Monitoring the sources and fate of freshwater in the
East Greenland Current (EGC) is important, as this water
has the potential to suppress deep convection in the Nordic
and Labrador Seas if the outflow of freshwater from the
Arctic Ocean increases in response to climate change. Here,
hydrographic, oxygen isotope...
We investigate the freshwater composition of the shelf
and slope of the Arctic Ocean north of the New Siberian
Islands using geochemical tracer data (δ¹⁸O, Ba, and PO₄*)
collected following the extreme summer of 2007. We find
that the anomalous wind patterns that partly explained the sea
ice minimum at...
The feasibility of using lumber and plywood futures as a means of cross product hedging for stumpage is explored from the standpoint of the producer of forest products. A survey conducted in April, 1979 Indicates that this process has not been attempted in western Oregon. Historical price relationships between contract...
Juvenile Chinook Salmon (Oncorhynchus tshawytscha) leave the natal reach at different times and move downstream at different rates which can increase their productivity by allowing them to utilize habitats on different temporal scales and spreading risk of localized stochastic events. This life history diversity can also allow fish to adapt...
Ion therapy has long been investigated as a potential modality to improve cancer treatments beyond what is currently feasible with photon irradiations. Ions offer both a physical and biological advantage over photons. The physical advantages are well understood, ions deposit their maximum dose at defined penetration depths, allowing for minimal...
For 74 days during the spring and summer upwelling seasons of 1981 and 1982, in conjunction with the Coastal Ocean Dynamics Experiment, profiles of upper ocean currents were collected in the waters over the shelf and slope off northern California using a shipboard Doppler acoustic log. These measurements provide detailed...
The purpose of this study was to determine the significant
variables influencing the damage levels sustained by the residual
stand after skyline thinning of coniferous stands. Damage levels were
measured in ten study areas in western Oregon that had received their
first commercial thinning.
For this post-logging study, 38 units...
New materials with superior mechanical properties, such as increased strength and hardness, have been developed to allow for new and improved products. However, the mechanical properties that make these materials useful also makes them difficult to process using conventional methods. New machining processes need to be developed to generate products...
Fire regimes across the western United States have been altered due to past land management and changing land use. Mitigating increased risks of wildfire occurrence in landscapes such as central Oregon requires landscape level management from both governmental and private organizations. Non-industrial private forest (NIPF) owners manage a relatively small...
At the beginning of the nineteenth century most theorizing British naturalists supported a Biblical account of the distribution of life which was based upon the notion that life had been dispersed from the resting place of the ark. This implied a relatively even dispersion of life about the Earth, but...
