Austral spring ozone depletion results in exposure of phytoplankton in the Weddell-Scotia Confluence to enhanced surface ultraviolet-B radiation (UV-B, 280 to 320 nanometers). Since this is an area of high phytoplankton biomass during the early spring, an investigation was made of possible effects of increased UV-B on the phytoplankton productivity during October and November 1993 aboard the R/V Nathaniel B. Palmer (UV-B/Ozone 93). The measurements made during the studies included phytoplankton UV absorbance (this paper) as well as phytoplankton photosynthesis, nutrient uptake, pigment composition, and growth rates. 10 refs., 3 figs.
