The paper is an overview of the Baltic Sea and its basin characteristic. The geographical location and climate and weather of the Baltic Sea region according to its zones and seasons were described. Moreover, the abiotic parameters of water such as salinity, oxygen concertation and temperature distribution in the water column were explained.
