Sediment from rivers has both beneficial and detrimental effects on ecosystems and human activities around Puget Sound. We explain where the sediment comes from, how it is transported, and the nature of the data that we can use to understand it.
Project is designed to integrate studies from a number of researchers compiling data from terrestrial, marine, and freshwater ecosystems within south Florida. Links to publications, maps, posters, and data of studies.
New synoptic data from samples collected in the Arctic Ocean and insights into the patterns and extent of ocean acidification. This foundational geochemical information will help us to understand potential risks to Arctic resources.
Suspended-sediment concentration data were collected in San Francisco Bay during water year 2000 using optical backscatterance sensors and water samples. This report presents the data-collection methods, data, and calibration plots.
Lead page for detailed United States surface water information with links to real-time and historic streamflow data, suspended sediment data, USGS programs and facilities, publications, techniques, and featured news releases.
Nitrate from fertilizer is degraded by microbial action in the presence of solid minerals. This helps mitigate the effect of the nitrate, but begins to diminish the solid minerals needed. Will the process be sustainable in the long term?
