These principles are relatively few and direct. For odor detection to occur, odorous compounds must be (a) formed,
(b) released to the atmosphere, and
(c) transported to the place of detection.
When you prevent or inhibit any of these steps, you reduce or remove the odor problem.
Cover crops planted in late summer are an inexpensive way to build better soil for gardening. Cover crops often are
called green manure crops. They are grains, grasses, or legumes that will grow during fall and winter and that you
can plow, spade, or till under in the spring.
Creeping buttercup (Ranunculus repens L.) probably is the most troublesome of several members of the buttercup family that are weeds in the Pacific Northwest. There are many native species of buttercup in the Pacific Northwest, but the weedy species are of European origin. It’s likely that they were introduced as...

In a study of cumulative effects of riparian disturbance by grazing on the trophic structure of high desert trout streams, watersheds with greater riparian canopy had higher standing crops of rainbow trout Oncorhynchus mykiss, lower daily maximum temperatures (range, 16-23°C compared with 26-31°C), and perennial flow. Watershed aspect influenced the...
Practical hydrostatic ocean models are often restricted to statically stable configurations by the use of a convective adjustment. A common way to do this is to assign an infinite boat conductivity to the water at a given level if the water column should become statically unstable. This is implemented in...
Data from the Hydrological and Atmospheric Pilot Experiment-Modélisation du Bilan Hydrigue (HAPEX-MOBILHY) field program and results from a one-dimensional model of the soil and atmospheric boundary layer are analyzed to study the daytime evolution of the relative humidity at the boundary layer top. This evolution is thought to control the...
The decay of a downward propagating near-inertial wave was observed over four days. During this short period, the energy of the near-inertial wave decreased by 70%. The shear layers produced by the wave were regions of enhanced turbulent dissipation rates. The authors estimate that 44% of the observed change in...

The effect of various wood characteristics on decomposition of metham sodium to methylisothiocyanate in sixteen North American and Southeast Asian hardwoods and softwoods was investigated. While marked differences were noted in the degree of decomposition among some species, the relationship between decomposition and lignin content, extractive levels, wood pH, or...
This report describes current meter measurements from an experiment to measure the deep western boundary current that carries dense water from the Antarctic to the Pacific Ocean. The field measurements were conducted as part of a joint two year experiment by Oregon State University, Texas A&M University, Woods Hole Oceanographic...
Although many people enjoy deer, these animals can be destructive to gardens, orchards, and landscaped areas. Deer damage to ornamental plants is associated with a variety of factors including increasing numbers of deer, human population shifts to rural and suburban areas, and landowners prohibiting deer hunting.
A simple statistic is derived for quantifying the potential for the aliasing of tidal errors in a given linear estimate of sea surface height constructed from altimeter data. The existence of M2 tidal constituent errors in Geosat data processed in the traditional way (i.e., with orbit errors removed using least...
This is an exhibit made by the Oregon Department of Fish and Wildlife before a meeting of the Oregon Fish and Wildlife Commission on October 19, 1994. It establishes rules to implement the Developmental Fisheries Program, and to govern harvests of covered species. Relevant Oregon Administrative Rules are given. Appendix...
High-temperature combustion oxidation measurements of nonvolatile dissolved organic carbon (DOC) have been determined for pore waters from sediments of Middle Valley, Ocean Drilling Program Leg 139, as well as for overlying and near-bottom seawater. The DOC values in the interstitial waters are generally greater than those in the overlying water...
Objectives: 1. Survey Oregon vineyards for the presence, identity and abundance of plant parasitic nematodes. 2. Document seasonal changes in abundance of species of important plant parasites in order to identify optimum times for sampling. 3. Evaluate the efficacy of Nemacur for reducing populations of plant parasitic nematodes.
"In the past 6 years research effort on the Marbled Murrelet (Brachyramphus marmoratus) has increased in response to an apparent dramatic decline in their numbers on the west coast south of British Columbia (Marshall, 1988, Carter and Erickson 1992, Nelson et al. 1992). Their recent listing as a federally threatened...

WTD Industries, Inc. and its subsidiaries ("WTD") employ approximately twelve hundred people in the business of manufacturing lumber and related activities.
In the mid 1980's WTD implemented a drug testing program to prevent users of illegal drugs from working for or continuing to work for the Company. The program was...

The easiest way to introduce phylloxera to a site is by infested plant material. If a grower can effectively remove any existing phylloxera on new plants, the rate of spread of phylloxera. in Oregon vineyards will be significantly decreased.
The objectives of this study are to determine methods for dipping...
The largest known Quaternary silicic lava body in the world is Cerro Chao in north Chile, a 14-km-long coulée with a volume of at least 26 km³. It is the largest of a group of several closely similar dacitic lavas erupted during a recent (< 100,000 year old) magmatic episode...
The endangered salmon crisis in the Pacific Northwest has researchers scouring the scientific and institutional literature for data, analysis and information. The accessible publications are the foundation for much of the current work and debate. But, older materials and institutionally-generated information containing unique data are harder to locate. To accurately...
The Oregon wine industry has gown in recent years to over 100 wineries. There is a strong need for enology Extension, technical assistance, and technology transfer of relevant research for commercial application. Enology Extension at OSU provides technical assistance to winery personnel including wine analysis, consultation on production problem, training...

Measuring the flow rate of water is the first step to good water management. All water right holders in the State of Oregon must be able to measure the flow rate of the water being diverted.
We harvested the first significant crop from the Woodhall clonal trials in 1993. Early results from clonal trials can be misleading but there are differences between clones that are already quite apparent in some cases. Many of the clone types could be readily identified this season by plant growth habit...
Riesling, Chardonnay, and Pinot noir wines from the 1992 vintage were fermented with several different commercial yeast strains. Differences were observed in fermentation rates, wine composition, and aroma and flavor. Preliminary results were reported on in the OSU Wine Grape Research Progress Reports, 1992-1993, Special Report 929, June 1993, OSU...
The divergence theorem as usually stated cannot be applied across a change of signature unless it is reexpressed to allow for a finite source term on the signature change surface. Consequently all conservation laws must also be ‘‘modified,’’ and therefore insistence on conservation of matter across such a surface cannot...
