Sea Life Stirs the Ocean

jellyfishA recent study suggests that zooplankton, organisms that include krill and jellyfish, are capable of stirring ocean waters just like winds or tides.  The idea behind this research is actually an old one.  It is the idea that a body moving through a fluid tends to drag some of that fluid with it as it moves.  This means that even a tiny organism could have a significant impact on a large body of water such as the ocean.  This could mean that the impact of sea life should be calculated into climate computer models.  While the authors of the study are confident of this theory, many find it controversial.  For more information on the study and its critics, see National Geographic News.
