Deep water remote video camera footage published

The Shark Research and Conservation Program at the Cape Eluthera Institute in collaboration with Dr Edith Widder from the Ocean Research and Conservation Association has posted some amazing footage of sharpnose sevengill sharks and other creatures taken by a deep water baited video camera known as The Medusa in the Exuma Sound, Bahama. The Medusa is designed for in-situ non-invasive video documentation of creatures and water quality parameters, at a depth of 2000m. It records video in ultra-low light conditions with a highly sensitive camera and DVR recording system, lit by epoxy encapsulated LED arrays that give “far red” illumination at a wavelength of 690 nanometers. At the same time, the unit’s data logger records conductivity, salinity, temperature, pressure, depth, and photosynthetically active radiation. Upon completion of its 72 hour filming operation, a weight is dropped via acoustic release and the Medusa returns to the surface.
