applications, utilizing basaltic Keweenawan stamp sand and highland lunar simulant soil test materials with varying particle grades. Under controlled laboratory conditions, we systematically analyzed and compared the differences in EM wave velocity and signal amplitude as a function of particle size and mineralogy, as represented in radargrams. Our findings demonstrate that the highland lunar simulant exhibits a significantly higher EM reflection coefficient than the stamp sand, which can be attributed to its lower conductivity arising from compositional differences. These results hold important implications for the development of remote sensing techniques and optimization of ground-penetrating radar systems for future lunar missions, ultimately enabling the efficient detection and extraction of valuable resources such as water ice on the lunar surface.

Congratulations Spring 2023 Graduates!

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.
