mekata pehedili kireemak nedda...

Math hoyanawa mekata hetuwa saho. Kisima thenaka hariyata na mekai hetuwa kiyala. Meka tamai godak denek anumatha karana adahasa :

There are two mechanisms for mixing at a liquid-liquid interface, firstly diffusion and secondly physical agitation.

Diffusion is negligably slow in liquids, it takes days for solutes to travel a few centimetres, so the mixing is dominated by physical agitation e.g. wave action, convention currents, wind mixing etc.

In this particular case it's hard to judge what effect waves and wind have. The sea looks very calm, so I'd guess that waves and wind have little effect and it's not that surprising that mixing is slow. I bet that line wouldn't be as well defined the morning after a storm.
