Abstract:: A method for predicting oceanic productivity from remotely sensed diffuse attenuation (488 nm) and surface chlorophyll concentration is presented. The method uses a climatological approach which consists of applying a set of regressions for each region and season to yield the depth of the chlorophyll maximum, the exponential slope of...

Abstract:: A fundamental relationship of inherent optical properties (IOP) is that the beam attenuation coefficient is the sum of the volume absorption and scattering coefficients (c = a + b). A relative calibration of a set of instruments can be provided using this IOP closure equation. Measurement of the true beam...

Creator:: Zaneveld, J. Ronald and Kitchen, James C.
Abstract:: Optical oceanography models of attenuation and scattering properties often contain simple spectral relationships. Electromagnetic theory, however, predicts fluctuations in the spectra of the attenuation coefficients and scattering properties of substances at wavelengths near an absorption peak. We have modeled these effects for phytoplankton using homogeneous, two‐layered, and three‐layered sphere models...

Abstract:: A simple heat budget model for a radiation-dominated mixed layer of constant depth is presented. In this model the influence of the vertical irradiance (heat flux) profile is examined by means of the Jerlov [1976] optical water type classification. It is shown that the vertical irradiance profile is important in...

Abstract:: The reflectance of the bottom is of importance when interpreting optical data in shallow water. Closure studies of radiative transfer, interpretation of laser line scanner data, lidar, and remote sensing in shallow waters require understanding of the bottom reflectance. In the Coastal Benthic Optical Properties experiment (CoBOP), extensive measurements of...

Creator:: Boss, Emmanuel and Zaneveld, J. Ronald
Abstract:: Measurements of inherent optical properties (IOP) were conducted over bottoms with different substrates by use of a sampling package mounted on and operated by a SCUBA diver. It was found that in areas of low ambient currents the distribution of IOP varies with bottom type in (1) its value relative...

Creator:: Zaneveld, J. Ronald, Roach, David M., and Pak, Hasong
Abstract:: 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...

Creator:: Pak, Hasong and Zaneveld, J. Ronald
Abstract:: Two separate time series observations of light transmission in the bottom water on the Continental Rise off Nova Scotia show fluctuations of light transmission in a wide range, 0-50% transmission at λ = 660 nm. The range corresponds approximately to SPM concentrations of 12 mg/l to 150 μg/l. The former...

Abstract:: 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...

Abstract:: We looked at the influence of temperature and salinity on the absorption coefficient of water with emphasis on the red and near-IR portions of the spectrum. The absorption coefficient of pure water was found to have a strong dependence on temperature and little dependence on salinity near the harmonics of...
