To Dust We Shall Return?

Atmospheric Science Students, STS Students

By Lillian Knudtson

Weather affects all people, and it is important for meteorologists to understand a wide range of events to communicate effectively to the public. My capstone is a project designed to dissect a particularly interesting phenomenon, especially to South Dakota. I have chosen to do a case study of a particular dust storm known as a haboob. The storm I am focusing on occurred May 12th, 2022, and it impacted the eastern part of South Dakota. A widespread, long-lived thunderstorm called a derecho created the haboob beginning in the south central portion of Nebraska and traveled north and east towards Sioux Falls. It sustained winds of 80 miles per hour, and the highest recorded winds of the event were 107 miles per hour. This storm is a good example of what is possible and can become a sample case for the future.

A haboob is a giant dust storm. It is named after the Arabic word habb, meaning “blown.” This type of storm is most common in the Middle East and Northern Africa, where is it historically arid. But haboobs are also well known in the Southwestern United States and are becoming an occurrence in previously unlikely places as well. Haboobs are created from loose particles that are picked up by strong winds caused by storms like monsoons or derechos sweeping across the surface of the earth. The massive amount of precipitation associated with these events evaporate, which is a cooling process, so cool air called a gust front accelerates out in front of the storm at a fast rate, picking up particles and building a wall of air and dirt. The particles are mostly less than 10 micrometer pieces of dirt, dust, and sand, but they can be as large as a pea, and the wind can pick up other debris along with it. These walls of air and dirt can reach grow to 5000 feet tall and 100 miles wide, and they can move at 60 miles an hour (Eagar, Herckes, Hartnett, 2016). Overall it is a phenomenon that is quite terrifying.

It Spins Me Right Round: What’s The Big Deal With Tornadoes?

Atmospheric Science Students, Environment, STS Students

By Cory Schultz

If you look at the annual average number of tornadoes per country, the United States reigns supreme, whether we like it or not. And if we look at South Dakota, the state is not without its share of tornadic activity. For instance, as Dennis Todey, Jay Trobec, and H. Michael Mogil write, “A massive outbreak of tornadoes placed the state in the severe weather record book on the evening of June 24, 2003” (19). On that day, sixty-seven tornadoes touched down over a 6-hour period, a single-state record tornado occurrence.

So, you may be thinking to yourself right now, “I live in the Black Hills region of South Dakota. We don’t have a problem with tornadoes.” Well, what if I told you that tornado activity has increased in the Northern Black Hills of South Dakota in the last decade? This increase in activity is not typical for the Northern Black Hills, since only nine tornadoes have been reported in this region since NOAA started gathering tornado data in 1950. What makes this even more alarming is that, of these nine cases, four have occurred in the last decade. This increase is the focus of my capstone with my two-part research question: Do the Northern Black Hills tornadoes that occurred in 2015, 2018, and 2020 have any similar characteristics to each other? Will this help determine when new tornadoes will form over the same region?

STS Faculty Profile: Kyle Knight

STS Faculty Profile

Kyle Knight is Department Head and Professor of Sociology.

What’s your area of expertise? What do you primarily research and/or teach? And what drew you to this field?

I’m an environmental sociologist. I primarily research the human dimensions of environmental change, which includes the social causes, consequences, and responses to environmental problems. Besides introductory, statistics, and methods courses in sociology, I’ve also taught courses on environmental sociology, environmental justice, and society and climate change. My research has lately focused on social patterns in climate change public opinion. For example, my most recent publication examined how outdoor recreation, such as hiking and birdwatching, might foster greater concern for climate change. My initial interest in sociology was motivated by questioning the centrality of materialism and consumerism in our society, and that blossomed into a drive to understand how we might achieve a more sustainable and equitable future.

What’s one of your favorite courses, topics, or specific texts to teach? Why?

One book I’ve used in my classes for a while now is Andrew Szasz’s Shopping Our Way to Safety, which I think provides an excellent illustration of how treating systemic social problems as individual-level issues to be solved by consumers not only doesn’t solve these problems but actually makes them worse. One of the biggest challenges in teaching environmental sociology is to get across the point that environmental problems are, at their root, social problems, and this book usually does the trick.

What’s something you’ve done that you’re really proud of?

While working on my Ph.D. at Washington State University, I co-authored and published an article with a fellow sociology graduate student and we received a departmental award for it. It was at this moment that I began to feel like a real scholar, and I continue to be proud of the work we did on our own to make it happen.

Tell us about a book you’ve read recently, a movie you’ve seen recently, or another work of art or media you’ve engaged with recently that you really enjoyed and would like to recommend.

I am a big music nerd and love all kinds of genres and traditions. I listen to music all day long, especially while working in my office, and enjoy reading album reviews. My musical tastes run the gamut – some of my favorite musical artists lately are Jake Xerxes Fussell, Yasmin Williams, Madlib, Cassandra Jenkins, Ben Chasny, Julian Lage, and Protomartyr. Right now, I’m fascinated by Marina Herlop’s new album titled Pripyat, which is named after the Ukrainian city abandoned in the aftermath of the Chernobyl nuclear disaster. Herlop is a classical pianist and experimental producer from Barcelona, and this album creates a wordless, other-worldly soundscape that is just completely captivating. My favorite track is “Shaolin Mantis” but the choir version of “Miu” is a close runner-up.

Tell us something about yourself outside of work. What do you enjoy doing? What’s a detail about you that Mines students might not already know?

I’m pretty boring and just enjoy spending time with my family outside of work. We especially like to hike, camp, and ride bicycles. We’re very excited to get to know the Black Hills and to eventually ride the Mickelson Trail when it’s not so hot!

Planting Seeds: Anchoring Ethics in the Dirt

Classes, Environment, teaching

By Christy Tidwell

My Environmental Ethics & STEM class asks big questions about knowledge, values, justice, and responsibility – both individual and systemic – related to environmental issues. Although I try to situate these conversations in specific, real-world examples, they can still sometimes seem abstract or beyond the scale of my students’ reach. They may wonder what they can do to address climate change, for instance, or to change corporate policy.

But they can, of course, make a difference, and we look for ways to identify the actions they can take (again, not just individually but within larger contexts). In the meantime, to help connect us more fully to the environment, this semester I asked my students to plant seeds and to do their best to grow them and keep them alive. It’s my hope that working to protect and nurture one small plant will give the class a personal connection that issues of pollution, plastics, or water rights may not always have.

Searching for a Place to Live with the Most Ice and Thunderstorms

Atmospheric Science Students, STS Students

By Steven Slater

Steven is majoring in Atmospheric and Environmental Sciences, and his primary interest is extreme weather.

Ever since I can remember, I enjoyed watching the rare thunderstorms whenever they occurred in Western Washington. I often had to wait a year or more between seeing individual lightning bolts. I often watched The Weather Channel as my main source of weather-related content, whether it had to do with storms or snow. My mind was blown as I watched the reported snow totals rise close to 12 feet for the lake-effect vent in February 2007.

The lowlands of Western Washington don’t receive much snow, so I had to wait for that, too, though it happened more frequently than thunderstorms. I was an advocate for receiving as much snow as possible in the shortest time. The biggest event I experienced in Washington was in December 2008, where I remember playing in ~15 inches of snow at the peak of the event.

Balancing Expectations: Preserving the Nature and History in South Dakota

STS Students

By Louise Swanson

Louise is majoring in Science, Technology, and Society with a minor in Environmental Science. She plans on working with the parks system or in museum work.

When I was growing up, I spent my weekends going to ghost town sites around the Black Hills with my father. Each time we went to Spokane we made guesses as to whether or not the old community center that Elizabeth Cady Stanton spoke at would have collapsed (a couple of years ago it did) or if the Two-Bit Mill would still be standing (about 10 years ago it was bulldozed into a nearby ravine to better allow for nature to return to the area). Meanwhile, I watched as the Gordon Stockade was refurbished and preserved for visitors to come and see where the Gordon Party lived while in the Black Hills.

In college I have taken both history and environmental science classes and worked for a year at The Journey Museum, and I have only become more curious about how the decision to preserve some things and not others is made and how agencies decide whether to prioritize the environment or the history of an area. The optimist in me also hopes that maybe sometimes we don’t have to choose. Maybe, sometimes there is a way that environmental conservation and historic preservation are linked.

Environmental Literature & Culture: Spring 2022 Course

Classes

By Christy Tidwell

What is nature? What do you imagine when you think of nature? What are the qualities of nature (better yet, of Nature with a capital N)? 

Pause now and think about that for a minute. 

Seriously. 

What is the image of Nature you hold in your mind? Picture it.

Did you imagine something like that? Maybe not that exact image, but something similar? If so, consider this response more fully. What are the qualities of this representation of nature? It’s beautiful. It has lots of elements of the natural world (I know, that seems circular, but stick with me), like trees, mountains, a lake. It’s pure and untouched. It’s wild. Notably, there are no humans in this image.

Spooky Science at the Movies!: Week 2

Environment, Film, horror, Humanities

By Christy Tidwell

Horror movies are often defined by their monsters. Sometimes these monsters are terrifying beasts that give us nightmares (like Guillermo del Toro’s Pale Man from Pan’s Labyrinth or Pennywise from Stephen King’s It), sometimes they’re kind of silly (like the rampaging rabbits in Night of the Lepus), and sometimes they’re surprisingly sympathetic (like Frankenstein’s Creature).

In any case, monsters demonstrate something about both the world we live in and what we fear. In the 1950s, people feared nuclear war; now, we fear climate change. The two horror movies I’m recommending for this week directly address those fears, presenting viewers with monsters that embody the harm of nuclear warfare/testing in one case and that are the direct result of climate change’s superstorms and unpredictable weather patterns in the other.

Whether We’re Exploring Space or the Ocean, Stories Fuel Science

The Double-Edged Sword

By Olivia Burgess
The Double-Edged Sword

My Introduction to Science, Technology, & Society class recently discussed “space ethics,” and part of that conversation involved weighing the costs and benefits of prioritizing space exploration over other alternatives – most notably, ocean exploration. 

For part of our discussion, I grouped my students into two different teams and gave them a task: one team had to decide how to convince the public to support funding space exploration, while the other team needed to convince the public that it was better to support ocean exploration.

Learning to See the Land

Environment, Humanities

By Bryce Tellmann

Many, perhaps most, of the students I teach are from the Dakotas, Nebraska, and Kansas, all states that are frequently referred to as “Plains States.” (We can spend a lot of time debating the inclusion criteria for a state to qualify as a “Plains State,” but that’s a different post.) At some point in the semester, I usually ask them, as a group, to complete this sentence: “The landscape of my state is ______.” Almost invariably, I am met with a unison chorus of “flat!” or “boring!” This response is more than mere topographical observation.

I grew up in western North Dakota, seeing the landscape much as my students do: essentially flat and nondescript. Not until years later did I realize that I lived in a very dramatic landscape: knuckles of stone push their way out of ancient hills, the last evidence of resistance to glacial domination thousands of years ago. Stretches that appear flat are actually cascading downward, racing toward whatever rare stream or coulee will collect the sparse rainfall. The grass itself frustrates efforts to touch the ground, as one must dig through several inches of dense, matted undergrowth to find soil. This immense complexity is most evident at dawn and dusk, when the extreme angle of sunlight throws easily elided variation into sharp relief.
