Satellites have shown two mysterious 'black hole' whirlpools in the South Atlantic ocean - ultra powerful “vortexes” which suck water down into the depths. The whirpools - never witnessed before - would suck down ships, debris and even living creatures, moving 1.3 million cubic metres of water per second.
Any idea how wide these things are?
And much like astronomical black holes, oceanic eddies exhibit singularity.
To locate these oceanic black holes, the scientists examined satellite images of the Agulhas Current in the Indian Ocean. The current travels along the east coast of Africa before turning back on itself in a loop. The loop occasionally pinches off and forms eddies that whirl off into the South Atlantic Ocean, remaining intact for more than three months.
The eddies are a coherent island of water in an otherwise turbulent ocean. As such, they “create moving oases for the marine food chain or even impact climate change through their long-range transport of salinity and temperature,” the study states. The eddies will capture any detritus floating nearby and swallow it, thereby transporting oil and garbage. And nothing within leaks out.

The singularities, as they have been termed, last for months at a time, moving across the ocean without interference from other currents. Thus they can transport water of different temperatures and salinity to other areas of the ocean, potentially influencing the regional climate.
Haller and Beron-Vera found that the vortices transported water in a north-western direction 30% faster than had previously been reckoned – at a rate equating to 1.3 million cubic metres of water per second. In addition, the maelstroms were found to occur four times deeper in the ocean than previously estimated; the study found examples as deep as 2000m below the surface.

You need to take smaller bites and chew better when you eatedit on 21-8-2013 by Biigs because: (no reason given)
magnetic centrifugal force being generated by the earth rising up through the sea.
or a sinkhole/cave/pyramid/large pocket being filled with water?

Can't see it to be honest as they move quite a distance

In Greek mythology, Charybdis (or Kharybdis) was once a beautiful naiad and the daughter of Poseidon and Gaia. She assumes the form of a huge bladder of a creature whose face is all mouth and whose arms and legs are flippers.[citation needed] She swallows a huge amount of water three times a day, before belching it back out again, creating large whirlpools capable of dragging a ship underwater. In some variations of the story, Charybdis is simply a large whirlpool instead of a sea monster. Once a lovely maiden, Charybdis was loyal to her father in his endless feud with Zeus. She rode the hungry tides after Poseidon stirred up a storm, directing them onto beaches, destroying entire villages, submerging fields and drowning forests, claiming all in her path for the sea. She claimed so much land for her father's kingdom that Zeus became enraged and changed her into a monster. In mythology Charybdis lies on one side of a narrow channel. Opposite her is Scylla, another sea-monster. The sides of the strait are within an arrow shot of each other, and sailors attempting to avoid one of them will come in reach of the other. 'Between Scylla and Charybdis' thus means to having to choose between two dangers, either of which brings harm. The theoretical size of Charybdis remains unknown, yet in order to consume Greek ships the whirlpool can be estimated to about 75 feet across. Charybdis has been associated with the Strait of Messina, off the coast of Sicily and opposite a rock on the mainland identified with Scylla.[1] Were Charybdis to be located in the Strait of Messina it would in fact have the size to accommodate the whirlpool. A whirlpool does exist there, caused by currents meeting, but it is seldom dangerous.
