Featured above is bioluminescence at Pirates Bay in south-east Tasmania.
This beautiful sight was caused by a bloom of bioluminescence from noctiluca scintillans. They are single-celled marine organisms that release blue light when disturbed. In this case, they are being disturbed by the movement of the waves. The bioluminescence are acting as particle tracking for the flow of the waves.

second prize – the longer exposure time causing the phytoplankton to appear as streaks in the faster moving parts of the flow is a really cool way to visualize flow speed throughout the waves
Second Prize – I like how bright the colors are to easily visualize the flow.
First prize! I love the sea and the colors in this image, and I love how this happens in nature. It is also easy to see the flow.
First prize, I chose this image because the bright blue glow in the dark sea makes the flow easy to see and looks very beautiful.
