Lead author of the study and an expert in sea level science, Professor Chris Hughes, said: «What we found was a pair of
eddies spinning in opposite directions and linked to each other so that they travel together all the way across the Tasman Sea, taking six months to do it.
The «smoke - rings» are a pair of linked
eddies spinning in opposite directions that travel up to ten times the speed of «normal» eddies and were spotted in the Tasman Sea, off the southwest of Australia and in the South Atlantic, west of South Africa.
Eddies spin behind a speeding boat, smoke billows from an erupting volcano, and an airplane lurches through «empty» air.
When
these eddies spin counterclockwise they bring water from the depths up toward the surface.

An
eddy roughly 70 miles wide has
spun off in the past few weeks from the current, roughly 100 miles west of the southern tip of Florida, Peacock told reporters yesterday, adding that it now shows a slight reattachment.
It had
spun clockwise around the edge of the plume and then gradually moved toward the middle, as if caught in a giant
eddy.
From June through July 2015, that wavy jet stream had
spun off an
eddy, known as a «cut - off high.»
«We should be able to watch the turbulent
eddies [
spin] around; a bit like watching turbulent water in a stream.»
But there's a new generation of inductive bike lighting coming of age right now, which uses the naturally - generated
eddy currents from the
spinning wheel of the bike to produce enough electricity to drive bright (and energy - efficient) LED bulbs, and which promises to set cyclists free from the dreaded dead battery blues.
Reelight, the Danish bike lighting innovator that has previously won a Red Dot Design award and several Eurobike Awards for its products, is launching another unique LED bike head - and taillight that is powered by
eddy currents generated by a
spinning bicycle wheel, with its new NEO prototype promising to be the «world's most powerful friction - free bikelight.»
The movement drives storms
spinning off the polar vortices and surface ocean
eddies moving in Ekman spirals towards the coast of the Americas.
Another great unknown was the interaction between currents like the Gulf Stream and the giant
eddies that the currents
spun off as they meandered.
Counter currents and gyres created by bottom features such as the Pourtalès Terrace in the Florida Current and the Charleston Bump in the Gulf Stream help retain the pelagic larvae within the area of the Florida Keys and SAB, respectively, by causing persistent gyres and
eddies that
spin off the current and retain their pelagic flora and fauna, some of which recruit to benthic and pelagic habitats in the region.
