Mysterious ocean feature found in Tasman Sea

An unusual water feature, described as a 40km-wide disc, has been detected travelling south of Australia in the Tasman Sea, around Tasmania and possibly as far as the Indian Ocean.
New deep-diving ocean gliders have discovered the 200m-deep formation in ocean eddies formed by the East Australian Current. Scientists from the CSIRO and the University of Technology Sydney (UTS) report the discovery in the journal Geophysical Research letters.

The familiar model of Atlantic ocean currents that shows a discrete "conveyor belt" of deep, cold water flowing southward from the Labrador Sea is probably all wet.
New research led by Duke University and the Woods Hole Oceanographic Institution relied on an armada of sophisticated floats to show that much of this water, originating in the sea between Newfoundland and Greenland, is diverted generally eastward by the time it flows as far south as Massachusetts. From there it disperses to the depths in complex ways that are difficult to follow.
A 50-year-old model of ocean currents had shown this southbound subsurface flow of cold water forming a continuous loop with the familiar northbound flow of warm water on the surface, called the Gulf Stream.
