1 | (1) Dissolved oxygen in Chesapeake Bay, (2) nitrate loading in the Potomac Basin, and (3) atmospheric nitric acid and wet deposition across the Eastern U.S. Three air and water models are linked together for cross-media modeling of the Chesapeake Bay. Atmospheric nitrogen deposition predicted by the atmospheric model (right) is the input load to the watershed model and the three- dimensional Bay model. The watershed model (lower left) delivers nitrate loads from each of the water basins to the three- dimensional Bay model (upper left). |
