DESCRIPTION: \nThe evening begins with an optional social hour and pot luck supper at 
 6:30 pm,\nfollowed by the film at 7:30 pm, followed by a discussion at the 
 end of the film.\n \nFROZEN SEAS\n \nThis film compares oceanic life in the 
 Arctic and Antarctica.  The winter in these regions brings temperatures of 
 minus 50°C and frozen seas ─ creating the biggest challenge to life.  
 However, there are polynyas in the Arctic which are free of ice owing to 
 the pressure of currents on either side and such places do provide refuge 
 for some species, like the walrus and the bowhead whale.  A pod of belugas 
 is shown:  their movements are limited to a single hole in the ice ─ 
 putting them at risk of attack from polar bears.  Everything changes with 
 the arrival of summer when melting ice brings a variety of migratory 
 visitors.  At the other end of the planet, in the Antarctic, winter is even 
 more harsh, but emperor penguins and Weddell seals stay throughout.  Under 
 the sea ice, krill shrink in size and revert to their juvenile form in 
 order to save energy.  Chinstrap penguins travel to the north, beyond the 
 ice, but return during the spring to breed.  Having managed to get ashore, 
 they have to walk a great distance to find a nest site, and the most 
 favored is Zavodovski Island, an active volcano whose warmth keeps ice from 
 forming.  Further south, as the icebergs break up, humpback and minke 
 whales appear, their target the abundant krill.  The leopard seal is the 
 Antarctic's top predator. It is most effective underwater, and emperor 
 penguins propel themselves at speed through its territory.  Nonetheless, it 
 almost invariably makes a kill.\n \nWheelchair accessible around the corner 
 at  411  28th  Street\n \n$5 donations are accepted\n
