Bioluminescence in San Diego, Red Tide makes Avatar footsteps

30 May 2013 - 03:35 PM

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.

This is from their website: Aditech Mangrove Videocompact VC-4L6 Mangrove´s new line of LED lights are an industry breakthrough.

The VC-4L6 specially designed for underwater video and photo is supplied with one Solid-State LED module array emitting a staggering 4320 lumens.

Featuring two output levels, the 40W light can dim from high to medium power output levels allowing you to dim lighting for a quick exposure adjustment.
