Nearly one-sixth of the Baltic Sea is dead. This is equivalent to more than the whole of Denmark surface. DN followed by marine geologist Lovisa Zillén Snowball who clearly sees how the situation has worsened. Researchers have discovered a disturbing trend: Sea eagles have started to become sterile.The ship ”Ocean Surveyor” is equipped with high end appliances and has space for 15 people. For much of the year, measures and analyzes marine geologist Lovisa Zillén Snowball and her colleagues on the Baltic seabed. DN accompanying the casting off of Lake Mälaren, just outside Fittja.- All knowledge of the ocean is important to understanding how the ecosystem works, said Lovisa Zillén Snowball, Director of Geological Survey of Sweden (SGU).
The government has introduced a ”marine billion” in order to reduce the problems of eutrophication in the oceans. According to former Environment Minister Andreas Carlgren (C) was one of the purposes of ”saving the Baltic Sea”. The government has also created a new agency, the Marine Institute.
Despite these measures, the situation in the Baltic Sea to worsen. One of the big problems is eutrophication. Almost one in six, 15 percent, of the bottoms are dead. They cover a larger area than Denmark and among the largest known globally.
– What if it had happened on land. That all life died out in such a large area. There had been a huge environmental disaster – and received many measures. But what is happening under the surface may not be the same attention. The one that gets the most attention with eutrophication are algal blooms. That is what the public sees, says Lovisa Zillén Snowball.
Another 30 percent of the Baltic bottoms suffering from acute asphyxia, according to SMHI.
Lovisa Zillén Snowball and her colleague Anna Apler elevators down a camera to the bottom. On a screen in an office on the ship shows a television screen how it looks in the sea.
They show a number of pictures that were taken last year. The photographs reveal the reality behind the headlines of ”asphyxia” and ”eutrophication”. In the pictures from the seabed of the Baltic Sea, it is completely dead. No plants, no animals or other organisms.
Although the country has the problems of the Baltic Sea had consequences. Scientists have discovered new problems with eagles. At the Norrland coast are clear indications that sea eagles have started to become sterile.
– The Sea Eagles were dying out in the 60s. But environmental toxins such as DDT and PCBs was banned and then added steps in to save the eagles in the country. The populations went up. Now, in recent years the populations begin to decline again in the northern Baltic Sea, especially around Ångermanälven estuary.
Is it because then they start to become sterile?
– You’ve checked the eggs and see how many of them will hatch. The eggs become brittle and never hatch. It is the reproduction of white-tailed eagles that do not work. When one examines the eagle eggs so you can find the old environmental toxins. They probably comes from what we call fiber banks – toxic paper which lies on the sea floor – and that now is no longer stable. It shows our investigations, says Lovisa Zillén Snowball.
The World Wildlife Fund has been critical of the government’s Sea policy. The organization believes that the wind power capacity, more cargo vessels and more ’cruise tourism’ risk together with agriculture and industry further destroy the Baltic Sea.

Scientists are concerned is an extremely odd statement when you are already in the 1950s knew what hydropower causes, in the United States detonates now dams to just save the water from total death.
