Spectral irradiance measurements. from 310 to 650 nm. have been made in low and
modcrately productive ocean waters. These new data and selected earlier clear ocean water …

ABSTRACT UV radiation (UVR) is a significant ecological factor in the marine environment
that can have important effects on planktonic organisms and dissolved organic matter …

Direct measurements of the downwelling spectral irradiance in the middle UV (280–340 nm)
have been made for a range of solar zenith angles (20°‐70°). These measurements were …

A quantitative analysis of the wavelength‐dependent influence of solar irradiance on natural
phytoplankton photosynthesis has been made. The effect on productivity due to several …

The problem of trying to determine the effect of solar ultraviolet radiation (UVR) on aquatic
organisms is much more difficult than that of assessing the impact of UVR on terrestrial …

An inexpensive, easily deployed polymer film was used to measure the penetration of
ultraviolet (UV) radiation in nearshore tropical water. Measurements were made to a depth …

A biological dosimeter has been developed for use in aquatic environments. This method is
based on the sensitivity of a DNA repair‐deficient strain of Escherichia coli (CSR06) to …

The objectives of the research program reported upon here were (1) to measure ambient
levels of UV radiation and determine which variables most strongly affected its attenuation in …

Penetration of ultraviolet radiation (UVR) into natural waters depends on the concentration
and optical qualities of dissolved organic matter (DOM), phytoplankton, other suspended …

]'4 ARINE LIFE IN THE UPPER layers of the sea may be endangered by increased
ultraviolet (UV) radiation resulting from reduction in the thickness of the earth's ozone layer …
