Even Tiny Organisms Can Stir Up an Ocean

Image
What gets the sea all riled up? Winds and tides do, certainly, but scientists have long wondered how the movement of fish and other organisms — even tiny ones, like zooplankton — might contribute to ocean mixing.

A study by Kakani Katija, a doctoral student at the California Institute of Technology, and her adviser, John O. Dabiri, has determined that the movement of the ocean’s organisms makes a significant contribution. But the researchers are not talking about the effects of swishing fins or flippers. Rather, they report in the journal Nature, the mixing is caused just by the movement of bodies through the water.
