The Seas not Mingling with One Another

One of the properties of seas that has only recently been discovered is related in a verse of the Qur'an as follows:

<SNIP>

Unfortunately for Allah, the seas do mingle. The concept of "clines" (thermocline, pynocline, halocline) is well understood today, and was observable to ancient sailors. No matter though, because, while these clines do form a gradient, they are permeable and definitely allow "mingling". From the wiki page on pycnoclines:

Pycnoclines become unstable when their Richardson number drops below 0.25. The Richardson number is a dimensionless number expressing the ratio of potential to kinetic energy. This ratio drops below 0.25 when the shear rate exceeds stratification. This can produce Kelvin-Helmholtz instability, resulting in a turbulence which leads to mixing.[11]

The changes in pycnocline depth or properties can be simulated from some computer program models. The simple approach for those models is to examine the Ekman pumping model based on the ocean general circulation model (OCGM).[12]

Notice the bit about "turbulence which leads to mixing".

Below the mixed layer, a stable density gradient (or pycnocline) separates the upper and lower water which hinders vertical transport.[2] This separation has important biological effects on the ocean and the marine living organisms. However, vertical mixing across pycnocline is a regular phenomenon in oceans, and occurs through shear-produced turbulence.[3] Such mixing plays a key role in the transport of nutrients.[4]
