As part of a PhD-course organized by BEAM (Baltic Ecosystem Adaptive Management), there were several lectures on the theme “Ecology and Diversity of the Baltic Sea”.
If you are interested in what the benthos looks like, what role the blue mussel plays, or want to know more about the planctonic life of the Baltic Sea, you will find the lectures by klicking HERE.
There is, of course, one or two lectures containing seaweed.
