Intensified Silicon Intensifier Target (ISIT)

The ISIT (Intensified Silicon Intensifier Target) Lander has been designed to research spontaneous and stimulated bioluminescence in the water column and benthic boundary layer to depths in excess of 4000m.

The lander consists of a low light level (ISIT) camera mounted on an aluminium frame in one of three orientations: Profile - looking vertically down through the water column and stimulating bioluminescence with a mesh screen. Baited - pointed straight down on the sea floor and looking for spontaneous bioluminescence. Rotator - orientated horizontally into the current flow with mesh screen attached to stimulate fauna floating in the current. The camera is continually adjusted by current measurements.

Other pieces of equipment attached to the lander include: a twin acoustic release system to drop iron ballast and refloat the lander to the surface, a tethered mooring to provide buoyancy, a current meter which can measure current speed and direction, water temperature and water depth and a low power microprocessor controller to interface camera, power and current meter and provide data storage.
