Happy Holidays: A Note from the Chair

Dr. Aleksey Smirnov, Professor and Chair, Department of Geological and Mining Engineering and Sciences

Dear Alumni and Friends!

I hope that this newsletter finds all of you and your families healthy and safe. Winter is in full swing in Houghton County, with over 30″ of snow this season so far. The Tech Trails are groomed, the broomball fields are set, our students have completed final exams and many are celebrating their recent graduation. As the holidays approach, I am happy to share some exciting developments that happened at the Department of Geological and Mining Engineering and Sciences since we sent you our previous newsletter in early June.

Before all, I am thrilled to report that our recently-reinstated Bachelor of Science in Mining Engineering program has been accredited by the Accreditation Board for Engineering and Technology (ABET). The meticulous accreditation process ensures that the program meets the strictest professional standards and provides the students with a solid educational foundation and posits them for successful and impactful careers. You can read more about it here.

Our faculty, staff, and students continued their diligent and productive work to move our department forward. 

Due to the previous year’s cancellations, this summer we offered two sections of our Field Geology and Field Geophysics courses each. Everyone was happy to get back in the field for experiential learning. And to add to the excitement, our Field Geophysics students were the first cohort to take the advantage of cancellation of the laboratory fee, thanks to the Carl G. Schwenk Field Geophysics Lab Endowment.

Our faculty, alumni, and students have been recognized for their contributions and hard work. Most importantly, we celebrated two of our colleagues being named inaugural faculty fellows. Dr. Snehamoy Chatterjee, Associate Professor, was appointed the Witte Family Endowed Faculty Fellow in Mining Engineering; and Jeremy Shannon, Principal Lecturer, was named the Carl G. Schwenk Faculty Fellow in Applied Geophysics. We are extremely grateful to Carl Schwenk and the Witte family for their generosity, which will have a tremendous and long-lasting impact on the academic and professional successes of our students and faculty. 

This fall, we congratulate Angela Hammond (BS ’00, MS ’02; Geological Engineering) who has been inducted into the Presidential Council of Alumnae.

Our students continue to be successful in their classes, participating in research, and presenting their work worldwide. These efforts have brought them much recognition. Most notably, our student chapter of the American Institute of Professional Geologists (AIPG) has been named the 2021 Student Chapter of the Year for the second year in a row! We also are very proud of Emily Street, a mining engineering senior, who won a prestigious nationwide 2021 Copper Club Lord Bagri Scholarship.

Last but not the least, our heartfelt congratulations go to our Summer and Fall 2021 graduates.

On behalf of our students, faculty, and staff, I would like to express my deepest appreciation to all of you who have provided support to our department! Your support is more important for us than ever during these challenging times. As we head toward 2022, we are aware of the hurdles we face, and the opportunities ahead. We look forward to your continued engagement with GMES as we recommit to our mission and goals.

As always, I will be happy to hear from you at any time by email (asmirnov@mtu.edu), phone (906.487.2365), or in-person (Dow 631).

Wishing you a very happy holiday season and a peaceful and prosperous new year!

Summer Field Geophysics Becomes More Affordable: Thanks to Carl Schwenk!

Jeremy Shannon and GMES students gather for a celebration picnic after final presentations.

Thanks to the generosity of alumnus Carl Schwenk our unique summer course in Field Geophysics has now become more affordable for our students. Starting this past summer, the Carl G. Schwenk Field Geophysics Lab Endowment began to cover all course expenses not tuition related, such as annual costs for travel, field supplies, periodic equipment maintenance, instrument rental, and equipment replacement. This support made it possible to reimburse the hefty $450 laboratory fee in full to each student who took the course this year. And no laboratory fee will be required for Field Geophysics in the future, starting in summer 2022.

“We all here in the GMES department are very grateful to Carl, who has made significant professional contributions to field geophysics and mineral exploration throughout his career,” says Aleksey Smirnov, chair of the Department of Geological and Mining Engineering and Sciences, “As an alum, he remains closely and actively involved with our department, providing tremendous support to our students over the years.” 

Schwenk earned a BS in both Geological and Geophysical Engineering from Michigan Tech in 1962 and 1965, respectively. He worked as a Field Geophysicist with Kennecott Copper Corporation and was instrumental in the discovery of the Flambeau copper-gold Mine in Wisconsin. Later, he worked with the large iron company Vale do Rio Doce exploring for base metals in Brazil. After his return to the USA, he was hired as Great Lakes District Manager for Noranda Exploration and led a successful State Supreme Court challenge to Wisconsin’s Geologic Disclosure Law. 

Principal Lecturer Jeremy Shannon, Carl G. Schwenk Endowed Faculty Fellow in Applied Geophysics, teaches the Field Geophysics courses at Michigan Tech. “This is a great gift for our students and I can’t wait to share Carl’s story of his contribution each summer,” he says. “The cost of equipment and resources used in the class is significant, but inevitably spread out over time scales that are beyond any student’s undergraduate career. Thus students are often left wondering what their lab fees are really being used for. Carl’s gift takes a dent out of the ever-increasing cost of a college education while ensuring that students will continue to have access to modern geophysical instrumentation.”  

Olivia Salvagio, an applied geophysics senior, adds: “Field Geophysics was where I learned that I wanted to continue my education on near surface geophysics in graduate school! I was so intrigued by each of the methods and the equipment that we used and the broad applications that they have to Earth science.”

Emilie Pray, a geology senior, had this to say: “Field Geophysics was the class that fully cemented the concepts learned in the classroom into real-world applications. Along with practice in technical writing skills and group work in the field, I believe this class has prepared me well for my future career.”


Jeremy Shannon Named Carl G. Schwenk Endowed Faculty Fellow in Applied Geophysics

Michigan Tech Principal Lecturer Jeremy Shannon is the Carl G. Schwenk Endowed Faculty Fellow in Applied Geophysics

Jeremy Shannon is the Carl G. Schwenk Endowed Faculty Fellow in Applied Geophysics, named in July 2021. 

“For more than a decade Dr. Jeremy Shannon has been a key faculty in field geophysics at Michigan Tech,” said Aleksey Smirnov, chair of the Department of Geological and Mining Engineering and Sciences. 

“Dr. Shannon provides vital contributions to GMES instruction and advising, especially through the summer Field Geophysics course and specialized courses in the application of near-surface geophysics methods,” added Janet Callahan, Dean of the College of Engineering. 

The endowment was established by Carl G. Schwenk, who obtained a BS in both Geological and Geophysical Engineering from Michigan Tech in 1962 and 1965, respectively. He worked as a Field Geophysicist with Kennecott Copper Corporation and was instrumental in the discovery of the Flambeau copper-gold Mine in Wisconsin. Later, he worked with the  large iron company Vale do Rio Doce exploring for base metals in Brazil. After his return to the US he was hired as Great Lakes District Manager for Noranda Exploration where he led a successful State Supreme Court challenge to Wisconsin’s Geologic Disclosure Law. 

“Carl lives in Colorado and remains closely involved with our department, providing tremendous support to our students,” said Smirnov.

Shannon is also a Michigan Tech alumnus, and took the Field Geophysics class as an undergraduate in the summer of 1992. He was honored to take over the class in 2007 and has continued and built upon the legacy of applied geophysics education at GMES created by professors Lloyal Bacon, Jimmy Diehl, and Charles Young to deliver a unique field experience for students.

“I am humbled to receive this appointment and am extremely grateful to Mr. Schwenk and others who have made this possible,” said Shannon. “I look forward to using this gift to improve and advance educational opportunities in geophysics at Michigan Tech.”

“Shannon’s contribution to the department of Geological and Mining Engineering and Sciences perfectly aligns with the purpose of the fellowship, which is to provide leadership in mentoring and teaching students at Michigan Tech in the practical use of geophysics for characterization and discovery of subsurface resources,” added Callahan.

In addition to instruction in the field of applied geophysics, which includes specialized courses in the application of near-surface geophysics methods, Shannon serves as the academic advisor for undergraduate students majoring in Geology and Applied Geophysics.

Shannon generously lends his expertise to students working on senior design projects, as well as graduate students whose research involves field work, notes Smirnov. “Dr. Shannon helps students develop both practical knowledge and intuition. As a result, they are able to find their own best academic and professional pathways, leading to impactful and rewarding careers.” 

In recognition of his contributions to teaching, Shannon was also recently honored in the Michigan Tech Deans’ Teaching Showcase


Q&A with SATAVIA: Climate and Contrails

Contrails are the biggest contributor to aviation’s climate impact. The company SATAVIA works on data analysis software to help airlines avoid long-lasting contrail formation.

Dr. Adam Durant (MS Geology ’06, PhD ’07) discussed how modifying flight plans lessen long-lasting contrails and reduce climate impacts–so-called green aviation. Physics professor Raymond Shaw and Professor Emeritus Bill Rose, who advised Adam in his graduate studies here, host the discussion.

It’s not rocket science. It’s harder — or at least harder to predict. Clouds are often referred to as the wildcard of climate modeling, and while some basic physics have become much clearer using tools like the cloud chamber at Michigan Technological University, atmospheric science remains a fascinating and complex space.

Shaw, distinguished professor of physics and director of Michigan Tech’s atmospheric sciences doctoral program, studies ice crystal formations in clouds. When Durant worked with him as a graduate geoscience student, the team studied how volcanic ash and frigid water interact in the atmosphere. For Durant, experimenting with specks of dust and drops of supercooled water coalesced into an ongoing interest in the interaction’s effects on airplanes — and the industry’s climate bill. Drawing on his interdisciplinary background, Durant started the company SATAVIA in 2013.

In their Q&A, Shaw (RS) and Durant (AD) explain how rerouting airplanes to minimize contrails can have the biggest impact with the smallest changes.

Adam Durant, CEO SATAVIA
Research Interests:
– Green aviation
– Ice crystal morphology and cloud formation
– Volcanic ash plumes
– Sustainable business

Q: Why focus on contrails to curb climate change impacts?

AD: It’s not just direct engine emissions that matter in terms of aviation’s climate impacts. Non-carbon dioxide sources — like the climate forcing from contrails — make up almost two-thirds of the industry’s impact, which is a surprisingly big number. In fact, it equates to 2% of all human-caused climate change.

RS: Contrails are pretty and localized, so it’s understandable that few people would guess they’re of consequence. And it’s relatively rare flights that make these long-lasting contrails, which are heavily weighted in terms of their climate impact.

AD: Yes, of about 500 flights, only one or two make these kinds of contrails.

Q: How does SATAVIA’s software help predict contrail formation?

AD: We are a data analytics company, building software that uses cutting-edge atmosphere and climate science. We use a commercial cloud structure to create a digital twin of the Earth’s atmosphere from surface to space, quantifying many key meteorological parameters like temperature, humidity, cloud cover and other factors that affect flight operations. We aggregate that information and apply it to different use cases, including contrail formation and other applications such as contaminant exposure and corrosion factors. Predicting contrail formation and persistence in the atmosphere is complex, so it becomes a big data problem – unless you’ve got a high-performance atmospheric digital twin, you won’t be able to crunch through the data properly. Right now, we’re working with a major Middle East airline through a collaboration with Aviation X Lab, a Dubai-based aviation incubator. They want to be proactive about assessing their impact, and they’re helping us validate our models. The next challenge is software integration, so we can help airlines optimize flight paths for contrail prevention while minimizing fuel burn.

Q: How can industry, universities and government groups work together?

RS: It’s important to acknowledge that while Michigan Tech doesn’t have direct collaborations with SATAVIA, it was a former student who started the company and a new graduate, Subin Thomas, starts there soon as a key player on their science team. Academia can play a role by training people in the fundamental science so they can carry on innovation within the private sector. We also work with agencies, like our partners at the National Center for Atmospheric Science (NCAR) and U.S. Department of Energy (DOE). For example, a current graduate student, Elise Rosky, is at this moment at NCAR flying a holographic instrument through clouds to investigate how ice forms and grows. Who knows where that fundamental research will lead, and even how it might tie into the science of contrails?

Raymond Shaw
Research Interests:
– Atmospheric Physics
– Cloud Physics
– Nucleation
– Turbulence
– Digital Holography

AD: We all want to solve real world problems. There’s a lot more to solving problems than throwing science at it. If it doesn’t cost money or make money, it’s hard to get business to care. As the cost of carbon rises, there is going to be more and more incentive for airlines to fly smarter and greener. With our model, we not only assess a flight plan and help make changes that actually lower aviation’s climate impact, but we also estimate what a company can save in associated carbon credits and carbon offsets.

Q: How did your Michigan Tech research help make these kinds of collaborations possible?

AD: This brings me back to doing my PhD on volcanic ash with Bill Rose, who blended a lot of disciplines. I felt like an atmospheric scientist but my degree was geoscience. I moved on to a climate research group next — mostly climate modelers and remote sensing experts — and that experience also brought me closer to policy.

RS: Sometimes, Adam, we jokingly call students like you a gluon [bad physics joke] — “Well, Bill does this and Raymond does that, so we need a go-between.” To Bill’s credit, he was always roving and looking for people who could help him solve the problems he was working on. So, Adam asked in his research: What happens when we put ash in a supercooled droplet? It was a logical next step to ask what happens when an airplane flies into an ash plume.

Q: What inspires you in your work?

AD: I want to take tangible action on climate change — that’s what my mission has become. We’ve been thinking about our vision as a company and it always comes back to solving climate change.

RS: We say all the time that we do basic science to help society. Examples like Adam’s company make that true. In some ways, it’s easier to stay in academia, but moving into the private sector means there is so much more potential for influence. Much of research is curiosity-driven and with a genuine interest in solving fundamental problems, with the hope that eventually the solutions will make a difference. But no one would fund us to solve puzzles every day; we hope that when we train students that our fundamental work will be connected to the private sector and help make the world a better place.

Q: What are challenges that remain ahead?

AD: Raymond, here is what we are always asked: Do we know enough about the science of contrail formation and whether we can predict it?

RS: Well, the basic physics is there. The part that is complicated, which falls under current research, is how persistent will a contrail be — will it be ice or water, and what’s the crystal shape? The good news is that the basics are clear.

AD: I agree that the fundamental science is sound, and that the challenge facing us now is scaling and creating contrail forecasts at flight altitudes so that aviation operators can avoid making them. And policy and regulation — that is what will influence how big organizations deal with this problem.

RS: That’s the surprising part. Thinking from the company spreadsheet point of view, in the right economy, SATAVIA’s approach can actually save money.

AD: Yes, many companies already pay to offset their carbon emissions. Changing flight plans would make a bigger difference and save them more money. What we need to work on most from a technical perspective is software integration, and that’s going to take time and close partnerships with more airlines.

Q: The pandemic changed travel. How has this impacted your work?

AD: Before COVID, much of our work focused on how atmospheric and climatic factors can damage aircraft engines and airframes, and responding to that with smarter condition monitoring and predictive maintenance. 

But as the pandemic began and continued, we pivoted to focus more on aviation’s impact on climate. We just happened to be at the right place at the right time with our ice crystals research. People care about green aviation now, to the extent that it will influence their choice of airline, though some consumers will always be driven by the cheapest prices. In the near term, it’s likely to be business travelers who care most about the green credentials of a flight.

RS: Even before the pandemic, I was starting to notice an uptick in the number of colleagues who would say, “I’m not going to go to that meeting because I’m trying really hard to minimize the aviation part of my carbon footprint.” Or saying, “I can’t go on that airline, I’m going to choose this other airline because they’re doing more to solve this problem.” And I do think the pandemic has made more of us aware of what can and can’t be done. The nice thing is that we can have a global aviation industry and mitigate the impact to some extent. As you think about returning to air travel, why not expect more from the airline you’re flying with? Because there are actions they can take. Contrails are something most people would never think about, but SATAVIA’s work shows that it’s possible to do something about their climate impacts.
