Welcome to Half-Life Answers. What would you like to know?

Considering that Half-Life 2 is to take place in a Russian/European landscape, it is most likely the sea closest to the border of Russia and Europe, so I would have to say the Black Sea. And since most of the rebel propaganda (Such as the born poster) is written in English and not Russian, it has more evidence to support it being on the border.
