Human activity has greatly changed nitrogen cycling and dynamics worldwide. In this unit, students explore large-scale anthropogenic changes to the nitrogen cycle by examining studies that document anthropogenic inputs of nitrogen globally, nitrogen saturation of temperate forests, the export of nitrogen from rivers to the ocean, and the ecology of Pfiesteria in the Chesapeake Bay.

| Description | The Digital Library for Earth System Education (DLESE) mission is to improve the quality, quantity, and efficiency of teaching and learning about the Earth System, by developing, managing, and providing access to high-quality educational resources and supporting services through a community-based, distributed digital library. Intended users include students, educators and citizens of all ages, in both formal and informal learning environments. The collection favors resources that convey linkages and connections; the general with the specific, theory with evidence, global with local, and that demonstrate the application of science to solving real world problems. This includes providing access to Earth data sets and imagery, and the tools and interfaces that enable their effective use. DLESE resources are community-contributed, by individuals, organizations, and formal collection efforts. |
