The coalescence of two East Australian current warm-core eddies.
Two warm-core eddies coalesced in about 20 days as their centers rotated around a point on the contracting line that joined them. In the process of forming the new eddy, the subsurface isothermal-isohaline "signature" layer of one eddy was uplifted and somewhat depleted while that of the other was depressed.
