Various methods of presenting and mathematically describing particle
size distribution are explained and evaluated. The hyperbolic
distribution is found to be the most practical but the more complex
characteristic vector analysis is the most sensitive to changes in
the shape of the particle size distributions.
Particle size distribution, nutrient concentrations,...
This report comprises one part of a final report to the Alumax Pacific Aluminwn Corporation on the "Physical, Chemical and Biological Studies of Youngs Bay". The data reported herein are the product of the geochemical baseline section of the project.
The primary objectives of the geochemical study were:
1) to...
The analytical method employed for the Total Organic Carbon (TOC)
project in the Geochemical Ocean Sections Study (GEOSECS) is described
in detail. The method generally follows that of Menzel and Vaccaro as
modified by several subsequent workers including the GEOSECS group at
Oregon State University which carried out the TOC...
Spectral beam attenuation coefficients, spectral volume scattering
function meaurements at 45°, 90°, and 130° particle size distributions
and chlorophyll a and phaeophytin pigment concentrations were measured during
May and September, 1977 in Monterey Bay, California. This data is examined
and statistical interrelationships between the parameters measured are
explored.
It was...
This report presents progress accomplished during the 20-month period from 1 July 1972 through 31 March 1974 as part of the program "Ecological Studies of Radioactivity in the Columbia River Estuary and Adjacent Pacific Ocean". This program is a continuing study supported by the Division of Biomedical and Environmental Research...
Bayocean sand spit lies along the northern Oregon coast
approximately 70 miles south of the Columbia River. Work was
begun on the construction of a large recreational resort on the spit
in the early 1900's. At the outset, the resort appeared to have a
promising future. However, a three-year delay...
This report represents the progress in "Ecological and Radioecological
Studies in the Columbia River Estuary and Adjacent Pacific
Ocean" for the period 1 April 1975 through 31 March 1976. This research
has been supported with funds from the Division of Biomedical and
Environmental Research, U.S. Energy Research and Development Administration...
A real-time data acquisition/central system has been developed for
environmental monitoring and research. The basic elements of the system
are a large instrumented spar buoy, a computer which controls data acquisition
through a telemetry link and simultaneously files and analyzes the data,
and the investigator who prescribes appropriate sets of...
Observations of wind speed and direction, air and sea temperature, and solar radiation were obtained from an array of buoys in JASIN. The observations were analyzed to show spatial and temporal variability. Spectra of wind speed and air and sea temperature were computed to illustrate the distribution of variance over...
Over the continental shelf at 15°S off Peru, sigma-t is a well-defined
function of temperature (Figure 1) and hence temperature alone may be used
to monitor the changes in stratification, to test the thermal wind equation,
and to monitor the hydrographic response to wind events. In this report we
present...
