Natural Variability of Nitrogen and Phosphorus in a Forested Headwater Stream System in the Oregon Coast Range

Creator:

Steadman, Casey L.

Abstract:

Our understanding of nitrogen (N) and phosphorus (P) variability in forested stream systems with minimal disturbance is confounded by the complex interactions of hydrologic and biogeochemical controls. In this thesis, our studies evaluate the variability of stream water N and P in a forested, headwater system in the Oregon Coast...

Biogeochemical signals of mountainous forested watersheds' response to disturbance

Creator:

Guerrero-Bolaño Francisco J.

Abstract:

Small mountainous watersheds are disproportionate sources of land-derived particulate organic matter (POM) to long-term sinks like lake bottoms and the ocean. As such, these ecosystems are an essential component of the global carbon cycle. The burial of POM in lacustrine and marine sediments contributes to the drawdown of atmospheric CO2...

Hydrological and biogeochemical dynamics of nitrate production and removal at the stream – ground water interface

Creator:

Zarnetske, Jay P.

Abstract:

The feedbacks between hydrology and biogeochemical cycling of nitrogen (N) are of critical importance to global bioavailable N budgets. Human activities are dramatically increasing the amount of bioavailable N in the biosphere, which is causing increasingly frequent and severe impacts on ecosystems and human welfare. Streams are important features in...
