Paper Abstract

The value of the yellow substances absorption coefficient in the visible-light spectrum is a very important characteristics used in the optical classification of sea waters. This quantity also needs to be included in algorithms for the remote detection of optically-active sea water constituents. An extensive data base of measurements of optical parameters has been collected during series of cruises since 1993 in different water masses of the southern Baltic. The yellow substance absorption coefficient at wavelength 400 nm and yellow substance absorption spectrum slope coefficient were calculated, and the statistical distribution of values of those parameters in the three various waters masses (bay waters, coastal and open sea waters) is presented. The seasonal variability of both parameters in the three regions is analyzed. Results are discussed and compared of with published record of yellow substance properties and variability pattern of other optical properties in the Southern Baltic.
