Objective The NOCTILUC cruise fits between the studies carried out by ANTARES cooperation to understand bioluminescence, which is one of the optical background noises for the neutrino detector and the SINPAS programme whose aim is to study the metabolic activity of micro organisms. More specifically, this involved measuring: 1) The light yield produced at great depths (2,500 m) by living organisms (bioluminescence). 2) Sedimentation rates, since deposits darken or cloud photosensitive surfaces. 3) Absorption of light. 4) Bacterial activity at great depths which contributes to producing bioluminescence: a - bacteria on glass plate deposits through a biofouling phenomenon. b - bacteria that are free or attached to free particles. The related programmes are: ANTARES and SINPAS.
