How much water is there? This side-by-side comparison illustrates Earth’s water, including total water, ocean water, frozen water, groundwater, and water in lakes & rivers.
Jeffrey Kwang
Jeffrey Kwang is a Physical Scientist for the USGS Water Resources Mission Area.
Jeffrey uses numerical modeling and remote sensing to study how landscapes evolve over a broad range of temporal and spatial scales. Prior to joining the USGS, Jeffrey researched the role of autogenic dynamics and rock heterogeneity in reorganizing river networks. Jeffrey also built high-resolution, region-scale models that predicted how agricultural practices have redistributed soil and soil organic carbon.
As a physical scientist at the USGS, Jeffrey is part of the Data Science Branch where he will help create interactive data visualizations to better communicate USGS science and numerical models to improve our predictions of sediment dynamics.
