The rings have been noticed by analysing sea stage measurements taken from satellites along with sea floor temperature photographs from the identical time and place.
“My pondering is that these linked, fast-paced eddies may ‘suck-up’ small marine creatures and carry them at excessive velocity and for lengthy distances throughout the ocean,” mentioned Chris Hughes, professor on the College of Liverpool within the UK.
The ocean is filled with eddies, swirling motions some tens to a whole lot of kilometres throughout, which combine the water and carry it throughout the typical currents.
The ‘smoke-rings’ are a pair of linked eddies spinning in reverse instructions that journey as much as ten instances the velocity of ‘regular’ eddies and have been noticed within the Tasman Sea, off the southwest of Australia and within the South Atlantic, west of South Africa.
The rings within the ocean are minimize in half by the ocean floor, so we see the 2 ends of the half ring on the floor, researchers mentioned.
“What we discovered was a pair of eddies spinning in reverse instructions and linked to one another in order that they journey collectively all the best way throughout the Tasman Sea, taking six months to do it,” mentioned Hughes, lead writer of the examine revealed within the journal Geophysical Analysis Letters.
“Ocean eddies nearly at all times head to the west, however by pairing up they’ll transfer to the east and journey ten instances as quick as a traditional eddy, in order that they carry water in uncommon instructions throughout the ocean,” mentioned Hughes.
“The smoke rings require an space of calm water to ‘puff’ out by means of, which itself is sort of uncommon. I’ve checked out different areas of different oceans however I’ve solely seen them within the oceans round Australia, plus one within the South Atlantic,” he added.
