U.S. federal water-related R&D by agency, 1964-2010 (FY 2011 dollars)

摘要

This graph tracks water-related R&D spending at the U.S. Geological Survey, the National Science Foundation, the Environmental Protection Agency, and the National Oceanic and Atmosphere Administration. It does not include the relatively minor investments of several other agencies, such as the National Aeronautics and Space Administration's spending on remote water sensing. Complicating matters, several agencies we examined have restructured budget-tracking methods over the years, making it difficult to make accurate comparisons across decades.
