Gulf of Riga

In the outer sea area of the Gulf, the average number of days with ice in winter increases from 40 in the westernmost part to 60-80 in the middle, and about 100 days in the easternmost part. In severe ice seasons, the number of days of ice formation in the above areas is 100,110-130, and 170, respectively.

The highest depositions of heavy metals over the Baltic Sea can be noted in the south-western part of the Baltic Sea within the Baltic Sea and the Baltic Proper subbasins (Figure 21). Significant levels of lead and cadmium depositions can also be noted in the Gulf of Riga. The total contribution of HELCOM countries to the heavy metals deposition over the Baltic Sea in 2001 amounts to 40%.
