Baltic Sea Recovering

The Baltic Sea - sometimes called the “Nordic Dead Sea” because of the high degree of pollution - is slowly recovering and the negative environmental trend has been broken. For the first time discharges of fertilisers have decreased giving the sea a chance to recover.


The improvement is mainly due to the construction of new treatment works in Poland following the country's entry into the EU. Furthermore farmers in Denmark and Sweden have improved fertiliser management.

It has now been shown that levels of phosphates and nitrogen have declined for the first time, by 3,000 tons and 50,000 tons respectively, according to new research compiled by Fredrik Wulff at Stockholm University, who has made the new calculations on commission from the Baltic Marine Environment Protection Commission (HELCOM).

The first significant effects of the change will not be felt for 30-50 years however, according to a report in the Swedish newspaper Svenska Dagbladet (SvD).

Isn't the major problem the slow turnover of water in the Baltic Sea? It's more stagnant than most other pockets of water if I remember correctly?

Well, the surface water is only very slowly mixing with deeper waters, giving problems with oxygen, but certainly not nearly as bad as for instance in the Black Sea - the slow mixing is partly due to less frequent influx of sea water from the North Sea in recent decades and partly due to pollution. As far as I see it major problems are (and have been) heavy pollution from industry in countries in Eastern Europe, use of fertilisers, and increased sea traffic.

I will anyway come back to the pollution of the Baltic Sea in my next post.
