Bioluminescence in San Diego, Red Tide makes Avatar footsteps

In 2011 there was an unusual spectacular plankton bloom in San Diego, also called a Red Tide (as it looks red during the day)

At night these algae give off a blue light, bioluminescence, when they are disturbed, creating this real world Avatar-like footsteps.

Enjoy.

That is very cool.

Awesome!

That looks like fun to play around with.

How cool is that!
