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.
