Question

почему соленость вод Балтийского моря ниже, чем вод Баренцева моря. Чем это объясняется?

Answer 1

Чем больше величина испарения, тем больше соленость морской воды, поскольку при испарении остаются соли. На изменение солености большое влияние оказывают океанические и прибрежные течения, вынос пресных вод крупными реками, перемешивание вод океанов и морей.

Answer 2

Salinity of the Baltic Sea and the Barents Sea

The salinity of the Baltic Sea is generally lower than that of the Barents Sea. This difference can be attributed to several factors.

One of the main reasons for the lower salinity in the Baltic Sea is its limited connection to the open ocean. The Baltic Sea is a semi-enclosed body of water with narrow straits connecting it to the North Sea. As a result, the exchange of water with the open ocean is relatively limited, leading to lower salinity levels.

Another factor influencing the salinity of the Baltic Sea is the large number of rivers that flow into it. These rivers bring freshwater from surrounding land areas, which dilutes the salt content of the sea. The major rivers that contribute to the freshwater input include the Vistula, Oder, and Neva rivers, among others.

Additionally, the Baltic Sea experiences higher rates of evaporation compared to the Barents Sea. Evaporation removes water from the sea, leaving behind higher concentrations of salt. However, due to the limited connection to the open ocean, the Baltic Sea does not receive as much saltwater inflow to compensate for the evaporation, resulting in lower salinity levels.

It is important to note that salinity levels can vary within different parts of the Baltic Sea and the Barents Sea due to local factors such as freshwater inputs, currents, and climate conditions. However, the general trend is that the Baltic Sea has lower salinity compared to the Barents Sea.
