DESCRIPTION:Enceladus\, a small icy satellite of Saturn\, was found to hav
 e a subsurface water ocean and evidence of ongoing hydrothermal activity i
 n the seafloor. The ocean water\, sampled via the polar plume\, was inferr
 ed to contain substantial levels of inorganic and organic carbon as well a
 s ammonia. However\, there are very few constraints on the availability of
  other bio-essential nutrients\, including phosphorus\, sulfur\, iron\, an
 d other enzyme-supporting metals\, as well as biomolecules. This talk will
  summarize our current understanding and report some ongoing research abou
 t the availability of these nutrients and biomolecules. Furthermore\, I wi
 ll overview the limiting nutrient and possibly additional limiting factors
  for the origin and survival of life in the subsurface oceans of some icy 
 moons. These considerations can help in defining future astrobiology missi
 ons to the outer solar system and beyond.\n\n
