During November-December 1987, a series of experiments were conducted at Palmer Station, Antarctica, to study the effects of ultraviolet radiation (UV) on phytoplankton collected from Arthur Harbor, Anvers Island, Antarctica. Three parameters were studied: (1) primary production rates, (2) photosynthetic pigments, and (3) photosynthesis-irradiance responses. These parameters were monitored during short-term and relatively long-term exposures to varying levels of UV radiation. The results of this month-long study provide evidence of some potential deleterious effects of enhance UV radiation of Antarctic phytoplankton. The implications of these findings to our understanding of the ecology of the Southern Ocean as discussed.
