BioAntarctic ice sheet, both of which have exhibited significant mass loss over the past few decades. If the two ice sheets were to fully collapse, they could be responsible for up to 15m of global sea level rise (roughly equal parts from both). This sea level rise would not only pose serious problems for coastal settlements, but cause serious changes to ecosystems, and could profoundly alter the Earth’s ocean circulation.
Current estimates of the mass balance for ice sheets are based primarily on satellite data. This data has become more accurate and more available than ever before, since the 1990s. While estimates can be provided by satellite data, satellites are limited by virtue of the fact that they can only evaluate the surface of the ice shelf. Recent research has shown that a significant amount of the mass loss from the West Antarctic ice sheet is happening underwater, along grounding lines, where deep waters, warmed by global warming, enter the area underneath the ice shelf, and melt the shelves from the bottom. This not only results in mass loss directly, but increases calving of glaciers into the ocean, further accelerating their loss. This melting, below the surface of the ice shelves, cannot be estimated by satellites.
To get a better understanding of the impact of warmer deep waters on glacial retreat in Western Antarctica, we need to measure the melt more directly. Using highly precise measurements of salinity and isotopic composition of seawater in coastal regions of Western Antarctica, we can estimate the amount of glacial meltwater present in the oceanic adjacent to ice sheets. Gaining a greater understanding of the rates and locations of West Antarctic melting will be crucial to developing our understanding of future sea level rise, and other wider impacts. -
Natalie Herbert
Postdoctoral Scholar, Earth System Science
BioNATALIE HERBERT is a Postdoctoral Research Fellow in Behavioral Science in the Department of Earth Systems Science and at the Woods Institute for the Environment. Her research investigates decision-making in the face of environmental risk. She completed her Ph.D. in 2020 at the Annenberg School for Communication, where she researched health and science communication with a focus on communicating scientific uncertainty. In 2020, Natalie was a Christine Mirzayan Science and Technology Policy Graduate Fellow at the National Academies of Sciences, Engineering, and Medicine; she was the Rosenblith Fellow in Policy and Global Affairs and the InterAcademy Partnership.

Sara (Suki) Hoagland
Lecturer
BioSara (Suki) Hoagland is a Lecturer in the Earth Systems Program of the School of Earth, Energy and Environmental Sciences. She directs the internship program and team-teaches and mentors the undergraduate Capstone Project. She also teaches the Master's Seminar for the Earth Systems co-terms. In 2021 she launched the Sustainability in Athletics course with a team of scholar athletes. Recently she also taught the E-IPER first year Research and Design Seminar and team taught “Gender, Land Rights and Climate Change”. Previously, she was the first Executive Director of Stanford University's Interdisciplinary Graduate Program in Environment and Resources, (now E-IPER). She was a Senior Lecturer in that program and in the Stanford Woods Institute for the Environment. She designed and taught courses for E-IPER such as Case Studies in Environmental Problem Solving, Global Environmental Ethics, and Sustainable Development in Costa Rica, which included a field seminar there. She also served as the faculty advisor to the Stanford Farm and the Stanford chapter of Engineers for a Sustainable World.
From 1989 to 2000, Dr. Hoagland was Assistant Professor at the School of International Service at American University where she created the International Environment and Development Semester, which included three-week field practicums to East Africa and Central America. Dr. Hoagland was also the Director and Clinical Associate Professor for the Masters in Development Practice Program at the Josef Korbel School of International Studies at the University of Denver, where she also serves on the Board of Directors. She earned her BA in government from Wesleyan University, her MA in International Relations and Curriculum Development from the University of Denver, and her PhD in International Relations from American University.
She was a national silver medalist in pairs figure skating and earned 10 varsity letters at Wesleyan in field hockey, spring board diving and lacrosse. -
Randall Holmes
Ph.D. Student in Environment and Resources
BioAfter completing service in the U.S. Army, Randall transferred into Stanford University where he completed a BS in Civil and Environmental Engineering, Atmosphere and Energy track, as well as a master’s degree in Earth System Science. Randall is currently working toward his PhD in Stanford’s Emmett Interdisciplinary Program in Environment and Resources (E-IPER). Randall is considering research on the implementation of California’s Sustainable Groundwater Management Act, with specific interests in geochemical processes that afffect groundwater quality, water policy, and adaptive management with Prof. Scott Fendorf and Prof. Leon Szeptycki.
