The influence of grazing closing dates and form and amount of
nitrogen fertilizer on Gulf annual and Oregon annual ryegrass was
studied at locations in the Willamette Valley of Oregon.
Closing dates were established as mid-April, and May 1 together
with ungrazed plots for comparison. Fertility consisted of a single...
The utilization of historical data is suggested as an approach to
solving some of the difficulties involved in the estimating of activity
durations in critical path scheduling.
The historical data presented show the effects of various
weather conditions upon the performance of human labor and mechanical
equipment. When combined with...
Salinity, temperature, oxygen, phosphate, and nitrate observations were taken by Oregon State University of 15 hydrographic cruises in the Northeastern Pacific and one cruise in the Sea of Cortez during 1970. Alkalinity, pH and silicate were taken on special occasions.
Data were collected by Oregon State University personnel aboard the...
Direct interception of windblown cloud water by forests has been dubbed “occult deposition” because it represents a hydrological input that is hidden from rain gauges. Eddy correlation studies of this phenomenon have estimated cloud water fluxes to vegetation yet have lacked estimates of error bounds. This paper presents an evaluation...
This report presents data collected on six cruises made during the months May-October 1972 along the Oregon coast. Both complete data listings and sequential surface data contour charts are presented. The latter graphically display rapid changes in surface water characteristics on time scales as short as a few hours.
The...
The Moderate Resolution Imaging Spectroradiometer (MODIS) will add a significant new capability for investigating the 70% of the Earth's surface that is covered by oceans, in addition to contributing to the continuation of a decadal scale time series necessary for climate change assessment in the oceans. Sensor capabilities of particular...
