Abstract
    The unique physical characteristics of Arctic and Antarctic polynyas often make them highly productive marine environments. Here I focus on four major polynyas (the NEW and NOW polynyas in the Arctic and the Ross Sea and Mertz Glacier polynyas in the Antarctic) and compare and contrast the major physicochemical features that control rates of phytoplankton growth and primary production in each. Included in this analysis are the effects of temperature, solar radiation (including ultraviolet), and nutrient delivery. Also discussed is the positive feedback that exists between cloud cover and polynya size as well as the importance of the timing of polynya formation on ecosystem structure.
