A Trend Analysis of Nitrate in the Southern Willamette Valley Groundwater Management Area (GWMA)

Creator:

Piscitelli, Cody M.

Abstract:

The shallow aquifer in Southern Willamette Valley (SWV) has high levels of nitrate, and we are exploring the time trends in nitrate, and the hydrologic and land management factors that contribute to this problem. Nitrogen (N) inputs to farmland from fertilizer is thought to be the primary source of nitrogen...

Effects of Secondary Salinization on Three Coastal Breeding Amphibians in Oregon: Taricha granulosa, Hyliola regilla, and Rana aurora

Creator:

Goddard, Amanda L.

Abstract:

Due to threats of secondary salinization caused by increased saltwater intrusion upstream associated with climate change, this thesis examines how salinity affects the development and oviposition site selection habits of three Oregon coastal breeding amphibians, the Roughskin Newt (Taricha granulosa), the Northern Red-legged Frog (Rana aurora) and the Pacific Treefrog...

Masters Thesis
The use of low cost “iButton” Temperature Logger Arrays to Generate High Spatial Resolution Tidal Inundation Regime Data

Creator:

Tully, Rebecca

Abstract:

Loss of wetlands within Oregon has led to strong interest in restoring wetlands that once existed. Restoration practitioners are currently using knowledge they have gained from many years of working with wetlands to design and carry out restoration projects. There is much variability between tidal wetlands within coastal Oregon and...
