Abstract

Optical measurements performed during the summer of 1997 from an off-shore oceanographic tower in the northern Adriatic Sea in the presence of so-called mucilage matter are presented. The presence of mucilage layers, was associated with the observation of unique patterns in the vertical distribution of both apparent and inherent optical properties which exhibited very sharp subsurface maxima. These layers were characterized by very high values of the diffuse attenuation coefficient of upwelling radiance and the beam attenuation coefficient, as well as, the ratio of the scattering and absorption coefficients at all wavelengths . The mucilage data were compared to non-mucilage observations and two situations came out regarding the surface signal.
