are of interest as these compounds are valuable as actinometry standards in the study of the efficiency of photosynthesis. No report seems to have been made of their absorption spectra ...

Absorption of a photon of sunlight propels photosynthetic pigments into their excited state, from which un-utilized energy is readily transferred to oxygen. Such a transfer to oxygen can be ...

The disappearance of sea ice in polar regions due to global warming not only increases the amount of light entering the ocean ...

Melting polar ice narrows the light spectrum underwater, favoring blue-tuned algae and disrupting the ocean food web.

Melting sea ice changes not only how much light enters the ocean, but also its color, disrupting marine photosynthesis and altering Arctic ecosystems in subtle but profound ways. As global warming ...
