Geology Students Study Tectonic Rifts

note: the following is a news release from Oklahoma State University

Four Oklahoma State University geology students traveled to Malawi in Africa to study tectonic rifts last summer thanks to a 2014 grant from the National Science Foundation.

Dr. Estella Atekwana, geology department head, and Dr. Daniel Laó-Dávila, a geology professor, took four students to Karonga, Malawi, to explore the East African Rift that extends for thousands of miles along the continent’s edge bounded by the Indian Ocean.

“People don’t know what rifts are,” Atekwana said. “There used to be one big continent, called Pangea; it’s because of rifts that the continents broke apart. Malawi has a young rift system and is the go-to place to study the entire rift process.”

The grant allowed the Boone Pickens School of Geology to create an international program for its students, sending a total of 12 students in groups of four for three years. The trips allow the students to collect geological data and gain cultural experience outside of the university.

“The last thing I was expecting was a culture shock,” said Sam Dawson, a graduate student from Davidson, North Carolina. “Seeing what life was like in a developing country was eye-opening. The people are so happy. I saw some kids playing with simple toys for hours on end.”

Other students included undergraduates Tiara Johnson, from Midwest City, Oklahoma; Bryan Clappe, from Chelsea, Oklahoma; and Courtney Hall, from Broken Arrow, Oklahoma. Clappe has since enrolled in the graduate program. The trip lasted from July 14 to Aug. 11, with students working five or six days a week from 8 a.m. to 8 p.m. This international opportunity will help make the students more competitive for job opportunities after graduation, according to Atekwana.

“It was a win-win experience,” she said. “Students can do research from the beginning of a rift and learn a lot. They don’t just learn about the science, but what it takes to collect it, to learn new cultures, meet new people. Students need to be competitive in the global economy. This gives them the advantage because they’ve now been there and done that.”

Karonga is a small town in northern Malawi, with a population similar to Stillwater. In 2009, there was a major earthquake in the town. Atekwana said the earthquake meant the rift was still active, so they needed to find the earthquake zone and image it.

“It’s sort of like a CT scan but of the underground,” she said.

In previous years, the geology department has led trips to Zambia and is looking into more places in the future, including Uganda and Ethiopia. But Laó-Dávila says there are other places in the U.S. that can be explored as well.

“There’s an ancient rift in Oklahoma not many people know about,” he said. “It’s in the southwest part of the state by the Wichita Mountains. Other places we can explore are the Rio Grande Rift, in New Mexico, and the Mid Continent Rift System that spans across Kansas, Iowa, Minnesota and Michigan. It’s one of the oldest examples of a rift, at about 1.1 billion years old.”

But the trip wasn’t all work and no play. The group took trips to see different national parks in Malawi, including the Nyika National Park, a major tourist destination for the country. The group also toured the Cultural and Museum Center Karonga as well as going on safari rides.

“I woke up the next morning to see zebras out of my window,” Dawson said. “So that was pretty cool. I enjoyed getting to learn more about the geologic and cultural history at the museum as well. And there were so many beautiful sites to see.”

Some of the struggles the group had throughout the trip included living conditions and Internet connectivity. The hotel they stayed at cost $6 a night. Dawson said sometimes he didn’t have a shower, and if he did, there was only cold water available. Other problems included the electricity going on and off and waiting days to get Internet connectivity.

“That made it difficult for us to record our data or get connected to our resources on campus when we needed to.”

In the end, the experience was one that Atekwana believes changed the students’ lives. She said it showed them how people get by with a tenth of what Americans have and to learn how to get good scientific data from it.

“I recommend people not being closed minded as far as interacting with the culture goes,” Dawson said. “I did not expect to become such great friends with our driver, Kennedy. He taught us some of the language, including some pick up lines for us to use. We paid him $30 a day for a month, and he said that money would pay for his entire living expenses for six months. If I go back, I’d definitely try to find him again.”

The students reported on their trip at the American Geophysical Union’s 2015 Fall Meeting December 14-18, where 24,000 attendees met to present research and discover more about the latest happenings in their fields. For more about the Boone Pickens School of Geology, visit geology.okstate.edu.

Science Research in Oklahoma

There is so much science happening right under our noses here in eastern Oklahoma. The OSU Center for Health Sciences is just one example. You’ll find research into biomedical and forensic science, healthcare, medicine, and ,my personal favorite, paleontology.

The cool thing is OSU-CHS has a fantastic resource to help you stay on top of what they’re doing. They call it the Research Spotlight. There are videos and information all on kinds of topics. The video below is one example of the research taking place right here in Tulsa!

 

 

Adventures on Turkey Mountain

Turkey Mountain is a popular place to hike, walk, or ride a bike. Thousands of people go there every year but I wonder how many have stopped to think about the science that’s all around them.

Dr. Stanley Rice recently gave me a personal science tour of Turkey Mountain. He showed me tree fossils and explained that Turkey Mountain is the only place in Oklahoma where a certain oak tree grows. This just shows that science is everywhere. It’s also why you’ll often find me checking out rocks, I’m looking for fossils and evidence of ancient Earth.

This is important-If you find fossils on Turkey Mountain please do not remove them.

(Dr. Rice has been featured before on SIO…click here to see his impersonation of Charles Darwin.)

 

Free Science Workshop for Teachers

Attention all elementary and middle school teachers…here’s a great opportunity to learn about life sciences and do a little fossil hunting.

Janessa Doucette is a PhD candidate at the University of Oklahoma. She’s hosting a free workshop series called Oklahoma Educators Evolve. It’ll take place on Saturday Oct. 17th and Saturday Oct. 24th. The first one is a fossil hunting trip to the rich grounds at White Mound in Sulphur. The second is a workshop in Oklahoma City. You’ll study the nature of science, biological concepts, and paleontology, “We will provide you with a foundation for these concepts, as well as provide you with a variety of ways to successfully teach these topics in your classroom. Participants will leave this workshop with their very own classroom collection of fossils and fossil casts with which to enjoy science learning with their students!”

What’s a Graptolite?

Remember that Golden Spike? (Click here or scroll down one story.) It marks a boundary between two geologic time spans. In a nutshell, it’s where and when (geologically speaking) a  species makes its debut in the geologic record.
The Oklahoma spike is where Diplacanthograptus caudatus was found. It was a small aquatic animal called a Graptolite that floated around thanks to ocean currents.
Kyle Hartshorn with Dry Dredgers sent along some pictures of Graptolites that were found in Oklahoma. They’re tiny and look like pencil marks in the rock. Hartshorn told me, “Graptolites came in a variety of shapes: long and thin, short and wide, wishbone shaped, spiraled, and more.  There were quite a few forms at the places we went.”

This pic below is of a conodont. It was an small creature that kind of looked like an eel. The conodont below is the yellow-orange speck inside the circle. That circle is about the size of a dime and was drawn around the fossil to help spot it. Conodonts are extremely hard to spot with the naked eye.

These images are why I can’t help but examine rocks when I’m outside. You never know what you’re going to find, fossils can be all shapes and sizes!!

A Golden Spike in Oklahoma Marks the Spot

A Golden Spike in Oklahoma marks a geologic boundary that has the attention of scientists across the world. The picture below shows what’s called the Katian Golden Spike. It’s been placed near Atoka (about 45 miles southeast southwest of McAlester).

So what’s up with a big gold spike being hammered into the rocks? Well, long story short- it marks the beginning of a span of geologic time. This particular spike represents the start of the Upper Ordovician Katian Stage. The Ordovician Period is a span of time that lasted from about 485-million years ago to 443-million years ago. The Katian Stage was the second to last stage of the Ordovician. It lasted about 8-million years.

The spike marks a Global Boundary Stratotype Section and Point or GSSP. The location for a spike is determined by the first appearance of a particular species in the geologic record. In the case of the Katian Golden Spike, it marks the first place where Diplacanthograptus caudatus was found…a small aquatic animal that just floated around.

Kyle Hartshorn is with Dry Dredgers, “the oldest continuously-operating fossil club in North America”. He was also part of a group that recently toured Oklahoma’s geology and placed the spike in Atoka. He says these kinds of fossils look like little zippers or feathers, “These floating colonial animals were widely distributed by ocean currents, making them excellent tools for stratigraphic correlation.  Other wide-ranging planktonic fossils are also found at the site, including conodonts (teeth-like structures from tiny lamprey-like primitive fish) and chitinozoans (little sac-shaped fossils of unknown origin).”

The placement of a Golden Spike is mostly ceremonial, according to Hartshorn, but it does help scientists who do research there in the future. There are Golden Spikes placed around the world but only six , including the Katian Spike in Atoka, are in the United States.

 

 

This Scientist Is OK- Dr. Stanley Rice

Dr. Stanley Rice is a botanist and professor at Southeastern Oklahoma State University in Durant. He’s one of the more active scientists in Oklahoma in terms of public outreach. He works with Oklahomans for Excellence in Science Education and he’s well known for channeling his inner Charles Darwin (check it out at the 1:50 mark) and click here to go to his YouTube channel.

Dr. Rice loves science and has made it his life mission to share his passion. He says, “What’s most important to me is that people can understand why science is important and how that fits in with their lives and their responsibility to all of humankind and to all the world. All the little things we do matter and science helps us understand how those little things matter.”

 

 

Camp Quest

Here’s a great chance for you and your child to learn about science and take in the great outdoors this summer. It’s called Camp Quest. The camp focuses on science and caters to the non-religious. Here’s how it’s described on its website, “The purpose of Camp Quest is to provide children of freethinking parents a residential summer camp dedicated to improving the human condition through rational inquiry, critical and creative thinking, scientific method, self-respect, ethics, competency, democracy, free speech, and the separation of religion and government.” 

The kids learn about everything from DNA to biology. They also go canoeing and learn archery. I spent some time at the camp back in my TV days and it looks like a lot of fun. Click here to see that story from 2013.

You can register for the camp here. They’re also looking for adult volunteers. Check out what the president of Camp Quest Oklahoma posted on Facebook about her experience as a volunteer, “I’ve watched these same children blossom from shy, quiet, and immature kids to outspoken and proud young adults. The best part is returning and seeing these kids year after year and seeing how they’ve grown and matured. These kids let me know that they are going to change this world into a better place.

Summer of Science

How about a summer of science for your high schooler (or 8th grader)?!?! OK Higher Ed is offering a fantastic opportunity for students who will be in 8th-12th grade next year. It’s called the Summer Academies.

A total of 26 academies will be held at 17 college campuses across the state throughout the summer.  Topics include biology, engineering, math, aeronautics, meteorology…you know, all the STEM stuff. Best of all, it’s FREE!!!

This Scientist Is OK- Kyle Davies

Kyle Davies is a paleontologist and a fossil preparator at the Sam Noble Oklahoma Museum of Natural History. He builds the displays you see on the museum floor. He most recently helped prepare Aquilops americanus display which debuted in February.

Davies is one of those people who’s living a childhood dream. He says all he ever wanted to do was build fossil displays. How abut that? Now he’s doing it and that makes him an OK scientist.
