Rebecca Flowers, associate professor in the department of geological sciences at the University of Colorado, Boulder, presents “Deep-time Surface History of the North American Continental Interior, Kimberlites and Mantle Dynamics” Thursday, Feb. 22 at 4:30 p.m. in Thomas Steitz Hall of Science 102. The event is free and open to the public.

Flowers’ research focuses on the coupling of deeper Earth and surface processes, including questions related to the carving of the Grand Canyon and the uplift history of the southern African Plateau. While scientists are more familiar with plate tectonic processes that produce crustal deformation and the development of mountains at the boundaries between plates, large-scale “warpings” of the interior of the continent, including features like the Michigan Basin, which is responsible for the Niagaran escarpment, are less well understood. Current research suggests the surface of the continental interior responds to processes that originate at great depths in the Earth’s mantle.

The author or co-author of nearly 50 published research articles, Flowers joined the University of Colorado Boulder faculty in 2007. She earned a bachelor’s degree in geology from the College of William and Mary and her Ph.D. in geology and geochemistry from MIT.

Director/producer of award-winning documentary “Escarpment” to attend campus screening

What was the land like where Lawrence University’s northern campus — Björklunden — now stands several eons ago?

Roger Kuhns

The award-winning documentary film “Escarpment” will take viewers on a fast-paced journey through billions of years of natural history and the geologic and biologic past of eastern Wisconsin and the Niagara Escarpment region of the Great Lakes.

The screening, free and open to the public, is Thursday, Jan. 18 at 7 p.m. in Lawrence’s Warch Campus Center cinema. Roger Kuhns, who directed and produced the film, will attend the screening and be available for a question-and-answer session at the end of the film.

Winner of the 2017 Hollywood International Independent Documentary Award, the 92-minute film was shot on location along the entire length of the Niagara Escarpment, with a focus on Door County. Incorporating some animated sequences, it reconstructs ecosystems that existed when the Niagara Escarpment was formed, considers whether dinosaurs ever called what  is now Door County home and traces the path of glaciers as well as numerous other major events in the area’s geologic past.

Beyond just its geological narrative, Kuhns made the film as a way to educate, enlighten, and guide society toward better stewardship of the land and its resources while providing a glimpse of what a sustainable future might look like.

Roger KuhnsKuhns, who splits his time living in Door County and Mystic, Conn., is a man of multiple interests. A geologist by trade — he holds a bachelor’s and master’s degree in geology from Beloit College and Washington State University, respectively, and earned his doctorate in economic geology from the University of Minnesota — he also writes books and songs, makes movies, and is both a naturalist and a sustainologist.

He has lived throughout the world, including eight years in Africa. An active teacher and workshop leader, Kuhns remains current by conducting science and practicing sustainability as the director of his own company, SustainAudit, LLC.

Last fall, Lawrence received a significant grant to enhance sustainability efforts on campus.

Established in 1981, the Fellows program represents the highest level of recognition conferred by the Wisconsin Academy of Sciences, Arts & Letters. Drawn from a pool of statewide nominees, Fellows are elected for their extraordinary levels of accomplishment in their fields as well as lifelong commitments to intellectual discourse and public service.

One of 11 new Fellows named to the Academy in perpetuity, Bjornerud will be publicly recognized Sunday, April 17 at an awards ceremony in the Pyle Center on the University of Wisconsin–Madison campus.

Bjornerud, the Walter Schober Professor of Environmental Studies and Professor of Geology at Lawrence, joined the faculty in 1995. Her scholarship focuses on the physics of earthquakes and mountain-building. She combines field-based studies of bedrock geology with quantitative models of rock mechanics. She has conducted research in high arctic Norway (Svalbard) and Canada (Ellesmere Island) as well as mainland Norway, Scotland, New Zealand and the Lake Superior region.

“Marcia Bjornerud is an outstanding member of the Lawrence faculty and a great contributor to the quality of life in Wisconsin,” said Provost David Burrows. “Her election recognizes an important connection between academic research and scholarship and the scientific understanding of Wisconsin’s environment. The election to the Academy is richly deserved and is a symbol of the collaboration between Lawrence and the citizens of Wisconsin.”

Linda Ware, president of the Wisconsin Academy Board of Directors, said the Fellows program is a way to “honor the genuine treasures we have in this state—extraordinary people who show us the best of Wisconsin.”

“Every two years, we scan the state to find its most outstanding and creative people,” said Ware. “As part of our increasingly statewide reach for interdisciplinary excellence, we’re proud to recognize these brilliant and focused citizens who inspire people in Wisconsin and beyond.”

“[Marcia’s] election to the Academy is richly deserved and is a symbol of the collaboration between Lawrence and the citizens of Wisconsin.”

The founding director of Lawrence’s program in environmental studies, Bjornerud was named a Fellow of the Geological Society of America in 2003 and twice was named a Fulbright Senior Scholar, first in Norway (2000-2001) and then New Zealand (2009). She was named Outstanding Educator in 2011 by the Association of Women Geoscientists and was recognized with Lawrence’s Excellence in Scholarship or Creative Activity Award in 2007.

She is the author of the 2005 book, “Reading the Rocks: The Autobiography of the Earth,” and is a regular contributing writer to the New Yorker’s science and technology blog.

In 2012, Bjornerud was lead author on a pro bono report for the Great Lakes Indian Fish and Wildlife Commission on the geology of the Gogebic Range. The report was designed to serve as a free public document to provide baseline information about the potential effects of an open pit mine on the waters of the Bad River and the wild rice stands in the Kakagon Sloughs.

She earned a bachelor’s degree in geophysics from the University of Minnesota and master’s and doctoral degrees in structural geology from the University of Wisconsin-Madison.

Senior Brynley Nadziejka’s Research Recognized by Geology Institute

Brynley Nadziejka’s study of metamorphosed igneous rocks relevant to understanding earthquake risk in tectonically active regions earned honorable mention recognition in the student research paper competition at the annual Institute on Lake Superior Geology (ILSG) conference.

Senior Brynley Nadziejka earned honorable mention recognition at the annual Institute on Lake Superior Geology conference’s student research paper competition.

A senior from Kentwood, Mich., Nadziejka was recognized for her research at the Institute’s recent annual meeting held in Hibbing, Minn. This was the second year in a row Nadziejka was honored by the ILSG. She won the best student poster award in 2013. This was the fourth consecutive year a Lawrence geology student has been recognized at the ILSG’s annual meeting.

Nadziejka was among 33 student presenters from around the country at the annual conference. Amanda van Lankvelt, a 2010 Lawrence graduate currently pursuing a Ph.D. in geology at the University of Massachusetts, won the best paper award this year.

Nadziejka’s research focused on metamorphosed igneous rocks in Wisconsin’s Marinette County. The rocks represent the deep interior of the 1.8 billion-year-old Penokee Mountains, which formed in a tectonic collision when Wisconsin was at the edge of the ancient North American continent.

Micro-scale features on the rocks indicate slow ductile deformation at elevated temperatures and pressures, corresponding to depths of 7-9 miles in the crust. The rocks also contain pseudotachylyte, a glassy-type rock that is formed only by frictional melting during large earthquakes. The evidence reveals that as the mountains were growing, large earthquake ruptures sometimes propagated downward to depths where rocks are typically too warm to fracture.

The ILSG is a non-profit professional society that provides a forum for the exchange of geological ideas and scientific data and promoting better understanding of the geology of the Lake Superior region, whose rocks record more than 2.5 billion years of geologic time, more than half of Earth’s entire history.

The annual meeting draws American and Canadian geologists from academe, industry and state and provincial agencies for four days of presentations and field trips.

Junior Chelsea Johnson Awarded National Udall Scholarship

Chelsea Johnson has been focused on “making a difference”  since arriving on the Lawrence University campus in the fall of 2010.  Her efforts have not gone unnoticed.

Chelsea Johnson ’14

The Lawrence University junior from Avon, Ind., has been named one of only 50 national recipients representing 43 colleges of a $5,000 Udall Scholarship. Selected from among 488 candidates. Johnson was one of only two scholars chosen from a Wisconsin college or university.

Awarded by the Arizona-based Morris K. Udall and Stewart L. Udall Foundation, the scholarships are awarded to students committed to careers related to the environment, tribal public policy, or Native American health care.

“I’m interested in the connections between people and their environment and how to make that connection healthier,” said Johnson, an environmental studies and English major. “It’s not just about taking care of the planet, but also about taking care of the people who live on it. The environmental movement has to work on both sides of the equation.”

Co-founder of The Magpie

For the past two years, Johnson has served as president of Greenfire, the campus student environmental organization and is also the current student liaison to the campus’ Green Roots committee. She co-founded the Magpie, a once-a-term, student-run thrift store that collects used clothing and books for resale, with the proceeds used to support various national and international environmental groups.

“The idea behind the Magpie is to raise awareness on the clothing consumption industry, which encourages fast fashion at the expense of the environment and human rights,” said Johnson, who spent the 2012 fall term on the Sea Semester program, which included six weeks living on a sail boat in the Caribbean.

As a freshman, she helped organize a group of student volunteers to help out at local cat shelter and has been active as a “buddy” in Lawrence’s LARY tutoring program.

“Chelsea is both a student and steward of the environment,” said Marcia Bjornerud, professor of geology and Walter Shober Professor of Environmental Studies. “She embodies the new generation of environmental leaders — smart, passionate and pragmatic. We are so pleased that her academic work and activism have been recognized at the national level.”

Attending Orientation in Arizona

As a Udall Scholar, Johnson will participate in a four-day Scholar Orientation Aug. 7-11 in Tucson, Ariz., where she will meet with environmental policymakers and community leaders as well as other scholarship winners and program alumni.

“I’ll be around a lot of really smart people, which will be great,” Johnson said of the upcoming orientation.  “It’s really an honor and a blessing to be awarded this scholarship. I’m grateful for all the communities at Lawrence that have supported me in all my various projects. I look forward to giving back to those communities in the future.”

Johnson is Lawrence’s fifth Udall Scholarship recipient in the program’s 17-year history, joining Hava Blair (2012), Stephen Rogness (2003), Gustavo Setrini (2001) and Jacob Brenner (1999).

Founded in 1992, the Morris K. Udall and Stewart L. Udall Foundation is one of five federal foundations established by Congress. Among the missions of the foundation is to increase awareness of the importance of the nation’s natural resources, foster a greater recognition and understanding of the role of the environment, public lands and resources in the development of the United States and identify critical environmental issues.

Geologist Marcia Bjornerud Selected for National Outstanding Educator Award

Teaching, mentoring and research contributions to the study of geology have earned Lawrence University’s Marcia Bjornerud the 2011 Outstanding Educator Award from the Association of Women Geoscientists. She will be recognized Monday, Oct. 10 at the national meeting of the Geological Society of America in Minneapolis, Minn.

Presented annually since 1988, the award honors college or university teachers “who have played a significant role in the education and support of women geoscientists both within and outside the classroom,” including encouraging women to pursue careers in geoscience, providing field and laboratory experiences and serving as a positive role model.

Marcia Bjornerud

Honorees also are selected on the basis of their professional contributions to the study of geology, their involvement with professional societies and participation in science education programs in their community.

“This award is especially meaningful because so many current and former Lawrence students — both women and men — worked together to nominate me,” said Bjornerud, a structural geologist who joined the Lawrence faculty in 1995. “Teaching is a pleasure when one has such wonderful students.”

Professor of geology and the Walter Schober Professor in Environmental Studies, Bjornerud has honed her craft through more than 20 years of teaching experience, adopting the mantra “Teach less better,” with a focus on a more organic and deeper approach to the subject material, integrating and connecting concepts along the way. For more than 10 years, she has contributed to community science outreach programs for Fox Valley elementary and middle school students.

The recipient of Fulbright Senior Scholar Fellowships in 2009 and 2000 for field research in New Zealand and Norway, respectively, Bjornerud was instrumental in the creation of Lawrence’s environmental studies program in 2000 and served as its director for six years.

She is the author of the science textbook “The Blue Planet” and the 2005 book “Reading the Rocks: The Autobiography of the Earth,” in which she provides a tour of “deep time,” chronicles the planet’s changes and examines the toll human activity is exacting on Earth. She was elected a Fellow of the Geological Society of America in 2003 and was recognized with Lawrence’s Excellence in Scholarship or Creative Activity Award in 2007.

In addition to her award, Bjornerud also will make a presentation at the meeting on the question of when modern-style plate tectonics began on Earth. She will be one of seven Lawrence presenters at the national conference. Joining Bjornerud in research presentations will be associate professors of geology Jeff Clark and Andrew Knudsen, 2010 Lawrence graduate Katherine Cummings and current students Katharine Gurke ’12, Adam Kranz ’13 and Breanna Skeets ’12.
