摘要

Several studies have examined the vertical distribution of bioluminescence in the water column. For example, Widder et al. examined the relationship between the number of bioluminescent organisms as a vertical profile using a bathyphotometer and a variety of physical factors, including temperature, to 250 m depth in the Gulf of Maine. They showed that stimulable bioluminescence, temperature and salinity decrease exponentially from the surface layers. The purpose of this work was to investigate the occurrence of both spontaneous and stimulated bioluminescence in the north-east Atlantic Ocean both in the benthic boundary layer and in the overlying water column at greater depths than previously studied. A high sensitivity video camera mounted on an autonomous lander enabled bioluminescent events to be recorded at depths of up to 6000 m. The lander functions independently of the surface vessel, enabling vertical profiles and benthic experiments to be carried out unaffected by surface weather conditions or other shipboard activities. Another advantage of the lander system is that the camera can be operated close to the seafloor without the need for lights. Such lights are necessary for the operation of manned submersibles and have been implicated in causing damage to the eyes of deep sea invertebrates. The opportunity to deploy the ISIT camera both in April and August enabled preliminary seasonal differences in vertical profiles to be identified. The causes and functions of these differences are suggested. As yet, the identification of luminescent organisms from ISIT video recordings is limited to educated guesses based on the form of the bioluminescence observed.
