In a previous blog I referred to the bioluminescence which was lighting up the waves at Manly. By the time I got back there a couple of nights later with a camera the show had subsided and while the electric shocks were still flashing through the water they were not as frequent. And a camcorder is not the best device for grabbing those sorts of views. But the attached few seconds give you an idea about how spectacular it was – there are some initial glimmers across the tops of the breaking waves and then throughout the wave as it breaks. The dinoflagellate which cause this are marine plankton and in this case are apparently associated with the red algae we have floating off the coast at the moment.
