Paper Abstract

Sea phytoplankton plays a considerable role in the interactive processes between light and the sea. Its species composition and the physiological development phase influence the spectrum of the light attenuation coefficient in the sea. Laboratory measurements of light attenuation spectrum were carried out on three different phytoplankton monocultures of the unicellular green algae Chlorella vulgaris and the larger Chlorella kesleri and the blue-green alga Chroococcus minor. The cultures were subjected to chemical (NaOH and temperature) or physical (ultrasounds) factors which altered their internal cell structures. Distinct changes in the light attenuation spectrum were observed as a result of the modification of the internal cell structures. Light attenuation cross-sections of those phytoplankton cells were also determined.
