The lab celebrates Erin Rooney's (very first) first-author publication in Geoderma, "Soil pore network response to freeze-thaw cycles in permafrost aggregates." Congratulations to Erin and Rebecca!
Erin Rooney was awarded an NSF Office of Polar Programs Postdoctoral Research Fellowship for 2022-2024! Following Spring 2022 graduation, Erin will be studying freeze-thaw cycles in Arctic permafrost soils with Dr. Beth Herndon and the Phosphorus-Iron team at the University of Tennessee-Knoxville.
Congratulations to Julia Fleiner on a successful MS thesis defense! Julia persevered during the pandemic, adapting to difficult research conditions in order to conduct density fractionations and soil analyses. Julia's research coupled imaging and chemical analyses to identify carbon partitioning across lithologies in Southeast Alaska. This fall, Julia will be starting her PhD in Soil Science at the North Carolina State studying saltwater intrusion. Congratulations Julia!
Congratulations to Jennifer Fedenko on a successful MS thesis defense! After machete-ing her way through the wild foliage of Southeastern Alaska, Jennifer compiled an awesome thesis focusing on soil development and soil organic carbon stocks across differing lithologies. Jennifer will be joining the USDA-NRCS as a soil scientist in Fall 2021 in Pasco, Washington. Congratulations Jennifer!
The Lybrand Lab is moving to UC Davis! Rebecca started a new
faculty position with Land, Air & Water Resources with UC Davis
on November 1st. Rebecca has transitioned into a Courtesy Faculty
appointment with OSU and continues to mentor the excellent
team of students finishing in her program at Oregon State!
Rebecca was interviewed about her and Jennifer's most recent publication about interactions between ground-nesting bees and soil! Read the news article here: https://www.soils.org/news/science-news/studying-interactions-between-ground-nesting-bees-and-soils
Congratulations to Julia Fleiner who received a Graduate Student Research Grant from the Geological Society of America for her research of carbon in the soils of the coastal perhumid temperate rainforest in Juneau, Alaska.
Welcome to Julia Fleiner! Julia finished a double major BA in Environmental Earth Science and Biology at Miami University and will be working on her MS in soil science. Congratulations, Julia!
Erin began her OSU-PNNL Distinguished Graduate Fellowship with Dr. Vanessa Bailey at Pacific Northwest National Laboratory. Erin will be studying impacts of freeze-thaw cycles on spatial distribution of stable isotopes in permafrost soils.
This fall, many of us presented at conferences including the ASA, CSSA, SSSA International Annual Meeting in Texas and AGU in San Francisco. Jennifer presented her poster of preliminary lab data from her field work in Juneau this past summer. Ben Pierce presented a poster of his undergraduate research from Juneau.
Jennifer traveled to Juneau, Alaska this summer to complete field work for her research. Potential sample sites in three different lithologies of the Tongass National Forest were surveyed. To access her sites, Jennifer and a fearless crew of scientists macheted through the omnipresent Oplopanax horridus (known all to well by many of us as Devil’s Club) and climbed up steep (up to 70% slopes) game trails in the forests. Once a site was found, a soil pit was dug, the pedon described and sampled. Lab analyses of over 100 samples are now in progress with a focus on carbon, nitrogen and particle size analysis, pH, bulk density, XRF, and XRD.
The Coastal Rainforest Margins Network published an article about Jennifer's summer field work:
Rebecca and Jennifer traveled to Juneau, Alaska to attend the 3rd annual Coastal Rainforest Margins Research Network workshop. This year’s subject was “Transformation and Transport of Elements and Compounds from Terrestrial to Aquatic Systems”. Our field day included excursions to a poor fen, bog, peatlands, Holocene terraces, and a dig for ancient clams deposited several thousand years ago. The remainder of the workshop included lectures and research planning of new and exciting research by scientists across research disciplines and international borders. https://coastalmarginsnetwork.org/
Congratulations to Jennifer who was awarded a Graduate Student Research Grant from the Geological Society of America and was as selected as a 2019 NSF CZO SAVI summer intern for her research!
Erin traveled to Svalbard, Norway to attend the Permafrost and Periglacial Environments course. Erin spent over six weeks in Longyearbyen learning about Arctic permafrost from a variety of Arctic researchers. Subjects covered included permafrost dynamics, talus slopes, frost heave, rock glaciers, and ice-wedge polygons.
Link to paper published in late March 2019 by Rebecca, Erin and Jennifer on developing a method to assess nano-scale weathering in minerals utilizing helium ion microscopy and scanning electron microscopy:
Erin traveled to Italy and Switzerland to study high Alpine permafrost with Dr. Michele Freppaz, Dr. Christian Hauck, and Dr. Christin Hilbich. Study areas included pedology, geomorphology, and geophysics. Funding was awarded through the CZO SAVI scholarship.
Erin and Rebecca attended the Arctic Soil Field Tour. The course was an intensive ten day exploration of Alaskan soil features throughout the permafrost gradient of southern to northern Alaska. After the course, Erin and Rebecca conducted fieldwork in the Fairbanks area within a permafrost-affected catena.
Jennifer traveled to southeast Alaska with where she collected preliminary samples with Dr. Dave D'Amore for her M.S. project on carbon, and differing lithologies, along soil catenas of the rainforest. You can read about her travels to Juneau in OSSS's (Oregon Society of Soil Scientists) summer newsletter by clicking here.
Congratulations to Jennifer Fedenko! This fall she will begin her M.S. degree at OSU! Jennifer will be working in Southeast Alaska with Dr. David D'Amore, looking at soil catenas of the perhumid subzone of the coastal temperate rainforest.
Dr. Paul McDaniel, a professor at the University of Idaho, led a soils tour in northern Idaho in September 2017. Members of Oregon State University’s Landscape Pedology Lab joined Paul and his students to admire Andisols, Spodosols, and Histosols across northern Idaho. One highlight of the trip was stopping near the Idaho-Montana border to visit the site where a glacial ice dam once impounded Glacial Lake Missoula. It was an incredible sight and offered an exciting perspective on the intensity of the Missoula floods!
Below is a short video of our adventure:
Rebecca recently returned from a trip to Southeast Alaska where she is partnering with Dr. David D'Amore and the Pacific Northwest Research Station on a project titled, "Critical Zone Science along the Pacific Coastal Margin." Rebecca joined David on site selection and soil sampling field outings in the Heen Latinee Experimental Forest located outside of Juneau, Alaska.
Did you know that one of the many benefits that soil provides to our society is promoting native bee activity by providing suitable ground for nesting activities? Jennifer Fedenko, a member of the Lybrand Lab, has been recruited to work on an "Agriculture, Bees, and Soil" project where she is studying native bee activity, documenting nests, collecting soil samples, and performing lab analyses. Jennifer is working under the leadership of Dr. Lybrand and Dr. Rao, a field crop entomologist, with funding from the Agricultural Research Foundation.
The Lybrand Lab will be conducting research on cross-scale mineral weathering processes in partnership with the Environmental Molecular Sciences Laboratory at the Pacific Northwest National Lab. This work is part of Dr. Lybrand's cross-CZO research initiative to better understand the drivers of mineral weathering in humid to semiarid landscapes and has been funded through EMSL's Science Theme user proposal opportunity.
