Jellyfish and Fish May Be Climate Movers November 4, 2011
Jellyfish
Instruments able to track movements of tiny particles around jellyfish and other swimming creatures show just how much water they are moving.
Jellyfish and other creatures in the sea may have a significant impact on climate as they churn the water of the world’s oceans, according to researchers.

The controversial theory was first proposed in 2009 by scientists at the California Institute of Technology.

Now, a new device that lights up the tiny particles around the marine animals when they swim hints at just how much water they can move about.

Dr. Kakani Katija Young and colleagues at the Woods Hole Oceanographic Institute write in the Journal of Visualized Experiments that the movements of all combined ocean life could have an impact on the ocean climate comparable to that of wind.
