Motion of ocean’s small swimmers may be important for climate modeling
Small ocean dwellers like krill don’t idly go with the flow. In fact, the water around such animals flows with their go, new research has found, suggesting tiny swimmers may have a big impact on ocean mixing.
Energy put into the oceans by small animals is a significant component of the total contributed by all swimming creatures, adding up to a force comparable to that of winds and tides, scientists report in the July 30 Nature. The research suggests that scientists modeling global climate processes may need to add the contribution of such swimmers to the mix.
