Diane McKnight: Climate change increases metals concentrations in streams, study finds Anonymous (not verified) Thu, 05/23/2024 - 15:48

A recent study points the finger at climate change as the cause of increasing metals concentrations in ��ֱ��’s high mountain streams. These findings have implications for local ecosystems and the water supplies of mountain communities.

Diane McKnight is being recognized with the highest honor bestowed upon faculty in the University of ��ֱ�� system: Distinguished Professor, which is awarded to faculty for exemplary performance in research, teaching, and service.

A professor in the Department of Civil, Environmental and Architectural Engineering; the Environmental Engineering Program; and the Institute of Arctic and Alpine Research, McKnight has spent her career studying ecological, biogeochemical and hydrologic processes in lakes, streams and watersheds, primarily in polar and mountain regions.

“I’ve been interested in hydrology and ecology since I was in college in the ’70s,” McKnight said. “It’s fascinating work and directly impacts our understanding of water quality and the influence of climate and hydrology.”

Her research has dramatically expanded knowledge about the relationship between natural organic matter and heavy metals in streams and lakes and led to her election to the National Academy of Engineering in 2012.

Much of her field work has been in extreme environments, especially polar regions – she has been to Antarctica more than two dozen times.

“The lessons that we learn in Antarctica get plugged in more broadly. The algae growing in streams there are very similar to algae growing in ��ֱ��, but we can understand more clearly what’s happening there because there is no signal coming in from plants in the meadow or in the forest because there aren’t any meadows or forests,” she said. “They’re like naked streams. We can learn about fundamental processes.”

McKnight is one of the founding principal investigators of the McMurdo Dry Valleys Long Term Ecological Research Program in Antarctica, and she serves as chair of the National Science Foundation’s LTER Science Council.

“As we think about green engineering for green infrastructure, people are putting more value on sustaining rivers to help deal with floods in cities and various pollution issues. These ecosystem concepts are also very relevant to dealing with hazardous algal blooms,” she said. “There’s a realization that some of the water challenges can’t just be addressed by treating drinking water at the utility plant. We need a more holistic approach, a bigger view.”

McKnight earned her PhD in environmental engineering at the Massachusetts Institute of Technology in 1979 and spent 17 years at the U.S. Geologic Survey, conducting field and laboratory research, before joining ��ֱ�� Boulder in 1996.

“I was at the USGS and had grad students working in my lab from ��ֱ�� Boulder, ��ֱ�� State, and the School of Mines. I really wanted to teach stream ecology. It’s an exciting field and the students are excited, too,” she said.

She was one of the founding faculty members of ��ֱ�� Boulder’s Environmental Engineering Program when it began in 1998 and has been part of its growth as an important discipline in the College of Engineering and Applied Science.

“We have as many students in a single environmental engineering class now as we had in the whole program when it started. It’s to ��ֱ�� Boulder’s great credit that this program has been supported and evolved,” she said. “I am glad to be part of how we deliver this curriculum and train our students. I am so indebted to my colleagues at INSTAAR and in environmental engineering who have been very supportive.”

Although McKnight is in the middle of a semester-long sabbatical, conducting remediation research on the hydrology of the Florida Everglades, she is eager to be back on campus for the spring 2022 semester.

“It’s a great privilege to teach a class and to advise and mentor students. You’re providing scope, being open to their ideas and also helping them stay focused and to take setbacks in stride,” she said. “They are so motivated and unafraid. It’s inspiring.”

A member of the ��ֱ�� faculty since 1996, McKnight has served the ��ֱ�� community in a number of departments including the Department of Civil, Environmental and Architectural Engineering; the Environmental Studies Program, INSTAAR; the Center for Water, Earth Science and Technology; Hydrologic Sciences Graduate Program; and the Mountain Research Station.

Her scholarly work explores ecological, biogeochemical and hydrologic processes in lakes, streams and watersheds, primarily in polar and mountain regions. These field studies analyze the dynamics of these systems and apply innovative measurement tools in harsh environments. She is a leader in measuring dissolved organic matter from the spectra of its fluorescence. Her top paper has been cited over 2,000 times. Her work has made her a leader in the National Science Foundation’s Long-Term Ecological Research Network, and she has served as a principal investigator in a number of projects since 1997.

McKnight’s work has transformed her field and has enhanced scientific understanding to the effects of climate change. She has been active in public outreach programs meant to translate science to the public, including her work on a children’s book series. An outstanding teacher and mentor of graduate students, she has served ��ֱ�� as a curriculum innovator in a wide variety of disciplines. Since 1996, McKnight has been the principal advisor to 24 PhD students. Not only has she led groundbreaking research, furthered public knowledge and served the ��ֱ�� community, she has prepared the next group of researchers to do the same.
