Baltic Sea, Estonia

The Baltic Sea in northeast Europe possesses the characteristics of seas, lakes and estuaries, but is in fact a sea. Technically, it is classified as a brackish sea, meaning it is not entirely fresh and not entirely saline. The Baltic Sea is joined to the Atlantic Ocean through three straits in Denmark: the Oresund, Great Belt and Little Belt. It isn’t landlocked, but it does border many countries, including Russia, Finland, Sweden, Denmark, Germany, Poland, Lithuania, Latvia and Estonia – which is featured in today’s image.
