Abstract

A simple model, utilizing recent data, is used to estimate the potential impact of increased UV-B on aquatic primary productivity. The model is then utilized to emphasize major uncertainties in our present predictive capabilities. These (generally non-linear) uncertainties, which are much larger than the current linear conclusions drawn from our simple model, include: (1) the identification and quantification of the relevant photoprocesses and their biological weighting functions as well as the limitation of l4C techniques as currently and routinely used; (2) the possibility of community structure change, due to increased UV-B stress, and the consequent potential for tropodynamic changes in the food chain; (3) the influence of water column mixing on the determination of biologically effective doses and photosynthetically available radiant energy incident on and available to phytoplankton.
