The biologically effective ultraviolet irradiance at the earth's surface varies with the elevation
of the sun, the atmospheric ozone amount, and with the abundance of scatterers and …

Cnidarians which contain symbiotic algae are constantly faced with the challenges of a
changing photic regime and a hyperoxic environment. Zooxanthellae (Symbiodinium sp.) …

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 …

Marine organisms in the upper layers of the sea may be endangered by increased ultraviolet
radiation resulting from declines in the thickness of stratospheric ozone. Evidence …

The attenuation of ultra-violet radiation (UV) is described for the waters of Kaneohe Bay,
Hawaii. The attenuation rates for UV varied with water turbidity and were similar, or greater …

]'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 …

Increases in UV‐B radiation resulting from ozone depletion during austral spring could
potentially alter the balance of the Southern Ocean marine ecosystem. A quantitative …

The enzymes Superoxide dismutase, catalase and ascorbate peroxidase, which provide
protection against toxic forms of oxygen, consistently show a positive correlation between …

Lipophilic pigments were examined in microbial mat communities dominated by
cyanobacteria in the intertidal zone and by diatoms in the subtidal and sublittoral zones of …

Natural populations of the sea anemone Aiptasia pallida containing endosymbiotic
dinoflagellates were acclimated to different irradiance regimes, with and without ultraviolet …
