John Gierke stands with water behind him, on the shore of Portage Canal.
Water was John Gierke’s first love growing up. Now he is Professor and Chair of the Department of Geological and Mining Engineering and Sciences at Michigan Tech, specializing in hydrogeology. Here he stands at the shore of Portage Canal, on campus.

A self-professed “Yooper graduate of the school of hard rocks,” John Gierke chairs the Department of Geological and Mining Engineering and Sciences (GMES) at Michigan Technological University. He’s also an alumnus, earning a BS and MS in Civil Engineering, and a PhD in Environmental Engineering, all at Michigan Tech.

Q: How do the rocks connect us?

A: The geology of the Keweenaw and Western Upper Peninsula is quite unique and different than the Eastern Upper Peninsula and Lower Peninsula. The geology of the Keweenaw is more exposed and accessible. The experience of spending time in the Copper Country is enhanced if you understand more about the forces of nature that formed this beautiful place. While geologists are knowledgeable in identifying rocks, their truest natures are also wrapped in a yearning to be outdoors, exceptional observation skills, and insatiable curiosity to understand Earth processes. The processes that led to the geological formations that lie beneath us–and shaped our landscapes–are what dictated many of the natural resources that are found where each of us live.

Q: When did you first get into engineering? What sparked your interest?

A: I began studying engineering at Lake Superior State College (then, now University) in the fall of 1980, in my hometown of Sault Ste. Marie. In those days their engineering program was called: General Engineering Transfer, which was structured well to transfer from the old “Soo Tech” to “Houghton Tech,” terms that some old timers still used back then, nostalgically. I transferred to Michigan Tech for the fall of 1982 to study civil engineering with an emphasis in environmental engineering, which was aligned with my love of water (having grown up on the St. Mary’s River).

Despite my love of lakes, streams, and rivers, my technical interests evolved into an understanding of how groundwater moves in geological formations. I used my environmental engineering background to develop treatment systems to clean up polluted soils and aquifers. That became my area of research for the graduate degrees that followed, and the basis for my faculty position and career at Michigan Tech, in the Department of Geological and Mining Engineering and Sciences (those sciences are Geology and Geophysics). My area of specialty now is Hydrogeology.

Q: Can you tell us more about your growing up? Any hobbies?

A: Growing up I fished weekly, sometimes daily, on the St. Mary’s River throughout the year. Sault Ste. Marie is bordered by the St. Mary’s River on the north and east. In the spring-summer-fall, I fished from shore or a canoe or small boat. In the winter, I speared fish from a shack just a few minutes from my home or traveled to fish through the ice in some of the bays. I was a fervent bird hunter (grouse and woodcock) in the lowlands of the EUP, waterfowl in the abundant wetlands, and bear and deer (unsuccessfully until later in life). I now live on a blueberry farm that is open to the public in August for U-Pick. I used my technical expertise to design, install, and operate a drip irrigation system that draws water from the underlying Jacobsville Sandstone aquifer.

Michigan Tech student team advances in National Mine Design Competition

The very first Michigan Tech team advanced to Phase 2 in the Society for Mining, Metallurgy and Exploration (SME) / National Stone, Sand, and Gravel Association (NSSGA) Student Design Competition, at the 2020 SME Conference. Michigan Tech was among the top six in the nation to advance.

The annual competition is a grueling two-phase, team-based, problem-solving activity involving a technical design and an oral presentation. The problem highlights the challenges and opportunities associated with operating a sand and gravel quarry, developing an overall design plan, and optimizing the operating methods and economics. Students work on the problem from the perspective of an engineering consulting team, responsible for the development of the pit and mineral processing plant configuration.

The interdisciplinary Michigan Tech team included mining engineering majors Ben Neely, Shawn vanDoorn, and Garrett Singer; geological engineering senior Ian Gannon; and chemical engineering senior (mineral processing minor) Erin Bowers.

Nathan Manser, GMES faculty member and Michigan Tech ’01 mining engineering alumnus, is mentoring them exceptionally well,” said John Gierke, past chair of the Department of Geological and Mining Engineering and Sciences.

The competition’s Phase 1 design took place during fall semester on campus over a 21-day period. The top six teams were selected based on their design reports.

The team went on to compete in Phoenix, culminating with an oral presentation. They were asked to modify their design in response to a change provided at the start of the competition. They were also interviewed by industry practitioners during the course of their work.

Although our team did not make it to the podium, the judges complimented the novelty of their design and the diversity of their team.

Seismic Reflections: Siting the Gordie Howe Bridge

The Gordie Howe International Bridge connecting Windsor, Ontario, and Detroit, Michigan is currently under construction and expected to be complete in 2024 at a cost of $5.7 billion.  The bridge is named in recognition of the legendary hockey player, a Canadian who led the Detroit Red Wings to four Stanley Cup victories.

The construction of any large infrastructure project requires a strong foundation, especially one with the longest main span of any cable-stayed bridge in North America—namely, the Gordie Howe International Bridge over the Detroit River. More than a decade before ground was broken, careful siting of the bridge began to take place. By 2006 the list of possible crossings had been narrowed down to just two options.

Historical records from the early 1900s indicated that solution mining for salt had taken place on both sides of the river close to where the bridge was to be built. On the Michigan side, collapsed salt cavities caused sink holes located on nearby Grosse Isle. It was imperative that any salt cavities in the bridge construction area be found and avoided.

Seismologists Roger Turpening and Carol Asiala at Michigan Technological University

Seismologists Roger Turpening and Carol Asiala at Michigan Technological University were tasked by American and Canadian bridge contractors to select the best seismic method for searching for any cavities in the two proposed crossings—referred to at the time as “Crossing B” and “Crossing C”—and to interpret all resulting seismic images.

“Given the task to image a small target deep in the Earth, a seismologist will quickly ask two important questions: How small is ‘small?’ and How deep is ‘deep’? That’s because these two parameters conflict in seismic imaging,“ Turpening says.

“Seismic waves—vibrations of the Earth—are attenuated severely as they propagate through the Earth,” he explains. “Imaging small targets requires the use of high-frequency, seismic energy. When seismic sources and receivers are confined to the Earth’s surface, which is the usual case, waves must propagate downward through the Earth, reflect off of the target, and return to the surface. Soil, sand, and gravel in the surface layer overwhelmingly cause the greatest harm to image resolution, and the ray paths must pass through this zone twice.”

Turpening was one of the early developers of a technique called vertical seismic profiling, or VSP. “Seismic receivers are placed inside a vertical hole near the target. With the seismic source placed on the surface some distance from the hole, it’s possible to explore a region around the hole with ray paths that need to pass through the surface layer only once,” he says. “If the target is very important, we can drill a second hole and place the seismic source in it. Now we have even higher resolution because all of the ray paths are in the rock formations with low attenuation.”

The downside? “We can only make images of the region between the two holes. But if the target is extremely important in a limited area, we can use many boreholes and many images in the search. Given enough boreholes, a block of earth can be imaged with cross-well seismic reflection techniques.

A cross-well, seismic reflection image between test boreholes. The cavity is sharply seen because the shale stringers in the B-Salt (at the bottom of the image) are abruptly terminated. The cavity is approximately 375 ft. wide.

To site the Gordon Howie bridge, Turpening and Asiala chose a frequency band of 100Hz to 2 KHz—much higher than could be used with surface sources and surface receivers—for surveys on both sides of the river. This yielded high resolution seismic images, crucial for detecting cavities—and indeed they found one—on the Canadian side.

“The high-resolution imaging made it easy for us to spot missing shale stringers in the B-Salt layer in that image,” says Turpening. “This made the final selection of the bridge location simple. We found the cavity between boreholes X11-3 and X11-4, thus forcing the Canadians to chose Crossing B.  Obviously, the Michigan group had to, also, choose Crossing B.”

Two Michigan Tech faculty members have been appointed to a state panel on mining. On Friday, Governor Gretchen Whitmer announced the members of the new Committee on Michigan’s Mining Future. The formation of the committee was initiated by legislation introduced by State Rep. Sara Cambensy of Marquette.

Among those appointed by Whitmer were Snehamoy Chatterjee (GMES) and Timothy Eisele (ChE). Chatterjee was chosen to represent current or former research faculty members who hold a master’s or doctorate degree in mining or geology at a university in Michigan. Chatterjee said he’s “Overwhelmed and very excited” to serve on the committee.

Eisele, appointed as the designee of Cambensy, teaches minerals processing and metals extraction at Michigan Tech. He said the establishment of the Committee on Michigan’s Mining Future makes perfect sense. “Michigan is a major mining state, ranking in the top 10 states for mining activity, with an annual value of approximately $2.7 billion. Much of this material is used in-state for construction and industrial purposes, and it takes a prominent place in the economy of the state.”

Michigan Tech, which was created as a mining school, suspended the mining engineering program in 2004. This summer the major returned to the University with a new multidisciplinary mining engineering degree program. Chatterjee said the committee appointments will help the mining engineering program. “This appointment will not only help me professionally but also it will improve the visibility of our reinstated mining engineering program both to the potential employers and prospective students.

Eisele said it is important the University be represented on the state’s new mining panel. “Michigan Tech has a long history of working with the Michigan mining industry, and many of our students are employed by them. This committee will provide advice to the state legislature to ensure that the industry can not only operate in the state, but also find ways to utilize wastes constructively, and work with universities like Michigan Tech to develop and adopt new technologies that will reduce their environmental impact.”

The committee is charged with evaluating government policies that affect the mining and minerals industry, recommend public policy strategies to enhance the growth of the mining and minerals industry, and advise on the development of partnerships between industries, institutions, environmental groups, funding groups, and state and federal resources.

A total of 13 high school students from throughout Michigan are participating in a 5-day internship at Michigan Tech July 15-19, 2019. Faculty and their graduate students voluntarily host the students in engaging research activities during the week. The faculty’s department, along with the College of Engineering and College of Sciences and Arts, together provide a $600 scholarship for the student that covers their transportation, lodging and meals.

The interns work with Michigan Tech faculty and graduate students in their research lab or doing field work outside. During the week, students tour the Michigan Tech campus and local area, ‘experience college living’ in a residence hall, and meet students from across Michigan and beyond!

In Dr. Parisa Abadi’s Mechanical Engineering Lab, students will be 3D printing nanomaterials. Dr. Tara Bal in the School of Forest Resources and Environmental Sciences (SFRES) will conduct invasive species monitoring and forest health assessments. Dr. Will Cantrell in Atmospheric Physics will have the intern investigating why some clouds rain, while others do not.

Dr. Daniel Dowden in the Department of Civil and Environmental Engineering (CEE) has his intern investigating which technologies will allow buildings to sustain minimal damage and be easily repairable after large earthquakes. Four faculty–Drs. Deering, Waite, Oommen, and Gierke in Geological and Mining Sciences and Engineering are providing a broad introduction of mapping geological features, conducting geophysical surveys, and working to construct a 3-D model of a geological feature. Dr. Casey Huckins and graduate student–Chris Adams in Biological Sciences–are monitoring Pilgrim River and measuring the results of a fish survey in the lab. Dr. Daisuke Minakata in CEE and Dr. Paul Doskey in SFRES, along with graduate students, are researching innovative drinking water and wastewater treatment technologies.

Dr. Michael Mullins in the Department of Chemical Engineering (ChE) has his intern researching ways to remove PFAs contaminants from water. Dr. Rebecca Ong in ChE has her two interns investigating biofuel production from native grasses. Dr. Chelsea Schelly in the Department of Social Sciences and Dr. Robert Handler in the Sustainable Future Institute are measuring food, energy, and water consumption in residential homes and looking for ways to reduce household resource consumption. Dr. Kuilin Zhang and his graduate student Qinjie Lyu in CEE have their intern studying traffic data collection, traffic signal timing, eco-driving, and using traffic simulation software.

The program is coordinated by the Michigan Tech Center for Science and Environmental Outreach, in partnership with Summer Youth Program who provides logistical support and supervises the students in the residence halls in the evening.

Funding for the program is received from the Michigan Tech College of Engineering, the College of Sciences and Arts, the Department of Civil and Environmental Engineering, the Department of Mechanical Engineering-Engineering Mechanics, the Department of Chemical Engineering, the School of Forest Resources and Environmental Science, the Department of Biological Sciences, the Great Lakes Research Center, Youth Programs, and an anonymous donor.

The STEM internship program is coordinated by Joan Chadde at Michigan Tech Center for Science and Environmental Outreach.
