Abstract
    The dependence of phytoplankton photosynthesis on available light is the fundamental biological process relevant to the ecology of tidal fronts. The leading physical process is vertical mixing, through its control on the supply of nutrients essential for growth and on the irradiance experienced by phytoplankton cells. These two processes comprise a simple explanation for enhanced primary production in the vicinity of fronts. Increased understanding can be obtained, for example, from further consideration of the possible mechanisms of nutrient supply. Estimates are made here of the cross-frontal nutrient transfer at the Ushant and Georges Bank fronts, the hypothesis of nutrient complementarity is discussed, and suggestions are made for future research.
