13. Gelatinous impacts (2400m)

14. Large impact (1100m)

18. Interaction of Luminescent Organisms with an Array Spontaneous Impact Shear Adhesion Trapped Water flow

19. Biological Factors Detected by an Array Abundance of organisms Species Size Status – (reproductive, juvenile, larvae) Locomotor Ability Spontaneous emissions –Inter-specific interactions –Intra-specific interactions Stimulated emissions –Water flow velocity –Impacts –Shear stress –Adhesion –Entrapment

20. Bioluminescence Detected by an Array 1.Decrease with depth 2.Seasonal change 3.Spontaneous luminescence likely to be unimportant 4.Luminescence stimulated by the array may be dominant 5.Adhesion and entrapment of organisms on the array will be be problematic at certain times and depths
