Lähivesille

Lähivesille, also known as the Gulf of Finland, is a marginal sea of the Baltic Sea located between the mainland of Finland and the island of Estonia. It is connected to the Baltic Sea via the narrowest part of the Gulf of Riga, known as the Irbe Strait. The Gulf of Finland is approximately 180 kilometers long and 90 kilometers wide, with a maximum depth of 120 meters.

The Gulf of Finland is known for its unique ecosystem, which includes a variety of marine life such as fish, birds, and marine mammals. The sea is also an important fishing ground, with species such as cod, herring, and sprat being commonly caught. The Gulf of Finland is also a popular destination for recreational activities such as boating, swimming, and fishing.

The Gulf of Finland is influenced by the climate of the Baltic Sea, which is characterized by cool summers and mild winters. The sea is also affected by the freshwater input from the Neva River, which flows into the Gulf of Finland from the city of Saint Petersburg in Russia. This freshwater input can lead to the formation of a halocline, a layer of water with a sharp change in salinity, which can affect the distribution of marine life in the Gulf of Finland.

The Gulf of Finland is also an important transportation route, with several ports located along its shores. The sea is used for the transportation of goods and people, as well as for the extraction of natural resources such as oil and gas. The Gulf of Finland is also an important area for scientific research, with several research institutions located along its shores. These institutions study a variety of topics related to the Gulf of Finland, including its ecology, geology, and climate.
