Yes, it spirals around seasonally, I guess because of the rivers adding water and the Bosporus subtracting water. I had thought that the glacial melting from the last Ice Ages made the sea's upper water column pure freshwater, but I guess it's more like mixed brackish water now.

Is that due to silt-mud in the water or due to algae?

rarely the visibility is arround 6 to 10 meters and only in winter and spring time [allthought there are somme exceptions in september]...
because this sea is not clear, the diving certificates are somehow difficult to be obtained....al the exercises are easely made in clears waters...
as you know, the black sea is not an open sea....she comunicate with mediteranean sea thrue bosfor and dardanele straits, therefor there are not streams, but i must tell u that is not a calm sea.
shurelly is a salt water sea, but not so salt as the mediteranean is or adriatic....whay is that?
because a large amount of fresh water is brought by Danube river...
on the romanian seashore, the black sea have sandy beaches [did I spell corectly?]

Yes. So there are many rough waves from the winds of the surrounding mountains, I guess, but no daily tide.

PS. I just happened to see this book about the pre-history of the Black Sea, the paleo-ecology and coastal peoples there, see the Table of contents for details about "the flood", molluscs, fish etc.
