Animation illustrating the deployment and function of the Eye-in-the-Sea
(EITS)
The EITS can be programmed to turn on its red
light and record video at regular intervals. Alternatively it can be
programmed to record when its very sensitive light detector, called
a photomultiplier tube, sees a bioluminescent flash. The flash triggers
the camera to record 3 seconds of video with the lights out, in order
to record the luminescence, and then turns on the red light to reveal
the source of the light. Animation courtesy of Jon Saint
