Optical characterization of the oceanic unicellular cyanobacterium Synechococcus grown under a day-night cycle in natural irradiance

Academic Article


  • The optical properties of the oceanic cyanobacterium Synechococcus (clone WH8103) were examined in a nutrient-replete laboratory culture grown under a day-night cycle in natural irradiance. Measurements of the spectral absorption and beam attenuation coefficients, the size distribution of cells in suspension, and microscopic analysis of samples were made at intervals of 2-4 hours for 2 days. These measurements were used to calculate the optical properties at the level of a single "mean' cell representative of the actual population, specifically, the optical cross sections for spectral absorption, scattering, and attenuation. This study provides strong evidence that diel variability is an important component of the optical characterization of marine phytoplankton. -from Authors
