Any Oceanographers here?

[SloggingScotsman]

Long shot I know, but you never know.

If you had some sort of activity in the area of the Tonga Trench, e.g. Plate movement, nuclear sub having an accident, whatever, given the flow of the South Equatorial Currents, and the flow that appears to go around the north of Australia:-

1. Is it possible that wave effects, debris, pollution, whatever, could find its way towards the middle of the Indian Ocean?
2. How likely is that to happen? As opposed to simply circling down the East coast of Australia.
3. If material did find its way into the middle of the Indian Ocean, then are there any oceanographic reasons why it could get a bit of a gentle 'kick' propelling it towards the coast of Africa? Now I know that the Equatorial Current would do that naturally, but I am looking for structural reasons why there could be a mid way boost or kick, albeit relatively gentle.

Thanks in advance.

1. Yes.
2. Depends on size and density but typically p is of the order of 2.7 x 10^-10 to 1 x 10^-15 depending on the relative density of the object.
3. Yes.
