      Polynas play an important role in heat transfer from the oceans to the atmosphere, ice production, the formation of dense shelf water, spring disintegration of sea ice, phytoplankton and zooplankton production, and the distribution of higher trophic animals such as cephalopods, fish, birds, seals, and cetaceans. Within polynas, the oceanic heat loss may be 10–100 times above that of the ice-covered surface.
