To learn how organisms apportion space in the open ocean, biological oceanographers have sought to improve temporal and spatial resolution of ocean sampling systems. Their objectives are to simultaneously measure physical, chemical and biological structure in the water column in order to find significant correlations that may reveal underlying processes. Here we report one such correlation between intense peaks of bioluminescence and density discontinuities in the water column. Intensified video recordings made in these bioluminescent “hot spots” were analyzed with a computer image-recognition program that identifies organisms based on the temporal and spatial characteristics of their luminescent displays. Based on this analysis, the source of the “hot spots” was found to be very thin layers (0.5 m) of the bioluminescent copepod Metridia lucens present at from 5 to 100 times average background concentrations.
