| Abstract |
A submarine camera - the luminescence camera - was designed and constructed for the purpose of investigating marine bioluminescence. The camera and strobelight unit contained an electronic control system which utilized a photomultiplier tube as the primary detector . Upon "seeing" a bioluminescent flash, the camera is triggered and a picture of the organism causing the bio-luminescence is obtained. This camera has been used extensively at sea and has produced many pictures. Another submarine camera- the interruption camera -was designed and constructed for the purpose of investigating the abundance of macroscopic life in the ocean. This camera contained an electronic control system which utilized a light beam and crystal-photocell primary detector. When a macroscopic organism interrupts the light beam, the camera is triggered and a picture of the organism is obtained. This camera is more recent than the bioluminescence camera and has not yet been used extensively at sea. |
