  • Assessment of the relationships between dominant cell size in natural phytoplankton communities and the spectral shape of the absorption coefficient 

    Ciotti, Aurea M., Marlon R. Lewis, and John J. Cullen. 2002. "Assessment of the relationships between dominant cell size in natural phytoplankton communities and the spectral shape of the absorption coefficient." Limnology and Oceanography 47(2): 404-417. DOI:10.4319/lo.2002.47.2.0404
    Size-fractionated chlorophyll concentration and phytoplankton absorption spectra were compared for a wide variety of natural communities. We found that, in general, when phytoplankton abundance increases, larger size-classes ...

  • Inferred influence of nutrient availability on the relationship between Sun-induced chlorophyll fluorescence and incident irradiance in the Bering Sea 

    Schallenberg, Christina, Marlon R. Lewis, Dan E Kelley, and John J. Cullen. 2008. "Inferred influence of nutrient availability on the relationship between Sun-induced chlorophyll fluorescence and incident irradiance in the Bering Sea." Journal of Geophysical Research.C.Oceans 113(7). DOI:10.1029/2007JC004355
    This study examines variability in the relationship between Sun-induced chlorophyll fluorescence and incident solar irradiance as a potential diagnostic of the nutritional status of phytoplankton. The study site is the ...

  • 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 ...
