<HTML>Yuri, perhaps you might be able to answer this question.
I read some information about the unique properties of the Black Sea. As I understand it, it used to be a fresh water lake and melting glaciers from the late ice age raised the sea level of the Medditeranean, which eventually poured into the Black Sea. This, along with no natural temperature inversion, created an anoxic layer of water that started at approximately 600 ft. This layer has a kind of a bulge that causes it to temporarily rise as high as 100 ft. in certain areas. The anoxic layer is heavy with hydrogen sulfide which is highly corrosive to ferrous metals, such as u-boat hulls. (it also kills all marine life)
I was wondering if anyone knew of any reference to this corrosive layer as it affected u-boat operations. Was corrosion a problem for u-boats in that theater. If not the u-boats, did any of the cold war Soviet subs that prowled at much greater depths off the coast of Turkey run into any unusual problems with corrosion due to the water?
Thanks for your input,
