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...
It is shown that the complex index of refraction of a given particle-size distribution may be calculated if the particle extinction coefficient and the particle absorption coefficient are known. If the particles are assumed to be nonabsorbing, a real index of refraction may be calculated from the ratio of light...
The distribution of suspended matter in the Panama basin was determined by means of
light scattering and Coulter counter measurements on water samples collected at 50 hydrographic
stations. The observed distribution indicates three probable sources of suspended
matter: (1) the surface waters throughout the basin; (2) erosion and runoff from...
Observations made during October and December 1971 on the Yaloc 71 Cruise of Oregon State University indicate the presence of the Cromwell Current on the east side of the Galapagos Islands. Light scattering, particle size distribution, nutrients, and standard hydrographic parameters were measured in water samples collected at 154 stations....

A method is described for determining the index of refraction distribution and the particle size distribution
of suspended particles. The distribution s are obtained by breaking down an observed volume
scattering function into its contributing components. The component scattering functions are calculated
using Mie theory. The component functions include all...
Suspended matter in Astoria canyon was monitored by means of an in situ nephelometer and by means of light-scattering and particle concentration measurements performed aboard ship on water samples. Nephelometer profiles obtained along the axis of the canyon in February and April 1973 indicate that the canyon is divided into...
Particle size distributions (8-105-μm diameter), chlorophyll a, and particulate carbon
were measured off the Oregon coast during July 1973. The particle counts were transformed
to volume concentration and then subjected to characteristic vector analysis.
Ninety-two percent of the variance was accounted for by linear combinations of the first
two characteristic...
One hundred and seventy pairs of temperature and light transmission profiles were obtained by simultaneous conductivity-temperature-depth (CTD) and light transmissometer casts in three cruises on the R/V Yaquina over the continental shelf off Oregon. These were analyzed for bottom nepheloid layers (BNL) and bottom mixed layers layers (BML). Supplementing these...
