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.
Vineyard acreage in Oregon continues to increase at a rapid pace. In the past two years alone 1600 acres of new vineyard land have been planted (Rowley et al., 2000). Much of this has been on phylloxera-resistant rootstocks. This practice is strongly encouraged, since it is the only practical way...

In 1988 the Tualatin River was designated 'water quality limited' by the Oregon Department of Environmental Quality. Three sources of pollution: urban point source, forestry non-point source and agricultural non-point source pollution were considered to contribute unacceptable levels of nutrients (phosphates and ammonium nitrates) to the river. Since a significant...

Crops were grown at the experimental farms using accepted cultural practices ( within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with precision plot sprayers. Unless otherwise indicated, preplant...
Magnetotelluric (MT) data from two sites 150 and
300 km southeast of San Francisco, California (geomagnetic
dipole latitude: 43 degrees, L approximately 1.9) show that
the usual MT assumption of spatially uniform external magnetic
fields is violated to a significant degree in the period
range 10-30 s. Inter-station transfer functions...
Stem sinuosity is thought to negatively impact wood quality, but no studies have characterized its vertical and radial effects on wood properties. Here we study wood quality along the entire stem in 25-year-old plantation grown Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) trees (32 trees total) that had been scored...
Continuous records of upper water column (0–150 m) temperature profiles, spectral distribution of downwelling irradiance, and phytoplankton solar-induced fluorescence at 25 m depth were obtained during the inaugural deployment of the Hawaii Air-sea Logging Experiment, A Long-term Oligotrophic Habitat Assessment (HALE ALOHA) mooring, near the Hawaii Ocean Time-series (HOT) Station...
The magnitude, seasonality, and duration of peak discharge responses to forest removal and regrowth and roads in 10 pairs of experimental basins in the western Cascade Range of Oregon are consistent with fundamental water balance and routing concepts in hydrology. Hypothesized effects of forestry treatments on evapotranspiration, cloud water interception,...
Alfalfa is capable of producing high yields of forage when grown on deep, well-drained soils. Good management practices are essential if optimum fertilizer responses are to be realized. These practices include use of recommended varieties, selection of adapted soils, weed control, disease and insect control, good seedbed preparation, proper inoculation...
Few studies have examined the own-price elasticity of Canadian softwood lumber supply or output-adjusted factor demand elasticities over the past two decades, despite the utility of these measures in understanding producer response to tariffs, to market shifts (such as the decline in U.S. public harvest), and to changes in domestic...

“International librarianship” is a term that embraces many different, though related, topics. These include international exchanges of librarians, cooperation between libraries and librarians in different countries, and the development of library services in Third World countries. Because the term covers so much territory, the literature on the subject is extensive....
Many people enjoy going to the beach, but few know how the tides work. People who earn their living on the sea have a special need to understand the tides; the rest of us need to understand the tides for different reasons. Knowing how tides work can help us avoid...
Subject reference librarians at OSU create subject guides to assist library patrons to locate pertinent sources on their own. These guides direct patrons to information in a variety of formats, including books, series, and journals, but often lack Internet resources. The original intent of the CAMEL Project was to set...
