Present GEK (Geomagnetic Electrokinetograph) theory is extended
to include internal waves of the lowest mode. The predicted
towed electrode GEK signal is determined to second-order for long-crested
internal waves in a finite but deep ocean. The analysis includes
the determination of GEK signatures for small amplitude and
finite amplitude interfacial...
The Columbia River plume region was investigated during the
period of 20 June to 3 July, 1968 by light scattering measurements
and standard hydrographic station observations. The Columbia
River plume was traced by the light scattering particles of the plume
water. The light scattering particles are estimated to be contained...
The effectiveness of the passive anti-roll tank system aboard
the R/V YAQUINA was determined. Measurements of ship roll,
effective waveslope and tank water transfer were analyzed using a
systems analysis technique. Time series of the inputs and outputs of
the ship/tank system and of the tank itself were processed using...
The distribution of particles in the Eastern Pacific Ocean was
investigated from 2 January to 14 February, l969, on the YALOC-69
cruise of Oregon State University. The size distributions were well
fitted by the two-parameter Weibull distribution function, with a
predominant number of them nearly exponential in distributional
The apparent optical properties of sea water are a set of measurables that describe the geometry of the submarine light field. These properties are related to the inherent optical properties—the volume attenuation coefficient and the volume scattering function—through the process of radiative transfer. A numerical approximation to the equation of...
The modulation transfer function (MTF) of a simple submarine viewing situation is computed as a function of range and sea-water properties. For the cases considered, we found that the MTF follows the simple exponential law, exp(-ω/ω₀), where ω is the spatial frequency in lines/deg and where ω₀ is a complicated...
A multi-disciplinary oceanographic cruise - YALOC '69 - was
carried out by staff of the Department of Oceanography, Oregon State
University aboard the R/V YAQUINA. This report describes the observational
YALOC '69 was motivated by a desire to study the geology, geophysics
and physical oceanography of the Panama...
The data contained in this report represents over 3000 individual scattering measurements taken in the equatorial Pacific in the vicinity of Johnston Island. The purpose of the measurements was to obtain data that would aid in the determination of a correct model for the mixing processes in the vicinity of...
