On the southwest coast of Norway is the Sognefjord, the second largest in the world. Its freezing, dark water appears uninviting at first look. Yet the beauty of the underwater seascapes and the huge abundance of life there makes us change our mind very quickly. For their size and ecological features the fjords are a unique characteristic habitat in Europe Here the surface water layer has low salinity and a strong gradient is generated with the deeper more salty water called halocline. In general the water is murky and light loses its intensity the first few metres down. The creatures living here have adapted to life in perpetual gloominess.
