Photosynthetic responses as a function of light and temperature: Field and laboratory studies on marine microalgae

Photosynthetic responses as a function of light and temperature: Field and laboratory studies on marine microalgae

The aim of my thesis is to elucidate the different pathways of light in the marine environment, from underwater irradiance to the absorption of photons in microalgae. The pathway is followed through light harvesting and the subsequent electron transfer, to the fuelling of the photosynthetic process...
