Undergraduate Seminar Series- Hydrologic and Biogeochemical Controls of Atmospheric Nitrate Export in a Temperate Forest Watershed Time: 12:00p - 1:00p Location: COAD 313 Details:
How has acid rain impacted the N cycle in temperate forests? Why are stream nitrate concentrations in predominantly forested watersheds declining throughout the mid-Atlantic? Forests cover about 66% of the land area in the Chesapeake Bay watershed and provide clean water to downstream communities. Understanding the hydrology and biogeochemistry of these ecosystems will be instrumental in accomplishing Bay clean-up goals and ensuring the proper management/preservation of forests.
The emergence of long-term datasets and the development of new stable isotopic approaches now offer insights into the storage, transformation, and transport of N in forests. These findings will allow the development of mechanistic models that predict future forest responses to acid rain, disturbances, and climate change.
