Detailed analyses of snow crystal sequence and atmospheric
conditions were accomplished utilizing macrophotographic techniques
for obtaining the snow crystal record at Santiam Pass in the Oregon
Cascades on 19-20 January, 14-15 February, and 9-10 March, 1967.
The photographic equipment consisted of a 35 millimeter single lens
reflex camera, bellows, and...
The cattle industry in the Pacific Northwest is characterized by a large number of producers. Individual contributions to the market have little effect in moderating potential fluctuations in the prices received for the various classes of cattle. Price volatility is of constant concern to producers in planning future production, with...
Oregon's Willamette Valley sweet cherry growers have
developed a market for large, high quality, stem-on brining cherries.
The maturity indices pull force (PF), percent soluble solids (SS),
and weight (Wt) were chosen as being the most probable indicators of
maturity.
The rate of change of PF during the harvest period...
The atmospheric sodium daytime abundance was measured for
Corvallis, Oregon, using direct absorption of sunlight by atmospheric
sodium atoms, as observed with an optical waveguide spectrum analyzer.
The disadvantage of the spectrum analyzer is that it can't resolve the
sodium D-lines (Its resolving power is 0.5 nm, which is approximately...
A new experimental technique for the study of
atom-surface interactions is obtained by passing an atomic
beam containing high-Rydberg states through a fine mesh
target. The technique is demonstrated to be a sensitive
probe of the electric fields of adsorbed dipole layers in
transmission experiments in which a time-dependent beam...
This research consists of two related yet distinct
studies: an observational study of the surface character of
the penetration of marine air into the southern Willamette
Valley and a climatological study of the summertime air
masses of northwestern Oregon.
For the observational study, temperature and estimated
wind data were gathered...
