Mines Researcher Adds to Study on Oyster Tissue Abnormalities

An oyster cluster collected on the coast of Louisiana by Dr. Laurie Anderson as part of a study on the long-term impact of the Deepwater Horizon Oil Spill

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.

South Dakota Mines Constructs Living Laboratory on Campus

Mines civil and environmental engineering graduate student unrolls hay on one of the test plots.

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 wi...

First Ph.D. in New Mining Engineering Program Builds Computer Program to Improve Underground Mine Safety

Ankit Jha is the first graduate of South Dakota Mines’ new doctoral program specializing in mining engineering.

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...

Dinosaurs: A Catalyst for Critical Thought

Darrin Pagnac, Ph.D., holds a model of a Triceratops skull.

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...

Mines Researchers Explore Hydraulic Fracturing to Expand Geothermal Energy

Liangping Li, Ph.D., (left) and Bill Roggenthen, Ph.D., (right) shown here in the EGS Collab at the 4850 level of the Sanford Underground Research Facility.

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 ...

SD Mines Paleontologist Lands Fulbright Scholarship to Study Invasive Species Impact

SD Mines alumnus Broc Kokesh has received a Fulbright Scholarship to study invasive species impact in Jamaica.

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...

SD Mines Energy Resources Initiative Builds Momentum as US Production Peaks

Nine SD Mines students join Energy Resources Initiative director Dan Soeder on a hydraulic fracturing operation during a visit to the Bakken oilfields of North Dakota. The trip was funded by Halliburton.

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 dioxid...
