500.100 - Deep-sea lander for 6000 m depth:
Lander which is used to document the biodiversity of the deep ocean. In its final version it is equipped with an acoustic releaser, camera, flashes, current meters etc. A deep sea camera system shoots digital stills as well as video and essentially a dead fish or a piece of bait is attached in front of the camera and the animals come in and eat on the bait. The camera will be set up to take a photo about every minute or two minutes and as the animals come and eat occasionally, the camera will take a photo and the scientists are able to catalog the abundance and the diversity of the scavengers.
