Scientists have long chalked up ocean mixing of salt, heat, nutrients, and gases, such as oxygen and carbon dioxide, to wind and tides. New research is investigating another possible contributor: krill. Mixing ocean water may seem like a big job for such a tiny creature, but krill are a force of nature when they migrate in giant swarms to feed at night. Part of the "Science Nation" series.
