Bioluminescence Bathyphotometer for Naval Oceanographic Use
Abstract
The recently completed contract has resulted in the development and proof of a new concept in bathyphotometry for measurement of in situ bioluminescence, incorporating several novel improvements in system control and calibration, hydrodynamic excitation, data transfer and storage, and bioluminescent particle counting. In summary, the bathyphotometer system (hereinafter referred to as HIDEX-1 BPS, for High Intake Defined EXcitation BathyPhotometer System) developed at UCSB is composed of four interactive subsystems: 1) the bathyphotometer subsystem, 2) the CTD subsystem, 3) the deployment subsystem, 4) and the shipboard computer subsystem. The bathyphotometer subsystem is basically a long tube composed of an intake section, a detector section, a thruster section, and an exhaust section. The intake section has a hydrodynamically designed nosecone and stimulus screen, followed by an optical wedge and fiber optic array for bioluminescent particle counting. The detector section of HIDEX-1, which also includes part of the intake section, is composed of white PVC tubing with alternating fiber-optic triplets arrayed longitudinally. The thruster section is a stainless-steel expansion cone flanged to the detector section, having within a coaxially mounted 1/3 HP, DC motor magnetically coupled to a propeller which supplies the thrust for the high flow rates obtainable with this system.
