Biology and management of glyphosate-resistant creeping bentgrass

Creator:: Hancock, Daniel M.
Abstract:: A two year study was conducted at two locations to determine the effect of three perennial ryegrass (Lolium perenne L.) row spacings on creeping bentgrass (Agrostis stolonfera L.) biomass and seed production. At Location 1 in 2002, the creeping bentgrass biomass within the 7.62 cm row spacing was less than...

Urban residents and non-point source pollution : an examination of practices, influences, and values in the Tualatin watershed

Creator:: Nielson, Lisa M.
Abstract:: In July of 2001, the Environmental Protection Agency (EPA) activated the Total Maximum Daily Load (TMDLs) provisions of the Clean Water Act. As the first river in Oregon to implement TMDL regulations, people and agencies in the Tualatin basin face many challenges. Non-point source pollution affects water quality in the...

Cape Scene & the path to a conscientious tourism product

Creator:: Sykes, Kimberly M.
Abstract:: Many countries around the world are looking to tourism as a sustainable solution for economic development and many individuals seek business opportunities in the tourism industry. Researchers in the field of anthropology and other disciplines alike have recorded findings of the environmental, economic and cultural impacts of tourism development that...

Error spectrum for the global M₂ ocean tide

Creator:: Ray, Richard D., Eanes, R. J., Egbert, Gary D., and Pavlis, N. K.
Abstract:: The most accurate determinations of the global ocean tides are currently based on altimeter measurements made by the Topex/Poseidon satellite. The error spectrum corresponding to the M₂ tidal solution is here estimated, primarily by inverse methods and secondarily by simple differencing in flatter than tidal signal spectrum, and it exceeds...

The M₂ Internal Tide off Oregon: Inferences from Data Assimilation

Creator:: Kurapov, Alexander L., Egbert, Gary D., Allen, J. S., Miller, Robert N., Erofeeva, Svetlana Y., and Kosro, P. M.
Abstract:: A linearized baroclinic, spectral-in-time tidal inverse model has been developed for assimilation of surface currents from coast-based high-frequency (HF) radars. Representer functions obtained as a part of the generalized inverse solution show that for superinertial flows information from the surface velocity measurements propagates to depth along wave characteristics, allowing internal...

Tidal wetland prioritization for the Smith River Watershed: Umpqua River Estuary of Oregon

Creator:: Brophy, Laura S. and So, Khemarith
Abstract:: This prioritization is designed to provide strategic focus for tidal wetland conservation and restoration actions undertaken in partnership with willing landowners. The study highlights land areas in the Smith River Watershed (within the Umpqua River estuary) where tidal wetland restoration or conservation action may offer the biggest ecological “bang for...

Bycatch in the ocean shrimp Pandalus jordani fishery

Creator:: Hoover Krutzikowsky, Vicki
Abstract:: The purpose of this research was to explore the impact of finfish bycatch on the ocean shrimp Pandalus jordani fishery using two methods. One method looked at the breakage of the shrimp by finfish bycatch in the nets. The other looked at the impact of bycatch on fishing decisions. At-sea...

A modeling study of katabatic flows

Creator:: Smith, Craig M.
Abstract:: A modeling study is undertaken to better understand the physics of katabatic flows. This study is divided into three topics; a comparison between a large eddy simulation (LES) and a mesoscale model of katabatic flows, a sensitivity study of katabatic flows to various physical parameters, and an investigation into the...

Geological and geochemical contraints on the isotopic composition of interstitial waters from the Hydrate Ridge region, Cascadia Continental margin

Creator:: Tomaru, A. M., Matsumoto, R., Torres, Marta E., and Borowski, Walter S.
Abstract:: The isotopic compositions of interstitial waters collected from Hydrate Ridge during Ocean Drilling Program Leg 204 were measured to evaluate the fluid evolution of this accretionary prism. At shallow depths, the dissolved Cl- concentrations and δD and δ¹⁸O values of the interstitial water reflect changes in the salinity and the...

Investigation of microorganisms and DNA from subsuface thermal water and rock from the east flank of Juan de Fuca Ridge

Creator:: Fisk, Martin R., Thorseth, Ingunn H., Urbach, Ena, and Giovannoni, Stephen J.
Abstract:: During Leg 168 of the Ocean Drilling Program, basalts were recovered by drilling and subsurface water was collected with a water sampling tool at Hole 1026B on the east flank of Juan de Fuca Ridge. Microorganisms were found in both types of samples. The microorganisms in the basalt appear to...
