The unique Baltic Sea. The Baltic Sea is the youngest sea of our planet. … Due to massive freshwater runoff from the land and limited salt water inflows from the Danish straits, the salinity of the Baltic Sea is much lower than that of the oceans, and the water is considered to be brackish water instead of sea water.
Why is the Baltic Sea so special to live in?
1. Geographical position, geological development, hydrographical features, climate and physical drivers together create the Baltic Sea environment. … Being a semi-enclosed continental sea with a large drainage area compared to its water volume, the Baltic Sea ecosystem is heavily impacted by the surrounding landmasses.
How does the Baltic Sea differ from other seas?
The Baltic Sea is relatively isolated from other seas, and has only a narrow connection to the North Sea through the Sound and the Belt Seas. Hence, it takes approximately 30 years for the Baltic Sea waters to be fully exchanged (Stigebrandt 2001). Marine water enters the Baltic Sea predominantly during winter storms.
Why is the Baltic Sea so polluted?
The Baltic Sea is almost totally surrounded by land and therefore more endangered by pollution than other marine areas. The sources of marine pollution are municipal and industrial waste inputs directly into the sea or via rivers, and atmospheric inputs mainly from traffic and agriculture.

These mobile top predators have an important role in regulating the food web, but are also sensitive to pressures in all their areas of distribution, as well as to changes in the food web.
Why salinity is low in Baltic Sea?
Answer : Salinity is low in the land locked Baltic Sea because of the high temperature. The fresh water from the surrounding land gets run off and the salt density is also low. The Baltic Sea is almost land-locked and covers an area of “122415 000 km”.
