Manganese nodules are concretions which are widely distributed on
the bottom of marine waters as well as on the bottom of some lakes.
They vary in size, abundance, and to some extent composition, with
location. The nodules are of potential economic value because of the
nickel, copper, cobalt and manganese...
In 1970 a phytosociological reconnaissance consisting of 135 plots in the Subalpine Meadow Zone was made. These samples were sorted using an association table and several Alpine Zone and very early seral communities were set aside, An additional hundred plots taken by M. J. Hamann were
incorporated with these and...
The biomass and the composition of 15 stands of red alder (Alnus rubra Bong.) on river bottom sites in western Oregon was measured during August and early September, 1969. These stands ranged in age from two to 64 years. Biomass was found to vary from 134 k/ha (kilograms per hectare)...
The Oregon State University Extension Service Master Gardener Program is a voluntary educational
program designed to meet the community’s gardening needs. This publication provides an introduction to the program and the Master Gardener position.
Meat from big game animals (such as deer, antelope, elk, moose, and bear) is a nutritious choice for family meals. You'll enjoy eating it when it's good quality and well-prepared. For best flavor, it's important to handle game carcasses carefully and to butcher and store the meat correctly. This publication...
South Pacific intraplate volcanoes have been active since the Early Cretaceous. Their HIMU-EMI-EMII mantle sources can be traced back into the West Pacific Seamount Province (WPSP) using plate tectonic reconstructions, implying that these distinctive components are enduring features within the Earth's mantle for, at least, the last 120 Myr. These...
We simulated the erosion and accretion of a natural beach using a wave-resolving
eddy-diffusive model of water and suspended sediment motion in the bottom boundary
layer. Nonlinear advection was included in this one-dimensional (vertical profile) model
by assuming that waves propagated almost without change of form. Flows were forced by...
A potential vegetation classification system is presented for the Olympic National Forest. It is
based on a sample of 1046 Reconnaissance and 408 Intensive plots. The hierarchical classification
includes sixvegetation series and 64 plant associations. Diagnostickeys are presented to aid in the identification of series and associations. Descriptions are presented...
A classification of forest vegetation is presented for the Mt. Baker-snoqualmie Forest. It is based on the potential National vegetation and uses the plant association as the basic unit. The classification is based on 2464 sample plots distributed across the Forest from 1979 to 1990. Of these 1963 were in...
