Marine organisms in the Arctic Ocean have a daily rhythm cued on by light – even in the dark season when it is pitch black outside and the ocean has a thick ice cover preventing light from penetrating into the water. But how light sensitive are these organisms – and what light sources affect their behavior? Experiments at UNIS is part of a PhD project aiming at finding out just that.
PhD candidate Henrik Nygård has studied the ecological traits and adaptations of benthic amphipods in the High Arctic. His findings also provide unprecedented insights into the life and ecology of related species living in ice infested waters. Nygård will defend his PhD thesis at UNIS on 2 May 2011.
