This study was initiated in its original form in 1982 with the Yamhill Soil and Water Conservation District and the McMinnville Field Office of the USDA-Soil Conservation Service. The Soils Department, Oregon State University, was one of several cooperators, in part funded by The Wine Advisory Board.
In 1984 and...
A study of the oxidation of zircaloy in reactor
environments has been undertaken with the goal of
characterizing of the Thermal Gradient Test Facility
(TGTF) at Teledyne Wah Chang, Albany. A set of
oxidation models is presented from the literature, as
well as an extensive database of published oxidation
test...
Armillaria (Fr. ex. Fr.) is a parasite whose pathogenicity
and role in forest ecosystems often depends upon the
physiological condition of the tree. Therefore, I tested the
frequency and severity of Armillaria ostoyae (Romagn.) Herink
infection among Abies grandis (Dougl.) Lindl., Larix
occidentalis Nutt., Pinus contorta var. latifolia (Engelm.),
Pinus...
An energy balance analysis was performed on each of four
transplanted Douglas-fir [Pseudotsuga menziesii (Mirb.) Francol
seedlings growing on two cutover sites in southwestern Oregon. The
two sites were a clearcut and a partial-cut (shelterwood) side by
side, with a pair of seedlings used on each site. One seedling of...
Observations of sea surface temperature and wave height were made from a large, manned spar buoy (R/P FLIP) ~100 km off the coast of Baja California. Surface temperature was measured with a radiation thermometer which viewed a disc on the surface 12 cm in diameter. The instrument responded to frequencies...
The uptake of methylammonium (MA) by Chesapeake Bay phytoplankton was measured in short term experiments by using the 14C radioisotope. This uptake was inversely related to ambient NH4+ concentrations, and the specificity for uptake of both substrates was demonstrated by competitive inhibition. At stations with low ambient NH4+, MA uptake...
Paleomagnetic directions from the Eocene Tillamook Volcanic Series of the Oregon Coast Range
point 460 clockwise from the expected Eocene field direction. Potassium argon dating of six dikes and
flows from this formation yields a mean age of 44.3 ± 0.6 m.y. These results establish that the Oregon
coastal block...
