Laser-guided 'sea monkeys' hint at secrets of ocean's motion

Could the humble brine shrimp, a few millimeters in length, be partly responsible for the large-scale motion of the ocean? That’s the finding from a pair of Caltech researchers, who used lasers to herd brine shrimp around a tank and track their effects on the water’s movement. The results, published in the journal Physics of Fluids, show that ocean currents may be a function not only of large-scale physical phenomena like wind and tides, but also of living things. Study coauthor John Dabiri, a Caltech fluid dynamicist, latched on to the idea a few years ago while studying how jellyfish move. He noticed something strange: As the jellyfish swam, they appeared to be carrying a...
