The causes of turbidity in impounded and released reservoir
water are studied. Seven Willamette Basin reservoirs are compared
to isolate watershed and reservoir characteristics which produce variations
in turbidity. Of the seven, Hills Creek Reservoir is examined
in detail. Particular features of the basin and impoundment are
studied to isolate...
The influence of planting patterns and plant spacings on grain
yield in field corn (Zea mays) was studied at the Oregon State University
Botany and Plant Pathology Field Laboratory near Corvallis,
Oregon in 1969. Plant characteristics and yield components studied
included plant height, ear height, number of ears, ear weight...

Sphagnum fens on the coast of Oregon are unique globally and contain a variety of rare plants and animals found nowhere else in the landscape. Evidence indicates that in the absence of disturbance, many open fens have converted to tall shrub and forest stands...
The Columbia River Gillnetter is the pilot of the Lower Columbia River commercial fishing industry, keeping fishermen and the public in touch with today's important issues.
In salmon-rich, northern coastal environments brown bears can occur at high densities and exert wide-ranging effects on ecosystem processes. Bear consumption of seasonally available fruit may provide important seed dispersal services to plants, and by extension, influence the ecology of seed consumers such as small mammals. In this study, we...
Femtosecond stimulated Raman spectroscopy (FSRS) is a powerful ultrafast technique which can track photoinduced excited state structural events on femtosecond (fs) to picosecond (ps) timescales. In addition to high temporal and spectral resolutions, FSRS provides a broad spectral window from ca. 100—2000 cm-1 for detection, enabling the direct mapping of...
Fossil foraminifers from the Coaledo and Bastendorff Formations
near Coos Bay in southwestern Oregon were studied in an attempt
to determine the age and environment of deposition. Fresh unweathered
samples were collected from sea cliffs between Cape
Arago and Charleston, Oregon.
A large late Eocene delta is preserved in the...

Spontaneous quasicrystal (QC) formation has not been observed in pure metals either in computation or in experiments (excluding epitaxial growth of thin atomic layers on a QC template). In this thesis work, dodecagonal QC (DDQC) grains are first discovered to spontaneously form during thermal devitrification of pure tantalum (Ta) metallic...
Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...
