Thesis | Glacial Erosion in Arctic and Atlantic Canada Determined by Terrestrial in situ Cosmogenic Nuclides and Ice Sheet Modeling |
Jane Kathryn Willenbring (born August 2, 1977) is an American geomorphologist and professor at Stanford University. She is best known for using cosmogenic nuclides to investigate landscape changes and dynamics. [1] She has won multiple awards including the Antarctica Service Medal [2] and the National Science Foundation CAREER Award. [3]
Willenbring was born on August 2, 1977, to Roys E. and Elaine K. Willenbring. She grew up in Mandan, North Dakota. She developed a curiosity about the landscape and began creating her own small experiments. [4]
Willenbring completed her Bachelor of Science in geosciences/soil science in 1999 at North Dakota State University, where she was McNair Scholar. Willenbring was a graduate student in Earth science at Boston University, where she graduated in 2002. In 2006, Willenbring completed her Ph.D. in Earth Sciences at Dalhousie University [5] in Nova Scotia, Canada. Her thesis investigated glacial erosion in the Arctic and Atlantic Canada using cosmogenic nuclides. [6] Following her Ph.D. work, the National Center for Earth Surface Dynamics awarded Willenbring a Synthesis Postdoctoral Fellowship at the University of Minnesota. Two years later, in 2008, Willenbring was awarded an Alexander von Humboldt Postdoctoral Fellowship at Leibniz University Hannover and GFZ-Potsdam in Germany where she worked until 2010. [7]
Following her postdoctoral work in 2010, Willenbring joined the University of Pennsylvania's faculty as an assistant professor in the School of Arts and Sciences' Department of Earth and Environmental Sciences until 2016. [8] Willenbring then became an associate professor at Scripps Institution of Oceanography at UC San Diego where she was also the director of the Scripps Cosmogenic Isotope Laboratory (SCI-Lab). [8] In 2020, Willenbring became an associate professor at Stanford University. [9]
Willenbring's work focuses on how the Earth's surface changes in response to a variety of forces including tectonics, climate, and living organisms. She utilizes high-resolution topographic data, field observations, landscape evolution models, ice sheet models, and geochemical techniques, specifically cosmogenic nuclides, to study the Earth's surface. [1] [10] Willenbring is at the forefront of her field [11] and has developed the use of beryllium-9 and cosmogenic beryllium-10 to trace erosion, [12] weathering, [13] and meltwater pulses [14] in order to study and track the changes in Earth's surface. [1]
Willenbring has used some of her cosmogenic nuclide techniques in her research in Antarctica and Puerto Rico. [1] She has dated meltwater pulses in Antarctica during warming periods using the ratio of beryllium-10 to beryllium-9. [1] [14] Willenbring is also a current investigator at the Luquillo Critical Zone Observatory in Puerto Rico [15] where she and her colleagues use beryllium-10, as well as other cosmogenic nuclides, to investigate how Puerto Rico's landscape has affected its biodiversity. [1] [10] Their research has uncovered that nutrient-rich dust travels to Puerto Rico from the Sahara Desert which helps trees to grow in Puerto-Rico's nutrient-poor soil. [1]
In 2016, Willenbring received a National Science Foundation CAREER grant which she will use to study how beryllium isotopes can be used to track land-based sediment. Some of the funds will also be used to continue her citizen science project, "Soil Kitchen". [3]
In addition to Antarctica and Puerto Rico, Willenbring has also conducted research in Canada, and the South Fork Eel River in Northern California. [10]
Willenbring has also received significant funding from the National Science Foundation [3] and the University of Pennsylvania. [19]
Willenbring has been credited with bringing the #MeToo and #TimesUp movement to science. [20] In 2016, she filed a Title IX complaint of sexual harassment against her graduate school adviser, Dr. David R. Marchant. Her story received extensive media attention because the story was released the day after the New York Times story of Harvey Weinstein's alleged[ clarification needed ] sexual assault and harassment that helped spark the viral #MeToo movement. [21] The case led to an investigation by the science committee of the US House of Representatives, as well as the renaming of an Antarctic glacier previously named after Marchant and his firing from Boston University. [22] [23] [24] Her case also contributed to the creation of new policies within professional societies around fellowship and medal award procedures, and to new US National Science Foundation funding policies. [22] [25] She is featured prominently in the 2020 PBS Nova documentary Picture a Scientist , discussing her experiences and opinions on the matter. [26] [27]
Willenbring continues to raise awareness about sexual harassment in academia. She has advocated for the National Science Foundation to promote safer working conditions at all of their funded research sites. [28] She also brought the Growing Up Science lecture series to the Scripps Institution of Oceanography; [10] The series is intended for scientists to share stories on the challenges they faced while throughout their career path. [29] Willenbring was awarded the UC San Diego Equal Opportunity/Affirmative Action and Diversity Award in 2018 for her efforts. [30]
Willenbring also developed the citizen science project "Soil Kitchen". [1] The program allows people to bring in their soils to be tested for heavy metal contamination and soil nutrients. The project is designed to educate the public and clean up urban contamination. [31] [32]
Willenbring is married to Neil A. Malhotra. They have one child together, who was born in 2012. [33]

Beryllium-10 (10Be) is a radioactive isotope of beryllium. It is formed in the Earth's atmosphere mainly by cosmic ray spallation of nitrogen and oxygen. Beryllium-10 has a half-life of 1.39 × 106 years, and decays by beta decay to stable boron-10 with a maximum energy of 556.2 keV. It decays through the reaction 10Be→10B + e−. Light elements in the atmosphere react with high energy galactic cosmic ray particles. The spallation of the reaction products is the source of 10Be (t, u particles like n or p):
Roger Randall Dougan Revelle was a scientist and scholar who was instrumental in the formative years of the University of California, San Diego and was among the early scientists to study anthropogenic global warming, as well as the movement of Earth's tectonic plates. UC San Diego's first college is named Revelle College in his honor.
Beryllium (4Be) has 11 known isotopes and 3 known isomers, but only one of these isotopes is stable and a primordial nuclide. As such, beryllium is considered a monoisotopic element. It is also a mononuclidic element, because its other isotopes have such short half-lives that none are primordial and their abundance is very low. Beryllium is unique as being the only monoisotopic element with both an even number of protons and an odd number of neutrons. There are 25 other monoisotopic elements but all have odd atomic numbers, and even numbers of neutrons.
Project Mohole was an attempt in the early 1960s to drill through the Earth's crust to obtain samples of the Mohorovičić discontinuity, or Moho, the boundary between the Earth's crust and mantle. The project was intended to provide an earth science complement to the high-profile Space Race. While such a project was not feasible on land, drilling in the open ocean was more feasible, because the mantle lies much closer to the sea floor.
Cosmogenic nuclides are rare nuclides (isotopes) created when a high-energy cosmic ray interacts with the nucleus of an in situ Solar System atom, causing nucleons to be expelled from the atom. These nuclides are produced within Earth materials such as rocks or soil, in Earth's atmosphere, and in extraterrestrial items such as meteoroids. By measuring cosmogenic nuclides, scientists are able to gain insight into a range of geological and astronomical processes. There are both radioactive and stable cosmogenic nuclides. Some of these radionuclides are tritium, carbon-14 and phosphorus-32.

Surface exposure dating is a collection of geochronological techniques for estimating the length of time that a rock has been exposed at or near Earth's surface. Surface exposure dating is used to date glacial advances and retreats, erosion history, lava flows, meteorite impacts, rock slides, fault scarps, cave development, and other geological events. It is most useful for rocks which have been exposed for between 103 and 106 years.
