Gokce K Ustunisik, Ph.D., an associate professor in the Department of Geology and Geological Engineering at South Dakota Mines, and Alexander Rogaski, who completed his master’s degree at Mines under Ustunisik, have produced minerals found on Mars by experimentally mimicking the conditions in Martian fumaroles, or vents found in areas of volcanic activity.

Their work, published in the journal of Meteoritics and Planetary Science, indicates ongoing volcanism on the red planet. Scientists only recently discovered that Mars may have areas of active volcanos. “Both ...

South Dakota Mines has created a new multidisciplinary Center for Sustainable Solutions. The center will be a hub for research and development around sustainability including water quality, emerging contaminants, agriculture, infrastructure, carbon capture, biofuels, bioplastics, environmental stewardship and more.

“As society faces increasingly complex problems, providing sustainable solutions requires integrative partnerships and approaches that build convergence of many disciplines with research and support for stakeholders at all levels,” says Lisa Kunza, Ph.D., an associate professor in the Department of Chemistry, Biology and Health Sciences and the director of the new center at Mines.

On the night of June 12, 2022, a storm system began dumping rain on the Beartooth Range of northern Wyoming and southern Montana. Over the next 24 hours, about four inches fell on the still snow-covered peaks of the northern Rockies. The rain-on-snow effect drove a rapid loss of mountain snowpack. Because of this, streams and rivers quickly swelled out of their banks, and quiet mountain towns were slammed with flash floodwaters. Bridges, roads and homes in and around Yellowstone National Park were swept away in the torrent, isolating communities and stranding tourists.

Teams of first responders were mobilized in the hours and days after the disaster. Among them was a specialized group of scientists who study civil infrastructure. “Our group of students and researchers were loaded with scientific equipment and on the road in 24-hours after receiving the call to help assess and map flood damage,” says Bret Lingwall, Ph.D., who is an associate professor of civil and environmental engineering at South Dakota Mines.

Lingwall is one member of the National Science Foundation’s Geotechnical Extreme Events Reconnaissance (GEER) effort. This organization includes teams of scientists across the country who spring to action in the wake of disasters to collect perishable post-disaster data. Their goal is to capture critical data on infrastructure and disast...

This South Dakota Mines Research Blog article is based on a press release from the California Academy of Sciences published here.

On April 20, 2010, the Deepwater Horizon (DWH) petroleum drilling rig exploded off the coast of Louisiana, resulting in the world’s worst oil spill in history with more than 4 million barrels of oil released into the Gulf of Mexico. Though the short-term impact of the oil spill on local wildlife was widely researched among scientists and discussed in the media, there has been relatively little research on the long-term effects of the disaster.

Laurie Anderson, Ph.D, professor and head of the Department of Geology and Geological Engineering at South Dakota Mines, collected Eastern Oysters from the Gulf Coast. A second set of oysters was collected from the Chesapeake Bay area that were unaffected by the Deepwater Horizon oil spill.

 “We were able to collect live specimens of common coastal species of snails, mussels, and oysters after the spill but prior to landfall of the spill throughout coastal Louisiana and Dauphin Island, Ala.,” says Anderson.

Anderson joined other researchers from the California Academy of Sciences, Nova Southeaste...

South Dakota Mines is home to a new living laboratory that is located on a hill above the main campus. This long-term study will help students and the community understand how vegetation and ground cover impacts soil erosion, water quality, ecosystems and our shared natural resources.

The study area is a steep exposure of the Belle Fourche Shale rock formation that had been a problem area for erosion and contained little-to-no vegetation. The living laboratory includes over 20 small plots in a grid that have different erosion control treatments, ranging from engineered products to low-tech solutions such as hay cover or mulch. Each treatment option was designed and built by undergraduate student researchers with the assistance of faculty and instructors. The study is funded by the West Dakota Water Development District (WDWDD). The elected board is one of seven water development districts in the state, organized for the purpose of promoting conservation, development and management of resources.

Each year, students in the Department of Civil and Environmental Engineering will collect data on the treatments laid out in the living laboratory. Over the coming years, the data collected by students will h...

SERL instruments enable the chemical characterization of a wide range of sample types including natural waters, biological materials, roc...

Ankit Jha, Ph.D., is the first graduate of South Dakota Mines’ new doctoral program in Mining Engineering. 

Dr. Jha’s research, conducted under Associate Professor Purushotham Tukkaraja, Ph.D., included a new computer system that integrates and enhances underground mine ventilation, safety, communication and rescue operations. The concept involves developing a command center with software that allows for real-time tracking of individuals on digital maps inside a mine. It also records real-time sensor data from the atmospheric monitoring system within the mine. The data collected with specific algorithms from mine ventilation engineering and computer science were utilized in developing the software. 

When the system alerts operators of danger, it highlights the fastest and safest path for a mine rescue and recovery operation. Jha’s research also examined the flammability of ventilation ducts in underground mines and made recommendations for improvements.  Furthermore, Jha investigated efficient ventilation designs to mitigate radon emission in underground metal mines by using experiments and computational fluid dynamics simulations. 

In his dissertation, Jha writes, “As mine rescue operations are stressful because human lives are at stake, it is not surprising that pertinent information could be missed, which could adversely affect the rescue operati...

Since the mid-1800s dinosaurs have been a source of fascination and inspiration — from children’s coloring books to Hollywood blockbusters, these extinct animals hold a unique place in the American psyche. The immense popularity of dinosaurs also makes them an excellent conduit for teaching the critical thinking skills needed in basic science and engineering literacy.

Darrin Pagnac, Ph.D., is a South Dakota School of Mines & Technology associate professor of geology specializing in paleontology. His latest work, “Dinosaurs: A Catalyst for Critical Thought,” published by Cambridge University Press, shows that passion for dinosaurs, when properly directed, can trigger interest in science and be used to develop critical thinking skills.

Each spring Pagnac teaches a course called “Dinosaurs,” which attracts a wide range of students from various fields of study. “We have a number of students who get fired up emotionally about dinosaurs,” he says. In this class, Pagnac helps students confront preconceived notions that he calls “Jurassic Park Syndrome.” This is where student’s views of paleontology and sciences are shaped...

The use of hydraulic fracturing (or fracking as it’s commonly called in the press) has been a topic of contention in the oil and gas industry. However, researchers believe fracking can also be used at depth in hard rocks that contain no oil or gas to improve geothermal energy production. The process could enhance the use of the earth’s own heat as a source of clean energy.

Liangping Li, Ph.D., an assistant professor in the Department of Geology and Geological Engineering at the South Dakota School of Mines & Technology, has received an award from National Science Foundation (NSF) for his research entitled “Inverse Methods of Hydraulic Fracturing for Enhanced Geothermal Systems in a Deep Mine.” Li is working alongside projects already underway at the Sanford Research Facility (SURF) including kISMET (permeability (k) and Induced Seismicity Management for Energy Technologies) and the Enhanced Geothermal Systems (EGS) project. Hydraulic fracturing research at SURF uses no chemicals, so unlike some fossil fuel fracking operations, the fracking fluid used in these ...

South Dakota School of Mines & Technology alumnus Broc Kokesh has received a Fulbright U.S. Student Program award from the U.S. Department of State and the J. William Fulbright Foreign Scholarship Board. Kokesh graduated with a master’s degree in paleontology in May. This Fulbright award takes him to Jamaica.  

Kokesh is studying how an ecosystem responds following the introduction of an invasive species. His work compares diversity between living mollusk (clams, snails, etc.) communities and co-occurring dead shells from the Kingston Harbor. His research examines the ecological effects of invasive green mussels, which were introduced in 1998 via ballast water from shipping traffic. However, since about 2010, green mussels appear to have receded in abundance for reasons unknown. Questions remain as to how the invasion affected native fauna, and Kokesh brings a paleontological perspective by focusing on dead shell diversity. Human-introduced invasive species are a global problem and this research may lend insight to invasive species management and impact in other parts of the world. 

The Fulbright Program is the flagship international educational exchange program sponsored by the U.S. government and is designed to build lasting connections between the people of the United States and the people of other countries. The Fulbright Program is funded through an annual appropri...

One of the primary goals of the South Dakota School of Mines and Technology’s Energy Resources Initiative (ERI) is to conduct research that improves the efficiency and reduces the environmental risks of producing fossil fuels while providing energy security for America.

While the country’s oil and gas industry has been in a down cycle, recent data shows US production is reaching a peak not seen since the 1970s due to increased development of shale oil and gas.  Dan Soeder, the new ERI director, is an industry expert on development of shale resources and reserves. Soeder is less than a year into his new position at SD Mines. He has spent this time quietly putting down roots to firmly establish the program. Soeder has been developing research projects, building relationships with industry and pursuing funding. The aim is for SD Mines to grow as a valuable industry resource, both in supplying future engineers for this sector and in providing solutions for efficient and safe oil and gas production.

Soeder left the U.S. Department of Energy last spring to become Mines’ first ERI director, bringing with him 30 years of experience as a hydrologist and a geologist, with a particular focus on shale gas, water resources, and sequestration of carbon dioxide.

The ERI was initially announced in 2014 – when th...
