I am an marine scientist and, together with collaborators from the Netherlands and US, deploy deep-sea camera systems to film deep-sea cephalopods in their natural habitat.
We use an autonmous, ultra-low-light video imagaing system, called "NAUTILUS" designed by Arctic Rays Subsea Technologies. The system can be deployed as a benthic lander, for filming on the seafloor, or as a drifter, for filming in pelagic waters. The device can record in white light (5700K) and in far-red light (720nm). Additonally, an optical lure, named “Electronic jellyfish” or “eJelly”, sits at the end of a bait bar to mimick bioluminescence.
