Fruit tree fertilization is a standard grower practice intended to supplement soil-supplied nutrients. Both soil-applied fertilizers and nutrients stored within the tree are important. Tree reserves are the major source of nutrients for developing tissues before petal fall. Current-season growth and
yield are influenced by nutritional status, which in turn...
Industrial operations are becoming more mechanized and
automated. The increasing complexity of work affects the proportion
of physical to mental effort which workers spend in the performance
of their jobs. Traditional work measurement techniques which are
primarily designed to measure the individual's physical load have to
be complemented with other...
The following paper traces important decision processes
connected with initiating and constructing a coastal environmental
facility. There is a brief review of the early history and
summaries of the preliminary studies completed as of April 1986.
Particular focus is placed on the Oregon State University/Oregon
Coast Aquarium cooperative study. Finally,...
Differential investment in offspring has been reported for many mammals, often in the context of the Trivers–
Willard model of male-biased investment, but evidence of differential investment in pronghorns (Antilocapra
americana) is largely lacking. We assessed the causes and consequences of different birth masses of littermate
fawns in a pronghorn...
Streamflow response to rainfall is controlled by the net water budget and the routing of rainfall to stream channels. In rain-dominated forested regions, including the Oregon Coast Range, water budget aspects of forest hydrology are better quantified than water routing. As a result, most of the commonly used forest hydrology...
Hindcast and 21st century winds, simulated by General Circulation Models (GCMs), were used to drive global- and regional-scale spectral wind-wave generation models in the Pacific Ocean Basin to assess future wave conditions along the margins of the North American west coast and Hawaiian Islands. Three-hourly winds simulated by four separate...
The objective of this article is to present evidence for
the existence of seasonal variability in sea surface height
(SSH) anomaly in the Agulhas Retroflection region.
TOPEX/POSEIDON altimeter data are used to estimate
seasonal changes in the mesoscale SSH variability.
There is a seasonal oscillation of SSH variability characterized
by...
The relationship between iron and nitrate concentrations was examined off the coast of
Oregon during the upwelling season. Surface Fe and N (nitrate + nitrite) concentrations
measured underway by flow injection analysis ranged from <0.3 to 20 nmol L¯¹ and <0.1 to
30 mmol L¯¹, respectively. Total dissolvable Fe concentrations,...
For decades, the bio-duck sound has been recorded in the Southern Ocean,
but the animal producing it has remained a mystery. Heard mainly during
austral winter in the Southern Ocean, this ubiquitous sound has been
recorded in Antarctic waters and contemporaneously off the Australian
west coast. Here, we present conclusive...
