The effects of increased PAR and UV on the xanthophyl cycle of Antarctic ice algae
Entry ID: K068_2005_2006_NZ_1

Abstract: The xanthophyll cycle is a photo-protection mechanism in phytoplankton which protects the photosynthestic machinery from damage by high light intensities. Sea ice algae in Antarctica live on the bottom of sea ice often at low irradiances. During sea ice break up, they become exposed to high levels of irradiance. This cycle was investigated in Antarctic sea ice to determine, a) how does the ... View entire text
