Zooplankton like krill may be small, but they are mighty! Because so many marine animals depend on these tiny animals for food, their size and abundance can tell researchers a lot about how healthy an ecosystem is. When there's lots of krill, there also tends to be plenty of seabirds and marine mammals around. Researchers from Greater Farallones National Marine Sanctuary work with ACCESS to survey the zooplankton in the sanctuary -- check out our video to learn more! #EarthIsBlue
