How Earth’s Surface and Interior are Connected to Freshwater Availability

NASA’s Earth Science Research and Analysis (R&A) pro- gram’s Earth Surface and Interior (ESI) focus area sup- ports research and analysis of solid-Earth processes from crust to the core. This includes research on how the solid Earth interacts with the storage, movement, and trans- port of freshwater around the planet. Freshwater often leaves a signature on Earth’s surface or at depth that helps identify where it might be located. ESI uses NASA’s unique, space-based observations to better identify and understand interactions between hydrolog- ic and solid-Earth processes, which can help determine changes in freshwater stores.
