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.

Six GMES Students Receive Michigan Space Grant Consortium (MSGC) Awards

The Department of Geological and Mining Engineering and Sciences applauds these GMES students and their advisors for receiving the  2022 MSGC Awards:


Brendan Harville, applied geophysics junior advised by Dr. Greg Waite
Title: Seismic Amplitude based Lahar Tracking for Real-Time Hazard Assessment
Abstract: Lahars are strong debris flows or mudflows caused by volcanic activity and also non-volcanic activity in the form of heavy rainfall. They can cause extensive damage to the surrounding environment as well as local communities and infrastructure. The goal of this project is to create a fully automated lahar tracking tool for hazard risk mitigation. Lahars transmit a long-lasting, high frequency tremor signal that is observable in waveform data from seismic stations (Kumagai et al. 2009). This research project plans to use an established network of seismic stations on the slopes of Volcán de Fuego, the resulting tremor signals, and the modified technique presented by Kumagai et al. (2009) to track the origins of individual lahars in real-time.

Espree Essig, geology Ph.D. student advised by Dr. Chad Deering
Title: Analyzing the effects of heavy metals on vegetation hyperspectral reflectance properties in the Mid-Continent Rift, USA
Abstract: In a society focused on global sustainability, metals including copper, nickel and cobalt have become fundamental. Despite increasing demand, deposit discoveries have plummeted owing largely to dwindling ‘low-hanging fruit’ that are near-surface. With this challenge, exploration for buried and vegetation-covered mineralization has become more relevant. However, short of direct geological observations, a proxy correlating mineralization with surficial patterns is necessary. The aim of this study is to analyze the effects of heavy metal enrichment on the hyperspectral reflectance properties of vegetation near polymetallic (Cu- Ni-Co- PGE) mineralization in the Duluth Complex, northeastern Minnesota. This natural laboratory is regionally representative of the mineralization perspective across the Lake Superior region, where vegetation, wetlands and glacial till have impacted exploration efforts and success. This pilot-study investigation will resolve the feasibility of vegetation-based hyperspectral methods to detect poorly exposed deposits in the Lake Superior region.

Caleb Kaminski, geophysics MS student advised by Dr. Aleksey Smirnov
Title: Investigation of Ground-Penetrating Radar Interactions with Basaltic Substrate for Future Lunar Missions
Abstract: Ground-penetrating radar (GPR) is a suitable tool for interplanetary rover exploration on the Moon. Anticipated future lunar missions sponsored by governmental and private organizations alike are making headway toward a breakthrough in planetary science. Understanding the geological and geophysical properties of the lunar regolith is paramount for the beginnings of permanent structures on the lunar surface. The Moon’s surface is primarily composed of basalt, a common[AS1] volcanic rock found here on Earth. My proposed research will focus on the effect of basaltic grain size on dielectric permittivity [AS2] and electromagnetic (EM) signal velocity, using 500 MHz and 1000 MHz GPR antennas. My hypothesis is that changes in the grain size of basalt from silt to small boulders will affect the EM properties of the material. Gaining a further understanding of the interactions between basalt and EM waves will benefit future engineering and mining efforts that involve the lunar regolith.

Katherine Langfield, geology MS student advised by Dr. James DeGraff
Title: Structural Characteristics of the Keweenaw and Hancock Faults in the Midcontinent Rift System and Possible Relationship to the Grenville Mountain Belt
Abstract: Since the mapping of the Keweenaw Fault in the 1950s, significant advances in mapping technology and knowledge about fault systems have been made. This project will remap the hanging wall and footwall of the fault using advanced geospatial technology to reexamine the kinematics of the Keweenaw Fault in the Laurium and Hancock Quadrangles, Michigan.

Paola Rivera Gonzalez, geology Ph.D. student advised by Dr. Kari Henquinet
Title: Impacts of La Canícula (“Dog Days of Summer”) on agriculture and food security in Salvadoran communities in the Central American Dry Corridor
Abstract: A rising population, demand for natural resources, and a changing climate are exacerbating vulnerabilities globally and elevating the priority to mitigate risks. The impacts of these changes on agriculture in rural communities jeopardize regional food security and water accessibility. In the Central American Dry Corridor, La Canícula or the “Dog Days of Summer”—a short-duration dry period during a six-month-long rainy season—is expected to lengthen and worsen in the next decades (Anderson et al., 2019), bringing more frequent drought to countries like El Salvador. This study examines the changing canícula and its effects on rural, eastern El Salvador using ethnographic methods and physical measurements—satellite-based data of precipitation, soil moisture, and temperature—to correlate geophysical changes to farmers’ experiences, adaptation practices, and decision-making. Integrating local knowledge and hydrometeorological conditions highlights the most affected areas in agricultural communities, documents existing adaptive strategies, and may inform future adaptive planning.

Emily Gochis, geology Ph.D. ‘22, advised by Dr. John S. Gierke
Submitted through the Copper Country Intermediate School District
Title: Lift and Launch the Western U.P.: SOLID Start (Science, Oral Language, and Literacy Development from the Start of School) for First and Second Grades
Abstract: Early elementary students in the Western Upper Peninsula (WUP) have limited access to STEAM learning experiences. The WUP comprises largely remote, rural communities and is home to two Sovereign Tribal entities. WUP communities have historically lacked equitable educational resources because of isolation and poverty. Lift and Launch the Western U.P will increase student engagement in STEAM by coordinating a Pre-college Education program that includes multi-district adoption of the NGSS-aligned curriculum, SOLID Start (Science, Oral Language, and Literacy Development from the Start of School). Additionally, an educational Teacher Training program will integrate place-based and career development activities into the curriculum highlighting unique attributes of the WUP. The new professional learning program would be ongoing, including summer field experiences and school year sessions, designed to increase educators’ pedagogical content knowledge. The innovative and collaborative approach would embed regionally significant examples and community partnerships into the SOLID Start curriculum.

Dean’s Award for Outstanding Scholarship Awarded to Emmeline Wolowiec

Emmeline Wolowiec Emmeline, pictured with Turrialba Volcano in Costa Rica, thinks that her travel to Costa Rica and Switzerland for research has been a highlight of her time at Michigan Tech.

Emmeline Wolowiec, MS geology student, is recognized for her academic accomplishments, receiving the Dean’s Award for Outstanding Scholarship in the Geological and Mining Engineering and Sciences Department. A certificate of recognition for this award will be presented to Emmeline at the Graduate Research Colloquium Banquet held this spring. 

Emmeline, advised by  Dr. Chad Deering, is working to look at the generation of high silica magmas in Costa Rica. They’re looking at the connection between plutonic and volcanic rocks to see what that can tell about where in the crust the volcanic rocks formed in relation to the plutonic rocks and what the possible magma chamber structure looked like. Hopefully, this will give insight into how the volcanic rocks formed, whether through fractional crystallization, magma mixing, or other processes.
