Here is a clip from the “seaweed-bed” at the Askö laboratory, where most of our experiments are going on. This was filmed in january 2012, with the purpose of checking on the bed, change light/temperature sensor and collect some plates for measure of juvenile growth.
The bed holds about 60 ceramic tiles, onto which we have “sown” bladderwrack and some other wrack crosses. We use the non-glazed side of the tiles since it is important that the surface is porous enough for the seaweed eggs to attach. This makes for some interesting conversations when we buy tiles!
