Hydrologic and Land Cover Effects on Sources and Fate of In-Stream Fluorescent Dissolved Organic Matter

Creator:

Lee, Baek Soo P.

Abstract:

Dissolved organic matter (DOM) is a critical component of the carbon cycle linking terrestrial and aquatic ecosystems. Although many factors influence DOM fluxes and quality in rivers, controls on DOM compositions in catchments of the western U.S. are poorly understood. UV and fluorescent spectroscopy is a simpler, faster, and less...

ABSTRACT OF THE DISSERTATION OF Baek Soo P. Lee for the degree of Doctor of Philosophy in Water
Hydro-biogeochemical coupling at the hillslope and catchment scale

Creator:

van Verseveld, Willem J.

Abstract:

The specific objectives of this dissertation are to determine subsurface flow behaviors across different antecedent wetness conditions from a top-down perspective and to mechanistically assess the hydrological controls on DOC and N transport at the hillslope and catchment scale. The study area is a small catchment where hillslopes issue directly...

Patterns of nitrogen fluxes in watersheds of the H.J. Andrews Experimental Forest, OR

Creator:

Vanderbilt, Kristin Lynn, 1967-

Abstract:

Seasonal and annual patterns of N fluxes and concentrations in streamwater in six conifer-dominated watersheds at the H.J. Andrews Experimental Forest, OR, were studied to gain insight into the factors that influence N retention in this ecosystem. Processes affecting N flux in streamwater differed between organic (DON) and inorganic (DIN;...
