The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. It is a shelf sea and marginal sea of the Atlantic with limited water exchange between the two, making it an inland sea. The Baltic Sea drains through the Danish straits into the Kattegat by way of the Øresund, Great Belt and Little Belt.
Øresund is a geologically young strait that formed 8,500–8,000 years ago as a result of rising sea levels. Previously, the Ancylus Lake, a fresh-water body occupying the Baltic basin, had been connected to the sea solely via the Great Belt. The incursion of salt water via Øresund marked the beginning of the modern Baltic Sea as a salt-water ...

The freshwater runoff entering the Baltic sea accounts for two percent of its volume. [4] A narrow connection to the North Sea means that water stays in the Baltic for an average of 30 years. These two characteristics work to make the Baltic Sea one of the largest brackish bodies of water in the world. The Gulf of Riga has an average salt ...
The Baltic Sea saltwater inflow, known as the major Baltic inflow (MBI), refers to a significant influx of saline water from the North Sea into the Baltic Sea through the Danish straits. In the Baltic Sea, dense seawater from the North Sea sinks to the bottom and moves along the seabed, displacing the often oxygen-depleted water in the deep ...
Seawater, or sea water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium ( Na +
The Baltic herring, known as strömming in Swedish, is smaller than the Atlantic herring found in the North Sea. Traditionally, strömming is defined as herring caught in the brackish waters of the Baltic north of the Kalmar Strait. [1] The herring used for surströmming are caught prior to spawning in April and May.
Originally the Eridanos river system prior to the Pleistocene, since then it has been flooded by the North Sea but still receives so much freshwater from the adjacent lands that the water is brackish. As seawater is denser, the water in the Baltic is stratified, with seawater at the bottom and freshwater at the top. Limited mixing occurs ...
