Tiny marine organisms may affect ocean mixing

Today's Video of the Day from the National Science Foundation describes how krill and other tiny marine organisms could play a role in ocean mixing. Each night, swarms of millions of krill move to the surface of the ocean to feed. Researchers at Stanford University recreated this activity in the lab to understand the fluid movement that is involved. According to the experts, if the vertical migrations of krill are affecting ocean mixing, this must be accounted for in models which …
