decision on the annual celebration of the Day of the Baltic Sea (Baltic Sea Day ) was adopted in 1986 at the 17th meeting of the Helsinki Convention.
History and development of the Baltic Sea, located in northern Europe and owned by Atlantic Ocean basin, began the retreat of the last glacier Valdai approximately 15,000 years ago, when the edge of the glacier extends along the southern border.
size of the glacier was huge — its thickness is reached over a mile, and when he pulled back, then on their way flattened hill, scratching and grabbing a solid rock with a mass of loose material, gravel and boulders.
Today Baltic Sea — a major transport corridor linking Russia, Europe and AziyuPri this ice turned into a huge mass of water, the sea level rose, and published a series of pre-glacial lakes. With the retreat of the glacier, these lakes are joined together in a single Baltic glacial lake, it was very cold, it even floating icebergs.
From ancient times until the 18th century Baltic Sea was called in Russia "Varangian Sea". Middle depth of the Baltic Sea is about 51 meters, and the highest — 470 meters.
Today the Baltic Sea — an important transport corridor linking Russia, Europe, and Asia. It washes the shores of Russia, Estonia, Latvia, Lithuania, Poland, Germany, Denmark, Sweden and Finland. In recent years, however, environmentalists argue that the waterway corridor littered with debris and badly in need of cleaning.
