Just before dark, surf photographer Joel Coleman from Saltmotion noticed a large patch of sea that had turned a muddy reddish colour.He whipped out the camera, and punched out some pretty spectacular photos:
What caused this Red Tide?
This ‘red tide’ was a mass of dinoflagellates, a micro-organism that under the right conditions will emit a blue glow when agitated, such as when a wave breaks.
This Bioluminescence is caused by a luciferase enzyme similar but not related to the enzymes in fireflies....and to answer some of your questions:
1. Yes, the photograph, like all photographs from saltmotion are for sale! There are various sizes, framing styles and options to choose from allowing for different budgets.
