Current observations over the continental shelf at locations off central Oregon and southern Washington
had the period from July 18 to September 18, 1972, in common. Low-frequency fluctuations (less than
one cycle per day) in the currents are compared by means of visual display, linear regression, and spectral
analysis. The...
This study includes an analytical solution to the wave-current
barrier interaction problem and large scale experiments to validate the
theory.
The boundary value problem is solved mathematically by characterizing
the flow field and barrier motion separately, then coupling
the relationships with the appropriate kinematic and dynamic boundary
conditions.
The flow...
Several series of measurements of the hydrography, currents,
and winds during the past ten years are used as a basis for an overview
of the physical oceanography and meteorology during the
upwelling season near Newport, Oregon. Data are described using
elementary statistics, progressive vector diagrams, coordinate system
independent spectra, and...
This thesis considered current approaches to describing landscape pattern,
identified scale issues associated with defining objects, and explored techniques to
reliably group elements based on land cover as represented by satellite imagery. It
was recognized that there is an important need to develop tools that can be applied
using remotely...
Detailed economic analyses of fisher performance are critical inputs in improving the management of fisheries. The paper provides guidelines about the economic methodologies and the data required to monitor and assess the performance of individual transferable quota fisheries. In particular, it describes the methods of evaluation that could be applied...
Using individual firm data from before and after the introduction of ITQs in the multi-species Nova Scotia mobile gear fishery, data envelopment analysis (DEA) is used to examine issues relating to capacity and capacity utilization. The paper examines how a change in the property rights regime can affect a multi-product...
The technique of freeze branding was developed by Dr. R. K. Farrell during the 1960’s as an alternative to fire branding domestic livestock. Today, freeze branding is internationally used for cattle and horse identification. In addition to many species of haired animals successfully freeze branded non-haired animals such as whales,...
Internally recording instruments were installed in the Drake Passage in January 1979 and recovered in January 1980. Additional instruments were installed at this time for the first experiment in the Pilot Ocean Monitoring Experiment. These are to be recovered in March of 1981. The array consisted of seventy current meters...
