High-latitude Lake and River Dynamics Resources Hazards and Climate Change — High-latitude surface water dynamics are complex, fast-moving, and driven by snow, rainfall, ice, and permafrost. Modeling efforts to understand the mechanisms, and to predict variability due to natural processes and climate change, often lack basic hydraulic measurements, or the spatial and temporal coverage, or the information is poor. In particular, glacial lake dynamics are poorly constrained, yet critically important as they can induce positive feedbacks to the glacier (via rapid melting). The proposed research will use ICESat-2 laser altimetry data to investigate how glacial lake elevations and discharge vary as the lakes grow or shrink in area.
