Overview


Dr. Sarah Cooley is an Assistant Professor of Planetary Health in the Division of Earth and Climate Sciences at the Nicholas School of the Environment at Duke. As PI of the Cryo-hydrO Observation Leaders (COOL) Lab at Duke, her research group investigates how climate change is affecting dynamic cryospheric and hydrologic processes in the Arctic and globally. Her research primarily uses satellite data to better understand fine-scale hydrologic change, but she has also conducted field multiple field campaigns in Alaska, Northern Canada, and Greenland. Her primary research focus areas include Northern surface water dynamics, Arctic coastal environmental change and its impact on communities, and global variability in surface water storage. She is also especially interested in how new technologies and big data approaches can revolutionize our ability to observe surface water from space, and she has worked extensively with both new NASA satellites (e.g. ICESat-2, SWOT) and startup commercial earth observation companies (e.g. Planet, ICEYE).

Sarah received her PhD in Earth, Environmental, and Planetary Sciences at Brown University in 2020. She has an MPhil in Polar Studies from the University of Cambridge where she was a Gates Cambridge Scholar and a BS in Geophysics from the University of North Carolina at Chapel Hill where she was a Morehead-Cain Scholar. Prior to starting at Duke, she was part of the inaugural cohort of Stanford Science Fellows at Stanford from 2020-2021 and was an Assistant Professor of Geography at the University of Oregon from 2021-2024. Sarah is especially passionate about all things Arctic, new satellite technologies, and making academia a more accessible, inclusive and healthy place for all.

Lakes Modify the Magnitude and Timing of the Northern Hemisphere Terrestrial Cryosphere Radiative Effect

Journal article Geophysical Research Letters · September 28, 2026 Vast areas of Earth's Northern Hemisphere are covered in lakes that form seasonal ice cover, yet their influence on the terrestrial Cryosphere Radiative Effect (CrREt) has not previously been quantified. Here we use 22 years of satellite data to ... Full text Cite

Satellites reveal contrasting seasonal buffering patterns of global lakes and reservoirs.

Journal article Science bulletin · July 2026 Seasonal redistribution of water storage by lakes and reservoirs is important for global water security, yet their distinct roles in regulating the global water cycle remain poorly quantified. In this work, we combine multisource satellite observations to ... Full text Cite

Remote sensing and the new global river science

Journal article Nature Water · June 1, 2026 Rivers impact the well-being of humans and the environment. As they increasingly face planetary-scale stressors, it is critically important to monitor and understand rivers at the global scale. As the only synoptic resource for global primary data on river ... Full text Cite
