  • Modeling the effects of ultraviolet radiation on embryos of Calanus finmarchicus and Atlantic cod (Gadus morhua) in a mixing environment 

    Kuhn, Penny S., Howard I. Browman, Richard F. Davis, John J. Cullen, et al. 2000. "Modeling the effects of ultraviolet radiation on embryos of Calanus finmarchicus and Atlantic cod (Gadus morhua) in a mixing environment." Limnology and Oceanography 45(8): 1797-1806. DOI:10.4319/lo.2000.45.8.1797
    It is well established that ultraviolet radiation (UVR, 280-400 nm) harms aquatic organisms. Reductions in productivity have been reported for phytoplankton, ichthyoplankton, and zooplankton in incubations exposed to UVR. ...

  • Optical detection and assessment of algal blooms 

    Cullen, John J., Aurea M. Ciotti, Richard F. Davis, and Marlon R. Lewis. 1997. "Optical detection and assessment of algal blooms." Limnology and Oceanography 42(5 PART 2): 1223-1239. DOI:10.4319/lo.1997.42.5_part_2.1223
    Concerns about harmful algal blooms (HABs) have grown in recent years. There is a pressing need for robust, quantitative, and cost-effective methods to detect and characterize algal blooms. Critical applications of these ...

  • Spectrally weighted transparency in models of water-column photosynthesis and photoinhibition by ultraviolet radiation 

    Lehmann, Moritz K., Richard F. Davis, Yannick Huot, and John J. Cullen. 2004. "Spectrally weighted transparency in models of water-column photosynthesis and photoinhibition by ultraviolet radiation." Marine Ecology Progress Series 269: 101-110. doi:10.3354/meps269101
    We present a simple method for describing the influence of variable attenuation of spectral irradiance, Kd(lambda), on water-column photosynthesis and its inhibition by ultraviolet radiation (UV). The approach is based on ...
