ABSTRACT
Presents a pulsed photoacoustic spectroscopy (PAS) technique for immediate measuring absolute optical absorption coefficient. Use of amplitude-time characteristics of photoacoustic (PA) signal generated in air surrounding the sample under investigation as basis of the technique; Derivation of the time dependence of PA signal for each PA cell chamber.

    Crater Lake, Oregon, is a mid-latitude caldera lake famous for its depth (594 m) and blue color. Recent underwater spectral measurements of solar radiation (300–800 nm) support earlier observations of unusual transparency and extend these to UV-B wavelengths. New data suggest that...
