Greenpeace tours with the Beluga II along the Danish, German and Polish Baltic Sea coasts to test water samples, here near Fehmarn, Germany. The water is tested for nitrate, phosphorous, oxygen levels and multi-resistant germs. The environmental activists are looking for areas that are strongly affected by high levels of fertilizing substances and the so-called 'Dead Zones'.
Problematic chemicals often reach open waters via the rivers and streams, resulting often from spreading manure from factory farming.
