We study the effects of ozone depletion on primary production in ice‐covered and open polar waters using a spectral radiative transfer model combined with a parameterization of the inhibition of marine photosynthesis by ultraviolet radiation. We find that ozone depletion might not have a negative influence on the aquatic algal community at high latitudes but instead could enhance primary production. For an ozone depletion of 50%, we estimate the yearly averaged enhancement to be about 1%.
