Sediments at the southern summit of Hydrate Ridge display two distinct modes of gas hydrate occurrence. The dominant mode is associated with active venting of gas exsolved from the accretionary prism and leads to high concentrations (15%–40% of pore space) of gas hydrate in seafloor or near-surface sediments at and...
New grading standards for hay have been proposed by the American
Forage and Grassland Council and the Federal Grain Inspection Service.
This publication traces the development of these standards, describes new
terminology, and reports on research conducted at Oregon State University
to evaluate these new standards.
Alfalfa hay samples obtained...
Wheat is the primary field crop in Oregon. Selection of time of sale is one of the most important marketing problems facing grain producers. The objectives of the study deal with economic considerations involved in a wheat producer's marketing process including factors motivating the time of sale, price analysis, availability...
The characteristics and interactions of the riparian
stand, large woody debris (LWD), and channel morphology
were examined on five undisturbed, low gradient streams in
southeast Alaska. One first-, two second-, one third-,
and one fourth-order streams were studied. Stream
morphology variables were measured systematically at fixed
intervals of three to...
Several types of channel morphology measurement parameters used to
characterize fish habitat of small streams are refined, developed and evaluated in terms
of their accuracy, precision, and sensitivity to disturbance. Data for 74 stream reaches
in Oregon and Alaska are used in analysis. Over half the reaches are from a...
This paper analyses the factors explaining productivity and efficiency differences across salmon aquaculture farms, with an emphasis on agglomeration externalities. We specify a stochastic frontier production model with agglomeration indexes included in both the frontier production function and the technical inefficiency model. The frontier model is estimated on a rich...
