TL;DR: In this paper, a multiple scattering correction was calculated from optical density spectral for 48 phytoplankton cultures of seven species representing a variety of cell sizes, pigment groups, and call-wall types.

TL;DR: In this paper, a model based on water's inherent optical properties (IOPs) has been developed to describe the vertical attenuation of visible solar radiation, which is an important parameter regarding ecosystems.

TL;DR: In this article, a multidisciplinary study was conducted in East Sound, Washington, USA between June 10 and June 25, 1998, using a nested sampling strategy utilizing four major types of platforms: (1) an array of 3 moored acoustical instrument packages and 2 moored optical instrument packages that recorded distributions and inten- sities of thin layers; (2) additional stationary instrumentation deployed outside the array comprised of meteorological stations, wave-tide gauges, and thermistor chains; (3) a research vessel anchored 150 m outside the western edge

TL;DR: In this article, the authors show that the Secchi disk depth (Z SD) may not exactly represent the sighting of a Secchi disc by a human eye. And they develop a new theoretical model to interpret Z SD, which relies only on the diffuse attenuation coefficient at a wavelength corresponding to the maximum transparency.

TL;DR: In this article, the relative importance of package effects and pigment composition in contributing to variations in spectral absorption in shelf waters off North Carolina during May 1997 and off west Florida during October 1998 was assessed.
