Culture bottles used for “C productivity experiments transmit different amounts of ultraviolet radiation depending on their glass composition. A quantitative assessment of the spectral irradiance penetrating three commonly used glass types has been made. By assuming a biological efficiency for photoinhibition, the biologically effective dose within each type of bottle can be quantitatively calculated. The biologically effective dose is reduced about 6% by quartz bottles, 13% by Pyrex bottles, and 22% by Wheaton glass bottles at the water surface. These effects become smaller with increasing depth in in situ measurements.
