Light scattering by particles suspended in the sea: The role of particle size and density

摘要: Abstract Optical scattering and particle size measurements are reported at 78 stations along the south west coast of Britain. The composition particles is mainly mineral (70% by mass on average) light per unit concentration suspended particles, specific coefficient, was observed to vary over an order magnitude, from less than 0.1 1 m 2  g −1 . More 3 4 this variance explained changes in apparent density (dry weight/‘wet’ volume) mean particles. For data set, coefficient can be written b * M =(2.35/ ρD A ) where b* ρ D diameter area. standard error numerator equation 0.08. In fact, most (64%) differences with variations alone accounting for only 15% variance. Because coastal waters flocculate into aggregates containing organic material as well water, variable considerably solid material. Provided a suitable atmospheric correction visible-band imagery shelf seas applied, it may possible estimate using satellite remote-sensing reflectance two wavelengths. This work has shown that maps produced way will sensitive near-surface size. It may, however, use site-specific empirical relationships between derive both these parameters space.
